Output Code

Source Code

Suppose this is the input source code you've migrated:

IN -> Teradata_01.sql

CREATE TABLE! TABLE_Invalid
(
  COL1 VARCHAR2(255),
  COL2 VARCHAR2
);

CREATE TABLE TABLE1
(
  COL1 INT,
  COL2 VARCHAR2!
);

CREATE OR REPLACE VIEW VIEW1
AS
    SELECT 
        UNKOWN_FUNCTION(1), 
        COL1, 
        COL2 
    FROM TABLE1
;

Output code

How to interpret the output code?

• There is one parsing error in line number one. This is because of an invalid token CREATE TABLE!

• There is another parsing error on line 10. This is because of an invalid tokenVARCHAR2!

• There is an unknown function UNKNOWN_FUNCTION , which is translated as is, but warning SSC-EWI-0073 is added to indicate that this is something that has not been checked yet and therefore, the functional equivalence cannot be assured.
