ODBC... If you're working with any C-based tools, that is. Perl, Python, Ruby, PHP, etc. -- they all have ODBC libraries. JDBC, if you're working with Java-based. Use ODBC/JDBC and SQL standards-compliant calls -- avoid DBMS-specific dialect -- and you should find that things go pretty well. Changing DBMS is in all these cases just a matter of changing the ODBC DSN or JDBC URL -- and of course, having the relevant driver in place. For full Cocoa ODBC support, you'll need to either build from source or download a pre-compiled set of the iODBC Frameworks, as Apple has chosen to only ship the dylibs. < http://sf.net/projects/iodbc>, <http://iodbc.org/>, or <http://download.openlinksw.com/download/product_matrix.vsp?p=f_db&fm=1&fam=7&of=5>. I will observe that free drivers are often worth what you pay for them, with incomplete and/or imperfect implementations of some API calls, but there are plenty of options out there. (I work for one driver vendor, OpenLink Software, which also happens to be the maintainer/supporter of the open source iODBC Project, which is the basis of the ODBC libraries on Mac OS X. We don't make any money until/unless someone chooses to buy one of our drivers -- the iODBC SDK is free in all ways, and all our drivers and other commercial products have free download and 14-day (renewable) testing licenses, and free up-and-running support; upgrading to permanent license only requires a new license file. ) Be seeing you, Ted _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
