The parameters make the stored procedure more useful and reusable. IN is the default mode. When you define an IN parameter in a stored procedure, the calling program has to pass an argument to the stored procedure. In addition, the value of an IN parameter is protected.

It means that even you change the value of the IN parameter inside the stored procedure, its original value is unchanged after the stored procedure ends. In other words, the stored procedure only works on the copy of the IN parameter. The value of an OUT parameter can be changed inside the stored procedure and its new value is passed back to the calling program.

Notice that the stored procedure cannot access the initial value of the OUT parameter when it starts. It means that the calling program may pass the argument, and the stored procedure can modify the INOUT parameter, and pass the new value back to the calling program. The following example creates a stored procedure that finds all offices that locate in a country specified by the input parameter countryName :.

A procedure is called a recursive stored procedure when it calls itself. Most database systems support recursive stored procedures. But, it is not supported well in MySQL. The following syntax is used for creating a stored procedure in MySQL.

It can return one or more value through parameters or sometimes may not return at all. By default, a procedure is associated with our current database. See the complete syntax:. It is the default mode. It takes a parameter as input, such as an attribute. When we define it, the calling program has to pass an argument to the stored procedure. This parameter's value is always protected.

It is used to pass a parameter as output. Its value can be changed inside the stored procedure, and the changed new value is passed back to the calling program. It is noted that a procedure cannot access the OUT parameter's initial value when it starts.

It means the calling program can pass the argument, and the procedure can modify the INOUT parameter, and then passes the new value back to the calling program. We can use the CALL statement to call a stored procedure. The following syntax is used to call the stored procedure in MySQL:.

Let us understand how to create a procedure in MySQL through example. First, we need to select a database that will store the newly created procedure. We can select the database using the below statement:. Suppose we want to display all records of this table whose marks are greater than 70 and count all the table rows.

In this procedure, we have used the IN parameter as 'var1 ' of integer type to accept a number from users. Its body part fetches the records from the table using a SELECT statement and returns only those rows that will be supplied by the user. It also returns the total number of rows of the specified table. See the procedure code:. In this procedure, we have used the OUT parameter as the 'highestmark' of integer type.

Its body part fetches the maximum marks from the table using a MAX function. When we call the procedure, the OUT parameter tells the database systems that its value goes out from the procedures. Its body part first fetches the marks from the table with the specified id and then stores it into the same variable var1. When we have several procedures in the MySQL server, it is very important to list all procedures. It is because sometimes the procedure names are the same in many databases.

In that case, this query is very useful. We can list all procedure stored on the current MySQL server as follows:. This statement displays all stored procedure names, including their characteristics. In case we want to list stored procedures with a specific word, we need to use the LIKE clause. We can list all stored procedure in the MySQL mystudentsb database using the below statement:.

It will give the below output where we can see that the mystudentdb database contains four stored procedures :. MySQL also allows a command to drop the procedure. When the procedure is dropped, it is removed from the database server also. The following statement is used to drop a stored procedure in MySQL:.

We can do this by first selecting the database and then use the syntax as follows to remove the procedure:. See the below output:. We first launch the tool and log in with the username and password to create procedures in the MySQL Workbench. Now, we need to do the following steps for creating a stored procedure:.

Go to the Navigation tab and click on the Schema menu where all the previously created databases available. Select your desired database for example, employeedb. It will pop up the following options. Right-click on the Stored Procedure , and we will get the default procedure code. See the below screen:. Complete the procedure code and click on the Apply button.

In the next window, we will review the procedure code once again, and if no error was found, click on the Apply button. After clicking on the Apply button, click on the Finish button for completion. We can navigate to the schema menu again to verify this newly created procedure. It means first select your database and expand it to display its sub-menu. In the sub-menu , expanding the stored procedure option will show the newly created procedure. See the below image:. We can call the procedure by tapping on the red rectangle box or simply execute the CALL statement.

However, it provides a command that is used to change the characteristics of a stored procedure. This command may alter more than one change in the procedure but does not modify the stored procedure's parameters or body.

The below statement is used to change the characteristics of a procedure but not the actual procedure :.
