View SourceParameters
- 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.
Return Value
Int32Record count for the modeled table for the specified parameters.
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 any of the specified parameters reference a table field that is modeled with
either an EncryptDataAttribute or FieldDataTypeAttribute, then the function
GetInterpretedFieldValue(String, Object) will need to be called, replacing the target parameter with the
returned value so that the field value will be properly set prior to executing the database function.
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.
This is a convenience call to QueryRecordCount(RecordRestriction).
