I understand "SELECT last_insert_rowid()" gives rowird, but I have to call these SQL statements in C language code, for that I have to sqlite3_prepare and sqlite3_step() calls, I am looking for sample of sqlite3_step, how that return the rowid, can I call like this:
int rowid; sqlite3_stmt *pStmt; sqlite3(pDB, "SELECT last_insert_rowid()", -1, &pStmt, 0); rowid = sqlite3_step(pStmt); On Mon, Feb 8, 2010 at 2:36 PM, Kees Nuyt <k.n...@zonnet.nl> wrote: > On Mon, 8 Feb 2010 11:44:39 -0500, Vasanta > <vtan...@gmail.com> wrote: > > > I tried to use this function call > > "sqlite3_last_insert_rowid()< > http://www.sqlite.org/c3ref/last_insert_rowid.html>" > > calling from C language function, but it always returns zero, any idea?. > > I have valid DB handle. > > The function only returns the rowid of the last successful > INSERT statement on the same connection / DB handle.
