It will take a generic argument that is the shape of the data. So if you do `q.from({ user: usersCollection })` then the `RefProxy` will have a type like: + +```ts +RefProxy<{ user: User }> +``` + +The callback should return an expression. + +There should be a generic context that is passed down through all the methods to new query builders. This should be used to infer the type of the query, providing type safety and autocompletion. It should also be used to infer the type of the result of the query. + +### `from()` + +`from` takes a single argument, which is an object with a single key, the alias, and a value which is a collection or a sub query. + +### `select()` + +`select` takes a callback, which is passed a `RefProxy` object. The callback should return an object with key/values paires, with the value being an expression. + +### `join()` + +`join` takes three arguments: + +- an object with a single key, the alias, and a value which is a collection or a sub query +- a callback that is passed a `RefProxy` object of the current shape along with the new joined shape. It needs to return an `eq` expression. It will extract the left and right sides of the expression and use them as the left and right sides of the join in the IR. + +### `where()` / `having()` + +`where` and `having` take a callback, which is passed a `RefProxy` object. The callback should return an expression. This is evaluated to a boolean value for each row in the query, filtering out the rows that are false. + +`having` is the same as `where`, but is applied after the `groupBy` clause. + +### `groupBy()` + +`groupBy` takes a callback, which is passed a `RefProxy` object. The callback should return an expression. This is evaluated to a value for each row in the query, grouping the rows by the value. + +### `limit()` / `offset()` + +`limit` and `offset` take a number. + +### `orderBy()` + +`orderBy` takes a callback, which is passed a `RefProxy` object. The callback should return an expression that is evaluated to a value for each row in the query, and the rows are sorted by the value. + + +# Example queries: + +## 1. Simple filtering with multiple conditions + +```js +const activeUsers = useLiveQuery((q) => + q + .from({ user: usersCollection }) + .where(({ user }) => and( + eq(user.status, 'active'), + gt(user.lastLoginAt, new Date('2024-01-01')) + )) + .select(({ user }) => ({ + id: user.id, + name: user.name, + email: user.email, + })) +); +``` + +## 2.

processing (collections and sub-queries) +- Coordinates all pipeline stages + +### Expression Evaluator (`evaluators.ts`) +- Evaluates expressions against namespaced row data +- Supports all expression types: refs, values, functions, aggregates +- Implements comparison operators: `eq`, `gt`, `gte`, `lt`, `lte` +- Implements boolean operators: `and`, `or`, `not` +- Implements string operators: `like`, `ilike` +- Implements string functions: `upper`, `lower`, `length`, `concat`, `coalesce` +- Implements math functions: `add`, `subtract`, `multiply`, `divide` +- Implements array operations: `in` + +### Pipeline Processors +- **Joins (`joins.ts`)**: Handles all join types (inner, left, right, full, cross) +- **Order By (`order-by.ts`)**: Implements sorting with multiple columns and directions +- **Group By (`group-by.ts`)**: Basic grouping support (simplified implementation) +- **Select (`select.ts`)**: Processes SELECT clauses with expression evaluation + +## Features Implemented + +### ✅ Basic Query Operations +- FROM clause with collections and sub-queries +- SELECT clause with expression evaluation +- WHERE clause with complex filtering +- ORDER BY with multiple columns and directions + +### ✅ Expression System +- Reference expressions (`ref`) +- Literal values (`val`) +- Function calls (`func`) +- Comprehensive operator support + +### ✅ String Operations +- LIKE/ILIKE pattern matching with SQL wildcards (% and _) +- String functions (upper, lower, length, concat, coalesce) + +### ✅ Boolean Logic +- AND, OR, NOT operations +- Complex nested conditions + +### ✅ Comparison Operations +- All standard comparison operators +- Proper null handling +- Type-aware comparisons + +### ⚠️ Partial Implementation +- **GROUP BY**: Basic structure in place, needs full aggregation logic +- **Aggregate Functions**: Placeholder implementation for single-row operations +- **HAVING**: Basic filtering support + +### ❌ Not Yet Implemented +-

