This is like the bug from hell. It is kind of hard to explain, so
please bear with me.
Background Info: SQL Server 7.0, on an NT box, Active Server pages
with Javascript, using ADO objects.
I'm inserting simple records into a table. But one insert command is
placing 2 or 3 records into the table. The 'extra' records, have the
same data as the previous insert incident, (except for the timestamp).
Here is an example. Follow the values of the 'Search String' field:
I inserted one record at a time, in the following order (And only one
insert per item):
airplane
jet
dog
cat
mouse
tiger
After this, I should have had 6 records in the table. But, I ended
up with 11!
Here is what was recorded in the database:
Vid DateTime Type ProductName SearchString NumResults
cgcgGeorgeWeb3 Fri Sep 26 09:48:26 PDT 2003 i null airplane 112
cgcgGeorgeWeb3 Fri Sep 26 09:49:37 PDT 2003 i null jet 52
cgcgGeorgeWeb3 Fri Sep 26 09:50:00 PDT 2003 i null dog 49
cgcgGeorgeWeb3 Fri Sep 26 09:50:00 PDT 2003 i null jet 52
cgcgGeorgeWeb3 Fri Sep 26 09:50:00 PDT 2003 i null jet 52
cgcgGeorgeWeb3 Fri Sep 26 09:50:22 PDT 2003 i null dog 49
cgcgGeorgeWeb3 Fri Sep 26 09:50:22 PDT 2003 i null cat 75
cgcgGeorgeWeb3 Fri Sep 26 09:52:53 PDT 2003 i null mouse 64
cgcgGeorgeWeb3 Fri Sep 26 09:53:06 PDT 2003 i null tiger 14
cgcgGeorgeWeb3 Fri Sep 26 09:53:06 PDT 2003 i null mouse 64
cgcgGeorgeWeb3 Fri Sep 26 09:53:06 PDT 2003 i null mouse 64
Look at the timestamps, and notice which ones are the same.
I did one insert for 'dog' , but notice how 2 'jet' records were
inserted
at the same time. Then, when I inserted the 'cat' record, another
'dog' record was inserted. I waited awhile, and inserted mouse, and
only the mouse was inserted. But soon after, I inserted 'tiger', and 2
more mouse records were inserted.
If I wait awhile between inserts, then no extra records are inserted.
( Notice 'airplane', and the first 'mouse' entries. ) But if I insert
records right after one another, then the second record insertion also
inserts a record with data from the 1st insertion.
Here is the complete function, in Javascript (The main code of
interest
may start at the Query = "INSERT ... statement):
----------------------------------------------------------------------
//Write SearchTrack Record ------------------------------------
Search.prototype.writeSearchTrackRec = function(){
Response.Write ("<br>Calling function writeSearchTrack \n"); // for
debug
var Query;
var vid;
var type = "i"; // Type is image
var Q = "', '";
var datetime = "GETDATE()";
//Get the Vid
// First - try to get from the outVid var of Cookieinc
try{
vid = outVid;
}catch(e){
vid = Request.Cookies("CGIVid"); // Gets cookie id value
vid = ""+vid;
if (vid == 'undefined' || vid == ""){
vid = "ImageSearchNoVid";
}
}
try{
Query = "INSERT SearchTrack (Vid, Type, SearchString, DateTime,
NumResults) ";
Query += "VALUES ('"+vid+Q+type+Q+this.searchString+"',
"+datetime+","+this.numResults+ ")";
this.cmd.CommandText = Query;
this.cmd.Execute();
}catch(e){
writeGenericErrLog("Insert SearchTrack failed", "Vid: "+vid+"
- SearchString:: "+this.searchString+" - NumResults: "+this.numResults
, e.description);
}
}//end
-----------------------------------------------------------------
I also wrote a non-object oriented function, and created the command
object inside the function. But I had the same results.
I know that the function is not getting called multiple times
because I print out a message each time it is called.
This really stumps me. I'll really appreciate any help you can
offer.
Thanks,
George
