I have a stored procedure that has an output parameter which is a cursor
Here's the code for the stored procedure I currently use, I don't know how to get the return value
def kf_fpy
sql.call("{call calfpy(?,?,?,?,?)}",[workcenter,product,stattime,endtime,Sql.resultSet(OracleTypes.CURSOR)])
{
cursorResults ->
cursorResults.eachRow() {
x ->
kf_fpy = x.getAt('kf_fpy')//ERROR OCCURED
}
}
And I got an error "Method threw 'java.lang.NullPointerException' exception. Cannot evaluate $Proxy11.toString()"
Stored Procedure:
PROCEDURE CALFPY(workcenter in varchar2,produ in varchar2,stdt in varchar2,etdt in varchar2,p_out out pkg_package.type_cursor)
PKG_PACKAGE:
create or replace
package pkg_package
as
type type_cursor is ref cursor;
type type_record is record
(
kf_ws varchar2(20),
kf_fpy number,
kf_tfpy number,
kf_pro varchar2(200)
);
end;
Check out this solution :
Procedure :
create or replace procedure GRAILS_EXAMPLE
(
v_name IN VARCHAR2,
ref_cur1 IN OUT SYS_REFCURSOR
)
AS
begin
OPEN ref_cur1 FOR
SELECT UPPER(v_name) AS UPPER_NAME
FROM DUAL;
end GRAILS_EXAMPLE;
Controller which calls procedure :
String upperName;
sql.call("BEGIN GRAILS_EXAMPLE(?,?); END;",
[params.name, Sql.resultSet(OracleTypes.CURSOR)]) {cursorResults ->
if (cursorResults.next()) {
upperName = cursorResults.getAt('UPPER_NAME');
}
}
If you need to get at a field that isn't properly aliased in your proc you can still access it by its index. For example the follow would also work in the above controller:
upperName = cursorResults.getAt(0)
