SQL query to find record with ID not in another table

Question

I have two tables with binding primary key in database and I desire to find a disjoint set between them. For example,

• Table1 has columns (ID

Answer 1

Keeping in mind the points made in @John Woo's comment/link above, this is how I typically would handle it:

SELECT t1.ID, t1.Name 
FROM   Table1 t1
WHERE  NOT EXISTS (
    SELECT TOP 1 NULL
    FROM Table2 t2
    WHERE t1.ID = t2.ID
)
