I have this SQL query:
select concept, count(*)
from annotation
where exists (select 1
from annotation a2
where a2.comment_commentid = annotation.comment_commentid and a2.concept = 'Fatigue'
)
group by concept;
And I want to replace 'Fatigue' with {{word}}, to do a filter widget, maping to the column from database.
I have the following error:
ERROR: syntax error at or near "=" Position: 307
What I need to change to aplly the filter? selecting the available words from that column?
With variable type as Text it works... But don't display all the available options, in filter, as variable type Field Filter do...
Thanks!
The outer annotation table needs an alias too. When in doubt, the inner scope always prevails whern resolving names, and the inner exists(...) query an an annotation name in scope, too)
[And the cause of your error is probably that the middleware gets confused]
select concept, count(*)
from annotation a1 -- <<-- HERE!
where exists (select 1
from annotation a2
where a2.comment_commentid = a1.comment_commentid and a2.concept = 'Fatigue'
)
group by concept;

I've the following subquery in an sql query:
(
SELECT ID_PLAN, ID_CURSO, NEDICION, NOMBRE AS NOMBREUNIDAD FROM ASISTEN, ALUMNOS, UNIDADES
WHERE ASISTEN.COD = ALUMNOS.COD AND UNIDADES.IDESTRUCTURA = ALUMNOS.IDESTRUCTURA
AND UNIDADES.CDUNDORG = ALUMNOS.CDUNDORG
AND UPPER(TRANSLATE(UNIDADES.NOMBRE, 'áéíóúÁÉÍÓÚ', 'aeiouAEIOU')) LIKE '%CONSEJERIA%'
GROUP BY ID_PLAN, ID_CURSO, NEDICION) ASIS
Problem I have I believe lies in that both table ALUMNOS and UNIDADES have a column named 'NOMBRE' so if I attempt to execute the query I obtain:
00000 - "column ambiguously defined"
To avoid that I thought about changing NOMBRE AS NOMBREUNIDAD to:
UNIDADES.NOMBRE AS NOMBREUNIDAD
But if I do that I get a:
00000 - "not a GROUP BY expression"
So, I don't know what to do so that subquery executes properly.
What should I change to properly execute query without changing the column name?
Aliases are pretty useful, if you use them. The simplify queries and make them easier to read and maintain. I'd suggest you to do so, as it'll also help query to work because Oracle doesn't know which table you actually meant when you selected those 4 columns - which tables do they belong to?
This is just a guess as I don't know your tables so you'll have to fix it yourself. Also, I literally JOINed tables; try to avoid comma-separating them in FROM clause and doing join in WHERE clause as it is supposed to filter data.
GROUP BY, as already commented, is probably useless. If you wanted to fetch distinct set of values, then use appropriate keyword: distinct.
SELECT DISTINCT n.id_plan,
s.id_curso,
u.nedicion,
u.nombre
FROM asisten n
JOIN alumnos s ON n.cod = s.cod
JOIN unidades u
ON u.idestructura = s.idestructura
AND u.cdundorg = s.cdundorg
WHERE UPPER (TRANSLATE (u.nombre, 'áéíóúÁÉÍÓÚ', 'aeiouAEIOU')) LIKE '%CONSEJERIA%'
I managed to solve my problem:
(
SELECT ID_PLAN, ID_CURSO, NEDICION, UNIDADES.NOMBRE AS NOMBREUNIDAD
FROM ASISTEN, ALUMNOS, UNIDADES
WHERE ASISTEN.COD = ALUMNOS.COD AND UNIDADES.IDESTRUCTURA = ALUMNOS.IDESTRUCTURA
AND UNIDADES.CDUNDORG = ALUMNOS.CDUNDORG
AND UPPER(TRANSLATE(UNIDADES.NOMBRE, 'áéíóúÁÉÍÓÚ', 'aeiouAEIOU')) LIKE '%CONSEJERIA%'
GROUP BY UNIDADES.NOMBRE,ID_PLAN, ID_CURSO, NEDICION
)
I have the following select statement in ABAP:
SELECT munic~mandt VREFER BIS AB ZZELECDATE ZZCERTDATE CONSYEAR ZDIMO ZZONE_M ZZONE_T USAGE_M USAGE_T M2MC M2MT M2RET EXEMPTMCMT EXEMPRET CHARGEMCMT

