SSC-EWI-0052

Unusable object

Severity

Medium

Description

This error happens when the source code uses a parameter or variable that is not supported or was not recognized by the conversion tool.

Example code

Input Code (Oracle):

IN -> Oracle_01.sql

-- Additional Params: -t JavaScript
CREATE OR REPLACE PROCEDURE PROCEDURE_PARAMETERS(PARAM SDO_GEOMETRY)
AS
    VARIABLE SDO_GEOMETRY;
BEGIN
    VARIABLE := PARAM;
END;

Output Code:

OUT -> Oracle_01.sql

CREATE OR REPLACE PROCEDURE PROCEDURE_PARAMETERS (PARAM GEOMETRY)
RETURNS STRING
