Summary: unixodbc broken by escaping stuff

Initial Comment:
Hello,

As I noted before in the mailing lists, the code submited here to escape SQL queries CAN NOT, WILL NOT and DOES NOT work.

It seems that the error is now engraved even deeper in the core files since sql_escape have been replaced by escape_common in core files.

Apart than the fact that this is not the way SQL queries must be escaped (depends on the SQL engine you use, for one thing, and backslashes are NOT widely accepted), the current code just totally breaks unixodbc :

Doing the job properly requires more time and thinking (I tried to lauch the conversation, but I believe it was considered too complicated for 1.2), so in the meantime please find attached a patch to revert the changes.

I am using my own patches anyway to handle my particular case (SQL server, which requires escaping ' in strings by ''), so do what you wish. If anyone is motivated about this, I'll be happy to give details on my DB server and how I need to escape strings, but really I think this is for 1.2.1.

Regards,
Jerome
