26000ERRORTier 2 — Caution✅ HIGH confidence

invalid SQL statement name

Category: Invalid SQL Statement NameVersions: All Postgres versions

What this means

SQLSTATE 26000 is raised when a named prepared statement referenced by EXECUTE, DEALLOCATE, or DESCRIBE does not exist — it was never prepared or was already deallocated.

Why it happens

1Calling EXECUTE on a prepared statement name that was never created with PREPARE
2Calling EXECUTE after the prepared statement was deallocated with DEALLOCATE
3Session reconnect after which prepared statements were lost (connections do not persist prepared statements)

How to reproduce

EXECUTE on a non-existent prepared statement.

trigger — this will ERROR

EXECUTE my_stmt(1, 'test'); -- my_stmt was never prepared in this session

ERROR: prepared statement "my_stmt" does not exist

Fix 1: Prepare the statement before executing it

When using explicit SQL-level PREPARE/EXECUTE.

fix

PREPARE my_stmt (INT, TEXT) AS
  SELECT * FROM orders WHERE id = $1 AND status = $2;
EXECUTE my_stmt(1, 'open');

Why this works

PREPARE must be called in the same session before EXECUTE. Prepared statements do not persist across connections.

Fix 2: Use driver-level prepared statements rather than SQL PREPARE

When using application-level drivers (JDBC, psycopg2, node-postgres).

fix

Why this works

Driver-level prepared statements handle preparation transparently and re-prepare automatically on reconnect.
