SQL 7 datetime stored procedure parameter


I'm having a problem passing a datetime parameter to an SQL 7 stored procedure.  I get an ODBC error - "Error converting datatype varchar to datetime".  The string is "01/01/2000 00:23:28.578"

I tried passing it as a string '2000.01.01 00:23:28.578' and using CAST ... AS DATETIME without luck too.  Tested the CAST and INSERT in Query Analyzer and they looked fine.

Delphi help, manual and D5 Developer's guide were no help.

-- Delphi 5 Code --

StoredProc1.Params[0].AsDateTime :=
      StrToDateTime(spDate+' '+sTime);
StoredProc1.Params[1].AsString :=
      sServer;
StoredProc1.Prepare;
StoredProc1.ExecProc;

-- SQL 7 Stored Procedure --

CREATE PROCEDURE [usp_InsertStat]
      @itime datetime,
      @server varchar(15)
AS
INSERT INTO stats (itime, server) VALUES (
      @itime,
      @server)

Can anyone help me out?

Thanks,

Scott

Well, sounds like a problem with ODBC... but :

check StoredProc1.Params with the object inspector and set datetime to the param-type of param 0. (just in case is not).

Are you tried to pass only the date without time ?

(StoredProc1.Params[0].AsDate :=  StrToDate(spDate);

if works in this way, it will help to see where is the problem.

However, Why just donĀ“t pass the param as string and then in the stored procedure you do the job of the conversion to datetime. As I see, you anyway do this conversion with the DateToStr function in Delphi.

I ran into the same problem a while back and ended up running the entire thing through DTS , making the conversion in VBScript during the transformation.  


Good luck!!

NetoMan -
I was planning to try your suggestion on my home computer (Win2000), unfortunately SQL Server is saying it is corrupted and I will need to reinstall.
I brought my work computer (notebook) home tonight, so I'll try soon.

DrDelphi -
I'm using a memorystream to rip through a large number of multi-megabyte, variable length records.  A fair bit of logic and manipulation needs to take place.  DTS may be able to handle it, but I don't think as quickly. ?

I have the program using dynamic SQL Insert statements, but I want to try stored procedures to compare speed.  Besides, I should know how.<g>

You forced me to take a closer look at how Params was indexed.  Looking at the Params in Object inspector I found that [0] in SQL 7 is a 'RETURN_VALUE'.

I switched to .ParamByName('@itime').AsDateTime and everything works well now.

Thanks,
