   CommandType commandType
): DataTable;

Parameters

connection
Represents an open connection to a SQL Server database.
commandText
The text of the query.
commandType
Specifies how a command string is interpreted.

Return Value

A representation of one table of in-memory data.

Remarks

Use the ExecuteDataTable method to retrieve a System.Data.DataTable from a database. This requires less code than using the SqlDataAdapter.Fill method, performing the operations necessary to generate the table of in-memory data returned by a SqlDataAdapter.

Example

[C#, Visual Basic] The following example creates a SqlDataAdapter and then executes it using the Fill method. The example is passed a string that is a Transact-SQL statement that returns an aggregate result.

[C#]
SqlConnection connection = new SqlConnection("Server=127.0.0.1;Database=Northwind;Uid=sa;Pwd=;");

DataTable customers = DatabaseUtility.ExecuteDataTable(connection, "SELECT * FROM Customers", CommandType.Text);
[Visual Basic]
Dim connection As New SqlConnection("Server=127.0.0.1;Database=Northwind;Uid=sa;Pwd=;")

Dim customers As DataTable = DatabaseUtility.ExecuteDataTable(connection, "SELECT * FROM Customers", CommandType.Text)
