Delete
Hello, I just checked the list for answer to this question and looks like there hasn't been one. I have a similar problem, I want to delete a record from a table where the value of the field is equal to the value of a field in another table. delete from table1 where table1.column = table2.column; Any thoughts?

Searching records ?'s
Hi Everyone, I'm writing a script using perl for a search function. I have a large text column that I want to scan for certain words. I do something like the following: select * from table_name where column_1 LIKE %word1% AND column_1 LIKE %word2%; In this situation, words like 'tree' will return 'streets'. How can I find exact matches while still scanning the entire record? Are there any MySQL REGEX's that might help out. I'm considering indexing the entire column and compare my query against it but wanted to see if there were any other solutions out there. Thanks!

LIKE
Hi Everyone, Does this make sense: select * from table_name where column_1 LIKE %word1% OR %word2%; yeilds 1 record but... select * from table_name where column_1 LIKE %word2% OR %word1%; yields 0 records. I'm scanning a VARCHAR column trying to return records that contain or word1 and word2. Same thing occurs when I replace OR with AND. The search words appear appear in the column as: word1 followed by word2. Am I using the LIKE incorrectly? Does MySQL have to match the first LIKE operator before the second?

Perl-MySql DBD Errors
Hello, I have redhat 7.0 with Mysql Ver 8.8 Distrib 3.23.22-beta. This was the Mysql version that came on the redhat cd's. Perl and the Perl DBI are installed and working correctly. MySql seems to be working correctly as well(i.e. no problems with permissions, created db's, tables, etc). However, I can't install the mysql::DBD...I grabbed this from the Mysql site, Msql-Mysql-modules-1.2215.tar. For the life of me I can't find the mysql.h file that it keeps asking for? Any ideas where this is...is it a bug with this version. Thanks in advance!

Please Help. What am I doing wrong? Do I need to do an un-install before trying to re-install DBD? Should I blow out Perl altogether and reinstall? Has anyone seen this before?
