Sql Program File Format; Figure 6-4. Sql/Mp Program File Format - HP NonStop SQL/MP Programming Manual

Explicit Program Compilation

Insufficient information. The SQL compiler does not have enough information to
determine the validity of a statement. For example, an unavailable table might not
exist, or it might reside on an unavailable remote node. (This situation always
occurs for a program that both creates and refers to a table. The table, of course,
does not exist when the program is explicitly SQL compiled.)

Unresolved DEFINEs. An SQL statement references a nonexistent DEFINE.

SQL Program File Format

The input program file to the SQL compiler can be a C object file, a file generated by
the Binder program, a file generated by the Accelerator, the OCA, or a file previously
compiled by the SQL compiler.
