RE: Primary Keys Duplicate Values
U might want to use this query select field1 from yourtable group by field1 having count(*) 1 this would result all the duplicate row. If u want to list down all the duplicate records select * from yourtable where field1 in (select field1 from yourtable group by field1 having count(*) 1) good luck -Original Message- From: Andy Ousterhout [mailto:[EMAIL PROTECTED]] Sent: Monday, October 07, 2002 10:24 AM To: CF-Talk Subject: RE: Primary Keys Duplicate Values If all of your current fields have meaning, I recommend that you add a new field that is a meaningless number that you use as your key field. I've found that if I use a field with meaning as my key that I end up wanting to change that value. Exceptions might be code tables like ZIP Code and State Abbreviations where you have a reasonable expectation that the key (zip code or abbreviation) will never change.

I have a table with 18000 records. There are three fields say field1, field2 and field3. There are no primary keys at the moment. I want to delegate field1 as the primary key in the modified table. When I try to create field1 as the primary key, an error is generated as there are duplicate values in the records in field1. How do I find which values are duplicate in field1. I cannot use the Find and replace function as I do not know which values to look for. Also manually it is impossible as there are too many records to search through. Is there a Cold Fusion custom tag or function or SQL syntax I can use? Any help will be much appreciated.

Can I just confirm what you guys are saying: In CFMX named locks should be used in place of scoped locks and locks are only needed When a possible race condition could occur?

Pre-MX. Sure, the scope of a NAME-based lock will be tighter than using SCOPE, but SCOPE will be safer and, as a bonus, you can use CF 5's (and prior) auto-checking for missing locks... Which is no longer available in MX because it is no longer needed. Basically, NAME is older than SCOPE, and SCOPE was added to address issues that NAME cannot handle. SCOPE was added to resolve bugs in earlier releases of CF around the shared scope memory corruption problems. That is no longer an issue in CFMX.

RE: CFQUERY and STARTROW=0 (??!)
The CF query start row starts with 1 not 0 -Original Message- From: Tom Sammons [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 01, 2002 5:09 PM To: CF-Talk Subject: CFQUERY and STARTROW=0 (??!) Hi all, I was looking up some stuff on joins versus unions, and came across an opinion that used CFQUERY as an example. (I won't post the url since I don't know if it's kosher here.) However, under this person's tutorial topic called Limiting Results it used this code: CFQUERY DATASOURCE = Friends Name = Query1 Maxrows = 10 Startrow = 0 followed by the comment: Note that the starting row is set at 0. Remember that computers start numbering at 0, not 1. So the first record in the database is record number 0. --- Now, I understand offsets, et cetera, but I've never heard it used regarding cfquery (or any other sql query for that matter -- I couldn't even find another mention of startrow=0 anywhere in google or altavista for any major sql platform...). And obviously, I've never had a problem with using startrow=1 missing the first record of a query return set. Has anyone else ever used startrow=0 in *any* sql platform, is it practical/standardized, or is this guy just telling people to do things the way he thinks they should be? Inquiring minds (at least one) want to know...
