## 30.10. Including Files

To include an external file into your embedded SQL program, use:

    EXEC SQL INCLUDE filename;

The embedded SQL preprocessor will look for a file named ``filename`.h`, preprocess it, and include it in the resulting C output. Thus, embedded SQL statements in the included file are handled correctly.

Note that this is not the same as

    #include <filename.h>

because this file would not be subject to SQL command preprocessing. Naturally, you can continue to use the C `#include` directive to include other header files.

### Note

The include file name is case-sensitive, even though the rest of the `EXEC SQL INCLUDE` command follows the normal SQL case-sensitivity rules.
