Insert, Update and Delete

Note: Currently, the following clauses: using, order by, group by, having, join, limit, offset and distinct are totally ignored for the Insert, Update and Delete statements.

Insert

//:playground
var query = new Query("Books").AsInsert(new {
    Title = "Toyota Kata",
    CreatedAt = new DateTime(2009, 8, 4),
    Author = "Mike Rother"
});

INSERT INTO [Books] ([Title], [CreatedAt], [Author]) VALUES ('Toyota Kata', '2009-08-04 00:00:00', 'Mike Rother')

**Note: ** While executing the query you can get the inserted id using the InsertGetId() method

Insert Many

you can use the insert many overload to insert multiple records

//:playground
var cols = new [] {"Name", "Price"};

var data = new [] {
    new object[] { "A", 1000 },
    new object[] { "B", 2000 },
    new object[] { "C", 3000 },
};

var query = new Query("Products")
    .AsInsert(cols, data);

INSERT INTO [Products] ([Name], [Price]) VALUES ("A", 1000), ("B", 2000), ("C", 3000)

Insert from Query

You can also insert records for the result of another Select Query.

//:playground
var cols = new [] { "Id", "Name", "Address" };
new Query("ActiveUsers").AsInsert(cols, new Query("Users").Where("Active", 1));

INSERT INTO [ActiveUsers] ([Id], [Name], [Address]) SELECT * FROM [Users] WHERE [Active] = 1

Update

//:playground
var query = new Query("Posts").WhereNull("AuthorId").AsUpdate(new {
    AuthorId = 10
});

UPDATE [Posts] SET [AuthorId] = 10 WHERE [AuthorId] IS NULL

Delete

//:playground
var query = new Query("Posts").Where("Date", ">", DateTime.UtcNow.AddDays(-30)).AsDelete();

DELETE FROM [Posts] WHERE [Date] > ?
