FMDB resultset into dictionary

由 淺唱寂寞╮ 提交于 2019-12-03 12:25:56
问题 Is there an easy way to get the FMDB results of an executeQuery:SELECT * ... easily into a dictionary? FMResultSet *appointmentResults = [[DataClass getDB] executeQuery:@"SELECT * FROM Appointments WHERE date = ?",currDateString]; while ([appointmentResults next]) { //Create dictionary //Add dictionary to array for later use } I was wondering if there was a way I could make the dictionary keys the column names and the values the column values. Preferably without having to do a loop through

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I'm using FMDB to work with sqlite and I'd prefer to avoid a dependency on SQLCipher. How can I simply leverage the DataProtection capability built into iOS? Is this possible - the only requirement is to protect the data in the event of the phone being stolen. If the phone is unlocked with a PIN, it's fine that the user could access the DB - it's their data. 回答1: Look for the line where you do databaseWithPath: (or initWithPath: ), then add: FMDatabase *db = [FMDatabase databaseWithPath:path]; NSDictionary *attributes = @{NSFileProtectionKey

FMDB SQLite question: row count of a query?

由 帅比萌擦擦* 提交于 2019-12-03 05:43:56
问题 does anyone know how to return the count of a query when using FMDB? If I executeQuery @"select count(*) from sometable were..." I get an empty FMResultSet back. How can I get the row count of the query? Do I need to do a query like "select * from sometable where.." and iterate through the result set? Or can I use useCount or whats the best way (in terms of performance) to do this? Thanks! 回答1: Shorter code to accomplish the same thing: NSUInteger count = [db intForQuery:@"SELECT COUNT(field)

问题 I am currently building an app in swift that uses FMDB to interact with a database that is stored on the device.

数据库的使用 总结自： http://www.cnblogs.com/wuhenke/archive/2012/02/07/2341656.html // SQLite的大小写敏感性，不区分带小写。下面的UPDATE 可以写成小写的不过要用双引号引起来。工程里的对比着。 // 直到有一次在網路上發現了FMDB這個東西，才發現不是SQLite很難學，而是SQLite的C API對初學者來說實在太麻煩太瑣碎，難度太高，難怪我怎麼學都學不會。 FMDB說穿了其實只是把C API包裝成簡單易用的Objective-C物件。不過這對我這個SQLite初學者來說，可是大大減低了上手的難度。有了FMDB，寫程式時只要專心在SQLite的語法上，而不用去理那堆有看沒有懂的C API，實在是件快樂的事情。 // 1 打开，关闭资料库 // 使用资料库的第一件事，就是建立一个资料库。要注意的是，在ios环境下，只有document directory是可以进行读写的。在写程序时用的那个Resource资料夹下的东西都是read-only，因此，建立的资料库要放在document资料夹下。 + (void)fun1 { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,
