Oracle C++ Call Interface Programmer's Guide

Overview of the INTYPE File
The lines that begin with the TYPE keyword specify which types in the database
should be translated. In this case, the EMPLOYEE, ADDRESS, ITEM, PERSON, and
PURCHASE_ORDER types are set to be translated.
The TRANSLATE ... AS keywords specify that the name of an object attribute
should be changed when the type is translated into a C structure. In this case, the
SALARY$ attribute of the employee type is translated to salary.
The AS keyword in the final line specifies that the name of an object type should be
changed when it is translated into a structure. In this case, the purchase_order
database type is translated into a structure called p_o.
If you do not use AS to translate a type or attribute name, then the database name of
the type or attribute will be used as the C identifier name, except that the CASE
parameter will be observed, and any characters that cannot be mapped to a legal C
identifier character will be replaced by an underscore character (_). Consider the
following reasons for translating a type or attribute:
■ The name contains characters other than letters, digits, and underscores
■ The name conflicts with a C keyword
■ The type name conflicts with another identifier in the same scope. This can
happen, for example, if the program uses two types with the same name from
different schemas.
■ The programmer prefers a different name
The OTT utility may need to translate additional types that are not listed in the
INTYPE file. This is because the OTT utility analyzes the types in the INTYPE file
for type dependencies before performing the translation, and it translates other
types as necessary. For example, if the ADDRESS type were not listed in the INTYPE
file, but the Person type had an attribute of type ADDRESS, then the OTT utility
would still translate ADDRESS because it is required to define the Person type.
Note: As of release 1 (9.0.1), you may indicate whether the OTT
utility is to generate required object types that are not specified in
the INTYPE file. Set TRANSITIVE=FALSE so the OTT utility will
not to generate required object types. The default is
TRANSITIVE=TRUE.
A normal case insensitive SQL identifier can be spelled in any combination of
uppercase and lowercase in the INTYPE file, and is not quoted.
