Instead of NULL how do I show `0` in result with SELECT statement sql?
Use coalesce()
:
select coalesce(Eprice, 0) as Eprice
In SQL Server only, you can save two characters with isnull()
:
select isnull(Eprice, 0) as Eprice
Replacing NULL with 0 in a SQL server query
When you want to replace a possibly null
column with something else, use IsNull.
SELECT ISNULL(myColumn, 0 ) FROM myTable
This will put a 0 in myColumn if it is null in the first place.
Display zero value in field when query output is null
How many flashlights did John Gray buy?
Just use left join
:
SELECT c.[customerid], c.[firstname], c.[lastname],
COALESCE(SUM(cp.quantity), 0)
FROM dbo.customers c LEFT JOIN
dbo.Customer_Purchases cp
ON c.customerid = cp.customerid AND
cp.item = 'flashlight'
WHERE c.customerid = 10101
GROUP BY c.[customerid], c.[firstname], c.[lastname];
Note: You do not want to aggregate by quantity. Presumably, you want to add up all quantities for flashlights. And the filtering on flashlight (but not on customer) needs to be in the ON
clause because the purchases are the second table in the LEFT JOIN
.

How to get NULL or Zero values in SQL Server results set
If I understand correctly, you are looking for OUTER JOIN
, INNER JOIN
will return rows that match between all conditions on two tables.
For this below query RIGHT JOIN
will return rows based on [dbo].[grtbk]
even conditions didn't match, But rows will be NULL
when the row didn't match by the conditions GB.bdr_val
, so we need to use ISNULL
in the aggregate function.
SELECT
SUM(ISNULL(GB.bdr_val,0)) AS Total_Material_M,
GR.oms25_0 AS Desc2,
GR.reknr AS Account
FROM
[dbo].[gbkmut] GB
RIGHT JOIN
[dbo].[grtbk] GR ON GB.reknr = GR.reknr
AND GB.bkjrcode = 2021
AND GB.periode = 11
GROUP BY
GR.oms25_0, GR.reknr
ORDER BY
GR.reknr ASC
