INTO out_ProdName, out_CustName, out_price We have created a stored procedure named getProductPrice in the database as shown below − Now, we will insert 5 records in Sales table using INSERT statements − Let us create another table with name Sales in MySQL database using CREATE statement as follows − Since this procedure doesn’t accept arguments you can call this procedure by omitting the parameters as shown below −Įxample: Calling a stored procedure that returns a value While calling a stored procedure that doesn’t accepts any arguments, we can omit the parenthesis as shown below −Īssume we have created another procedure with name getData that retries the contents of the table EMP − Once you call the procedure by passing the required values you can verify the contents of the Emp table as shown below −Įxample: Calling a stored procedure without parameters Mysql> CALL InsertData ('Rahman', 55000, 'Hyderabad') Mysql> CALL InsertData ('Raman', 45000, 'Vishakhapatnam') Mysql> CALL InsertData ('Raju', 35000, 'Bangalore') INSERT INTO Emp(Name, Salary, Location) VALUES (name, sal, loc) įollowing statement calls the above created stored procedure Mysql> CREATE TABLE Emp (Name VARCHAR(255), Salary INT, Location VARCHAR(255)) Īssume we have created a stored procedure InsertData which accepts the name, salary and location values and inserts them as a record into the above create (Emp) table. Suppose we have created a table named Emp in the database using the CREATE statement and inserted three records in it as shown below − Example: Calling a stored procedure with parameters are the list of parameters accepted by the procedure (if it accepts any). Where procedure_name is the name of an existing procedure you need to call and param1 and param2…. Syntaxįollowing is the syntax of the CALL statement in MySQL −ĬALL procedure_name(parameter) The call statement of MySQL is used to invoke/call a stored procedure. They may return result sets in case you use SELECT statements they can return multiple result-sets. These procedures contain IN and OUT parameters, or both.

Before we proceed, create a sample table and insert few records in it. Let us explore a few examples of the Case statement in SQL. In the following example, we want to get Product name for ProductID 4.it does not satisfy Case statement condition therefore, it gave output from Else expression. Similarly, if we change the condition in a Case statement in SQL, it returns appropriate expression. Once a condition is satisfied, its corresponding value is returned. In Case statement, we defined conditions. Look at the following example We declared a variable and specified value 1 for it. You want to get Productname for a particular ProductID. Suppose you have a table that stores the ProductID for all products in a mini-store. In this article, we would explore the CASE statement and its various use cases. It can be used in the Insert statement as well. We can use a Case statement in select queries along with Where, Order By, and Group By clause. The case statement in SQL returns a value on a specified condition.
