I have a query that should return results and sqlite3_step is, sometimes,
returning SQLITE_DONE instead of SQLITE_ROW.
I have a table, meta_data, with two columns
id INTEGER primary key, Soundid INTEGER
which I know at the time of execution has the rows
ID SOUNDID

You Need to bind for each insert, Sqlite does not bind by address it does a
copy.
You'll need to populate your variables inside the loop then bind then step:
prepare_v2
for(i = ...) {
assign Variables to be bound.
sqlite bind for each variable/column
Hi All,
I have the following code:
bool insert(Uccls *_uccls, TCPAcclBucket *tcpAcclBucket){
int nextCol;
memcpy(, tcpAcclBucket, sizeof (TCPAcclBucket));
bindColumns for tcpAcclRec
//Execute statement
I have an application that does bulk INSERTS into a table. Simplified
pseudo code is below:
sqlite3_open(dbh);
sqlite3_prepare(stmt);
for (i=0; i < 10; i++) {
sqlite3_bind(i);
sqlite3_step(stmt);
sqlite3_reset(stmt);
}
sqlite3_close(dbh);
While the bulk INSERTs are being

Hi all,
I'm having problems with the sqlite3_step function.
I have a table with only one record and then I execute the
sqlite3_step twice (with some processing in between). In the first run
of the function everything goes fine, but, in the second one, it
returns SQLITE_ROW even with only one
Ive been getting SQLITE_MISUSE errors after calling sqlite3_step one
more time than required. Im using sqlite3_prepare_v2 so im expecting
detailed error messages, but when i call sqlite3_errmsg all i seem to
get is "not an error".
So my question is this. What is an error ? It seems a little

I beg to differ. Any stack trace that includes malloc or free is almost

If you think the problem is in SQLite and not in your
own code, then you should do as much of the following
as you can:
