在使用 Entity Framework Core (EF Core) 的 Code First 模式时,如果你想在 SQLite 数据库中存储 JsonDocument or DateTime 类型的数据,需要确保数据类型的正确映射。 注意: - `SQLite` 默认没有 `JsonDocument` 类型,而是使用 `json` 或 `TEXT` 类型来存储 `JSON` 值。 - `SQLite` 默认没有一个单独的用...

因为要使用到了CodeFirst了,所以我们必须要对我们的实体类 Model 进行配置,当然也有很多的小伙伴,使用的是EFCore,当然是可以的,EFCore不需要对实体类进行处理,只是需要额外的配置上下文和Map映射,比如这样: EFCore的我就不多少了,很简单,如果有不会的小伙伴,可以看我的第二个系列的《让你明白DDD的小故事 & EF...
// 调用SQlite API时,如果成功则会返回SQLITE_OK,如果调用失败将返回一个错误码(Error code),指明发生了什么错误。对API调用的返回值进行适当检查,可以提高程序的健壮性。NSInteger status=sqlite3_open_v2([self databasePath],&_pDB,SQLITE_OPEN_READWRITE|SQLITE_OPEN_CREATE,NULL);/* sqlite3_open_v2(...

Platform-Specific Code: Supplying the Connection String As with any kind of database, your code accesses a SQLite database through the connection string, which is the first thing you need to build. Because a SQLite database is a file that resides in a local folder, constructing the connection...
