Info

OTT Utility Reference If CASE=OPPOSITE, then all uppercase letters are converted to lowercase, and all lowercase letters are converted to uppercase. CASE=[SAME|LOWER|UPPER|OPPOSITE] This parameter affects only those identifiers (attributes or types not explicitly listed) not mentioned in the INTYPE file. Case conversion takes place after a legal identifier has been generated. The case of the C structure identifier for a type specifically mentioned in the INTYPE file is the same as its case in the INTYPE file. For example, consider this line included in the INTYPE file: TYPE Worker The OTT utility generates the following C structure: struct Worker {...}; On the other hand, consider an INTYPE file that includes the following line: TYPE wOrKeR The OTT utility generates this C structure, which follows the case specified in the INTYPE file: struct wOrKeR {...}; Case insensitive SQL identifiers not mentioned in the INTYPE file will appear in uppercase if CASE=SAME, and in lowercase if CASE=OPPOSITE. A SQL identifier is case insensitive if it was not quoted when it was declared. CODE Parameter This parameter indicates which host language is to be output by the OTT utility. CODE=C is equivalent to CODE=ANSI_C. CODE=CPP must be specified for the OTT utility to generate C++ code for OCCI applications. CODE=C|KR_C|ANSI_C|CPP This parameter is required, and there is no default value. You must specify one of the host languages. 7-120 Oracle C++ Call Interface Programmer’s Guide
OTT Utility Reference CONFIG Parameter This parameter specifies the name of the OTT configuration file to be used. The configuration file lists commonly used parameter specifications. Parameter specifications are also read from a system configuration file found in an operating system-dependent location. All remaining parameter specifications must appear either on the command line or in the INTYPE file. CONFIG=filename Note: The CONFIG parameter can only be specified on the OTT command line. It is not allowed in the CONFIG file. CPPFILE Parameter For C++ only. This parameter specifies the name of the C++ source file that will contain the method implementations generated by the OTT utility. This parameter is required under the following conditions: ■ A type not mentioned in the INTYPE file must be generated and two or more CPPFILEs are being generated. In this case, the unmentioned type goes in the CPPFILE specified on the command line. ■ The INTYPE parameter is not specified, and you want the OTT utility to translate all the types in the schema. The restrictions to this are similar to that of the existing HFILE parameter restrictions already in place for Pro*C/C++ and OCI. This parameter is optional when the CPPFILE is specified for individual types in the INTYPE file. CPPFILE=filename ERRTYPE Parameter If you supply this parameter, then a listing of the INTYPE file is written to the ERRTYPE file, along with all information and error messages. Information and error messages are sent to the standard output whether or not the ERRTYPE parameter is specified. Essentially, the ERRTYPE file is a copy of the INTYPE file with error messages added. In most cases, an error message will include a pointer to the text that caused the error. How to Use the Object Type Translator Utility 7-121
