SqlCommand.CommandType Property

 

Gets or sets a value indicating how the CommandText property is to be interpreted.

Namespace:   System.Data.SqlClient
Assembly:  System.Data (in System.Data.dll)

Public Overrides Property CommandType As CommandType

Property Value

Type: System.Data.CommandType

One of the CommandType values. The default is Text.

Exception Condition
ArgumentException

The value was not a valid CommandType.

When you set the CommandType property to StoredProcedure, you should set the CommandText property to the name of the stored procedure. The command executes this stored procedure when you call one of the Execute methods.

The Microsoft .NET Framework Data Provider for SQL Server does not support the question mark (?) placeholder for passing parameters to a SQL Statement or a stored procedure called with a CommandType of Text. In this case, named parameters must be used. For example:

SELECT * FROM Customers WHERE CustomerID = @CustomerID

For more information, see Configuring Parameters and Parameter Data Types.

The following example creates a SqlCommand and sets some of its properties.

Public Sub CreateSqlCommand()
    Dim command As New SqlCommand()
    command.CommandTimeout = 15
    command.CommandType = CommandType.Text
End Sub
