-# SQLite3 Adaptor
+# MySQL4 Adaptor
Note: this is far from being complete! The adaptor is currently a fork of
- the PostgreSQL adaptor.
+ the MySQL4 adaptor.
TODO
====
-- check EOAttribute+SQLite:
- -loadValueClassAndTypeUsingSQLiteType:...
-- SQLiteChannel.m:
- -primaryFetchAttributes => check field name processing
-- rewrite for exception less operation
-- implement more methods in SQLiteChannel+Model (hard with SQLite though)

Basics
======
Open a Shell:
- sqlite3 OGo
+ mysql --password=abc
+ > use OGo
> insert schema
> select * from date_x;
-Configure the Adaptor (below does not work yet for SQLite3!)
+Configure the Adaptor (below does not work yet for MySQL4!)
- Defaults write ogo-webui-1.0a LSAdaptor SQLite3

Defaults write ogo-webui-1.0a PKeyGeneratorDictionary \
