How to return a result set from oracle procedure

oracle-11g-r2selectstored-procedures

How can i return a result set from a stored procedure in oracle ?
suppose i want to return a table from a simple select statement such as this :

Select * from tblTest

I tried this but this seems plain wrong!

CREATE OR REPLACE 
PROCEDURE ProcSelectEveryThing(cursor_ OUT TYPES.REF_CURSOR)
AS

BEGIN

OPEN cursor_ FOR
      SELECT * FROM "tblTest"; 
END;

what is wrong?

You don't need a return statement, because it is using OPEN and FOR... It is the same like RETURN...

The error is in the name of the table, you put it in "" double quotes. Remove that, use simply the name of the table, and use the type SYS_REFCURSOR like this:

CREATE OR REPLACE 
PROCEDURE ProcSelectEveryThing(cursor_ OUT SYS_REFCURSOR)
AS

BEGIN

OPEN cursor_ FOR
      SELECT * FROM tblTest; 
END;

How to return a CTE as REFCURSOR from an Oracle stored procedure

Since the CTE is part of the same SQL statement, it should not contain a semicolon.

So, there should be no semicolon on the second line of the third block or the third line of the fourth block. The fifth block does not have a contiguous SQL statement.

Mysql – How does MySQL return a result set from a stored procedure

Each SELECT statement that does not insert into a table or a variable will produce a result set.

If you want your stored procedure to return only one result set, make sure that you only have one SELECT statement. If you have other SELECT statements, make sure that they insert results into a table or variable.

UPDATE
Here are examples of stored procedures.

This stored procedure would return one result set:

DELIMITER ;;
CREATE DEFINER=CURRENT_USER PROCEDURE stored_procedure_name()
BEGIN
    DECLARE local_variable_name INT;

    SELECT column_name FROM table_1 LIMIT 1 INTO local_variable_name;

    SELECT * FROM table_1;
END;;
DELIMITER ;

This stored procedure would return two result sets:

DELIMITER ;;
CREATE DEFINER=CURRENT_USER PROCEDURE stored_procedure_name()
BEGIN
    DECLARE local_variable_name INT;

    SELECT column_name FROM table_1 LIMIT 1 INTO local_variable_name;

    SELECT * FROM table_1;

    SELECT * FROM table_2;
END;;
DELIMITER ;
