Question

I have an SQL query that groups by transaction type and then sums amount, but would like the summed amount to be in a column for each transaction type

i have this:

select Job, 
       sum(amount) as Amount, 
       transaction_type 
 from JCT_CURRENT__TRANSACTION
WHERE transaction_date >= {?Start Date} 
  and transaction_date <= {?End Date}
GROUP BY Job, transaction_type
ORDER BY Job ASC

But would like:

Job  | TransType1AmountSum  | TransType2AmountSum  |  TransType3AmountSum

so i would only have one line per job.

Use:

  SELECT t.job,
         SUM(CASE WHEN t.transaction_type = 'TransType1' THEN t.amount ELSE NULL END) AS TransType1AmountSum,
         SUM(CASE WHEN t.transaction_type = 'TransType2' THEN t.amount ELSE NULL END) AS TransType2AmountSum,
         SUM(CASE WHEN t.transaction_type = 'TransType3' THEN t.amount ELSE NULL END) AS TransType3AmountSum
    FROM JCT_CURRENT_TRANSACTION t
   WHERE transaction_date BETWEEN {?Start Date} 
                              AND {?End Date}
GROUP BY t.job
