I have a search that is very slowly done by finding the primary records

  • 0

I have a search that is very slowly done by finding the primary records then looping in a thread to sum related transactions. I’m trying to make it work in a single statement, have come close but still have records which are alternating debit and credits.

I can’t work out how to pull the debit and credit rows up into columns so there is one row of results per date and jobkey.

SELECT j.dtmInvoicedOn, j.strJobKey, c.strCustName, strTransType,       SUM(r.dblTransactionAmount) AS SUM_dblTotalCharge       FROM tbljobs AS j      INNER JOIN tblreceivledger AS r ON j.strJobKey = r.strJobKey       INNER JOIN tblcustomers AS c ON j.intCustomerID = c.intCustomerID       WHERE c.strCustomerName = 'Acme Runners Inc'      GROUP BY j.strJobKey, c.strCustName, strTransType      ORDER BY dtmInvoicedOn, strJobKey;

produces output like this, with nearly alternating debit and credit sums

+----------------+---------------+------------------+--------------------+--------------------+ | dtmInvoicedOn  | strJobKey     | strCustomerName  | strTransactionType | SUM_dblTotalCharge | +----------------+---------------+------------------+--------------------+--------------------+ | 2008-07-03     | 270876-1      | Acme Runners Inc | credit             |           -5531.52 |  | 2008-07-11     | 270880-1      | Acme Runners Inc | debit              |            5058.54 |  | 2008-07-11     | 270880-1      | Acme Runners Inc | credit             |           -5058.54 |  | 2008-07-18     | 271468-1      | Acme Runners Inc | debit              |            5290.17 |  | 2008-07-18     | 271468-1      | Acme Runners Inc | credit             |           -5290.17 |  | 2008-11-07     | 286049-1      | Acme Runners Inc | debit              |            5230.44 |  | 2008-11-14     | 286051-1      | Acme Runners Inc | debit              |            5375.14 |  | 2008-11-21     | 286107-1      | Acme Runners Inc | debit              |            5572.33 |  | 2008-11-28     | 286112-1      | Acme Runners Inc | debit              |            5123.42 |

so I want it to look like:

+----------------+---------------+------------------+----------+----------+ | dtmInvoicedOn  | strJobKey     | strCustomerName  |   credit |    debit | +----------------+---------------+------------------+----------+----------+ | 2008-07-03     | 270876-1      | Acme Runners Inc | -5531.52 |        0 | | 2008-07-11     | 270880-1      | Acme Runners Inc | -5058.54 |  5058.54 |  | 2008-07-18     | 271468-1      | Acme Runners Inc | -5290.17 |  5290.17 |  | 2008-11-07     | 286049-1      | Acme Runners Inc |        0 |  5230.44 |  | 2008-11-14     | 286051-1      | Acme Runners Inc |        0 |  5375.14 |  | 2008-11-21     | 286107-1      | Acme Runners Inc |        0 |  5572.33 |  | 2008-11-28     | 286112-1      | Acme Runners Inc          0 |  5123.42 |

Note that the server is currently running mysql but will migrate to postgres and sqlite later.

thanks

  1. this should do the job:

    SELECT j.dtmInvoicedOn, j.strJobKey, c.strCustName, strTransType,       SUM(CASE WHEN strTransType='credit' THEN r.dblTransactionAmount ELSE 0 END) AS SUM_CREDIT,      SUM(CASE WHEN strTransType='debit' THEN r.dblTransactionAmount ELSE 0 END) AS SUM_DEBIT FROM tbljobs AS j      INNER JOIN tblreceivledger AS r ON j.strJobKey = r.strJobKey       INNER JOIN tblcustomers AS c ON j.intCustomerID = c.intCustomerID  WHERE c.strCustomerName = 'Acme Runners Inc' GROUP BY j.strJobKey, c.strCustName ORDER BY dtmInvoicedOn, strJobKey;
