Remarks

Use the ExecuteQuery method to query data stores for resulting sets. You can visualize resulting sets using the XPDataView. Refer to this article for additional information: How to: Access Data in SQL Query Results.

Use QueryParameterCollection to pass strongly-typed parameters. See examples here: Always Encrypted (SQL Server only).

Note

The ExecuteQuery method sends statements directly, so the correct statement syntax and parameter names format depends on a particular database server.
