SqlCommand.CommandType Property

Definition

Namespace:

System.Data.SqlClient

Assembly:

System.Data.SqlClient.dll

Package:

System.Data.SqlClient v4.9.0

Source:

System.Data.SqlClient.notsupported.cs

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

C#

public override System.Data.CommandType CommandType { get; set; }

Property Value

CommandType

One of the CommandType values. The default is Text.

Exceptions

ArgumentException

The value was not a valid CommandType.

Examples

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

C#

public void CreateSqlCommand()
{
   SqlCommand command = new SqlCommand();
   command.CommandTimeout = 15;
   command.CommandType = CommandType.Text;
}

Remarks

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
