To run the procedure, copy and paste the following example into a new query window and click Execute. Notice that different methods of specifying the parameter values are shown.

In the subsequent executions of the stored procedure, SQL Server reuses the plan so that the stored procedure can execute very fast with reliable performance.
Now we know the basics of stored procedure, let's check how to create them, we will start from the basic example of it. We have seend above how we can create stored procedure using GUI of SQl server management studio, but if you want to create stored procedure using T-SQL query, here is the steps:.
Now, once we have stored procedure ready, we will have to call it using C code, and it can be called as shown below. You just need to pass the table name as an input parameter to the procedure and you will get the whole information about the table and its columns. You can execute this procedure as:. You can also create your own custom information to get only some specific information about the columns of a table.
We will use this view to retrieve the list of columns of a table. We will create a stored procedure and use this logic inside the stored procedure. In this section, you will learn about dynamic SQL queries.
We use the dynamic queries when we want to specify a value for checking against a condition, but the value is not static i. Dynamically means that the value will be defined at the run time instead of compile time.
We have created the following example of a stored procedure that will search the items in a table on the basis of input parameters provided to it. We have used dynamic queries to search for the data in the table. You can observe in the above example that we could manipulate the Where condition dynamically, based on our requirements. Thus, you might have understood how you can use a dynamic Where clause in a stored procedure.
In this section, you will see an example of a stored procedure that will return a concatenated result of two columns of a Select statement. You will see how you can concatenate the results of a Select statement.
Thus, you might have learned how you can concatenate the results of different columns of a Select statement resultset. In this section, you will see an example of a stored procedure that will print all the integers from 1 to Printing all the numbers manually is obviously not a good approach. The following SQL code will create the stored procedure:. As a result, the numbers from 1 to are printed on the output screen.
Hence, you might have learned how you can use a While loop and in which type of scenarios it should be used. We will create an example of a stored procedure in which we will create a directory in the local file system where the SQL Server instance is running. We use this stored procedure to run commands in the Windows command line. To create a folder, pass the command to create a folder to this stored procedure as the parameter:. The following stored procedure will get the current name of the server:.
You can add, remove or rename the members of a database role. We will create a stored procedure that will rename a member name of a database role.
We have created a member named TestRole for a database role named dbo. To return the most recent records from a table in SQL Server, you need a column that stores unique values in a sequence. For example, it can be an ID column or an Identity column, or a column that stores timestamp when the record is inserted. Recording the timestamps at the time of record insertion is the best idea among all the above methods.
You can perform a lot of operations and get a lot of information. For example, you can find the records inserted on a particular date or time. You can easily find the last inserted record if you have created a timestamp column.
However, in this section, we will see how we can find the last inserted record of a table having an identity column.
We will create a stored procedure to find the last inserted record from a table. Tip: If you do not have a unique column, you can alter the table and create an identity column, but only if the size of the table is small.
