Can't drop database that shows up in show databases
SHOW DATABASES; shows that I have a database called test, but when I call DROP DATABASE test, I get ERROR 1008 (HY000): Can't drop database 'test'; database doesn't exist When I run any queries on that database, I get errors like: mysql select * from Users; ERROR 1017 (HY000): Can't find file: './test/Users.frm' (errno: 13) My previous solution of deleting the ./test folder worked only temporarily, but restarting mysqld seemed to recreate it.

Re: Can't drop database that shows up in show databases
Waynn- does the OS user you use to execute mysql have create/write/read/execute rights to the ./test folder?

Re: Can't drop database that shows up in show databases
Waynn: What user are you using to execute mysql from the command line? Perhaps run mysql (from command line) as root then execute the desired actions (such as drop). This will make sure you can drop the table and avoid any further problems.

Re: Can't drop database that shows up in show databases
This problem actually started after I moved the datadir to another folder, so that's quite possible. We stopped everything, rsynced the folders over, then restarted mysql. But I do notice a permissions problem, since the owner currently is root. I'll chown it to mysql then see what happens. I'll post back with results.

Regular Expressions in MySQL -- how to show addresses that have the same numbers?
Hi All, We've got a database (legacy, running MySQL 4.1.22 Standard) of constituents. We want to search through it for duplicates, and I've found that a good way to generate a list of potential duplicate addresses is to look for addresses that have matching street numbers, zipcodes, and last names. For instance, consider the following two records: John Smith, 123 E Easy St, Springfield, IL 12345 John Smith, 123 East Easy Street, Springfield, IL 12345 They're not a letter for letter match, but if you just compare the last names (smith), and the numeric components of the address (123 and 12345), they would match. I am wondering, is there a way to search through a table like this (all fields are varchar): fname, lname, address, city, state, zip Using regular expressions, to show any records which match another record on lastname, street number, and zip? I could do this easily enough in a client language like PHP, C#, Java, etc., but I was hoping I could do it in SQL directly. Is this possible? If it's possible, but only with MySQL 5 or better, I could probably export the database, and import it into a newer version of MySQL. But it would naturally be nicest if we can do on the existing server.

Re: Comma's in data?
Use \ to escape.
mysql insert into table1 values ('algo\,otra');
Query OK, 1 row affected (0.00 sec)
mysql select * from table1;
+---+
| a |
+---+
| algo |
| algo,otra |
+---+
2 rows in set (0.00 sec)

I have a client that wants to insert data into a VarChar field that contains

Example:

How can I allow this?

As an aside, I'm curious why the parser doesn't understand that the
comma is part of the string in this context? It's already between two
single quotes ... ? Shouldn't that be enough?

I've never had to escape commas; only special characters, eg: '_%.
MySQL seems to ignore escaping if the following character is not
special, though:
[EMAIL PROTECTED] create table test (t1 varchar(255));
Query OK, 0 rows affected (0.03 sec)
[EMAIL PROTECTED] insert into test values ('qwert'),
('qwe,rt'),('qwe\,rt');
Query OK, 3 rows affected (0.00 sec)
Records: 3 Duplicates: 0 Warnings: 0
[EMAIL PROTECTED] select * from test;
++
| t1 |
++
| qwert |
| qwe,rt |
| qwe,rt |
++
3 rows in set (0.00 sec)
Are you getting an error when you insert a row? If so, what is the
error? Perhaps you are having a character set issue. This is what
mine looks like:
[EMAIL PROTECTED] show variables like 'character\_set\_%';
+--++
| Variable_name| Value |
+--++
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_results| latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
+--++
6 rows in set (0.00 sec)

mysqldump on specific columns only?
I'm trying to dump all the columns of a table but one in a restructuring of my schema. I found this post: http://www.jsw4.net/info/listserv_archives/mysql/05-wk49/msg00131.html which seems to indicate that this isn't possible, but I was wondering if anyone had any suggestions. My current solution is to do a simple search and replace, but that won't work for everything. I could always do regex search/replace, as well, but I'm hoping for something native to mysqldump, since the files are going to be rather big.
