Issue:

How to sum the amount in one column?

Solution:

Inside SSMS enter this, to sum column [amount] all rows that have active=”y’ and date = 20221201.

SELECT SUM(amount)
FROM [DM].[table1]
where [Active] = 'Y'
and [sDate] = '20221201'

 

To list all rows from two identical tables, including duplicates enter:

SELECT column_name(s) FROM table1
UNION ALL
SELECT column_name(s) FROM table2

 

List number of rows from a table, from a selection:

select count(*)
FROM [DM].[table1] WHERE [Active] = 'Y'

 

How copy a number of rows into a new table:

SELECT *
INTO [DM].[table1]
FROM [DM].[table2]
WHERE [active] = 'N';
