Sam Jewell	c9e929e2e6	SQL Expressions: Allow more MySQL AST node-types (#102973) ... * SQL Expressions: Add Null-literal node * Retain some order in the code - put NullVal with BoolVal * Add support for `IN` keyword * Add GROUP_CONCAT keyword * Add COLLATE keyword From Claude: The test case demonstrates a simple use of COLLATE with a string literal, but in real MySQL queries, COLLATE is often used in more complex scenarios like: 1. String comparisons: `SELECT * FROM table WHERE name COLLATE utf8mb4_bin = 'John'` 2. Sorting: `SELECT * FROM table ORDER BY name COLLATE utf8mb4_unicode_ci` 3. JOINs: `SELECT * FROM table1 JOIN table2 ON table1.name COLLATE utf8mb4_bin = table2.name` The COLLATE clause is particularly useful when you need case-sensitive comparisons (utf8mb4_bin) or specific language-aware sorting rules.	9 months ago

Sam Jewell	21b9d45ca6	SQL Expressions: Add CASE/WHEN nodes and fixes (and test) for functions just added to allowlist (#102040) ... * SQL Expressions: Add CASE/WHEN SQL nodes to allowlist * Fixed and test for functions added in #102011 * Add remaining functions to the test-case These are mostly aliases, so the LLM chose to omit them originally. But adding now for completeness * Fix ordering of allowed nodes	10 months ago
