<sjrussel> !m sjrussel insert_id() <SQL> sjrussel: Nothing found <sjrussel> !m sjrussel insert <SQL> sjrussel: (INSERT Syntax) : http://dev.mysql.com/doc/mysql/en/INSERT.html <will> !man last insert id <SQL> (How to Get the Unique ID for the Last Inserted Row) : http://dev.mysql.com/doc/mysql/en/Getting_unique_ID.html <sjrussel> thx <_chris> does anyone know how to select * from a table but add a DATE_FORMAT at the same time? <will> Add a DATE_FORMAT? <will> !tell us about evil <SQL> will asked me to tell you this: Evil is clearly defined at http://www.parseerror.com/sql/select*isevil.html <jp-> i've got just a test db setup i'm toying with, i have a primary key that autoincrements, how can i use this to modify that data or do i need to delete that row and insert a new one with the new data? <jp-> update, that's what i was looking for. <dalvenjia> got a code here http://www.phpriot.com/2607 to insert multiple users and p***words to mysql db. can someone please check it and tell me if it will work Im afraid to mess up my db <Supaplex> when in doubt, create a backup. <Cyde> Eeekkk, I need some rather urgent help, just lost a drive in a RAID array and I really need to backup all of my MySQL databases and transfer them to another computer. How do I do this? (Linux, latest version of MySQL) <sol> hey - is there any function to do something like concat() multiple rows in a table? <sol> for example... <sol> select concat(job.name, ', ') from employee left join job on employee.id=job.employeeid; <sol> to say, comma separate a chunk of all jobs for a particular employee <litheum> !m sol group by functions <SQL> sol: (GROUP BY (Aggregate) Functions) : http://dev.mysql.com/doc/mysql/en/GROUP-BY-Functions.html <litheum> sol: group_concat <sol> thank you <sol> you'd figure there'd be a link from the concat article :/ <sol> this makes things easy :) <sol> i figured id get a "you can't" <litheum> yeah it's a nifty function for sure <litheum> sol: if you think there should be a link from the concat docs, you should file a docs feature request at bugs.mysql.com... i think it'd be a good idea, too <Jax> evening my friends <sol> yea, I'll do that right away then thanks :) -- these links should definitely be there. They're easy to find on google if you know what you're looking for, but these obscure ones are impossible to find sometimes. <cold_> hmm after u creat a udf, how do you call it ? <Jax> CALL <Jax> oh wait <Jax> http://dev.mysql.com/doc/refman/5.0/en/adding-udf.html <Jax> maybe you should read the whole section.. if you are really sure UDFs are what yo uwant <Jax> i'm really drunk. perhaps you can also just ignore me :D <dPL> Hey guys. I'm trying to figure out if it is possible to accomplish the following task in one mysql-query: given a table which links a varying number of items n to a specific (where n can be 0), select the last 5 months before a given month m and the 5 after m which contain at least one item n <Punkcut> does anyone know where I can find a list and descriptions of all the possible variables I can put into my.cnf for Mysql 4.1? <mishehu> I'm setting up a schema for a database that we're goign to be using with odbc. I'm designing the table in mysql, so since I want transaction support, after every table I'm using the Engine=InnoDB. But since it's an odbc app, somebody might want to use it with another rdbms. how can I have it so that the schema text file is mmost portable but ensures that when used with mysql that it uses the correct engine? <will> mishehu, You can set the default type to InnoDB. <will> I have no idea how since I've never done it. Might be in the CREATE DATABSE... <firewire> what was the question? <litheum> set storage_engine='InnoDB' <litheum> can do it locally or globally <teddyns> hi all <teddyns> how can I give access to database "alo" for IP 127.0.0.5 ? <firewire> use grant <teddyns> exact command of it ? :D I can login mysql as root then ? <firewire> mysql.com/grant syntax <scud_> im running mysql 4.0 and i have my index auto_increment. i have ids 1 to 10, when i delete say 3 and add another record, it puts record 11 after 2 in the index <scud_> whats up with that? <scud_> so listing select * from table; it would list the records 1, 2, 14, 4, 5 <Punkcut> can someone tell me the appropriate formula for deciding query_cache_size? <Ord0g> hi, is there a way to define in a LIKE where_clause which char might be there or not? like where 'this' like '{here might be a "~"}$ident@%' <firewire> big enough that you're not constantly out of free blocks <HubertRoksor`> Punkcut: SET GLOBAL query_cache_size = n * 1024 * 1024 <Ord0g> because % catches longer words and _ will still match on more than exactly those that i want <HubertRoksor`> (where n is the number of MB) <HubertRoksor`> Ord0g: you could use RLIKE, but it would be quite slow <HubertRoksor`> you should