PetaPoco：如何使用SQL Like关键字（WHERE Name LIKE'％@ 0％'）

Question

此查询的正确语法是什么？

var l=db.Fetch<article>("SELECT * FROM articles WHERE title LIKE '%@0%'", 'something'); 

或者我应该使用CHARINDEX？

Answer 1

可能

var l=db.Fetch<article>("SELECT * FROM articles WHERE title LIKE @0", "%something%");

Answer 2

我没有试过，但我认为这是值得一试：

var l=db.Fetch<article>("SELECT * FROM articles WHERE title LIKE @0", "%" + "something" + "%"); 

Answer 3

如果你做你的映射（至极的T4将用于做你），那么你可以INFACT做到这一点，像这样：

var l=db.Fetch<article>("WHERE title LIKE @0", "%something%"); 

节省一些打字:)

Answer 4

可以试试这样也

var l=db.Fetch<article>("WHERE title LIKE @0", "%" + "something" + "%"); 

Answer 5

Articulo articulo = new Articulo(); 

articulo = db.SingleOrDefault<Articulo>("SELECT TOP (1) * FROM [Articulos] WHERE [CodigoEmpresa] = @0 and [CodigoArticulo] LIKE @1 ", CodigoEmpresa, codigoArticulo + "%");
