Memory management when using sqlite database in iphone

Question

My application makes use of a SQLite database to store the user\'s inputs. The number of records in the input would go to around 100 records and I have a lot of SQL operations g

Answer 1

You really want to limit the cache size of sqlite in iphone applications. When you launch your application and initialize your database run a command like:

const char *pragmaSql = "PRAGMA cache_size = 50";
if (sqlite3_exec(database, pragmaSql, NULL, NULL, NULL) != SQLITE_OK) {
    NSAssert1(0, @"Error: failed to execute pragma statement with message '%s'.", sqlite3_errmsg(database));
}

this will prevent sqlite from caching your queries and slowly consuming all of your memory.
