Including embedded SQL commands v17
EDB enhanced ECPG (the PostgreSQL precompiler) to create ECPGPlus. ECPGPlus allows you to include Pro*C-compatible embedded SQL commands in C applications when connected to an EDB Postgres Advanced Server database. When you use ECPGPlus to compile an application, the SQL code syntax is checked and translated into C.
ECPGPlus supports:
- Oracle Dynamic SQL – Method 4 (ODS-M4)
- Pro*C-compatible anonymous blocks
- A
CALLstatement compatible with Oracle databases
As part of ECPGPlus's Pro*C compatibility, you don't need to include the BEGIN DECLARE SECTION and END DECLARE SECTION directives.
While most ECPGPlus statements work with community PostgreSQL, the CALL statement and the EXECUTE…END EXEC statement work only when the client application is connected to EDB Postgres Advanced Server.
