SQL Help - Incorrect syntax near the keyword 'EXISTS'

Question

I am having issues with my sql (I am relatively new to sql). I cannot figure out why I am getting a syntax error. Any help would be appreciated.

Thanks in advance.

SELECT *
FROM table_name_1
WHERE
column_A IN ('Lorem', 'Ipsum', 'Test') 
AND column_B NOT EXISTS
    (
    SELECT column_C 
    FROM table_name_2
    WHERE Date  >= CURDATE()
    )

Answer 1

You cannot compare NOT EXISTS with a column value.

SELECT *
FROM table_name_1
WHERE
column_A IN ('Lorem', 'Ipsum', 'Test') 
AND NOT EXISTS
    (
    SELECT 1 
    FROM table_name_2
    WHERE Date  >= CURDATE()
    AND column_c = column_b
    )

or use IN

SELECT *
FROM table_name_1
WHERE
column_A IN ('Lorem', 'Ipsum', 'Test') 
AND column_B NOT IN
    (
    SELECT column_C 
    FROM table_name_2
    WHERE Date  >= CURDATE()
    )
