I want to find if the difference between 2 columns. How do I achieve that?
For example,
select(col1-col2) output is 1
select(col2-col1) output is -1
Is there a way to get just the difference as 1 without the negative (-) sign?
use abs() function
select abs(col2-col1) as diff

How can I find data that dont end with letter 'g' without using NOT LIKE function, please help
select * from table where right(column, 1) != 'g'
Since you asked how to do it using "not like," I'll answer that. The function version provided by #Zoories would be more efficient.
This works at w3schools.com
SELECT * FROM Customers where CustomerName not like '%g';

I need to convert "2022-04-29T07:20:32.727Z" to "2022-04-29 07:20:32".
I am quite new to SQL and haven't found the solution.
You can use cast()
select cast('2022-04-29T07:20:32.727Z' as datetime)
Output
2022-04-29 07:20:32.727

Team,
I need a sql query or function which will create the mirror image of string.
Thanks
Rajeev
If "mirror" is reversed text use:
SELECT REVERSE('my_text') FROM dual;
EDIT:
SqlFiddleDemo
SELECT t
,REVERSE(t) AS Mirror1
,TRANSLATE(t, 'abcdefghijklmnopqrstuvwxyz',N'ɐqɔpǝɟbɥıظʞןɯuodbɹsʇnʌʍxʎz') AS Mirror2
,TRANSLATE(REVERSE(t), 'abcdefghijklmnopqrstuvwxyz',N'ɐqɔpǝɟbɥıظʞןɯuodbɹsʇnʌʍxʎz') AS Mirror3
FROM tab;

I am using Oracle SQL developer 2012. My data looks like 'valueA-valueB'. I want to strip the content after - and populate with rest.
You can use a combination of substr and instr:
SELECT SUBSTR(my_column, 1, INSTR(my_column, '-') - 1)
FROM my_table
