SQLite vs PostgreSQL Syntax Differences

Apex Forge SQL executes in an in-memory SQLite sandbox. When copying verified queries to production PostgreSQL environments, keep these key dialect differences in mind.

Feature	SQLite (Apex Forge Sandbox)	PostgreSQL (Production)
Auto-Increment Key	`INTEGER PRIMARY KEY AUTOINCREMENT`	`SERIAL PRIMARY KEY` or `IDENTITY`
Current UTC Timestamp	`CURRENT_TIMESTAMP` (UTC text string)	`NOW()` or `CURRENT_TIMESTAMP`
Date Extraction	`strftime('%Y-%m', date_col)`	`TO_CHAR(date_col, 'YYYY-MM')`
String Concatenation	`col1 \|\| ' ' \|\| col2`	`CONCAT(col1, ' ', col2)` or `\|\|`
Boolean Values	`0` or `1` (integers)	`TRUE` or `FALSE` (native boolean)
Pattern Matching	`LIKE` (case-insensitive for ASCII)	`ILIKE` (case-insensitive)
