I have database hr has table Employee this table has field EmployeeName
when i write in query analyzer :
select ^ from Employee where EmployeeName='احمد'
not give me any result
but when i write
select * from Employee where EmployeeName=N'احمد'
it give me result
meaning it support arabic
but i have stored procedure not accept arabic and i dont know how to handel it to accept search by EmployeeName
CREATE Procedure sp_EmployeeSelect
Declare @SQLQuery as nvarchar(2000)
SET @SQLQuery ='SELECT * from Employee Where (1=1)'
If @EmployeeName <>''
Set @SQLQuery = @SQLQuery + ' AND (EmployeeName LIKE ''%'+@EmployeeName +'%'') '
what is the proplem in this stored procedure and how to solve it
It's a bad idea to do so, and should be fixed. The time you are saving is a culture-specific format, it is a text, something the computer does not calculate with.
A DateTime in a computer is a floating point. The integer-part counts the days passed since the epoch (start of counting of days, often 1/1/1900), the decimal part represents the time, in ticks. They are not two separate facts - and should be modelled as a single field, of the DateTime-datatype. The computer can easily calculate with those.
Breaking the date and time into separate fields is as usefull as using a separate field for the day, month, year, hour, minute and second. If they represent a single atomic fact, than that is how it should be modelled.

If you can't read my code, try converting it here[^]
It's interesting that the Date type in Oracle while handled as a single entity but is stored internally as seven bytes. One byte each for year, month, day, hour minute, second and fraction of a second.
It's a space waster, but oh so fast to calculate with.
Timestamp on the other hand is stored as a floating point to save space.
You could try and merge DATE_CREATED and TIME_CREATED to get a DATETIME value then you could use between.
Something like (most likely will not work as written):
(Date_Created + Time_Created) BETWEEN @startdatetime AND @enddatetime
Just throw the exception.
There is no reason, I can think of, that you should need to catch an exception from a stored procedure.
Throwing the exception will allow the developer to have an error message and pursue fixing the error.
