出于某种原因,我的应用程序在 "NSAssert1(0, @"Error while looping search view.'%s'", sqlite3_errmsg(database));"处失败 SQL 语句是可以的,因为我在打开数据库时使用了相同的语句。我没有得到任何有用的错误:-(

我对此很陌生,但不是一个完全陌生的人我做错了什么?

请注意,我已取出“strSearch”以确保这不是错误。

- (void)searchComponents:(NSString *)strSearch {

    NSString *qry;

    qry = [NSString stringWithFormat:@"SELECT ID, ON_SAP, SAP_PART, SAP_DESC, MOQ FROM HONEYWELL WHERE SAP_PART LIKE '%ZX%' ORDER BY SAP_PART", strSearch];
    NSLog(@"query : %@", qry);

    if(searchStmt == nil) {
        if(sqlite3_prepare_v2(database, [qry UTF8String] , -1, &searchStmt, NULL) != SQLITE_OK)
            NSAssert1(0, @"Error while creating search view statement. '%s'", sqlite3_errmsg(database));
    }

    // Loop through the results

    if(sqlite3_step(searchStmt) == SQLITE_ROW) {
        // Read the data from the result row
        NSLog(@"New row selected");
    }
    else {
        NSAssert1(0, @"Error while looping search view. '%s'", sqlite3_errmsg(database));
    }

    // Release the compiled statement from memory
    sqlite3_finalize(searchStmt);

    // Set isDetailViewHydrated as YES, so we do not get it again from the database.
    isDetailViewHydrated = YES;
}

该方法在它自己的类(名为 Coffee)中,从 MasterViewController 调用

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
    NSLog(@"Text changed %@",searchText); 
    Coffee *coffeObj = [[Coffee alloc] init];
    [coffeObj searchComponents:@"%ZX%"];
}

这个想法是在从搜索字段搜索时更改选择语句。有没有人知道这样做的好例子?

问题已解决,我错过了重置

sqlite3_reset(searchStmt);
