Re: Inserts so slow using _Connection.Execute

Actually my timer was wrong. the actual inserts are taking about 1 min.50
secs for the whole record set. This can not be the best that is possible.

Hi Steve,

I've never had to insert 50,000 records, so I can't speak to the time
factor. But I'm not sure if you are saying it takes 30 seconds per
inserted record, or 30 seconds for the entire 50,000? If it's taking 30
seconds to insert 50,000 records, that doesn't seem like it's too far off.

However, another approach might be to do something like:

// Get the source 50,000 records
Select *
From SourceDB..SourceTable
Where <SomeCondition>

// work on the records and save them back.

// Move them into the targe table
Insert Into OtherDB..TargetTable
Select * SourceDB..SourceTable
Where <SomeCondition>

This assumes that the same user name and password can be used to access
both DB's.

Can any one help here? I have the following job to do - which works but
sooo slow.
D7 - SQL 2K to different databases on 2 different servers.
I connect to the first server / database using _Recordset and _Connection
and pull back 50000 records in about .5 sec. This is fine. I then need to
do some work on this record set and then insert these records into a
different database on a different server. I use another _Connection to do
the following
While Not FromRecordSet.EOf do
begin
// process the records

end
Instr := 'Insert ['+tablename+'] values (' + stemp + ')';
ToConnection.Execute(Instr,recs,-1)
FromRecordSet.MoveNext
end;// While not eof
The insert takes about 30 seconds to do this with 50000 records. This is
way to slow. I could get the same performance using TTAbles. I want this
application to be a console app when it's finished so don't need any
fancy gui stuff.

any help would be appreciated.
regards
steve
