petapoco - 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');

还是我应该使用CHARINDEX？

Answer 1

或许

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

Answer 2

我没有尝试过，但我认为值得尝试：

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

Answer 3

如果您已经完成了映射（T4 将为您完成），那么您实际上可以这样做：

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

节省一些打字:)

Answer 4

也可以这样试试

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 + "%");
