Has anyone compiled sqlite 3.3.8 under OpenWatcom 1.x ? I'm not
able to do it, because of this:
void (*interrupt)(sqlite3*);
in sqlite3ext.h ... seems to be, that interrupt is a reserved word
in OpenWatcom, but this is just a guess ...
Any idea ?

I've read the book from Michael Owens about SQLite and also
read the parts about threads and sqlite3.
Actually it seems to be possible to use the same connection
handler from different threads - but within a transaction
only one thread is allowed to access the library with that
particular
There are good reasons to have "NULL" values - though they can make the live
a bit harder. Use them - even Microsoft has found out, that they made a
big mistake
in .NET 1.x and corrected them in 2.0 by introducing nullable types.

I have written some interface code to the sqlite3 API using the
OpenWatcom 1.5 compiler and I wrapped several functions like
sqlite3_column_text, sqlite3_column_int and all went fine.

Is it possible to get the information, if a SQLite library one

How can I get all the names of a table without doing a query against the

I need all the names of columns within tables/views, the column index

I'm not sure how to use a function call in a prepared statement:

how to I bind the value of date('1964-04-01') to one of the

the internal date-function-call into that column ?

Indeed it may be questionable to use SQLite for stuff like this, but its a
very fast relational db library - and therefore it can be used as any other
relational database to store objects.
What is needed is very simple: you need a object-oriented relation database
wrapper - either as a

The "vertical" approach (described by Teg) leads also to a very

Has anything changed (calling conventions ?) between these (official)
versions (dll) under Windows? I have not found anything in the version
documentation.
I was not able to find/download 3.7.12/13/14/15 versions to find out,
where the problems started ?

Are the old prebuild binary versions (dll windows) available from
somewhere ?
