Conversion failed because the data value overflowed
Conversion failed because the data value overflowed
(OP)
Hi all,
I use sql server 2005 with a linked server to Pervasive.
Using ODBC Pervasive version 10.
My Problem is that there is a date field in Pervasive that can contain the value 00/00/0000.
When I run and open query sql runs ok until it hots one of these dates.The I get the error "Conversion failed because the data value overflowed the data type used by the provider."
I know this is because SQL is saying what the hell is this 00/00/0000?
But I need all these columns returned..
The only way so far that I can get all columns back is by using convert to varchar but this takes along time to run..
Any other ideas?
eg:Below takes 8Mins to run but I get 00-00-0000 returned.
Need to speed things up
SELECT *
FROM OPENQUERY(cellular, 'SELECT refnumber,Convert(InWorkShopDate, SQL_VARCHAR)as InWorkShopDate,FROM JOBSE ')

RE: Conversion failed because the data value overflowed
In your slow query, how many records are you returning? How many do you need? Have you tried running the query (SELECT refnumber,Convert(InWorkShopDate, SQL_VARCHAR)as InWorkShopDate,FROM JOBSE ) in the PCC to see how slow/fast it is there?
Have you tried PSQL v10.10 (latest update)? I believe there was a fix for "legacy" null dates. I don't know if it'll help in your case.
