SnowConvert AI - Object Conversion Summary¶

The Object Conversion Summary section of the assessment report for Sql

Identified Objects¶

The count of all the top-level DDL objects (such as Table, View, and Procedure) that the SnowConvert AI identified. If an object has a parsing error that makes it unreconcilable, it would not be identified.

CSV Associated field name¶

TotalIdentifiedObjects

Sample¶

-- 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
);

-- 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_successfully / total_identify_objects) * 100

CSV Associated field name¶

ObjectConversionRate

Sample¶

CREATE TABLE table1(
     column1 INT,
     column2 INT
);

CREATE VIEW view1 AS
SELECT orderkey
FROM orders;

CREATE TABLE table2(
     COLNAME VARCHAR(20)
)
ON COMMIT PRESERVE ROWS;

CREATE OR REPLACE TABLE table1 (
     column1 INT,
     column2 INT
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"teradata"}}'
;

--** SSC-FDM-0007 - MISSING DEPENDENT OBJECT "orders" **
CREATE OR REPLACE VIEW view1
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"teradata"}}'
AS
SELECT
     orderkey
FROM
     orders;

CREATE TABLE OR REPLACE table2 (
COLNAME VARCHAR(20)
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"teradata"}}'
;

Expected Object Conversion Rate: 66.66%

Explanation: In this example we have 3 statements, all of them have been identified as an object, but just the table1, and the view1 have a 100% conversion rate. The table3 has an error warning meaning that the conversion of this table is not 100%, that’s why just 2 of the 3 statements are counted as fully converted objects.

Fully Converted Objects¶

The number of identify objects that were converted successfully, meaning this objects have a 100% conversion rate.

CSV Associated field name¶

ObjectsSuccessfullyConverted

Sample¶

CREATE TABLE table1(
     column1 INT,
     column2 INT
);

CREATE VIEW view1 AS
SELECT orderkey
FROM orders;

CREATE TABLE table2(
     COLNAME VARCHAR(20)
)
ON COMMIT PRESERVE ROWS;

CREATE OR REPLACE TABLE table1 (
     column1 INT,
     column2 INT
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"teradata"}}'
;

CREATE OR REPLACE VIEW view1
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"teradata"}}'
AS
SELECT
     orderkey
FROM
     orders;

CREATE OR REPLACE TABLE table2 (
COLNAME VARCHAR(20)
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"teradata"}}'
;

Expected Fully Converted Objects: 2

Unrecognized Elements¶

Represents any code element (or parts of them) such as DML, DDL, control statements, with parsing errors that SnowConvert AI was unable to process.

CSV Associated field name¶

UnrecognizedElements

Sample¶

CREATE TABLE table1(
     column1 INT,
     column2 INT
);

CREATE VIEWW view1 AS
SELECT orderkey
FROM orders;

CREATE OR REPLACE TABLE table1 (
     column1 INT,
     column2 INT
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"teradata"}}'
;

-- ** SSC-EWI-0001 - UNRECOGNIZED TOKEN ON LINE '6' COLUMN '1' OF THE SOURCE CODE STARTING AT 'CREATE'. EXPECTED 'STATEMENT' GRAMMAR. LAST MATCHING TOKEN WAS 'CREATE' ON LINE '6' COLUMN '1'. CODE '81'. **
--CREATE VIEWW view1 AS
--SELECT orderkey
--FROM orders;

Expected Unrecognized Elements: 1

Explanation: In this example we have 2 statements, the table1 is successfully identified as an object, in the other hand the view1, has a parsing error that means it’s impossible to identify the view as an object, because of this SnowConvert AI reports 1 Unrecognized object.

Lines of Code in Unrecognized Elements¶

Represents the number of lines in unrecognized elements.

CSV Associated field name¶

UnrecognizedElementsLOC

Sample¶

CREATE TABLE table1(
     column1 INT,
     column2 INT
);

CREATE VIEWW view1 AS
SELECT orderkey
FROM orders;

CREATE OR REPLACE TABLE table1 (
     column1 INT,
     column2 INT
)
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"teradata"}}'
;

-- ** SSC-EWI-0001 - UNRECOGNIZED TOKEN ON LINE '6' COLUMN '1' OF THE SOURCE CODE STARTING AT 'CREATE'. EXPECTED 'STATEMENT' GRAMMAR. LAST MATCHING TOKEN WAS 'CREATE' ON LINE '6' COLUMN '1'. CODE '81'. **
--CREATE VIEWW view1 AS
--SELECT orderkey
--FROM orders;

Expected Lines of Code in Unrecognized Elements: 3

Explanation: The element view1 is an unrecognized element, this means that the lines related to this elements are counted as Lines of Code in Unrecognized Elements.

Wrapped Objects¶

Represent the number of wrapped objects present in source input code

Note

This field applies only to Oracle reports.

Expected Lines of Code in Unrecognized Elements: 1

Explanation: The procedure is declared as a wrapped object, that’s why is counted as a wrapped object.