go with two queries in an UNION instead <archivist> scud_ use order by <HubertRoksor`> or simplier: WHERE field LIKE 'foo' OR field LIKE '~foo' <Ord0g> myISAM does not support nested queries afaik <Ord0g> or do you mean something different <Xgc> Ord0g: Try MySQL 4.1 or better. <HubertRoksor`> UNION is available since... err 4.0 or 4.1 <HubertRoksor`> 4.1? wasn't sure about it <Ord0g> MySQL 4.1.11-Debian_4sarge2-log running on localhost <Xgc> UNION has been available since before 4.1. <Ord0g> its about the nested queries ... i guess im missing something <Xgc> Ord0g: Nested queries are supported in 4.1 or better. <Ord0g> ok so it doesnt interfere with the db type ? <Xgc> No <Ord0g> oh <Ord0g> Try to avoid complex SELECT queries on MyISAM tables that are updated frequently, to avoid problems with table locking that occur due to contention between readers and writers. <Ord0g> how much is frequently ... <will> HubertRoksor`, UNIONs are availabe as of 4.0 <Ord0g> For MyISAM tables that change frequently, you should try to avoid all variable-length columns (VARCHAR, BLOB, and TEXT). The table uses dynamic row format if it includes even a single variable-length column <Ord0g> now thats interesting <Ord0g> could somebody explain the disadvantages of dynamic row format ? <Julian|Work> It's slow. <Julian|Work> If you know this static-length column takes up 32 bytes every time, you can scan to the 33rd byte to skip it. <Julian|Work> Otherwise, you need to figure out how long the column is for each row. <Julian|Work> Instead of + - * /, you're doing scans all over the place. <will> Of course, with a smaller row size, you can read more rows at a time. <Ord0g> varchar needs a length param <will> And? <Ord0g> text doesnt <will> So? <Ord0g> works for me without declaring it ... dont know if theres a default <Ord0g> i missed <stormchas3r3> command to create a p***word for mysql? <CPUnerdX> !m stormchas3r3 grant <SQL> stormchas3r3: (GRANT and REVOKE Syntax) : http://dev.mysql.com/doc/mysql/en/GRANT.html <CPUnerdX> !m stormchas3r3 set p***word <SQL> stormchas3r3: (SET P***WORD Syntax) : http://dev.mysql.com/doc/mysql/en/SET_P***WORD.html <stormchas3r3> ty <Ainslee> is mysqldump what i want to use if i want to import databases from one server to another? <alien3d> hello <alien3d> anybody have set in winxp <alien3d> two server <alien3d> one pc for php and one for mysql <Ord0g> alien3d no but i dont think one should have a problem with that <Ainslee> i've managed to save all my databases as sql files, will i need to manually put them on the server and then import? as i have them sitting on one pc now which is not where the server is locate <Ainslee> d <ChairoNoMe> What could be causing mysql to lock up when I issue a TRUNCATE TABLE command? <will> ChairoNoMe, You <ChairoNoMe> will: if I pay for commercial mysql support, does it come with the snide remarks? <will> Usually not. <ChairoNoMe> great <ChairoNoMe> It's weird what's happening <will> I can only imagine. <ChairoNoMe> I issue a TRUNCATE TABLE table and it just sits there <ChairoNoMe> i suppose it has something to do with the size of the table <ChairoNoMe> the table has a million rowsw <ChairoNoMe> rows <will> Shouldn't be because as far as I know, it will delete the table. Are there any other queries running that is using that table? <ChairoNoMe> it's a live server, so yeah. <ChairoNoMe> it's serving web customers <ChairoNoMe> wait <will> For how long? <ChairoNoMe> sorry i misheard you <ChairoNoMe> there's nothing else using the table <ChairoNoMe> other people using the database, yes. <will> Is the server doing anything when you issue the TRUNCATE? Like CPU usage? Disk usage? <will> What kind of table are you dropping? InnoDB? <ChairoNoMe> myISAM <will> Are you sure? <ChairoNoMe> alright <ChairoNoMe> i figured out <ChairoNoMe> there was a rogue process using the table <will> :) <will> You figured it out???? <ChairoNoMe> you know what would be really useful? Something to tell you when you issue the command that that table is in use <will> *YOU* ??? <will> :) <will> Request it. Make it. <will> Usually people check to see if it's use, lock it, etc. <arrase> hi <arrase> Can you explain me how can i get the values of the last entry in a table? if i use select max(idcolum) from table takes de biggest value not the last entry. Sorry for my english :) <murdoc> yes <murdoc> the max command takes highest value <murdoc> hmm.. <murdoc> do you have id column? <murdoc> with auto_increment option enabled? <arrase> i have id colum but increment...... <arrase> nop <will> Define "last entry". <will> Imagine your table as a gl*** jar. Imagine each row as a marble. When you insert rows into the table, it's like putting marbles into a jar. <will> In all honesty, MySQL doesn't know what marble was put in last. You have to 'tag' it somehow, like an autoinc or timestamp.
