RE: Unusual SQL error
Sounds to me like when SQL created it's execution plan it is running several parts of the query simultaneously. For some reason when this happens it causes a conflict within your query. What SQL is asking you to do is give it a hint about how to process the query to avoid this problem. __ Bill Grover Supervisor MIS Phone: 301.424.3300 x3324 EU Services, Inc.

RE: Unusual SQL error
Bill, This just got me thinking about a problem I had a while back. I had a sql7 query like this: select * from myTable where isDate(myDateField) = 1 and month(myDateField) 2 Everything worked fine until I moved to SQL 2000. Then it would return an error because myDateField could not be converted to datetime. The myDateField column can have a date, NR, INC. (Not my choice, doing this was dictated to us by another group in our company). The explanation I got from another DBA said that SQL server 7 processed each item of the where sequentially, but SQL 2000 processes all of the where items at the same time. If that is true, do you think that setting the maxdop 1 would prevent the error? No rush for an answer, we already changed all of our code, this is more just for my own piece of mind.

RE: Unusual SQL error
Maybe but not necessarily. It is possible that SQL thinks the most efficient way to retrieve the data is to process the 2nd part of the where before the 1st part. If you have data in your fields that are not dates then your select will fail because of this data. MAXDOP goes beyond just the where clauses. If you are joining tables together SQL will actually do selects on each individual table simultaneously then link the results together before doing the final filtering. The MAXDOP setting controls how many of these selects will take place simultaneously. I hope that answered your question. __ Bill Grover Supervisor MIS Phone: 301.424.3300 x3324 EU Services, Inc.
