Question

I have a table in SQL Server that contains the following columns :

Id  Name     ParentId  LevelOrder
8   vehicle  0         0/8/
9   car      8         0/8/9/
10  bike     8         0/8/10/
11  House    0         0/11/ 
...

This creates a tree.

Say that I have the LevelOrder 0/8/, this should return only the car and bike rows, but how do I handle this in SQL Server?

I have tried :

Select * FROM MyTable WHERE LevelOrder >= '0/8/' 

but that does not work.

Answer 1

The underscore character will guarantee at least one character comes after ‘0/8/’, so you don’t get a match on the “vehicle” row.

SELECT *
    FROM MyTable
    WHERE LevelOrder LIKE '0/8/_%'
