![]() ![]() If we want to delete the stored procedure, then we can simply drop it using the following syntax: ![]() Executing the above calling statement gives the following output: The above call to the stored procedure will return the list of all the label numbers whose last transaction was done on the 1 st of December of the 2012 year. The syntax of calling or executing the stored procedure is shown below: The above call to the stored procedure will return the list of all the label numbers whose last transaction was done on the 1st of December of the 2012 year. In our above example, we can call the GetLabelsOfLastTransDate stored procedure simply by using the following call statement – The syntax of calling or executing the stored procedure is shown below –ĬALL name_of_SP (value of parameters accepted by stored procedure) Our stored procedure will be as follows:ĬREATE PROCEDURE GetLabelsOfLastTransDate(IN last_trans_date DATE)ĭELIMITER Calling the Stored Procedure in MySQL Now, we will create a stored procedure that will return the label numbers whose last transaction date is passed as the parameter to the GetLabelsOfLastTransDate procedure. Hence 30 rows are present in the last_tran_date table. Let us confirm all the inserted values using the SELECT query: `LabelNo` int(11) NOT NULL DEFAULT '0' COMMENT 'Generated Label No',Īnd add some of the values using INSERT statement like the following: `itemCode` int(11) NOT NULL COMMENT 'ItemCode From Item Master', ![]() MYSQL STORED PROCEDURE CODELet us create one simple stored procedure, but before that, I will create a sample table named last_tran_date that will store the date of the last transaction on the particular object along with its item code and label number using the following query: Example to Implement MySQL Stored Procedureīelow are the examples of MySQL Stored Procedure:ġ. Calls to other stored procedures can also be included in this part of the stored procedure. Execution part of the stored procedure: We can write our program or code in this section of stored procedure that can contain conditional, looping statements, initializing and assigning the value of variables, and preparing and executing the database queries. Declaration part of the stored procedure: We can declare the local variables if we want any in this part of the stored procedure.ĥ. BEGIN and END: BEGIN keyword marks the beginning of the stored procedure while END marks the completion of the stored procedure in MYSQL.Ĥ. IN OUT: These types of parameters are assigned the values while calling the stored procedure, and the value can be modified or overwritten inside the stored procedure as well as referenced and used by the stored procedure.ģ.OUT: These are the parameters that can be assigned the values and overridden in the stored procedure but cannot be referenced by it.IN: These types of parameters are assigned the values while calling the stored procedure, and the value cannot be modified or overwritten inside the stored procedure but only referenced and used by the stored procedure.These parameters can belong to either of the three types: Take the following stored procedure definition: GetCustomerList varchar(50)Īnd consider the PHP code needed to build the SQL statement that will execute this procedure from some page submission: $sql = "EXEC GetCustomerList. Where is stored procedure stored in database?įirst, your PHP code is often nearly as messy as if you were dynamically building SQL statements for execution.How do you call a stored procedure in SQL server?.How can I call stored procedure in PHP?. ![]()
