Question

I am working with the statistician at my company and trying to connect to a mysql database from WPS (world programming system). The WPS docs are pretty terrible.

i tried this sas/access approach:

func clearCache() {
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let fetchRequest = NSFetchRequest()
fetchRequest.entity = NSEntityDescription.entityForName("CacheItems", inManagedObjectContext: managedObjectContext)
fetchRequest.includesPropertyValues = false

do {
    let results = try managedObjectContext.executeFetchRequest(fetchRequest) as! [NSManagedObject]
    for result in results {
        managedObjectContext.deleteObject(result)
    }

} catch {
    let nserror = error as NSError
    NSLog("CoreData erasing error - \(nserror), \(nserror.userInfo)")
}

// checking Cache items count
do {
    let fetchRequest = NSFetchRequest(entityName: "CacheItems")
    myCacheItems = try managedObjectContext.executeFetchRequest(fetchRequest) as! [CacheItemsClass]
} catch let error as NSError {
    print("\(error.localizedDescription)")
} }

however, i got the error:

could not load module MYSQL or one of it's dependencies. etc. etc.

Is there something specific configuration wise that you have to do to use MYSQL with WPS?

对于任何试图解决此问题的人来说，这是我在Linux中的解决方案以及我是如何找到它的。

mysql引擎是以下模块：“libwpsemsql.so”要查看缺少的内容，可以键入：

ldd /yourfolder/wpl/wps-3.3/bin/libwpsemsql.so

您会注意到未解决的链接条目。如下定义LD_LIBRARY_PATH并将其放在您的配置文件或/etc/profile.d/wps.sh中作为示例。

export LD_LIBRARY_PATH = / yourfolder / wpl / wps-3.3 / bin

接下来你会看到缺少所以实际上是libmysql.so.16。我不知道他们从最初选择了什么，但是我找到了https://github.com/janzhou/js-c的工作副本，其工作方式是输入以下内容：

更改为您的wps安装文件夹
cd /yourfolder/wps-3.3/bin
wget https://github.com/janzhou/js-c/raw/master/mysql/linux-x86-64bit/lib/libmysql.so.16.0.0
ln -s libmysql.so.16.0.0 libmysql.so.16

那应该是它！这也是挖掘任何缺失依赖性的有用技术。在Windows中，您可以查看您的wps安装文件夹，并在第174页上找到标题为“连接到MySQL数据库”的WPS Workbench用户指南，它引用了如何下载Connector / C并在Windows中安装。我在Linux中尝试了相同的技术，但它导致了libmysqlclient.so.18.6，当我尝试使用它时，wps段出现故障。
