Delete from whichever column has the name in it

To fix the issue you can do I have an unassign button and I want to remove the person logged in from whichever column he is in because I have 2 columns and he may be in any of them. , Your delete statement is wrong. It must be:
mysql_query("delete from App where (App.Person1 '" . addslashes(strip_tags($_SESSION["user"])) . "'  OR App.Person2 = '" . addslashes(strip_tags($_SESSION["user"])) . "') and App.ID = '" . addslashes(strip_tags($_SESSION["edit"])) . "'");

Pandas: take whichever column is not NaN

This might help you For a dataframe with an arbitrary number of columns, you can back fill the rows (.bfill(axis=1)) and take the first column (.iloc[:, 0]):
df = pd.DataFrame({
    'A': [15, None, None, None, 12],
    'B': [None, 11, 99, None, 14],
    'C': [10, None, 10, 10, 10]})

df['D'] = df.bfill(axis=1).iloc[:, 0]

>>> df
    A   B   C   D
0  15 NaN  10  15
1 NaN  11 NaN  11
2 NaN  99  10  99
3 NaN NaN  10  10
4  12  14  10  12

How to join with whichever thread finishes first?

I wish did fix the issue. The main thread spawns > 1 threads, and each of them can call return with an error value. If this happens, it is meaningless for the other threads to continue, and so they should be canceled. ,
How to accomplish this?

To fix this issue This will work for you. This is very basic query I wrote. Make changes if required.
SELECT * FROM YOUR_TABLE t 
LEFT OUTER JOIN clients c ON t.client_id = c.id 
LEFT OUTER JOIN notes n ON t.note_id = n.id 
WHERE c.id IS NOT NULL OR n.id IS NOT NULL

How to check if column has value if another column is populated in SQL Server?

I hope this helps you . To directly answer your question I think this is a clean way to get the results you want.
SELECT EffectiveDate,
   Change1,
   Change2,
   Change3 
FROM dbo.Table1
WHERE (EffectiveDate IS NULL AND (Change1 IS NOT NULL OR Change2 IS NOT NULL OR 
Change3 IS NOT NULL))
OR (EffectiveDate IS NOT NULL AND (Change1 IS NULL AND Change2 IS NULL AND Change3 IS 
NULL))
