3 | | -## Features |
4 | | -### Aggregation over INTERVAL Data Types |
5 | | -- **Description**: Pass INTERVAL data types to SUM and AVG aggregate functions. |
6 | | -- **Example**: ```sqlSELECT SUM(interval_column) FROM table_name;` |
7 | | -### Client Describe Call Support for Tag Options |
8 | | -- **Description**: Store and retrieve metadata about database objects using annotations. |
9 | | -- **Example**: `ALTER TABLE table_name ANNOTATE 'key' = 'value';` |
10 | | -### DEFAULT ON NULL for UPDATE Statements |
11 | | -- **Description**: Define columns as DEFAULT ON NULL for update operations. |
12 | | -- **Example**: `UPDATE table_name SET column_name = DEFAULT ON NULL WHERE condition;` |
13 | | -### Data Quality Operators |
14 | | -- **Description**: Introduces PHONIC_ENCODE and FUZZY_MATCH operators for string matching. |
15 | | -- **Example**: `SELECT PHONIC_ENCODE('word'), FUZZY_MATCH('string1', 'string2') FROM dual;` |
16 | | -### Data Use Case Domains |
17 | | -- **Description**: Define and apply constraints for common values like credit card numbers. |
18 | | -- **Example**: `CREATE DOMAIN email_domain AS VARCHAR2(255) CHECK (REGEXP_LIKE(value, '^[\w._%+-]+@[\w.-]+\.[a-zA-Z]{2,}$'));` |
19 | | -### Direct Joins for UPDATE and DELETE Statements |
20 | | -- **Description**: Join target tables in UPDATE and DELETE statements using the FROM clause. |
21 | | -- **Example**: `UPDATE table1 SET column1 = table2.column2 FROM table2 WHERE table1.id = table2.id;` |
22 | | -### GROUP BY Column Alias or Position |
23 | | -- **Description**: Use column aliases or SELECT item positions in GROUP BY clauses. |
24 | | -- **Example**: `SELECT column1 AS col1, SUM(column2) FROM table_name GROUP BY col1;` |
25 | | -### IF [NOT] EXISTS Syntax Support |
26 | | -- **Description**: Support for IF EXISTS and IF NOT EXISTS syntax in DDL operations. |
27 | | -- **Example**: `CREATE TABLE IF NOT EXISTS table_name (column1 datatype);` |
28 | | -### New Database Role for Application Developers |
29 | | -- **Description**: Introduces DB_DEVELOPER_ROLE with necessary privileges for developers. |
30 | | -- **Example**: `GRANT DB_DEVELOPER_ROLE TO user_name;` |
31 | | -### Oracle SQL Access to Kafka |
32 | | -- **Description**: Efficient access to data streams from Apache Kafka and OCI Streaming Service. |
33 | | -- **Example**: `SELECT * FROM kafka_table WHERE topic = 'topic_name';` |
34 | | -### SELECT Without FROM Clause |
35 | | -- **Description**: Run SELECT expression-only queries without a FROM clause. |
36 | | -- **Example**: `SELECT 1+1;` |
37 | | -### SQL BOOLEAN Data Type |
38 | | -- **Description**: Supports ISO SQL standard-compliant BOOLEAN data type. |
39 | | -- **Example**: `CREATE TABLE table_name (column1 BOOLEAN);` |
40 | | -### SQL UPDATE RETURN Clause Enhancements |
41 | | -- **Description**: Enhanced RETURNING INTO clause for reporting old and new values. |
42 | | -- **Example**: `UPDATE table_name SET column1 = 'new_value' RETURNING column1 INTO :old_value;` |
43 | | -### Schema Annotations |
44 | | -- **Description**: Store and retrieve metadata about database objects using name-value pairs. |
45 | | -- **Example**: `ANNOTATE SCHEMA 'key' = 'value';` |
46 | | -### Table Value Constructor |
47 | | -- **Description**: Supports VALUES clause for SELECT, INSERT, and MERGE statements. |
48 | | -- **Example**: `INSERT INTO table_name VALUES (1, 'value');` |
49 | | -### Ubiquitous Search With DBMS_SEARCH Packages |
50 | | -- **Description**: Index multiple schema objects for full-text search using DBMS_SEARCH. |
51 | | -- **Example**: `EXEC DBMS_SEARCH.CREATE_INDEX('index_name', 'table_name');` |
