Another easy way to embed is to use embedded C/C++ Ch. All sqlite APIs are already supported in Ch and they can run in C/C++ interpreter Ch without compilation. You can use embedded Ch and then call all sqlite APIs. Ch Sqlite is open source and freely available from http://chsqlite.sourceforge.net/ More about Embedded Ch can be found at: http://www.softintegration.com/products/sdk/embedch/ http://www.softintegration.com/support/faq/embed.html http://www.softintegration.com/solution/embedded/ Peter > May not be worth the hassle given the size of your project. > > Since you're using C, consider rewriting your code using TrollTech's Qt > library so you could hook up any database for which they've written a driver. > There may be other multi-database libraries for C/C++. > - To unsubscribe, send email to [EMAIL PROTECTED] -
Re: [sqlite] Embedded SQL in C
We have an application server which incorporates Sqlite. It implements a proprietary language to generate embedded server pages and these use regular embedded SQL compiled into the executables. It also has a remote procedure call interface which accesses a repository of SQL using embedded SQl syntax bound to variable names in Javascript running in browsers. To implement a preprocessor which intercepts SQL in a C program and embeds calls to the Sqlite API would provide what you want. The Sqlite Bind call seems to have been implemented in such a way as to facilitate embedded SQL. Leif Jensen wrote: That sounds very interesting. Could you please elaborate a little more on that ?

May not be worth the hassle given the size of your project. Since you're using C, consider rewriting your code using TrollTech's Qt library so you could hook up any database for which they've written a driver. There may be other multi-database libraries for C/C++.

Re: [sqlite] Embedded SQL in C
Thank you for your ideas. I thought about the "fake" library myself even though our project is more like 20 - 30k lines, but I'm not sure how bad it would be. I'm aware of the SQL dialects, but we have tried to make a point of using "standard" SQL syntax. Of course we might have to develop some triggers/functions that are not available in SQLite at the moment. I was hoping someone had already done something along these lines before.

You'd only have to support the subset of libpq functions actually used by ECPG. But even if you did such a port using either approach, be aware that the SQL dialects of Postgres and SQLite are not the same - you'd likely have to change some of the embedded SQL statements in your code.
