Re: Navicat MySQL GUI for Linux version 8.0.23 is released.
Hmm. Speaking of Navicat, does anybody out there have an easy way to scrub the control coding from scripts developed under Navicat? I expect that they're there mostly for coloration on displays, but it's kind of obnoxious when you want to do anything else with them. -- Barry -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Search for column value in a string variable?
Hi. . .I'm trying to be lazy and write a query where I stuff a list of names into a variable (@namelist), and then try to find items in column lastname which appear anywhere in that list. It doesn't want to work, and even regexp isn't working, though that's probably my fault. Any suggestions? I'm completely open to various possibilities of delimiters in the namelist. Obviously this would let me reuse the query over and over, just changing the one line. -- Barry -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: Determining number of vowels in a string
I'd rather do it in a sql statement rather than using a scripting language.

The last line of the license notice reads: Contact MySQL AB if you need clarification of these terms or if you need to ask about alternative arrangements. This kind of suggests to me that they're willing to talk. I expect that as long as you're willing to pay *something*, there's probably a lot of room for negotiation. It's distinctly not in their interest to eliminate collateral development efforts. And there are already several products out there which do connect with MySQL and cost $100.

I suppose I could revert back to the old PW mgt scheme but that may weaken the security. There was an earlier post on this list which discussed new vs old password management. The gist is, that the configuration switch controls how *future* passwords are constructed. So, you can switch to old passwords, configure 1 userid for Fabforce with any privileges you choose, and switch to new passwords again. None of your existing arrangements are disturbed, but you can now use the single old-style userid to connect with DBD4, and keep your production users as secure as possible. I've just done this on Win XP, and it works very nicely.

How to query on part of a date column?
I've got a table of people who registered for a convention. Each person
has a registration date, kept in a standard date field. How do I select
for people who registered in a particular month or year? The obvious tests
like:
Select * from Capclave2005reg
Where Year('Date Paid') = 2004;
return no rows. I can extract any piece of that date I want in a SELECT,
but can't seem to use it in a WHERE clause at all. There has to be
something really obvious that I'm missing?
