PEAR::DB == || != DBA

After taking a hard look at database abstraction and choosing PEAR::DB as my abstraction layer tool. It occurred to me that this does not quite fit the bill. The main problem being escaping strings before insertion and selection. Because many databases, example MySQL, Oracle & Sybase, do not escape characters in the same manner, and because the string escape is not implemented (at least I couldn't find it) in the PEAR::DB module, then you are left to escape the string in a manner appropriate to each database outside the PEAR::DB module. Adding to this the fact that here is no PHP function that correctly escapes all characters for all databases, then complete DBA is not a possibility by strictly using PEAR::DB. You must encapsulate PEAR::DB with your own DBA to achieve the desired result. Is this a fair and accurate assumption? Or am I missing something? Thanks for your time and attention. Eric Stewart
