在sql语句中使用OR的正确方法

Question

我正在使用dapper micro orm与sql server结合使用。

 string author = "some author name";
 var get_book_from_name = "SELECT BookId FROM Author WHERE FirstName OR LastName LIKE('%' +@AuthorName +'%')";
 var data = this.db.Query<Book>(getBookFromAuthorName, new { AuthorName = author }).SingleOrDefault();

我在查询语句中使用OR语句收到错误。

Answer 1

SELECT BookId FROM Author WHERE
    FirstName LIKE '%'+@AuthorName+'%' OR LastName LIKE '%'+@AuthorName+'%'
