Hello,

What syntax provider do your use? I recommend to use MSAccessSyntaxProvider for OLE DB & MS Jet connection to Excel.

Hi:

I use c# code information:

GenericSyntaxProvider syntaxProviderGeneric = new GenericSyntaxProvider();

queryBuilder.SyntaxProvider = syntaxProviderGeneric;
queryBuilder.MetadataProvider = new OLEDBMetadataProvider { Connection = connection };

So I must to use MSAccessSyntaxProvider for OLE DB & MS Jet ?

Yes. We developed special syntax providers for different SQL engines that support different SQL syntax and metadata extraction rules. It's a good idea to use them rather than uncertain generic syntax. MS Jet is a common SQL engine that is used to work with MS Access, Excel and Text/CSV files. MSAccessSyntaxProvider suits for all of these data sources.
