Synonyms

For more information check the Synonym translation reference.

Synonyms used inside PL/SQL blocks are changed to the referenced object and the Schema will be added if necessary.

Implicit Schema added

When the procedure or function is inside a schema and the synonym is inside that schema, but it is being used without the schema, the converted code will add the schema.

Oracle

IN -> Oracle_01.sql

CREATE TABLE schema_one.TABLE_TEST1(
    COL1 INTEGER,
    COL2 DATE DEFAULT SYSDATE
    );

CREATE OR REPLACE SYNONYM schema_one.MY_SYNONYM1 FOR schema_one.TABLE_TEST1;

create or replace procedure schema_one.procedure1  as
returnval integer;
begin
    select col1 into returnval from my_synonym1;
end; 

Snowflake

OUT -> Oracle_01.sql

CREATE OR REPLACE TABLE schema_one.TABLE_TEST1 (
        COL1 INTEGER,
        COL2 TIMESTAMP /*** SSC-FDM-OR0042 - DATE TYPE COLUMN HAS A DIFFERENT BEHAVIOR IN SNOWFLAKE. ***/ DEFAULT CURRENT_TIMESTAMP()

                    schema_one.TABLE_TEST1;
        END;
        $$;

Schema of referenced object added

When the synonym references an object that is in a specific schema, the schema name will be added to the referenced object.

CREATE OR REPLACE SYNONYM MY_SYNONYM2 FOR schema_one.TABLE_TEST1;

create or replace procedure procedure2  as
returnval integer;
begin
    select col1 into returnval from my_synonym2;
