How to manipulate Date Fields of MSSQL server

Question

I build a database link from my oracle Database to an sql Server , i can run any select statement that i want with no problem but when i try to run the above :
select empl."emp_id", "emp_code", "emp_first", "emp_last" ,
"empio_dtin", "empio_dtout", "section_id",
to_date ( "empio_dtin" , 'dd/mm/yyyy hh24:mi:ss')
from "dbo.employees"@ATERMON empl INNER join "dbo.empio"@atermon empio on empl."emp_id" = empio."emp_id"
where "empio_dtin" > '05/01/09'
order by "section_id", "emp_code"
i took the message :
ORA-02070: database ATERMON does not support TO_DATE in this context
The problem is the time because when i run the select statement the date fields brings as value only the dates values for example "01/05/09" without the time value that i need most,
i try to insert the values into an oracle table with Date format fields but i take only the dates values again.

Answer 1

Is the empio_dtin field defined with a date datatype or a character datatype?? If the field is a date, try using TO_CHAR instead of TO_DATE:
to_char ("empio_dtin" , 'dd/mm/yyyy hh24:mi:ss')
Assuming that empio_dtin is defined as a date datatype, you might want to try directly converting the string '05/01/09' to a date rather than letting Oracle impliciting covert the string to a date.
"empio_dtin" > to_date('05/01/2009', 'MM/DD/YYYY')
