Class:SqlClass
Version:0.96
changes 0.9b->0.95:
Added error handling(except mssql and sybase)
I've found some bugs(I've tested it at least)
changes 0.95->0.96:
Added __sleep() and __wakeup() functions that are helpful when you're serialising the class. With them came some new vars (host, user etc.), but be careful, becouse the pass is only base_64 encoded. After unserializing the connection is avaible without any inits.
You can redistribute and change it as you only will
There are two classes:
sql- you should only this one, the seccond one will come to you with sql_class->exec();
___return___-I've wrote about this here upper
All methods except row_num with interbase are allowed to all database's
