I assume I need to create a dataset to do this. Is there anyway of using SQL just to return the column names without any data?

Try this SQL: select Name from syscolumns where id=Object_id('TableName')

Hi Ian,

Try this:
oleDbConnection1.Open();

DataTable schemaTable =
oleDbConnection1.GetOleDbSchemaTable(OleDbSchemaGuid.Columns,

new object[] {null, null, "YourTableName"});

oleDbConnection1.Close();

All the data is stored into schemaTable.

You didn't identify the type of database you are using but I've posted an example using VB.NET:

Sub ListTableSchema()

Dim DatabaseConnection As New System.Data.OleDb.OleDbConnection
Dim SchemaTable As DataTable

DatabaseConnection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=E:\My Documents\db1.mdb"

DatabaseConnection.Open()

'Retrieve schema information about Table1 Columns.
SchemaTable =
DatabaseConnection.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Columns, _
New Object() {Nothing, Nothing, "Table1"})

Dim RowCount As Int32
For RowCount = 0 To SchemaTable.Rows.Count - 1
Console.WriteLine(SchemaTable.Rows(RowCount)!COLUMN_NAME.ToString)
Next RowCount

DataGrid1.DataSource = SchemaTable

DatabaseConnection.Close()

End Sub
