Mysql – Recursive Query in MySQL using stored proceedure and CURSOR

The MSDN/BOL topic for DECLARE CURSOR contains example syntax for cursor usage. That said, as I had 5 minutes to spare on the train this morning...

-- Create temporary table for Business Units (replace with the "real" table)
DECLARE @BusinessUnit TABLE (BU NVARCHAR(MAX))

INSERT @BusinessUnit
SELECT 'India' UNION SELECT 'International' UNION SELECT 'US' UNION SELECT 'UK'

DECLARE @K TABLE (BU NVARCHAR(MAX),K NVARCHAR(MAX),Y MONEY,A MONEY,D MONEY,YP MONEY)
DECLARE @FY INT
DECLARE @BU NVARCHAR(MAX)

SET @FY = 2012

DECLARE BU_cursor CURSOR FAST_FORWARD FOR
SELECT BU FROM @BusinessUnit

OPEN BU_cursor
FETCH NEXT FROM BU_cursor INTO @BU

WHILE @@FETCH_STATUS = 0
BEGIN
    INSERT @K (BU, K, Y, A, D, YP)
    EXEC dbo.SP_Report @FY, @BU

    FETCH NEXT FROM BU_cursor INTO @BU
END

CLOSE BU_cursor
DEALLOCATE BU_cursor

SELECT * FROM @K

Try tagging all local variables with something like my_

CALL import_members();

In the book MySQL Stored Procedure Programming, all cursor examples give the local variable a unique name from its corresponding table column (if you have the book, see page 108 Example 5-15).

Sidenote : Where are weekly_com and monthly_com coming from ???
