アプリを更新した後、sqlite データベースに問題があります。アプリがクラッシュします。これが私のログですが、何が間違っているのかわかりません:

行 11 は、関数内の関数 sqlite3_prepare_v2 に問題があることを示しています。
- (BOOL) checkIfTableExist:(NSString *) tableName
{
BOOL exist = NO;
sqlite3_stmt *stmt;
NSString *sql = [[NSString alloc] initWithFormat:@"SELECT name FROM sqlite_master WHERE type = 'table' AND name = '%@'", tableName];
if (sqlite3_prepare_v2(database, [sql UTF8String], -1, &stmt, NULL) == SQLITE_OK) {
if (sqlite3_step(stmt) == SQLITE_ROW)
exist = YES;
sqlite3_finalize(stmt);
}
[sql release];
return exist;
}
アプリを更新した後、データベース ファイルが壊れたなどの可能性がありますか?
