Formatting a MySQL Query result -


i've got table follows,

column      type time        datetime              ticket      int(20)               agentid     int(20)               exitstatus  varchar(50)       queue       varchar(50)

i want write query break down week, providing column count each exitstatus. far have this,

select exitstatus,count(exitstatus) exitstatuscount, day(time) timeperiod  `table`  group timeperiod, exitstatus

output:

exitstatus exitstatuscount timeperiod noagentid                1          4  success                  3          4 noagentid                1          5 success                  5          5

i want change returns results in format:

week | count(noagentid) | count(success) |

ideally, i'd columns dynamic other exitstatus values may possible.

this information formatted , presented end user in table on page. can done in sql or should reformat in php?

there no "general" solution problem (called cross tabulation) can achieved single query. there 4 possible solutions:

  • hardcode possible exitstatus'es in query , keep updated see need more , more of them. example:
select     day(time) timeperiod,     sum(if(exitstatus = 'noagentid', 1, 0)) noagentid,     sum(if(exitstatus = 'success', 1, 0)) success     -- #todo: add others here when/if needed table ... group timeperiod

  • do first query possible exitstatus'es , create final query high-level programming language based on results.

  • use special module cross tabulation on high-level programming language. perl, have sqlcrosstab module couldn't find 1 php

  • add layer application using olap (multi-dimensional views of data) pentaho , querying layer instead of original data

you can read lot more these solutions , overall discussion of subject
