Question

The existing code I’m trying to modify goes something like:

SELECT * FROM <table1>
JOIN
( SELECT * FROM <table2>
    WHERE GETDATE() BETWEEN <fields from table2> )

I need to change the GETDATE() to reference a field from table1

I’d prefer to make the changes as small and local as possible as to not cause issues elsewhere so I’m hoping there’s some simple way I can reference the current values from the initial SELECT.

Answer 1

Give the table an alias and you can refer to it in sub queries using that subquery.

Though you should be able to just use joins:

SELECT * FROM <table1> 
INNER JOIN <table2>
    ON <table1>.DateField BETWEEN <fields from table2>
