This article is to share with you about the crash of PROC access Oracle. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Concept:

An application program that is developed by embedding SQL statements in the procedural programming language CCompact +. The SQL used in the general programming language is called embedded SQL.

Embedded SQL in many languages is defined in SQL standard, and different manufacturers have different implementations of embedded SQL.

The application program developed by embedding the SQL statement in the C + + language is called the Pro*C/C++ program.

Part of the system accesses ORACLE using PROC method, which first writes pc files, then uses PROC to convert pc files into cpp files, and finally participates in the compilation of cpp files. If the cpp files in the code are generated by 32-bit PROC, the cpp file compiles normally for both 32-bit and 64-bit cpp files, but there will be problems at run time. The current solution is to convert pc files into cpp files with 64-bit PROC on Linux, and the 64-bit audit engine compiled using these cpp files can run normally.

It is recommended that only the pc file be saved in the project code, and the corresponding cpp file should not be saved, so that the cpp file will be generated from the pc file in which environment it needs to run, and it must be able to run normally.

Thank you for reading! This is the end of the article on "what happened to the collapse of PROC access Oracle". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, you can share it for more people to see!
