Update of /cvsroot/mysql-cocoa/SMySQL
In directory usw-pr-cvs1:/tmp/cvs-serv11778
Modified Files:
SMySQLConnection.h SMySQLConnection.m SMySQLResult.h
SMySQLResult.m
Log Message:
Corrected the method listFields: fromTable:.
Finished the proper character set encoding for all the method. This version should be as transaprent as possible with non ascii character encoding (as far as the charset used by mysql is known from Mac OS X).
Incremented the version to 0.5.5

/*"
Select the encoding used by the server for data transfert. This is usefull for the output NSString (query result) to be Ok even for character which are not ASCII
+ NB: The character set (encoding) used by the db is passed to the SMySQLConnection object upon connection, so most likely the encoding (from -encoding) method is already the proper one. That is to say : It's unlikeley you need to use this method, and if ever you use it, do it at your own risks.
