CREATE OR REPLACE FUNCTION "CategoryBulkImport"("CategoryType")  RETURNS                TABLE (
        "CATEGORY_NODE_ID" text,                                  "PARENT_ID" text,
"CODE"text,                                  "DESCRIPTION" text,                                  "SEQUENCE_NUMBER"
integer,                                 "ACCOUNT_GROUP_ID" integer,
"FINANCIALREPORT_CATEGORY_ID"integer,                                  "FINANCIALREPORT_DETAIL_ID" integer
        )  AS  $BODY$
 
                SELECT $1.*;
