The invalid_transaction_state error (SQLSTATE 25000) appears when a SQL command is executed in a context that is not allowed for the current transaction state.
invalid_transaction_state (SQLSTATE 25000) means a statement was issued in the wrong transaction context, such as COMMIT outside a block or SET TRANSACTION after commands ran. Roll back or end the transaction, then reorder or wrap statements properly to fix the issue.
invalid_transaction_state
PostgreSQL raises SQLSTATE 25000 when a command conflicts with the current transaction status. The server blocks statements that do not make sense in the present context, protecting ACID guarantees.
The error surfaces immediately after the offending statement.
Subsequent commands in the same batch are skipped until the state is cleared or the session ends.
Commands that require an active transaction, such as SAVEPOINT, run outside any BEGIN block and trigger 25000.
Commands that must run before any read or write, such as SET TRANSACTION ISOLATION LEVEL, raise the error if previous statements have already executed.
Statements that end a transaction twice, like COMMIT followed by another COMMIT, also produce invalid_transaction_state.
Identify the first statement that generated 25000.
Reorder or wrap it within an explicit BEGIN ... COMMIT block, or move pre-transaction settings to the top of the batch.
If the session is stuck, issue ROLLBACK to reset the state, then resend the commands in the correct order.
Running SET TRANSACTION after a SELECT causes 25000. Place the SET immediately after BEGIN.
Executing COMMIT when no transaction is open triggers the error.
Remove the extra COMMIT or surround the logic with BEGIN.
Opening a nested transaction with BEGIN inside an existing block is not allowed. Use SAVEPOINT instead.
Start each script with BEGIN and end with COMMIT or ROLLBACK.
Keep session settings at the top.
Check client libraries for auto-commit behavior and disable it when manual transaction management is required.
Use Galaxy's linting and AI copilot to flag misplaced COMMIT or SET commands before they hit the database.
25P02 current_transaction_is_aborted occurs when an earlier error puts the session in aborted state. Issue ROLLBACK.
0A000 feature_not_supported appears if you attempt SAVEPOINT in auto-commit mode.
Surround with BEGIN.
2200L not_null_violation can cascade into 25P02 if not handled, requiring a rollback before new statements.
.
No. PostgreSQL blocks further commands until you roll back or end the session.
Autocommit reduces exposure but 25000 can still occur if you send an inappropriate command like SET TRANSACTION.
Galaxy's AI copilot analyzes query order, warns about misplaced transaction commands, and suggests fixes before execution.
invalid_transaction_state exists in every supported PostgreSQL version. Behavior is consistent across releases.
