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.*;

$BODY$
LANGUAGE sql VOLATILE
COST 100;
