In my model I wrote:
$criteria->select = ' ( select avg( IfNULL( TR.stars_rating_type_id , 0) ) as stars_rating_type_id from '.$tablePrefix.'tour_review as TR where TR.tour_id = T.id and TR.status = \'A\' ) as reviews_avg_rating ';
And I get error :
Active record "Tour" is trying to select an invalid column "( select
avg( IfNULL( TR.stars_rating_type_id". Note, the column must exist in
the table or be an expression with alias.
The reason is that I add "IfNULL( ..., 0)" function in subquery to escape "null" in result set.
Without it I have to make additional verification and set 0 in case of null.
If I test raw sql with " SELECT ( select avg( IfNULL( TR.stars_rating_type_id, 0) ) as stars_rating_type_id..." it works ok,
so that is the problem from the yii side. How to fix it ?
Yii 1.1.14
Thanks!
Take a look on the manual:
http://www.yiiframework.com/doc/api/1.1/CDbCriteria
the select param receive the columns that will be search, not the hole query

I have the script below setup in AWS Athena, the goal is to replace some budget numbers (total) with 0 if they are within a certain category (costitemid). I'm getting the following error in AWS Athena and could use some advice as to why it isn't working. Is the problem that I need to repeat everything in the FROM and GROUP BY in the WHEN and ELSE? Code below the error. Thank you!

Your syntax is wrong (at least according to most SQL dialects.) You can't generally say "SELECT CASE WHEN (condition) THEN (this select clause) ELSE (that select clause) END FROM (tables)"
You can only use CASE to calculate a single value.
But it looks as if the only change between your two inner SELECT clauses is whether you use 0 or the quantity in the final multiplication. And that is perfect for a CASE!
I do not guarantee this will work right off the bat, because I don't have your setup or an idea of your table layout. However, it's a step in the right direction:
SELECT
projectbudgets.projectid
, projectbudgetyears.year fiscalYear
, projectbudgetyears.status
, "sum"(
((
CASE
WHEN projectbudgetlineitems.costitemid IN (462561,462562,462563,462564,462565,462566,478030)
THEN 0
ELSE projectbudgetlineitems.quantity
END * projectbudgetlineitems.unitcost
) * (
projectbudgetlineitems.costshare * 1E-2
))) total
FROM
(("acorn-prod-etl".target_acorn_prod_acorn_projectbudgets projectbudgets

"acorn-prod-etl".target_acorn_prod_acorn_projectbudgetyears projectbudgetyears

INNER JOIN "acorn-prod-etl".target_acorn_prod_acorn_projectbudgetlineitems projectbudgetlineitems
ON (projectbudgetyears.id = projectbudgetlineitems.projectbudgetyearid))
GROUP BY
projectbudgets.projectid, projectbudgetyears.year, projectbudgetyears.status
This could solve your problem if you want to sum the items for each project and year and status except for certain line items. Here, it is correct to use a "where" condition and not "case when" :
SELECT
projectbudgets.projectid,
projectbudgetyears.year,
projectbudgetyears.status,
"sum"(((projectbudgetlineitems.quantity * projectbudgetlineitems.unitcost) *
(projectbudgetlineitems.costshare * 1E-2))) total
FROM
(("acorn-prod-etl".target_acorn_prod_acorn_projectbudgets projectbudgets
INNER JOIN "acorn-prod-etl".target_acorn_prod_acorn_projectbudgetyears
projectbudgetyears ON (projectbudgets.id = projectbudgetyears.projectbudgetid))
INNER JOIN "acorn-prod-etl".target_acorn_prod_acorn_projectbudgetlineitems
projectbudgetlineitems ON (projectbudgetyears.id =
projectbudgetlineitems.projectbudgetyearid))
WHERE projectbudgetlineitems.costitemid NOT IN
(462561,462562,462563,462564,462565,462566,478030)
GROUP BY projectbudgets.projectid, projectbudgetyears.year,

