协助进行复杂的MySQL SQL查询

Question

I hope this is the appropriate forum to ask for assistance. I have an SQL Query (MySQL) that is not returning the correct records in a Date Range (between two dates). I am happy to answer questions in relation to the query, however if anyone can make suggestions or correct the SQL Query that would be an excellent learning exercise. Thank you.

$raw_query = sprintf("SELECT
swtickets.ticketid AS `Ticket ID`,
swtickettimetracks.tickettimetrackid AS `Track ID`,
swtickets.ticketmaskid AS `TicketMASK`,
(
    SELECT
        swcustomfieldvalues.fieldvalue
    FROM
        swcustomfieldvalues,
        swcustomfields
    WHERE
        swcustomfieldvalues.customfieldid = swcustomfields.customfieldid
    AND swtickets.ticketid = swcustomfieldvalues.typeid
    AND swcustomfields.title = 'Member Company'
    ORDER BY
        swcustomfieldvalues.customfieldvalueid DESC
    LIMIT 1
) AS MemberCompany,
(
    SELECT
        swcustomfieldvalues.fieldvalue
    FROM
        swcustomfieldvalues,
        swcustomfields
    WHERE
        swcustomfieldvalues.customfieldid = swcustomfields.customfieldid
    AND swtickets.ticketid = swcustomfieldvalues.typeid
    AND swcustomfields.title = 'Member Name'
    ORDER BY
        swcustomfieldvalues.customfieldvalueid DESC
    LIMIT 1
) AS MemberName,
(
    SELECT
        swcustomfieldvalues.fieldvalue
    FROM
        swcustomfieldvalues,
        swcustomfields
    WHERE
        swcustomfieldvalues.customfieldid = swcustomfields.customfieldid
    AND swtickets.ticketid = swcustomfieldvalues.typeid
    AND swcustomfields.title = 'Chargeable'
    AND 
        swcustomfieldvalues.fieldvalue = '40'
    ORDER BY
        swcustomfieldvalues.customfieldvalueid ASC
    LIMIT 1
) AS `Chg`,
swtickets.`subject` AS `Subject`,
swtickets.departmenttitle AS Category,
FROM_UNIXTIME(
    swtickettimetracks.workdateline
) AS `workDateline`,
FROM_UNIXTIME(
    swtickettimetracks.dateline
) AS `dateline`,
swtickettimetracks.timespent AS `Time Spent`,
swtickets.timeworked AS `Time Worked`
    FROM
swtickets
    INNER JOIN swusers ON swtickets.userid = swusers.userid
    INNER JOIN swuserorganizations ON swuserorganizations.userorganizationid = swusers.userorganizationid
    INNER JOIN swtickettimetracks ON swtickettimetracks.ticketid = swtickets.ticketid
    WHERE
    swuserorganizations.organizationname = '%s'
    AND (
    swtickets.ticketstatustitle = 'Closed'
OR swtickets.ticketstatustitle = 'Completed'
    )

    AND FROM_UNIXTIME(`workDateline`) >= '%s' AND FROM_UNIXTIME(`workDateline`) <= '%s'

    ORDER BY `Ticket ID`,`Track ID`",
        $userOrganization,
        $startDate,
        $endDate
    );

As I mentioned, the Query works - however it does not return the records correctly between the two dates.

However, IF I run this simple query against the database :

SELECT swtickettimetracks.tickettimetrackid, 
swtickettimetracks.ticketid, 
swtickettimetracks.dateline, 
swtickettimetracks.timespent, 
swtickettimetracks.timebillable,
    FROM_UNIXTIME(swtickettimetracks.workdateline)

    FROM swtickettimetracks

    WHERE FROM_UNIXTIME(swtickettimetracks.workdateline) >= '2013-04-16' AND FROM_UNIXTIME(swtickettimetracks.workdateline) <= '2013-04-18'

I get the correct date range returned. Help? Thank you in anticipation. Edward.

Answer 1

Unless you are overthinking it, it's all in your different query WHERE clauses...

Your complex query returning the wrong results has

  (join conditions between other tables)
  AND swuserorganizations.organizationname = '%s'
  AND ( swtickets.ticketstatustitle = 'Closed'
     OR swtickets.ticketstatustitle = 'Completed' )
  AND FROM_UNIXTIME(`workDateline`) >= '%s' 
  AND FROM_UNIXTIME(`workDateline`) <= '%s'

Your Other query has

FROM swtickettimetracks
WHERE FROM_UNIXTIME(swtickettimetracks.workdateline) >= '2013-04-16' 
  AND FROM_UNIXTIME(swtickettimetracks.workdateline) <= '2013-04-18'

So I would consider a few things. The first where has

FROM_UNIXTIME >= '%s' and FROM_UNIXTIME <= '%s'

Are you sure the '%s' values are properly formatted to match the '2013-04-16' and '2013-04-18' format sample?

But more importantly, your first query is using the same date range (if correct), but is also only getting those for specific organization name AND (Closed or Completed) records. So, if the second query is returning 100 records, but the main query only 70, then are the other 30 some status other than closed/completed, or a different organization? In addition, if the join tables don't have matching IDs that would prevent those with invalid IDs from being returned. The only way to confirm that is to change to LEFT-JOIN syntax on those tables and see the results.
