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

Question

此查詢的正確語法是什麼？

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

或者我應該使用CHARINDEX？

Answer 1

可能

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

Answer 2

我沒有試過，但我認爲這是值得一試：

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

Answer 3

如果你做你的映射（至極的T4將用於做你），那麼你可以INFACT做到這一點，像這樣：

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

節省一些打字:)

Answer 4

可以試試這樣也

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 + "%");
