where as in an array that is n items long the valid array elements are from 0 to n-1 in a database the key field is from 1 to n simple enough to work around if you just keep that in mind. it works just slightly different then an array's key. btw if your using an auto increment int for the primary key. Numrows= sqlite3_column_int(selectStatement, 0) If(sqlite3_step(selectStatement) = SQLITE_ROW) To retrieve data after executing a SELECT statement, you can either treat the cursor as an iterator, call the cursor’s fetchone () method to retrieve a single matching row, or call fetchall () to get a list of the matching rows. Moreover, it does not need any column names/key field to consider. Int returnValue = sqlite3_prepare_v2(database,, -1, &selectStatement, NULL) spspaceused can be used for any table, it's very helpful when the table is exceptionally big (hundreds of millions of rows), returns number of rows right a way, whereas 'select Count(1)' might take more than 10 seconds. If(sqlite3_open(, &database) = SQLITE_OK) However, if you just need the first 10 rows in the result set, you can add the LIMIT clause to the SELECT. For example, a SELECT statement may return one million rows. The COUNT() function, which is used for counting the total number of rows in a certain table or query result, is one of the features that make SQLite a. You use the LIMIT clause to constrain the number of rows returned by the query. and I tested it in an ios app it's available in there too behold: sqlite3 *database The LIMIT clause is an optional part of the SELECT statement. I thought I'd trow in my two cents here as there is an expression to count rows in a database, I use it when dealing with MySQL databases using php scripts all the time.
