## Installation

`atlas use sqliteral`

## 4.0.0 Release notes (2023-08-19)

* Compatibility with Nim 2

* Single-threaded mode is not supported anymore (breaking change)

* Avoid crashing from trying to get filesize of in-memory database in about

* Unlimited amount of threads supported

* New finalizeStatements proc (semi-breaking change)

* New interrupt proc

* Various minor performance and other fixes

## Example

```nim

import sqliteral

const Schema = "CREATE TABLE IF NOT EXISTS Example(string TEXT NOT NULL)"

type SqlStatements = enum

  Upsert = """INSERT INTO Example(rowid, string) VALUES(1, ?)

   ON CONFLICT(rowid) DO UPDATE SET string = ?"""

  SelectAll = "SELECT string FROM Example"

var db: SQLiteral

proc operate(i: string) =

  let view: DbValue = i.toDb(3, 7) # zero-copy view into string

  db.transaction: db.exec(Upsert, view, view)

  for row in db.rows(SelectAll): echo row.getCString(0)

db.openDatabase("example.db", Schema)

db.prepareStatements(SqlStatements)

var input = "012INPUT89"

operate(input)

db.close()

```
