I'm using Fluent Nhibernate (v2.1.2) with MySQL (v8) in a .net core project. After mapping my class using HasMay in one of the class property I'm getting this error
NHibernate.Exceptions.GenericADOException: could not execute query [select (...Some selects here like "item1_.ItemId as col_0_0_") from Cart cart0_ left outer join Item item1_ on cart0_.CartId = item1_.CartId where cart0_.CartId in ( select cart2_.CartId from Cart cart2_ where? p0 = 1 or cart2_.Description like concat('%',? p1,'%')limit? p2,? p3)] Name : p1 - Value : True Name : p2 - Value : null Name : p3 - Value : 0 Name : p4 - Value : 100 [SQL: select (...) from Cart cart0_ left outer join Item item1_ on cart0_.CartId = item1_.CartId where cart0_.CartId in ( select cart2_.CartId from Cart cart2_ where? p0 = 1 or cart2_.Description like concat('%',? p1,'%')limit? p2,? p3)] -- -> MySql.Data.MySqlClient.MySqlException(0x80004005): This version of MySQL doesn 't yet support ' LIMIT & IN / ALL / ANY / SOME subquery '
Here is my class-map:
public class CartMap : ClassMap<Cart>
{
public CartMap()
{
Table("Cart");
Not.LazyLoad();
Id(x => x.Id).Column("CartId");
// (...other properties)
HasMany(x => x.Item).Table("Item").KeyColumn("CartId").Cascade.None();
}
}
My tables are like:
TABLE Cart
CartId int(11) PRIMARY KEY AUTO_INCREMENT,
Description varchar(500),
(... other columns)
TABLE Item (
ItemId int(11) PRIMARY KEY AUTO_INCREMENT,
CartId int(11)
(... other columns)
I think is because the Nhibernate is using "limit" to do the select, any other ways to get the same result?
