It does not fix the problem. Am I doing it correctly?
$dbo = $this->getDataSource();
$expression =
$dbo->expression('SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service1\',
ServiceData.stat_value,0)) AS "ServiceData.service1"');
$fields = array('ServiceData.stat_date',
$expression);
$this->find('all', array($fields,...etc, etc.)
Still results in the ugly data.
HOWEVER, I did notice the use of CASE WHEN statements in the test
case. So, I switched my DECODE to CASE WHEN and it works as expected.
I will draw up a test case and report the issue of DECODE failing to
function properly.
Thanks for your help Martin!

Check the text case in this commit for an example:

let me know if that fix the problem, if not, you can prepare a
test case and report the issue.

I don't follow what you mean by "Try using expression for
fields." Can
you clarify or give me an example?

CakePhp is not correctly parsing the alias for the decode
fields, thats
why you see decode... on array keys.
Try using expression for fields. If that works, should
also fix the data
missmatch.

I can read (SELECT) data, but cannot change this
database at all. To
get the data I run the following find:
$this->find('all',
array(
'fields' => array(
'ServiceData.stat_date',
'SUBSTR(ServiceData.stat_parameter,1,4) AS
"ServiceData.schema"',
'SUBSTR(ServiceData.stat_parameter,19,2) AS
"ServiceData.state"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service1\',
ServiceData.stat_value,0)) AS "ServiceData.service1"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service2\',
ServiceData.stat_value,0)) AS "ServiceData.service2"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service3\',
ServiceData.stat_value,0)) AS "ServiceData.service3"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service4\',
ServiceData.stat_value,0)) AS "ServiceData.service4"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service5\',
ServiceData.stat_value,0)) AS "ServiceData.service5"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service6\',
ServiceData.stat_value,0)) AS "ServiceData.service6"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service7\',
ServiceData.stat_value,0)) AS "ServiceData.service7"',
'SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
\'service8\',
ServiceData.stat_value,0)) AS "ServiceData.service8"'
),
'conditions' => array(
'SUBSTR(ServiceData.stat_parameter, 5, 13)' =>
'customer_lookup',
'SUBSTR(ServiceData.stat_parameter, 1, 4)' =>
$active_schema,
'ServiceData.stat_server LIKE' => 'PRODUCTION%',
'ServiceData.stat#' => 999,
'ServiceData.stat_date' => $load_date,
),
'group' => array(
'ServiceData.stat_date',
'SUBSTR(ServiceData.stat_parameter,1,4)',
'SUBSTR(ServiceData.stat_parameter,19,2)'
),
'order' =>
array('SUBSTR(ServiceData.stat_parameter,19,2)')
)
);
This is the resulting query:
SELECT
ServiceData.stat_date
, SUBSTR(ServiceData.stat_parameter,1,4) AS
"ServiceData.schema"
, SUBSTR(ServiceData.stat_parameter,19,2) AS
"ServiceData.state"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service1',
ServiceData.stat_value,0)) AS "ServiceData.service1"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service2',
ServiceData.stat_value,0)) AS "ServiceData.service2"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service3',
ServiceData.stat_value,0)) AS "ServiceData.service3"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service4',
ServiceData.stat_value,0)) AS "ServiceData.service4"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service5',
ServiceData.stat_value,0)) AS "ServiceData.service5"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service6',
ServiceData.stat_value,0)) AS "ServiceData.service6"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service7',
ServiceData.stat_value,0)) AS "ServiceData.service7"
, SUM(DECODE(SUBSTR(ServiceData.stat_parameter,22),
'service8',
ServiceData.stat_value,0)) AS "ServiceData.service8"
FROM
SERVICE_DATA ServiceData
WHERE
SUBSTR(ServiceData.stat_parameter, 5, 13) =
'customer_lookup'
AND SUBSTR(ServiceData.stat_parameter, 1, 4) =
'SCHEMA_A'
AND ServiceData.stat_server LIKE 'PRODUCTION%'
AND ServiceData.stat_number = 999
AND ServiceData.stat_date = TO_DATE('2010-02-17
09:00:02', 'YYYY-MM-
DD HH24:MI:SS')
GROUP BY
ServiceData.stat_date
, SUBSTR(ServiceData.stat_parameter,1,4)
, SUBSTR(ServiceData.stat_parameter,19,2)
ORDER BY
SUBSTR(ServiceData.stat_parameter,19,2) ASC
This results in data returning in this form:
array(43) {
[0]=>
array(3) {
["ServiceData"]=>
array(4) {
["stat_date"]=>
string(19) "2010-02-17 09:00:02"
["schema"]=>
string(4) "SCHEMA_A"
["state"]=>
string(2) "()"
["statvalue"]=>
string(3) "116"
}
["SUM(DECODE(SUBSTR(ServiceData"]=>
array(1) {
["stat_parameter,22)"]=>
string(3) "107"
}
[0]=>
array(3) {
["'service1'"]=>
string(2) "40"
["'service2'"]=>
string(3) "116"
["'service3'"]=>
string(2) "17"
}
}
}
Notice the odd array keys
"SUM(DECODE(SUBSTR(ServiceData" and
"'service1'" (this is the decode value in single
ticks). Also the
value to service1 is the value that belongs in
service2, service2 has
the value for service5, and service3 has the value for
service8???
If I remove the SUM(DECODE(SUBSTR( fields, then
everything works as
expected:
array(43) {
[0]=>
array(1) {
["ServiceData"]=>
array(3) {
["stat_date"]=>
string(19) "2010-02-17 09:00:02"
["schema"]=>
string(4) "SCHEMA_A"
["state"]=>
string(2) "()"
}
}
}
I have tried the afterFind solution posted by TekNoid,
but it did not
work.

Any hints or ideas on how I can overcome the issues of
having such a
complex SUM DECODE of a SUBSTR?
