nhibernate - Join two tables by comparing equal value on two columns -

-

for simplicity , clarity, assume have these 3 tables.

employee [ id ]

employeename [ employeeid, name ]

employeeaddress [ employeeid, address ]

the properties/relationships defined in 'sub-tables' employeename & employeeaddress

  • employeename belongsto employee
  • employeeaddress belongsto employee

there are no properties/relationships (collections) in main employee table such as

  • employee hasmany employeename
  • employee hasmany employeeadress.

i want perform join using detachedcriteria between employeename , employeeaddress only (not involving employee), such

select employeename.name, employeeaddress.address
employeename inner join employeeaddress
employeename.employeeid = employeeaddress.employeeid , employeeaddress.address '%somelocation%' order employeeaddress.address

not query you're looking , haven't tested if works.. may you:

var addresscriteria = detachedcriteria.for<employeeaddress>("ea")                                       .add(restrictions.like("ea.address", "somelocation", matchmode.anywhere)); var namecriteria = detachedcriteria.for<employeename>("en")                                    .add(subqueries.propertyin("en.employee", addresscriteria))                                    .setprojection(projections.property("en.name"));
