Mac OS X Binary libmysqlclient.a problem
I installed 3.23.27 for Mac OS X from the binaries. When installing PHP, I ran into problems with duplicate symbol names between libmysqlclient.a and System.framework. I also got a similar error building DBD::mysql. In both cases, the duplicate symbols were strto* functions. I built PHP with built-in mysql support to resolve it. When I built DBD::mysql and the problem came up again, I decided to try fixing it. I removed strto.o from libmysqlclient.a (along with a few other modules that ranlib complained were empty) and it built properly, tested successfully and seems to work properly. Is this a problem with the binary distribution, or am I missing something?

Re: mysqldump question

I used this last time: mysqldump -h mysql.io.com -u DB1 -p --opt DB1 ! backup-file.sql mysql -h mysql.io.com -u DB2 -p DB2 backup-file.sql But it copies the whole shebang (all tables in DB1). The situation I have now is that I use DB2 (after previously using DB1 up to two weeks ago), but this afternoon, I dropped one of the tables by accident. Call it Table1. Table1 is now filled with current entries, but is missing all its old entries, which can be found in the copy of Table1 in DB1. I would like to *add* (not replace) all the entries in Table1 of DB1 to Table1 of DB1. I'm guessing this would involve using mysql dump to get the copy of Table1 out of DB1 and then into DB2 under a new name, and then use some command within mysql's command line interface to add the rows from the old table to the current one? Some kind of Merge function? If they're on the same server, try: insert into DB2.table1 select * from DB1.table1 Otherwise, consider selecting INTO OUTFILE on DB1 and then using mysqlimport or LOAD INFILE to bring it in to DB2.

Supply the root password and you should be in. If you don't specify -p on the command line, it assumes you are attempting to gain access without a password, and your security isn't set up to allow this. This is a bit confusing at first...

Re: can create, cannot drop...?

Can't drop tables
I just installed mysql 3.23 and then ran a script to create a database I had previously been using in an older version. I have a couple questions. First, how can I make a drop database statement not fail if the database doesn't exist. A book I was using seemed to say: drop database dbname if exists; Would work, but I get an error with this. What is the correct syntax? Second, on this newest installation, I can't drop a database. I get the error "failed to rmdir ./dbname, errno 21" or something similar. If I su to my mysql user, and cd to the data directory, an rmdir dbname works successfully, so I'm not sure why this is failing. The actual data files in the database are all gone after the drop statement. Only the empty directory sticks around. Any help would be appreciated.

In order to get it working, I'd have to build 3.23 and I had trouble with that when I first tried, but I'm sure I could get it working with a little effort... First of all - realize that fulltext search, as implemented in mysql, is WEIRD. If you intend to use it as searchengine and expect it to behave like modern searchengines do (google, altavista) then think again, it does not. (You want boolean search for that, or perhaps ranked boolean search, but not something like mysql has now. - 'coming soon' to a mysql version near you.) I have evaluated it (see my post, use archives) for searchengine use and found that it didn't suit my needs. (since it will have a very weird order of sorting, and by that I mean that a document with two of the words in the query can rank below (!) one with just one of the querywords - depending on what mysql thinks is the information-value of the word.) As for stability - It has had its share of bugs, but I think most are fixed. FULLTEXT indexes are about 95% of the size of the table, and they can perform quite well or very slow, depending on what you do. I did notice in the explanation of the FULLTEXT indexing/searching scheme that the weight of a word decreased as it became more common in the search pool, which might be problematic for me. These are resumes of "tech industry" people and often a client will search for "HTML" or "C++". Some things like that would appear in the text of _many_ resumes. At and rate, it's probably worth playing with. I don't need boolean search capability (the users in this case probably can't spell boolean, let alone understand a boolean search query...) A completely different possibility is to keep the resume and cover letter text in individual files somewhere (perhaps named by candidate id) and use some other tool to index and search them. If I did this, I would still need to coordinate the search with mysql. For instance, they would want to be able to limit the search to a certain state, or a certain date range (date of submission)...has anybody done anything like this? Since these tools rank things by relevance, and limit the quantity of results, I think I would need to limit the search set with a mysql query _before_ doing the full text search... I saw one recommendation to use HTDig, or something like that. I could also use the Apple Information Access Toolkit, as this in on Mac OS X. Any feedback on either of these? Also, I don't consider disk usage an issue at all. As long as performance is good, they can put as much disk space as needed in to it.
