The design of ecpg follows the SQL
standard. Porting from a standard RDBMS should not be a problem.
Unfortunately there is no such thing as a standard RDBMS. Therefore
ecpg tries to understand syntax
extensions as long as they do not create conflicts with the
standard.
The following list shows all the known incompatibilities. If you
find one not listed please notify the developers. Note, however,
that we list only incompatibilities from a preprocessor of another
RDBMS to ecpg and not
ecpg features that these RDBMS do not
support.
- Syntax of FETCH
The standard syntax for FETCH is:
FETCH [direction] [amount] IN|FROM cursor
Oracle, however, does not use the
keywords IN or FROM. This
feature cannot be added since it would create parsing conflicts.