I have the following code in Oracle 11:
select xmlelement("foo", xmlagg(xmlelement("bar",myValues))) from someTable where rownum = 0; --Changing the rownum from 0 should give me values
The output currently is: <foo></foo>
I would instead like this to return nothing, or null, when no rows are select. Otherwise it'll be a XMLtype with the aggregated data like how I have it above.
How would I be able to achieve this for the case when no rows are selected?
You can use case select:
select case when count (*) != 0 then xmlelement("foo", xmlagg(xmlelement("bar",myValues))) end
You can convert to CLOB using getClobval function and do a comparison.
SELECT
xml
FROM
(
SELECT
xmlelement("foo",xmlagg(xmlelement("bar",myvalues) ) ).getclobval() xml
FROM
sometable
)
WHERE
TO_CHAR(xml) != '<foo></foo>';
I am working on a query that devide 2 columns, I tried CAST and CONVERT but still returns 0. Will apperciate your help
SELECT a.Disposition,a.[Disposition Reason Breakdown],a.CSP,b.Total FROM
(
SELECT a.[Disposition],a.[Disposition Reason Breakdown],a.[CSP] FROM
(
SELECT [Disposition],[Disposition Reason Breakdown],COUNT(*) as CSP FROM [dbo].[Disposition]
WHERE [Disposition] <> 'Interested'
GROUP BY [Disposition],[Disposition Reason Breakdown]
) a
)a
INNER JOIN
(
SELECT a.Disposition,SUM(a.CSP) as Total FROM
(
SELECT [Disposition],[Disposition Reason Breakdown],COUNT(*) as CSP FROM [dbo].[Disposition]
WHERE [Disposition] <> 'Interested'
GROUP BY [Disposition],[Disposition Reason Breakdown]
)a
GROUP BY a.Disposition
)b ON a.Disposition = b.Disposition
I am using sql
I solved it, it turns out that I just used the wrong data type which in my case is decimal I should've thought of REAL here is the final query a.CSP/CAST(b.Total as REAL)
I am trying to to run a query like the one below. The goal is to get the total activity count for every user_key but because the user_key has a complex structure and I need only the part after the '|' symbol I had to use a substring function. However, when I'm trying to run the query, I get the
error:
SQL Error [42Y36]: Column reference 'USER_KEY' is invalid, or is part of an invalid expression. For a SELECT list with a GROUP BY, the columns and expressions being selected may only contain valid grouping expressions and valid aggregate expressions.
The substring function works OK outside this query. Any workarounds for this problem? Using Splice Machine (NoSql)
SELECT
substr(user_key, instr(user_key,'|') + 1) AS new_user_key,
SUM(
CAST(
activity_count AS INTEGER
)
) AS Total
FROM
schema_name.table_name
GROUP BY
substr(user_key, instr(user_key,'|') + 1)
Your GROUP BY column needs to match the SELECT
SELECT
substr(user_key, instr(user_key,'|') + 1) AS new_user_key,
SUM(
CAST(
activity_count AS INTEGER
)
) AS Total
FROM
schema_name.table_name
GROUP BY
substr(user_key, instr(user_key,'|') + 1) AS new_user_key
I found the answer myself. I used a table subquery:
SELECT new_table.new_user_key, sum(new_table.total)
from
(
SELECT
substr(user_key, instr(user_key,'|') + 1) AS new_user_key,
CAST(activity_count AS INTEGER) AS Total
FROM schema_name.table_name
)
as new_table
GROUP BY
new_table.new_user_key
Let's hope someone will find this post useful and will save some time to him or her.
I have a DECODE in my WHERE clause like this:
Where id = decode('&flag','Yes',(Select id from tab where id > 10),0)
This code works if the subquery returns one post. If I returns several I get an error like, ORA-01427, "Single-row subquery returns more than one row"
I've tried to change the '=' to an 'in' but I still get the same error!
Any ideas?
extended example:
WHERE Dop_id = (DECODE ('&prep_flag', 'Yes',
(SELECT Dop_id FROM
( SELECT DOP_id, name FROM TABLE)
WHERE name IS NOT NULL)
, Dop_id))
as mention this works if the select statmen returns on row, and not several.
Assuming decode is only expecting a single value where you have Select id from tab where id > 10 I would try moving the select outside of decode:
WHERE id IN (
SELECT decode('&flag', 'Yes', id, 0)
FROM tab
WHERE id > 10
)
WHERE Dop_id IN
( CASE &flag
WHEN 'Yes'
THEN (SELECT Dop_id
FROM TABLE
WHERE name IS NOT NULL)
ELSE Dop_id);
