LOG ERROR

Some parts in the output code are omitted for clarity reasons.

Description

The FORALL statement runs one DML statement multiple times, with different values in the VALUES and WHERE clauses. (Oracle PL/SQL Language Reference FORALL Statement).

Oracle Syntax

FORALL index IN bounds_clause [ SAVE ] [ EXCEPTIONS ] dml_statement ;

Snowflake Scripting has no direct equivalence with the FORALL statement, however can be emulated with different workarounds to get functional equivalence.
