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

可能是

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

Answer 2

我没试过，但我认为值得尝试：

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

Answer 3

如果你已经完成了你的映射（T4会为你做什么）那么你可以这样做：

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

保存一些输入：）

Answer 4

也可以尝试这样

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 + "%");
