Property Value

String

The SQL statement or stored procedure to execute. The default value is an empty string ("").

Implements

CommandText

Examples

The following example creates an OracleCommand and sets some of its properties.

public void CreateOracleCommand()
{
   OracleCommand command = new OracleCommand();
   command.CommandText = "SELECT * FROM Emp ORDER BY EmpNo";
   command.CommandType = CommandType.Text;
}

Public Sub CreateOracleCommand()
    Dim command As New OracleCommand()
    command.CommandText = "SELECT * FROM Emp ORDER BY EmpNo"
    command.CommandType = CommandType.Text
End Sub

Remarks

When the CommandType property is set to StoredProcedure, the CommandText property should be set to the name of the stored procedure. The user may be required to use escape character syntax if the stored procedure name contains any special characters. The command executes this stored procedure when you call one of the Execute methods.

The .NET Framework Data Provider for Oracle does not support the question mark (?) placeholder for passing parameters to an SQL statement called by an OracleCommand of CommandType.Text. In this case, named parameters must be used. For example:

SELECT * FROM Customers WHERE CustomerID = :pCustomerID

When using named parameters in an SQL statement called by an OracleCommand of CommandType.Text, you must precede the parameter name with a colon (:). However, in a stored procedure, or when referring to a named parameter elsewhere in your code (for example, when adding OracleParameter objects to the Parameters property), do not precede the named parameter with a colon (:). The .NET Framework Data Provider for Oracle supplies the colon automatically.
