Stored Procedure - Language Selection SQL vs Javascript

 Choosing between LANGUAGE JAVASCRIPT and LANGUAGE SQL (Snowflake Scripting) for stored procedures depends on what you’re trying to accomplish.

Use SQL scripting when:

• You're mostly executing SQL statements.

• You want clean, readable procedures.

• You're doing DML (INSERT, UPDATE, DELETE).

Use JavaScript when:

• You need complex procedural logic not easily expressed in SQL.

• You want to build dynamic SQL more flexibly.

• You want to loop through result sets or arrays.
