Provdes a description of the results of the query and its effect on the database.

The query may return multiple result sets. Execution of the query may effect the database state. sets no flags, so calling is functionally equivalent to calling .

The query returns a single result set. Execution of the query may effect the database state.

The query returns column information only and does not effect the database state.

The query returns column and primary key information. The query is executed without any locking on the selected rows. When using KeyInfo[cref, System.Data.CommandBehavior], the SQL Server .NET Data Provider appends a FOR BROWSE clause to the statement being executed. The user should be aware of potential side effects, such as interference with the use of SET FMTONLY ON statements. See SQL Server Books Online for more information.

The query is expected to return a single row. Execution of the query may effect the database state. Some .NET data providers may, but are not required to, use this information to optimize the performance of the command. When you specify with the method of the object, the OLE DB .NET Data Provider performs binding using the OLE DB interface if it is available. Otherwise, it uses the interface. If your SQL statement is expected to return only a single row, specifying can also improve application performance. It is possible to specify when executing queries that return multiple result sets. In that case, multiple result sets are still returned, but each result set has a single row.

Provides a way for the to handle rows that contain columns with large binary values. Rather than loading the entire row, enables the to load data as a stream. You can then use the or method to specify a byte location to start the read operation, and a limited buffer size for the data being returned. When you specify , you are not required to read from the columns in the order they are returned. However, once you have read past a location in the returned stream of data, data at or before that location can no longer be read from the .

When the command is executed, the associated object is closed when the associated object is closed.

Specifies how a command string is interpreted.

A SQL text command.

The name of a stored procedure.

When the property is set to , the property should be set to the name of the table or tables to be accessed. The user may be required to use escape character syntax or include qualifying characters if any of the tables named contain any special characters. All rows and columns of the named table or tables will be returned when you call one of the Execute methods. In order to access multiple tables, use a comma delimited list, without spaces or padding, containing the names of the tables to access. When the CommandText property names multiple tables, a join of the specified tables is returned
