You have apparently taken an RPM for RHEL5 and attempted to use it in RHEL4. It should not be a surprise that it doesn't work. To get it working, either use the correct RPMs (which may not be available), compile from source yourself, or upgrade to RHEL5. --keith -- kkel...@wombat.san-francisco.ca.us -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql

Use cut to extract only the columns of your primary key, use sort (not with -u!) to sort the rows, and use uniq -d to print out only duplicate lines. e.g. cut -f1 mytable.tab | sort | uniq -d It won't tell you which line number(s) are problematic, however; it just tells you which values for your PK are duplicated. If you need the line number use one of the other suggestions. --keith -- kkel...@wombat.san-francisco.ca.us -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql

Re: Emergency backup from *.frm *.MYD *.MYI files
On 2012-06-09, Miguel Cardenas renit...@gmail.com wrote: My linux system died due a bad system driver and it does not boot ANYMORE, I am backing up my data files to restore a previous worlking backup of the whole system that DOES NOT INCLUDE THE DATABASES... I hope you will be correcting that in the future! I'm still backing up and will take some time before restore the system, in the mean time I want to know if I can restore the databases from the *.frm *.MYD and *.MYI files, maybe creating the databases again and replace them with the old data files? If they are MyISAM tables, then you should be able to restore most of your tables in this fashion. It depends on how often these tables are written to; if they get writes very frequently then they may be too inconsistent to recover. The basic process is to create the directory (either with CREATE DATABASE or directly on the filesystem; make sure the mysql user can write the directory), then copy the files in to the directory (make sure nobody is doing any writes to the db during this process, and make sure the files are owned by the mysql user when done). This is basically how mysqlhotcopy works--it locks the tables, then copies the raw files to the destination. Your only potential problem is that the tables were open at the time, so changes might not have been written before your crash. Once you have copied the needed files, you should run myisamchk (make sure mysqld is *not* running) on the *.MYI files. --keith -- kkel...@wombat.san-francisco.ca.us -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql

temp tables rights?
Hi all, Suppose I have a user who has been granted select and create_tmp_table, but no other privileges, on a given database. When I attempt to insert into any temporary table, permission is denied, presumably due to the user not having insert on the database, and no entries in mysql.tables_priv for the new temporary table. Is there an accepted and clean way of allowing users without insert to insert into their own temporary tables? This message http://lists.mysql.com/mysql/156829 from January seems to imply that no such method exists. There are two workarounds: either the one the above message suggests (make the appropriate entries in tables_priv in advance, creating a static allowable set of temporary table names), or grant insert on the database, and then revoke insert on all of the existing tables in the database. This second method seems clunky in two ways: if you subsequently create a new table that shouldn't allow inserts, you need to remember to revoke insert on that table; it also will clutter tables_priv quite a bit. We're using 4.0.17 at the moment; the 4.0.18 and 4.1.1 changelogs don't seem to address this issue. Hopefully I'm wrong, and someone will point out the correct way to do this; if not, what's the preferred alternative?
