Code Conversion - Sybase IQ Functional Differences

Note

Conversion Scope

For Sybase IQ, the assessment and translation capabilities primarily focus on TABLES, VIEWS, STORED PROCEDURES, and FUNCTIONS. While other types of ANSI-standard statements are recognized, they are not yet fully supported for conversion. The tool may identify them, but will not perform a complete translation for these unsupported code units.

SSC-FDM-SY0001

Calling stored procedure in FROM might have compilation errors

Description

Snowflake supports calling a stored procedure in the FROM clause when the procedure meets certain conditions otherwise the query fails.

Code Example

Input Code:
Sybase
 SELECT * FROM MyProcedure(1, 'test');
Generated Code:
Snowflake
 SELECT
  *
FROM
  --** SSC-FDM-SY0001 - CALLING STORED PROCEDURE IN FROM CLAUSE MIGHT HAVE COMPILATION ERRORS **
  TABLE(MyProcedure(1, 'test'));

SSC-FDM-SY0002

Calling stored procedure in FROM might have compilation errors

Description

Snowflake does not contain indexes for query optimization.

Code Example

Input Code:
Sybase
 SELECT * FROM TABLE1 FORCE INDEX (MyIndex);
Generated Code:
Snowflake
 SELECT
  *
FROM
  TABLE1
--         --** SSC-FDM-SY0002 - FORCE INDEX IS NOT SUPPORTED IN SNOWFLAKE **
--         FORCE INDEX(MyIndex)
                             ;
