The SELECT COUNT(*) table-existence probe in all four driver managers threw an uncaught PDOException when the table did not exist and PDO was in ERRMODE_EXCEPTION mode. Wrapping the probe in try/catch allows the method to proceed to CREATE TABLE as intended. Closes modxcms#207.

What changed and why
The
createObjectContainer()method in all four driver managers probes for table existence with a bareSELECT COUNT(*) FROM {table}. On MySQL 8+ (and any driver configured withPDO::ERRMODE_EXCEPTION), this query throws aPDOExceptionwhen the table does not yet exist. The exception was not caught, causing the method to abort instead of proceeding toCREATE TABLE. Closes #207.Files and methods changed
src/xPDO/Om/mysql/xPDOManager.php—createObjectContainer(): wrap existence probe in try/catchsrc/xPDO/Om/pgsql/xPDOManager.php—createObjectContainer(): samesrc/xPDO/Om/sqlite/xPDOManager.php—createObjectContainer(): samesrc/xPDO/Om/sqlsrv/xPDOManager.php—createObjectContainer(): sameCross-driver impact
All four drivers (MySQL, PostgreSQL, SQLite, SQL Server) contained the identical bug. All four are fixed identically.
Test coverage
Added
test/xPDO/Test/Om/xPDOManagerCreateObjectContainerTest.phpwith two test methods:testCreateObjectContainerOnNonExistentTableReturnsTrue— primary regression test; forces ERRMODE_EXCEPTION and verifies no PDOException propagates when table is absenttestCreateObjectContainerOnExistingTableReturnsTrue— idempotency test; verifies the existing-table early-return path still worksTests run against all CI drivers (SQLite, MySQL, PostgreSQL).
Breaking change assessment
No public API signature or return type changed. The method already returned
bool. When a table is absent the method previously threw; now it correctly proceeds to CREATE TABLE and returnstrueon success. Safe for patch-level consumers.AI Disclosure
This fix was developed using an AI-assisted workflow. AI agents (Claude) wrote the code, tests, and initial code review under the direction of the project maintainer (@opengeek), who reviewed the final diff, validated the approach, and takes responsibility for the submission.
