OBJECT_ID

Description

This function returns the database object identification number of a schema-scoped object.(OBJECT_ID in Transact-SQL).

SQL Server syntax

OBJECT_ID ( '[ database_name . [ schema_name ] . | schema_name . ]   
  object_name' [ ,'object_type' ] )

Sample Source Patterns

1. Default transformation

SQL Server

IN -> SqlServer_01.sql

IF OBJECT_ID_UDF('DATABASE2.DBO.TABLE1') is not null) THEN
            DROP TABLE IF EXISTS TABLE1;
        END IF;

Snowflake SQL

OUT -> SqlServer_01.sql

BEGIN
-- ** SSC-EWI-0001 - UNRECOGNIZED TOKEN ON LINE 1 COLUMN 0 OF THE SOURCE CODE STARTING AT 'IF'. EXPECTED 'If Statement' GRAMMAR. **
--IF OBJECT_ID_UDF('DATABASE2.DBO.TABLE1') is not null) THEN
--** SSC-FDM-0007 - MISSING DEPENDENT OBJECT "TABLE1" **
DROP TABLE IF EXISTS TABLE1;
END;

2. Unknown database

SQL Server

Code:

IF OBJECT_ID_UDF('DATABASE1.DBO.TABLE1') is not null) THEN
            DROP TABLE IF EXISTS TABLE1;
        END IF;

Snowflake SQL

Code:

 IF (
 OBJECT_ID_UDF('DATABASE1.DBO.TABLE1') is not null) THEN
     DROP TABLE IF EXISTS TABLE1;
 END IF;

3. Different object names

SQL Server

Code:

IF OBJECT_ID_UDF('DATABASE1.DBO.TABLE2') is not null) THEN
            DROP TABLE IF EXISTS TABLE1;
        END IF;

Snowflake SQL

Code:

 IF (
 OBJECT_ID_UDF('DATABASE1.DBO.TABLE2') is not null) THEN
     DROP TABLE IF EXISTS TABLE1;
 END IF;

Known issues

1. OBJECT_ID_UDF function has different behavior in certain cases

OBJECT_ID returns the object identification number but the OBJECT_ID_UDF returns a boolean value, so that they are equivalent only when OBJECT_ID is used with not null condition.
