SalesTable record via QueryService

Hi,

I am attempting to retrieve a SalesOrder record in the SalesTable via the QueryService.

I am able to use ExecuteStaticQuery to return all the rows in the table via the SalesTableSelect query in AOT, but I cannot retrieve a single row using ExecuteQuery method.

Here is my C# code so far:

QueryServiceClient qsc = new QueryServiceClient();

Paging paging = null;

QueryMetadata query = new QueryMetadata();

QueryDataSourceMetadata salesOrderDataSource = new QueryDataSourceMetadata();

DataSet result;

query.Name = "SalesTableQuery";

query.DataSources = new QueryDataSourceMetadata[1];

salesOrderDataSource.Name = "SalesTable DataSource";

salesOrderDataSource.Enabled = true;

salesOrderDataSource.Table = "SalesTable";

salesOrderDataSource.DynamicFieldList = true;

salesOrderDataSource.DynamicFieldListSpecified = true;

query.DataSources[0] = salesOrderDataSource;

query.DataSources[0].Ranges = new QueryRangeMetadata[1];

QueryDataRangeMetadata range = new QueryDataRangeMetadata();

range.FieldName = "SalesId";

range.TableName = "SalesTable";

range.Enabled = true;

range.Value = mySalesId;

query.DataSources[0].Ranges[0] = range; 

result = qsc.ExecuteQuery(query, ref paging);

Error:  Cannot find table 0

I know the SalesTable exists and I know the record with my SalesId exists.

Thank you for your help.
