Executes a SQL SELECT statement with the specified command behavior and returns the result set.

Syntax

Visual Basic
Public Function ExecuteReader( _
   ByVal cmdBehavior As CommandBehavior _
) As ULDataReader

C#
public ULDataReader ExecuteReader(
   CommandBehavior cmdBehavior
);

Parameters

Return value

The result set as a ULDataReader object.

Remarks

The statement is the current ULCommand object, with the ULCommand.CommandText and any ULCommand.Parameters as required. The ULDataReader object is a read-only result set. For editable result sets, use ULCommand.ExecuteResultSet(CommandBehavior), ULCommand.ExecuteTable(CommandBehavior), or a ULDataAdapter.

If the ULCommand.CommandType is System.Data.CommandType.TableDirect, ExecuteReader performs an ULCommand.ExecuteTable(CommandBehavior) and returns a ULTable downcast as a ULDataReader.

SELECT statements are marked as read-only by default for performance reasons. If the query is going to be used to make updates, the statement must end with " FOR UPDATE".

This is the strongly-typed version of System.Data.IDbCommand.ExecuteReader(System.Data.CommandBehavior) and System.Data.Common.DbCommand.ExecuteReader(System.Data.CommandBehavior).
