hi, i have one problem with udfs
when they take TIMESTAMP as argument.


for example udf returns an integer.
Everything is perfect till i do something like this in C++Builder


Query->SQL->Clear();
Query->SQL->Add("SELECT * FROM T WHERE UDF(:dd) = TABLE.ID");
Query->Prepare(); //Here is thrown exception
Query->ParamByName("dd")->AsDateTime = Date();
Query->Open();


Exception is "Unknown data type SQL error code = -804"
