Severity

High

Description

A DML statement in TPT could not be processed and converted by the tool. This can happen for reasons like using concatenation with script variables or using escaping quotes inside the DML statement.

Example code

Input Code:

IN -> Teradata_01.tpt

-- Script1.tpt
DEFINE JOB load_job
DESCRIPTION 'LOAD TABLE FROM A FILE'
  (
     DEFINE SCHEMA schema_name
     DESCRIPTION 'define SCHEMA'
   (
       var1 VARCHAR (50)
   );

   STEP setup_tables
   (
      APPLY
       ('RELEASE MLOAD database_name.table_name;')
     TO OPERATOR (DDL_OPERATOR() );

   );
);

Output Code:

OUT -> Teradata_01.py

Recommendations

• For this issue, you can type the insert statement manually, and/or since the DML statement is not being supported yet, ask the SnowConvert team to add support for that specific case.
