2016年7月4日 · intermixing regular C with Pro*C statements (as you can see) and then you run it through the Pro*C compiler. What comes out of that is a C program which has the Pro*C statements replaced with the equivalent function calls which will do the same thing.

2014年2月21日 · There is of course a bug in there (well, at least one!) that I kind of left on purpose. If your database fields are 10 and 32 characters as I made mine, then the size of the VARCHAR elements - or your original char elements - needs to be one byte large to hold the terminating null - which is of course basic C stuff, so it's entirely possible your real columns are …

2012年10月15日 · I'm new to pro*c coding and oracle. I need to insert data into various tables at run time depending on certain condition. Can anyone point me if I can implement the same using dynamic sql method4. Reading through the doc Im really confused. Oracle doc gave some really nice examples but really confusing.

2012年2月20日 · Pro*C is old. I worked on the first beta of Pro*C 25+ years ago. ...not recommended. The code generated by Pro*C pre-compilation does not always do perfectly when compiled by modern compilers with warnings enabled. It also is not meant to be readable. If you want to learn OCI programming, you can get what is going on.

2014年6月23日 · What is the best way to achieve this using Pro *C? I came across a few useful articles here & here but I just want to check if there is a more suited solution to my use case. It will be also useful to weigh the pros and cons of options that I might have.

2021年8月11日 · Thanks Alex, Actually the main task is to access the oracle DB located in the remote PC using pro*c. I will go through the installation guide. – Alok Ranjan Swain

2015年8月1日 · This is simply because Pro*C commands may expand to several lines of C code, which all got the same line number assigned. I've had colleagues in my room use Pro*C a long time ago, and I vaguely remember that they were able to debug. Also, as John Bollinger comments, it should all be possible because Pro*C is just a preprocessor which outputs ...

2014年8月29日 · Been years since I did any Pro*C, but I remember when I first came across this in an earlier version of Pro*C, and you had to use indicator variable to check if the value was NULL or not. That changed however when Oracle introduced the STRING datatype. I liked this so much I even started to TO_CHAR numbers and store them to STRING.

2015年5月20日 · You can link external libraries (Windows DLL or UNIX ".so" files) to Oracle and then make them callable via PLSQL.
