Severity

Low

Description

This EWI is added when PRAGMA EXCEPTION_INIT function is invoked within a procedure. Exception Name and SQL Code of the exceptions are set in the RAISE function. When it is converted to Snowflake Scripting, the SQL Code is added to the Exception declaration, however, some code values may be invalid in Snowflake Scripting.

Example Code

Input Code:

IN -> Oracle_01.sql

CREATE OR REPLACE PROCEDURE EXCEPTION_DECLARATION_SAMPLE AUTHID DEFINER IS
  NEW_EXCEPTION EXCEPTION;
  PRAGMA EXCEPTION_INIT(NEW_EXCEPTION, -63);
  NEW_EXCEPTION2 EXCEPTION;
  PRAGMA EXCEPTION_INIT ( NEW_EXCEPTION2, -20100 );
BEGIN

  IF true THEN
    RAISE NEW_EXCEPTION;
  END IF;

EXCEPTION
    WHEN NEW_EXCEPTION THEN
        --Handle Exceptions
        NULL;
END;
/

Output Code:

Snowflake script

OUT -> Oracle_01.sql

CREATE OR REPLACE PROCEDURE EXCEPTION_DECLARATION_SAMPLE ()
RETURNS VARCHAR
LANGUAGE SQL
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