API for building queries. The implementation includes: - -## Key Components Implemented - -### 1. **IR (Intermediate Representation)** (`ir.ts`) - -- **Query structure**: Complete IR with from, select, join, where, groupBy, having, orderBy, limit, offset -- **Expression types**: Ref, Value, Func, Agg classes for representing different expression types -- **Source types**: CollectionRef and QueryRef for different data sources - -### 2. **RefProxy System** (`query-builder/ref-proxy.ts`) - -- **Dynamic proxy creation**: Creates type-safe proxy objects that record property access paths -- **Automatic conversion**: `toExpression()` function converts RefProxy objects to IR expressions -- **Helper utilities**: `val()` for creating literal values, `isRefProxy()` for type checking - -### 3. **Type System** (`query-builder/types.ts`) - -- **Context management**: Comprehensive context type for tracking schema and state -- **Type inference**: Proper type inference for schemas, joins, and result types -- **Callback types**: Type-safe callback signatures for all query methods - -### 4. **Query Builder** (`query-builder/index.ts`) - -- **Fluent API**: Chainable methods that return new builder instances -- **Method implementations**: - - `from()` - Set the primary data source - - `join()` - Add joins with callback-based conditions - - `where()` - Filter with callback-based conditions - - `having()` - Post-aggregation filtering - - `select()` - Column selection with transformations - - `groupBy()` - Grouping with callback-based expressions - - `orderBy()` - Sorting with direction support - - `limit()` / `offset()` - Pagination support - -### 5. **Expression Functions** (`expresions/functions.ts`) - -- **Operators**: eq, gt, gte, lt, lte, and, or, not, in, like, ilike -- **Functions**: upper, lower, length, concat, coalesce, add -- **Aggregates**: count, avg, sum, min, max -- **Auto-conversion**: All functions accept RefProxy or literal values and convert automatically - -## API Examples - -### Basic Query - -```ts -const query = buildQuery((q) => - q - .from({ users: usersCollection }) - .where(({ users }) => eq(users.active, true)) - .select(({ users }) => ({ id: users.id, name: users.name })) -) -``` - -### Join Query - -```ts -const query = buildQuery((q) => - q - .from({ posts: postsCollection }) - .join({ users: usersCollection }, ({ posts, users }) => - eq(posts.userId, users.id) - ) - .select(({ posts, users }) => ({ - title: posts.title, - authorName: users.name, - })) -) -``` - -### Aggregation Query - -```ts -const query = buildQuery((q) => - q - .from({ orders: ordersCollection }) - .groupBy(({ orders }) => orders.status) - .select(({ orders }) => ({ - status: orders.status, - count: count(orders.id), - totalAmount: sum(orders.amount), - })) -) -``` - -### Type-Safe Expressions - -```ts -const query = buildQuery((q) => - q - .from({ user: usersCollection }) - .where(({ user }) => eq(user.age, 25)) // ✅ number === number - .where(({ user }) => eq(user.name, "John")) // ✅ string === string - .where(({ user }) => gt(user.age, 18)) // ✅ number > number - .select(({ user }) => ({ - id: user.id, // RefProxy - nameLength: length(user.name), // string function - isAdult: gt(user.age, 18), // boolean result - })) -) -``` - -## Key Features - -### ✅ **Type Safety** - -- Full TypeScript support with proper type inference -- RefProxy objects provide autocomplete for collection properties -- Compile-time checking of column references and expressions -- **Smart expression validation**: Functions prefer compatible types (e.g., `eq(user.age, 25)` where both sides are numbers) -- **IDE support**: RefProxy objects show proper types (`user.age` shows as `RefProxy`) -- **Flexible but guided**: Accepts any value when needed but provides type hints for the happy path - -### ✅ **Callback-Based