ABORT [ abort_message ] [ FROM option ] [ WHERE abort_condition ]
- Text of the message to be returned when the transaction is terminated.
- If abort_message is not specified, the message defaults to “user-generated transaction ABORT”.
- FROM option
- A clause that is required only if the WHERE clause includes subqueries or if the request is preceded with a temporal qualifier.
- You can code scalar subqueries as an expression within a derived table in FROM clause conditions in the same way you can specify them for a SELECT request.
- See Scalar Subqueries and Rules for Using Scalar Subqueries in ABORT Statements. Note, however, that you cannot code a derived table as a scalar subquery.
- The contents of the FROM option are described in FROM Clause.
- WHERE abort_condition
- A clause that introduces a conditional expression whose result must evaluate to TRUE if the transaction is to be rolled back. The expression can specify aggregate operations and scalar subqueries.
- If the WHERE clause is omitted, termination is unconditional. See WHERE Clause.
- If you specify the value for a row-level security constraint, it must be expressed in its encoded form.
- The WHERE condition specifies an expression whose result must evaluate to TRUE if termination is to occur. If the result is FALSE, transaction processing continues.
