Inquiry:MySql table data missing problem
Dear All Can you please do me favor and let me know what is wrong with my MySql db installed on Linux server that causes to get the following error message : "Fail to insert cdr:Can't open file: 'cdrFromMSC_06.MYD'. (errno: 145)" Your reply is highly appreciated Regards H.Motamedi
Re: Renaming a Database
No... I've pretty much avoided those. This WAS a Visual FoxPro app so we're still at the stage where we really aren't "leveraging" MySQL specific features. We're still pretty much just eliminating VFP specific things. Hence the one time nature of this renaming. Now that we're 5-10 customers in to upgrading we decided to actually define a naming convention for the databases themselves so I've got to fix the 5-10 that are already out there (I could not change it... but then we have to "remember" that these are special cases) On Wed, Aug 19, 2009 at 10:28 AM, Rolando Edwards wrote: > If you have stored procedures, don't forget to update the db column with the > new db in mysql.proc as that does not automatically change. > > Rolando A.

RE: text records and cross referencing
Hi Pol, MySQL support FULLTEXT indexes, and natural language searches, including Boolean conditions. This may help you; however, you will have to adjust the default behavior of the index, but changing server settings. By default there is a minimum word length which you will have to adjust, and a list of stopwords (words to ignore.) Both of these will prevent you from indexing each and every word, and even still words that show up in most or all records will be ignored (and I don't know if you can change that behavior.) The alternative, is using unindexed lookups, which would be very slow for any non-trivial application. See: http://dev.mysql.com/doc/refman/5.0/en/tutorial.html http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html The highlighting and switching behavior is up to your application. MySQL just stores data, it's up to you to write programs that manipulate it. In all honesty, if this really is a "personal" application, you may be better off using another, simpler method.

RE: Renaming a Database
If you have stored procedures, don't forget to update the db column with the new db in mysql.proc as that does not automatically change. Rolando A.
