# NSSQLitePragmasOption

Options key for a dictionary of SQLite pragma settings with pragma values indexed by pragma names as keys.

## Declaration

```swift
let NSSQLitePragmasOption: String
```

## Discussion

Discussion All pragma values must be specified as NSString objects. The fullfsync and synchronous pragmas control the tradeoff between write performance (write to disk speed & cache utilization) and durability (data loss/corruption sensitivity to power interruption). For more information on pragma settings, see http://sqlite.org/pragma.html.
