SQLite database - cannot see updates - iphone

Question

I have a sqlite database and I am adding to it new words. The problem is that I can see them added to a table only after restarting application. The "SELECT" statement doesn't "see" newly added elements before restarting application.
Why may this happen?
I am creating some kind of a dictionary. Here is how I add new items:
const char *sql_query = "INSERT INTO words(word) VALUES(?)";
if(sqlite3_prepare_v2(database, sql_query, -1, &addWordsStmt, NULL) != SQLITE_OK)
{
return FALSE;
}
sqlite3_bind_text(addWordsStmt, 1, [ word UTF8String], -1, SQLITE_TRANSIENT);
if( sqlite3_step(addWordsStmt) != SQLITE_DONE)
NSAssert1(0, #"Error while inserting data. '%s'", sqlite3_errmsg(database));
sqlite3_reset(addWordsStmt);
sqlite3_finalize(addWordsStmt);
And here is my retrieval code:
const char *sql_query = "SELECT word FROM words WHERE id=?";
if(sqlite3_prepare_v2(database, sql_query, -1, &getWordsStmt, NULL) != SQLITE_OK)
{
return;
}
sqlite3_bind_int(getWordsStmt, 1, wordid);
if( sqlite3_step(getWordsStmt) != SQLITE_ROW)
{
NSLog(#"Error while getting data. '%s'", sqlite3_errmsg(database));
sqlite3_reset(getWordsStmt);
return;
}
NSString *word = [NSString stringWithUTF8String:(char *)sqlite3_column_text(getWordsStmt, 0)];
sqlite3_reset(getWordsStmt);
sqlite3_finalize(getWordsStmt);

Answer 1

My guess is that you are in a transaction. There must be some other calls during your open and close routines that are wrapping your calls in a transaction and not displayed in your code fragments.
That is why you don't see the new words until you application exits

Answer 2

There's your problem:
const char *sql_query = "SELECT word FROM words WHERE id=?";
This isn't how you use SQL. Instead, you should be using SELECT word FROM words; and stepping to get each row as long as you're getting SQLITE_ROW until you get SQLITE_DONE. That will get you all your words. How are you going to find a word by id when you don't know the id of newly added words?