API** - -- Clean, readable syntax using destructured parameters -- No string-based column references -- IDE autocomplete and refactoring support - -### ✅ **Expression System** - -- Comprehensive set of operators, functions, and aggregates -- Automatic conversion between RefProxy and Expression objects -- Support for nested expressions and complex conditions -- **Type-safe expressions**: Functions validate argument types (e.g., `eq(user.age, 25)` ensures both sides are compatible) - -### ✅ **Fluent Interface** - -- Chainable methods that return new builder instances -- Immutable query building (no side effects) -- Support for composable sub-queries - -### ✅ **IR Generation** - -- Clean separation between API and internal representation -- Ready for compilation to different query formats -- Support for advanced features like CTEs and sub-queries - -## Implementation Status - -### Completed ✅ - -- [x] Basic query builder structure -- [x] RefProxy system for type-safe property access -- [x] All core query methods (from, join, where, select, etc.) -- [x] Expression functions and operators -- [x] Type inference for schemas and results -- [x] IR generation from builder state -- [x] TypeScript compilation without errors - -### Future Enhancements 🔮 - -- [ ] Query compiler implementation (separate phase) -- [ ] Advanced join types and conditions -- [ ] Window functions and advanced SQL features -- [ ] Query optimization passes -- [ ] Runtime validation of query structure - -## Testing - -Basic test suite included in `simple-test.ts` demonstrates: - -- From clause functionality -- Where conditions with expressions -- Select projections -- Group by with aggregations -- buildQuery helper function - -## Export Structure - -The main exports are available from `packages/db/src/query2/index.ts`: - -- Query builder classes and functions -- Expression functions and operators -- Type utilities and IR types -- RefProxy helper functions - -This implementation provides a solid foundation for the new query builder system while maintaining the API design specified in the README.md file. diff --git a/packages/db/src/query2/query-builder/functions.ts b/packages/db/src/query2/builder/functions.ts similarity index 100% rename from packages/db/src/query2/query-builder/functions.ts rename to packages/db/src/query2/builder/functions.ts diff --git a/packages/db/src/query2/query-builder/index.ts b/packages/db/src/query2/builder/index.ts similarity index 100% rename from packages/db/src/query2/query-builder/index.ts rename to packages/db/src/query2/builder/index.ts diff --git a/packages/db/src/query2/query-builder/ref-proxy.ts b/packages/db/src/query2/builder/ref-proxy.ts similarity index 100% rename from packages/db/src/query2/query-builder/ref-proxy.ts rename to packages/db/src/query2/builder/ref-proxy.ts diff --git a/packages/db/src/query2/query-builder/types.ts b/packages/db/src/query2/builder/types.ts similarity index 100% rename from packages/db/src/query2/query-builder/types.ts rename to packages/db/src/query2/builder/types.ts diff --git a/packages/db/src/query2/compiler/README.md b/packages/db/src/query2/compiler/README.md deleted file mode 100644 index b91d4cb35..000000000 --- a/packages/db/src/query2/compiler/README.md +++ /dev/null @@ -1,115 +0,0 @@ -# Query2 Compiler - -This directory contains the new compiler for the query2 system that translates the intermediate representation (IR) into D2 pipeline operations. - -## Architecture - -The compiler consists of several modules: - -### Core Compiler (`index.ts`) - -- Main entry point with `compileQuery()` function -- Orchestrates the compilation process -- Handles FROM clause processing (collections and sub-queries) -- Coordinates all pipeline stages - -### Expression Evaluator (`evaluators.ts`) - -- Evaluates expressions against namespaced row data -- Supports all expression types: refs, values, functions, aggregates -- Implements comparison operators: `eq`, `gt`, `gte`, `lt`, `lte` -- Implements boolean operators: `and`, `or`, `not` -- Implements string operators: `like`, `ilike` -- Implements string functions: `upper`, `lower`, `length`, `concat`, `coalesce` -- Implements math functions: `add`, `subtract`, `multiply`, `divide` -- Implements array operations: `in` - -### Pipeline Processors - -- **Joins (`joins.ts`)**: Handles all join types (inner, left, right, full, cross) -- **Order By (`order-by.ts`)**: Implements sorting with multiple columns and directions -- **Group By (`group-by.ts`)**: Basic grouping support (simplified implementation) -- **Select (`select.ts`)**: Processes SELECT clauses with expression evaluation - -## Features Implemented - -### ✅ Basic Query Operations - -- FROM clause with collections and sub-queries -- SELECT clause with expression evaluation -- WHERE clause with complex filtering -- ORDER BY with multiple columns and directions - -### ✅ Expression System - -- Reference expressions (`ref`) -- Literal values (`val`) -- Function calls (`func`) -- Comprehensive operator support - -### ✅ String Operations - -- LIKE/ILIKE pattern matching with SQL wildcards (% and \_) -- String functions (upper, lower, length, concat, coalesce) - -### ✅ Boolean Logic - -- AND, OR, NOT operations -- Complex nested conditions - -### ✅ Comparison Operations - -- All standard comparison operators -- Proper null handling -- Type-aware comparisons - -### ⚠️ Partial Implementation - -- **GROUP BY**: Basic structure in place, needs full aggregation logic -- **Aggregate Functions**: Placeholder implementation for single-row operations -- **HAVING**: Basic filtering support - -### ❌ Not Yet Implemented - -- **LIMIT/OFFSET**: Structure in place but not implemented -- **WITH (CTEs)**: Not implemented -- **Complex Aggregations**: Needs integration with GROUP BY - -## Usage -

-## How the query builder will work - -Each of the methods on the QueryBuilder will return a new QueryBuilder object. - -Those that take a callback are passed a `RefProxy` object which records the path to the property. It will take a generic argument that is the shape of the data. So if you do `q.from({ user: usersCollection })` then the `RefProxy` will have a type like: - -```ts -RefProxy<{ user: User }> -``` - -The callback should return an expression. - -There should be a generic context that is passed down through all the methods to new query builders. This should be used to infer the type of the query, providing type safety and autocompletion. It should also be used to infer the type of the result of the query. - -### `from()` - -`from` takes a single argument, which is an object with a single key, the alias, and a value which is a collection or a sub query. - -### `select()` - -`select` takes a callback, which is passed a `RefProxy` object. The callback should return an object with key/values paires, with the value being an expression. - -### `join()` - -`join` takes three arguments: - -- an object with a single key, the alias, and a value which is a collection or a sub query -- a callback that is passed a `RefProxy` object of the current shape along with the new joined shape. It needs to return an `eq` expression. It will extract the left and right sides of the expression and use them as the left and right sides of the join in the IR. - -### `where()` / `having()` - -`where` and `having` take a callback, which is passed a `RefProxy` object. The callback should return an expression. This is evaluated to a boolean value for each row in the query, filtering out the rows that are false. - -`having` is the same as `where`, but is applied after the `groupBy` clause. - -### `groupBy()` - -`groupBy` takes a callback, which is passed a `RefProxy` object. The callback should return an expression. This is evaluated to a value for each row in the query, grouping the rows by the value. - -### `limit()` / `offset()` - -`limit` and `offset` take a number. - -### `orderBy()` - -`orderBy` takes a callback, which is passed a `RefProxy` object. The callback should return an expression that is evaluated to a value for each row in the query, and the rows are sorted by the value. - -# Example queries: - -## 1. Simple filtering with multiple conditions - -```js -const activeUsers = useLiveQuery((q) => - q - .from({ user: usersCollection }) - .where(({ user }) => - and( - eq(user.status, "active"), - gt(user.lastLoginAt, new Date("2024-01-01")) - ) - ) - .select(({ user }) => ({ - id: user.id, - name: user.name, - email: user.email, - })) -) -``` - -## 2. Using string functions and LIKE operator - -```js -const searchUsers = useLiveQuery((q) => - q - .from({ user: usersCollection }) - .where(({ user }) => - or(like(lower(user.name), "%john%"), like(lower(user.email), "%john%")) - ) - .select(({ user }) => ({ - id: user.id, - displayName: upper(user.name), - emailLength: length(user.email), - })) -) -``` - -## 3. Pagination with limit and offset - -```js -const paginatedPosts = useLiveQuery( - (q) => - q - .from({ post: postsCollection }) - .where(({ post }) => eq(post.published, true)) - .orderBy(({ post }) => post.createdAt, "desc") - .limit(10) - .offset(page * 10) - .select(({ post }) => ({ - id: post.id, - title: post.title, - excerpt: post.excerpt, - publishedAt: post.publishedAt, - })), - [page] -) -``` - -## 4. Complex aggregation with HAVING clause - -```js -const popularCategories = useLiveQuery((q) => - q - .from({ post: postsCollection }) - .join({ category: categoriesCollection }, ({ post, category }) => - eq(post.categoryId, category.id) - ) - .groupBy(({ category }) => category.name) - .having(({ post }) => gt(count(post.id), 5)) - .select(({ category, post }) => ({ - categoryName: category.name, - postCount: count(post.id), - avgViews: avg(post.views), - totalViews: sum(post.views), - })) - .orderBy(({ post }) => count(post.id), "desc") -) -``` - -## 5. Using IN operator with array - -```js -const specificStatuses = useLiveQuery((q) => - q - .from({ task: tasksCollection }) - .where(({ task }) => and( - in(task.status, ['pending', 'in_progress', 'review']), - gte(task.priority, 3) - )) - .select(({ task }) => ({ - id: task.id, - title: task.title, - status: task.status, - priority: task.priority, - })) -); -``` - -## 6. Multiple joins with different collections - -```js -const orderDetails = useLiveQuery( - (q) => - q - .from({ order: ordersCollection }) - .join({ customer: customersCollection }, ({ order, customer }) => - eq(order.customerId, customer.id) - ) - .join({ product: productsCollection }, ({ order, product }) => - eq(order.productId, product.id) - ) - .where(({ order }) => gte(order.createdAt, startDate)) - .select(({ order, customer, product }) => ({ - orderId: order.id, - customerName: customer.name, - productName: product.name, - total: order.total, - orderDate: order.createdAt, - })) - .orderBy(({ order }) => order.createdAt, "desc"), - [startDate] -) -``` - -## 7. Using COALESCE and string concatenation - -```js -const userProfiles = useLiveQuery((q) => - q.from({ user: usersCollection }).select(({ user }) => ({ - id: user.id, - fullName: concat([user.firstName, " ", user.lastName]), - displayName: coalesce([user.nickname, user.firstName, "Anonymous"]), - bio: coalesce([user.bio, "No bio available"]), - })) -) -``` - -## 8. Nested conditions with NOT operator - -```js -const excludedPosts = useLiveQuery((q) => - q - .from({ post: postsCollection }) - .where(({ post }) => - and( - eq(post.published, true), - not(or(eq(post.categoryId, 1), like(post.title, "%draft%"))) - ) - ) - .select(({ post }) => ({ - id: post.id, - title: post.title, - categoryId: post.categoryId, - })) -) -``` - -## 9. Time-based analytics with date comparisons - -```js -const monthlyStats = useLiveQuery( - (q) => - q - .from({ event: eventsCollection }) - .where(({ event }) => - and(gte(event.createdAt, startOfMonth), lt(event.createdAt, endOfMonth)) - ) - .groupBy(({ event }) => event.type) - .select(({ event }) => ({ - eventType: event.type, - count: count(event.id), - firstEvent: min(event.createdAt), - lastEvent: max(event.createdAt), - })), - [startOfMonth, endOfMonth] -) -``` - -## 10.

Updated GROUP BY Processor (`group-by.ts`) -- Works with existing `__select_results` from early SELECT processing -- Updates `__select_results` with aggregate computations -- Eliminates internal SELECT handling duplication -- Simplified HAVING clause evaluation using `__select_results` - -#### 4.
