Execute raw SQL using ServiceStack.OrmLite

I am working ServiceStack.OrmLite using MS SQL Server. I would like to execute raw SQL against database but original documentation contains description of how to do it with SELECT statement only. That is not enough for me.

I cant find the way to run anything as simple as that:

UPDATE table1
SET column1 = 'value1'
WHERE column2 = value2

Using, for example:

var two = db.Update(@"UPDATE table1
SET column1 = 'value1'
WHERE column2 = value2");

Running this expressions with db.Update() or db.Update<> produces uncomprehensive errors like

Incorrect syntax near the keyword 'UPDATE'.

I would like to use raw sql because my real UPDATE expression uses JOIN.


db.Update is for updating a model or partial model as shown in OrmLite's Documentation on Update. You can choose to use the loose-typed API to build your update statement, e.g:

db.Update(table: "table1", 
  set: "column1 = {0}".Params("value1"), 
  where: "column2 = {0}".Params("value2"));

The Params extension method escapes your values for you.

Otherwise the way to execute any arbitrary raw sql is to use db.ExecuteSql().
