The design of ecpg follows SQL standard. So
porting from a standard RDBMS should not be a problem. Unfortunately there
is no such thing as a standard RDBMS. So ecpg
also tries to understand syntax additions 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
Michael Meskes.
Note, however, that we list only incompatibilities from
a precompiler of another RDBMS to ecpg and not
additional ecpg features that these RDBMS do not
have.
Syntax of FETCH command
The standard syntax of the FETCH command is:
FETCH [direction] [amount] IN|FROM cursor name.
ORACLE, however, does not use the keywords IN
resp. FROM. This feature cannot be added since it would create parsing
conflicts.
