How to use PIVOT in SQL for this sample - sql

Question

How do I pivot a results query?
Currently it looks like this
| Date | Count | BankName |
+---------+----------+----------+
| 970401 | 87 | Saderat |
| 970401 | 25 | Melli |
| 970401 | 11 | Sina |
into this
|Date | Saderat | Melli | Sina |
+---------+----------+----------+----------+
|970401 | 87 | 25 | 11 |
I tried the following but it's not working
SELECT
PayDate AS [Date],
COUNT(*) AS [Count], b.BankName
FROM
Payments p
INNER JOIN
dbo.Accounts a ON a.AccountId = p.CashAccountId
INNER JOIN
dbo.Banks b ON b.BankId = a.BankId
WHERE
PayTypeId = 21.101
AND PayDate BETWEEN '970401' AND '970412'
GROUP BY
PayDate, b.BankName
ORDER BY
paydate
or
SELECT
x.PayDate AS 'Date',
b.BankName
FROM
(SELECT
p.PayDate, p.PaymentId, p.CashAccountId
FROM
Payments p
WHERE
PayTypeId = 21.101
AND PayDate BETWEEN '970401' AND '970412') AS x
INNER JOIN
dbo.Accounts a ON a.AccountId = x.CashAccountId
INNER JOIN
dbo.Banks b ON b.BankId = a.BankId
PIVOT
(COUNT(PaymentId) FOR PayDate IN (bankid)) AS Pivotable

Answer 1

You can try following SQL for required results:
SELECT PayDate, Saderat, Melli, Sina
FROM
(SELECT PayDate , COUNT(*) AS [Count] , b.BankName
FROM Payments p INNER JOIN dbo.Accounts a ON a.AccountId = p.CashAccountId
INNER JOIN dbo.Banks b ON b.BankId = a.BankId
WHERE PayTypeId = 21.101 AND PayDate BETWEEN '970401' AND '970412'
GROUP BY PayDate , b.BankName
ORDER BY paydate) AS SourceTable
PIVOT
(
SUM([Count])
FOR BankName IN (Saderat, Melli, Sina)
) AS PivotTable;

Answer 2

You can do aggregation :
SELECT PayDate AS [Date],
SUM(CASE WHEN b.BankName = 'Saderat' THEN 1 ELSE 0 END) AS Saderat,
. . .
FROM Payments p INNER JOIN
dbo.Accounts a
ON a.AccountId = p.CashAccountId INNER JOIN
dbo.Banks b
ON b.BankId = a.BankId
WHERE PayTypeId = 21.101 AND PayDate BETWEEN '970401' AND '970412'
GROUP BY PayDate
ORDER BY paydate;

Answer 3

You can use PIVOT function in SQL Server, try following query:
SELECT date, [Saderat],[Melli],[Sina]
FROM YourTableName
PIVOT( MAX(count)
FOR BankName IN ([Saderat],[Melli],[Sina])) AS p

Answer 4

You could PIVOT
SELECT *
FROM
(
SELECT
p.PayDate AS [Date],
b.BankName
FROM dbo.Payments p
JOIN dbo.Accounts a ON a.AccountId = p.CashAccountId
JOIN dbo.Banks b ON b.BankId = a.BankId
WHERE p.PayTypeId = 21.101
AND p.PayDate BETWEEN CAST('1997-04-01' AS DATE) AND CAST('1997-04-12' AS DATE)
) src
PIVOT
(
COUNT(*)
FOR BankName IN (...) -- put quoted list of bank names here
) pvt
ORDER BY [Date]
