Test coverage for CONSTRAINT support to close #2360 (#2373)
Column-level Foreign Key NULL Handling **Location:** `src/60createtable.js:169-184` **Problem:** Foreign keys rejected NULL values (treated NaN as invalid) **Fix:** Updated to check for `undefined`, `null`, and `NaN` to properly allow NULL in foreign keys Column-level Foreign Key `fk` Flag **Location:** `src/60createtable.js:183` **Problem:** Column-level foreign keys missing `fk: true` flag **Fix:** Added flag for consistency with table-level foreign keys CHECK Constraint NULL Semantics - `src/50expression.js:510` - Expression NULL detection - `src/60createtable.js:377-384,647-655` - CHECK validation logic CHECK constraints failed when NULL was involved - Updated expression compiler to recognize NaN as NULL - Changed validation from `if (!check.fn(r))` to `if (check.fn(r) === false)` per SQL-99 standard CHECK/FK Function Signatures **Location:** `src/60createtable.js:125-129,218-219` **Problem:** CHECK functions couldn't access `alasql` object for built-in functions **Fix:** Updated signatures from `(r)` to `(r,params,alasql)` with matching call sites Test SQL Syntax **Location:** `test/test325.js:14-37` **Problem:** Missing comma between constraints **Fix:** Corrected SQL syntax, kept NONCLUSTERED/CLUSTERED (SQL Server extensions that parser supports) CURRENT_TIMESTAMP Test Robustness **Location:** `test/test324.js:158-163` **Problem:** Test assumed CURRENT_TIMESTAMP always returns string, but can return Date object **Fix:** Updated test to handle both string (when dateAsString=true) and Date object formats SOURCE Command Bug Fix **Location:** `src/15utility.js:352` **Problem:** ReferenceError - catch block referenced undefined variable 'err' instead of 'e' **Fix:** Changed `error(err, null)` to `error(e, null)` to use the caught exception variable Test324 Test 20 Enabled **Location:** `test/test324.js:175-180`, `test/test324.sql` **Problem:** Test skipped due to SOURCE bug and SQL syntax incompatibilities **Fix:** - Fixed SOURCE command bug - Created tempdb database before SOURCE - Removed SQL Server-specific `$` prefix from MONEY values in test324.sql --------- Co-authored-by: copilot-swe-agent[bot] <[email protected]> Co-authored-by: mathiasrw <[email protected]>
