Object Conversion Summary

This section shows the object conversion Summary

Identified Objects

The count of all the top-level DDL objects (Table, View, Procedure, etc.) that the SnowConvert identified. If there were a parsing error on an object that made it unreconcilable, it wouldn't be an identified object.

CSV Associated field name

• TotalIdentifiedObjects

Sample

Input

IN -> Teradata_01.sql

-- Statement without parsing error
CREATE TABLE table1(
     column1 INT,
     column2 INT 
);

-- Statements with parsing error
CREATE TABLE table2(
     column1 INT,
     column2 INT INT
);

CRATE TABLE table3(
     column1 INT
);

Output

OUT -> Teradata_01.sql

-- Statement without parsing error
CREATE OR REPLACE TABLE table1 (
     column1 INT,
     column2 INT
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"teradata"}}'
;

-- Statements with parsing error
CREATE OR REPLACE TABLE table2 (
     column1 INT
--                ,
-- ** SSC-EWI-0001 - UNRECOGNIZED TOKEN ON LINE '10' COLUMN '6' OF THE SOURCE CODE STARTING AT 'column2'. EXPECTED 'Column Definition' GRAMMAR. LAST MATCHING TOKEN WAS 'INT' ON LINE '10' COLUMN '14'. CODE '15'. **
--     column2 INT INT
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"teradata"}}'
;

-- ** SSC-EWI-0001 - UNRECOGNIZED TOKEN ON LINE '13' COLUMN '1' OF THE SOURCE CODE STARTING AT 'CRATE'. EXPECTED 'STATEMENT' GRAMMAR. LAST MATCHING TOKEN WAS 'CRATE' ON LINE '13' COLUMN '1'. CODE '81'. **
--CRATE TABLE table3(
--     column1 INT
--)
 ;

Expected Identified Objects: 2

Explanation: The table1 presented doesn't have a parsing error; the table2 even though it has a parsing error, the parser is still capable of recognizing the object as a table, so both are counted as an identified object; the table3 has a parsing error that makes it unreconcilable for the parser and, as a consequence, is not counted as an identified object.

Object Conversion Rate

The percentage of fully converted objects among the objects identified

Formula

(identify_objects_converted_succesfully / total_identify_objects) * 100
