To merge multiple queries into a single stored procedure in MySQL, follow the below steps:
Here is an example of a stored procedure that merges two queries:
CREATE PROCEDURE mergeQueries(IN p_name VARCHAR(50), IN p_value INT)
BEGIN
DECLARE v_id INT;
SELECT id INTO v_id FROM table1 WHERE name = p_name;
UPDATE table2 SET value = p_value WHERE id = v_id;
END;
In this example, the procedure takes two parameters, pname and pvalue. The first query retrieves the ID from the table1 where the name is equal to the provided parameter. The second query updates the value in table2 for the retrieved ID.
Note that the queries are separated by semicolons, and the procedure is enclosed within BEGIN and END statements.
