To invoke stored procedures, you can use the CALL statement or other stored procedures. The first time a stored procedure is invoked, MySQL looks it up in the database catalog, compiles the code, places it in the cache memory , and executes it. Subsequent runs in the same session execute stored procedures from the cache memory, making them extremely useful for repetitive tasks. Stored procedures make use of parameters to pass values and customize results.

Parameters are used to specify the columns in a table in which the query operates and returns results. After the procedure name, use parenthesis to specify the parameters to use in the procedure, the name of the parameter, the data type, and data length. Separate each parameter with a comma. The wizard is intuitive and simplifies the process since you do not have to place delimiters or worry about the format. Step 4: Confirm execution by clicking Apply and create the procedure by clicking Finish.

Step 5: Execute the procedure to see if it works. Create a new SQL tab for executing queries. To get a list of all stored procedures you have access to, including their characteristics, use the following syntax:. The statement displays the names and characteristics of stored procedures that you have access to on the server.

The LIKE argument finds stored procedures containing a specific word in their name. Follow these steps to see stored procedures:. Step 1 : Double-click the database you want to use in the Navigator section. To alter a stored procedure means to change the characteristics of a procedure.

MySQL Workbench drops the existing stored procedure and creates a new one after the changes have been made. Step 1: In the Navigator section, right-click the stored procedure you want to modify.

Select the Alter Stored procedure… item. Step 2: When the tab opens, make the desired changes to the existing stored procedure and click Apply. Step 3: An SQL Script review window appears showing the process — dropping the existing stored procedure and creating a new one containing the changes. Click Apply and then Finish in the next window to execute the script. Step 1: Expand the Stored Procedures item in the Navigator section.

Right-click the stored procedure you want to delete and choose Drop Stored Procedure… in the context menu. Step 2: In the confirmation window, click Drop Now to delete the stored procedure.

Stored procedures help reduce the network traffic between applications and MySQL Server by keeping all the programming logic on the server. Click on Apply. A dialog box, Apply script to database opens.

On the Review the script screen, you can view the code of the stored procedure. When we declare an IN type parameter, the application must pass an argument to the stored procedure. It is a default mode. When we declare the INOUT type parameter, the application has to pass an argument, and based on the input argument; the procedure returns the output to the application.

When we create a stored procedure, the parameters must be specified within the parenthesis. The syntax is following:. Suppose we want to get the list of films based on the rating. Suppose we want to get the count of the films that have a PG rating. To store the value returned by the procedure, pass a session variable named PGRatingMovies. Suppose we want to get the total count of movies based on the rating. It contains the list of the stored procedure and stored functions created on the database.

Because instead of sending multiple lengthy SQL statements, applications have to send only the name and parameters of stored procedures. Always stored procedure is faster than general query. Reasons for using stored procedures : Reduce network traffic -- you have to send the SQL statement across the network.

With sprocs, you can execute SQL in batches, which is also more efficient. Second, specify a list of comma-separated parameters for the stored procedure in parentheses after the procedure name. Advantages : A Stored Procedure can be used as a modular programming which means create once, store and call for several times whenever it is required.

This supports faster execution. It also reduces network traffic and provides better security to the data. By doing this, you can reuse the same stored procedure in several triggers.
