DB2嵌入式编程，语句“EXEC SQL INCLUDE”说明

There are two methods for including files: the EXEC SQL INCLUDE statement and the #include macro. The precompiler will ignore the #include, and only process files included with the EXEC SQL INCLUDE statement.

To locate files included using EXEC SQL INCLUDE, the DB2 C precompiler searches the current directory first, then the directories specified by the DB2INCLUDE environment variable.
