Create a query for SQL Server into multiple tables and order the result in the form of the tree relationship
I have 3 tables:
1) id1, name
2) id2,name,id1
3) id3,name,i开发者_如何学God2
I'm looking for help to compose a query for SQL Server that will return a result ordered in form of an expanded tree - like:
t1.id1
t2.id2
t3.id3
t3.id3
t3.id3
t2.id2
t3.id3
...
All id
fields are unique identifiers, so in result table I want to get just 2 fields - ID,Name
Standard SQL can not do that. You can't return a tree in that way - all rows are similar, meaning the column in each row comes from the same table.
You could however program something to do that.
