Parameters

filterExpression  String
Filter SQL expression for restriction as a composite format string - does not include WHERE. When escaping is needed for field names, use standard ANSI quotes.
parameters  Object
Restriction parameter values.
Remarks

Each indexed parameter, e.g., "{0}", in the composite format filterExpression will be converted into query parameters where each of the corresponding values in the parameters collection will be applied as IDbDataParameter values to an executed IDbCommand query.

If needed, field names that are escaped with standard ANSI quotes in the filter expression will be updated to reflect what is defined in the user model.
