How to Execute Stored Procedures in C#?

Perform storage procedures in the C#program

In database operations, specific tasks need to be performed through storage procedures. This article will explore how to perform storage procedures in the C#program.

Perform storage procedures in C#

Storage procedure is a pre -compiled SQL statement, which provides a convenient way to encapsulate complex database operations. To perform the storage procedure from the C#program, follow the steps below:

<.> 1. Create a database connection:

Use the SQLConnection object to establish a database connection, specify the database server, database and user credentials. <.> 2. Create command objects:

Create a SQLCOMMAND object and set its CommandType property to StoredProcedure. This means that the command will execute the storage procedure.

<.> 3. Specify the storage procedure name:

Set the CommandText property of the SQLCOMMAND object to the name of the storage procedure to be executed, including any necessary mode limited character.

<.> 4. Execute the storage procedure:

Use the ExecutenOnQuery method of the SQLCOMMAND object to perform the storage procedure. This method will execute the storage procedure and will not return any results.

<.> 5. Processing return value (optional):

If the storage procedure returns the value, add parameters to the SQLCOMMAND object and specify its direction (for example, parameterdirection.output). After the storage procedure is performed, the return value is retrieved from the OUT parameter.

Code example:

The following code fragment demonstrates how to perform a storage procedure called "ProcedureName", which does not accept any input parameters:

Common error investigation:

If you encounter an abnormal "you can't find the storage procedure dbo.test", you may need to provide the correct mode name in the Commandtext property of the SQLCommand object. In addition, before trying the storage procedure, make sure the storage procedure has been created and existed in the database.
