Question
MYSQL Stored Procedures
Hi Guys,
I need to create stored procedure on mysql.
Basically I have 2 tables in MySql the structure are identical, I need to take data from table 1 if it exists in table 2 then update if it does not exist then insert. We are using SKU as the auto increment
CREATE DEFINER=`root`@`localhost`
BEGIN
If exists (select table1.cost from table1, table2 where table1.sku=table2.sku) then
UPDATE table2 SET table2.cost= table1.cost WHERE table2 sku.id= table1.sku;
else
INTO table2 (cost) VALUES(table1.cost);
end if;
END
I know my example is very poor, but I have never really used Stored procedures. Thanks Guys for your help!

Everything between BEGIN and END needs to be a valid SQL statement or part of the flow control (IF/ELSE, etc.) operators. This probably does what you are looking for:
CREATE DEFINER=`root`@`localhost`
BEGIN
UPDATE table2, table1 SET table2.cost= table1.cost WHERE table2 sku= table1.sku;
iNSERT INTO table2 (sku, cost) SELECT table1.sku, table1.cost FROM table1 LEFT JOIN table2 ON (table1.sku = table2.sku)
WHERE table2.sku IS NULL;
end if;
END
