Re: [sqlite] Data Manipulation ?
Richard, If you need any help I'm available under contract. I'll be in L.A. next week on business with a client, but otherwise I will be free. I've been programming for 10+ years and what you need done is very simple and I could charge for a minimum number of hours and you will have a full functional solution.

Re: [sqlite] Including sqlite3 in a GNU project
Mike, This only tries to find existing installations of sqlite3. I said I want to include a version of sqlite3 in my GNU project, have GNU tools auto configure and compile it - then use libtool to link against the static object.

Re: [sqlite] Re: sqlite3_busy_timeout
Let me see if I understand this correctly: So calling sqlite3_busy_time() allows you sleep for a max of N ms if the database is busy. Basically this function polls for you? When the database is free, it will return with SQLITE_DONE or SQLITE_ROW? What happens if the database never gets free? Will sqlite3_busy_timeout() just return SQLITE_BUSY?

Re: [sqlite] Including sqlite3 in a GNU project
I have found the following link that inspired Gnome-DB to use SQLite. http://aaronbock.net/articles/sqlite/ But this method only uses the sqlite-source.zip which are just the pure C files. I want to use the sqlite3.tar.gz distribution that uses GNU tools.

[sqlite] Including sqlite3 in a GNU project
Has anyone went through (what I feel is a painful process) of adding sqlite in a GNU project? I'm not referring to sqlite specifically, but just with the GNU tools in general. I would like to copy the sqlite distribution into my project directory and just extract it. Then modify my configure.in and Makefile.am to auto-magically configure sqlite, then go ahead and compile my project and link my project against the static archives of sqlite, for example: gcc obj1.o obj2.o obj3.o ../sqlite3-X.X.X/libsqlite3.a -o binary_name Any ideas? -- - Doug Hanks = dhanks(at)gmail(dot)com
[sqlite] How to bind DATE and TIME values
Hello,
I would like to use the sqlite3_bind_* functions to bind data to a
TIMESTAMP column.
With regular SQL I can use the following command:
INSERT INTO TABLE (completed) VALUES(date('now'));
The data('now') function returns the current date.
What is the correct method in the C API to have the same functionality?
If there is a better way to handle timestamps perhaps with another
column type, please let me know. I am flexible.
