First off a Disclaimer: I'm a noob and still learning. Please don't bash me like some forums. Now to the questions: I'm searching for a quick and easy way to integrate SQLite3 in my application. I came across the etc.c.sqlite3 and the DSQLite library(https://github.com/bioinfornatics/DSQLite). Thinking that the C bindings is more documented I tried learning that. Though I can't understand the arguements of the callback function. extern(C) int callback( void* NotUsedAtAll, // Null variable int argc, // What? char** results, // Results? char** columnNames //Column Names? ){ for(int i = 0; i<argc; i++){ writeln(results); getchar(); } I've been reading through many explanations about this and I understand why the callback is needed but I can't seem to understand how to really use the callback function. Can someone provide a brief explanation or just point me in the right direction? |

Jokes aside, I guess this proves I'm getting ahead of myself. Thanks for the article.

I think I got it covered for now. |

May as well throw an undocumented library at you: https://github.com/JesseKPhillips/SQLite3-D I only used it to pull data out of SQLite database. Once you have your db object it is something like this. foreach(data; db.query(statement).range!Structure)... Where you define a struct with Nullable!() types your statement pulls out. |

I seem to have a problem with that library. Even if the modules have been imported and the libraries linked and yada yada, it spews error upon error. Sample code is this: import std.stdio; import ddbc.drivers.sqliteddbc; void main(){ SQLITEDriver driver = new SQLITEDriver(); writeln("SUCCESS"); } Error spewed out is this: hello.d|7|Error: undefined identifier SQLITEDriver| I think Code::Blocks is importing the modules but not detecting the modules. Been at it for a few hours now. Any help?

Sounds easy enough, I'll take a look at it. Thank you ... |

Did you specify the configuration to use to dub?
dub -c SQLite
