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.
If you see anything in the documentation that is not correct, does not match your experience with the particular feature or requires further clarification, please use this form to report a documentation issue.
