ADO.NET in a Nutshell

Name

OleDbSchemaGuid

Synopsis

The OleDbSchemaGuid class is used to specify the type of schema table used by the OleDbConnection.GetOleDbSchemaTable( ) method. This class is used to indicate the information you want to retrieve. For example, you can retrieve the tables in a database using code like this:

DataTable dt = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[  ]

    {null, null, null, "TABLE"});

After executing this code, the System.Data.DataTable object dt will contain a list of all tables in the current database. You can also retrieve information such as a list of views, stored procedures, constraints, keys, indexes, and so on by using a different OleDbSchemaGuid. Note that when you use a System.Data.DataSet, you can use the OleDbDataAdapter.FillSchema( ) method to retrieve some of the required schema information.