FROM ZCI00_INSTMUNIC AS MUNIC
INNER JOIN EVER AS EV on
MUNIC~POD = EV~VREFER(9).
"where EV~BSTATUS = '14' or EV~BSTATUS = '32'.
My problem with the above statement is that does not recognize the substring/offset operation on the 'ON' clause. If i remove the '(9) then
it recognizes the field, otherwise it gives error:
Field ev~refer is unknown. It is neither in one of the specified tables
nor defined by a "DATA" statement. I have also tried doing something similar in the 'Where' clause, receiving a similar error:

The basic task i want to implement is to modify a specific field on one table,
pulling values from another. They have a common field ( pod = vrefer(9) ). Thanks in advance for your time.
If you are on a late enough NetWeaver version, it works on 7.51, you can use the OpenSQL function LEFT or SUBSTRING. Your query would look something like:
SELECT munic~mandt VREFER BIS AB ZZELECDATE ZZCERTDATE CONSYEAR ZDIMO ZZONE_M ZZONE_T USAGE_M USAGE_T M2MC M2MT M2RET EXEMPTMCMT EXEMPRET CHARGEMCMT
FROM ZCI00_INSTMUNIC AS MUNIC
INNER JOIN ever AS ev
ON MUNIC~POD EQ LEFT( EV~VREFER, 9 )
INTO corresponding fields of table GT_INSTMUNIC_F.
Note that the INTO clause needs to move to the end of the command as well.
field(9) is a subset operation that is processed by the ABAP environment and can not be translated into a database-level SQL statement (at least not at the moment, but I'd be surprised if it ever will be). Your best bet is either to select the datasets separately and merge them manually (if both are approximately equally large) or pre-select one and use a FAE/IN clause.
They have a common field ( pod = vrefer(9) )
This is a wrong assumption, because they both are not fields, but a field an other thing.
If you really need to do that task through SQL, I'll suggest you to check native SQL sentences like SUBSTRING and check if you can manage to use them within an EXEC_SQL or (better) the CL_SQL* classes.
I am looking to pass declared variables to build my string. I think I want to set my variable via a case expression but I have not done this before. Here is what I have done thus far.
DECLARE #stu_conv AS VARCHAR(5)
-- I think I need a select here.
set #stu_conv = CASE WHEN ITMMASTER.STU_0 ='KG' THEN'2.2'END
SELECT
YPRIMAT.YCROPYR_0
,ITMMASTER.TCLCOD_0
,SPRICLIST.DCGVAL_3
,ITMMASTER.TSICOD_2
,ITMMASTER.ACCCOD_0
,(BASPRI_0*#stu_conv) AS ImportstringAS Importstring
FROM LIVE.YPRIMAT
INNER JOIN LIVE.ITMMASTER ON YPRIMAT.ITMREF_0 = ITMMASTER.ITMREF_0
LEFT OUTER JOIN LIVE.SPRICLIST ON ITMMASTER.TCLCOD_0 = SPRICLIST.PLICRI1_0
WHERE SPRICLIST.PLICRD_0 = 'SPL000020'
I don't see the point for using a variable here, and trying to set it outside the query does not make sense, since you most likely want the value to reset for each row.
I would suggest moving the case expression into the query, as follows:
select
y.ycropyr_0,
i.tclcod_0,
s.dcgval_3,
i.tsicod_2,
i.acccod_0,
baspri_0 * case when i.stu_0 = 'KG' then 2.2 else 1 end as importstringas importstring
from live.yprimat y
inner join live.itmmaster i on y.itmref_0 = i.itmref_0
left outer join live.spriclist s on i.tclcod_0 = s.plicri1_0
where s.plicrd_0 = 'SPL000020'
I assumed that you want a value of 1 when stu_0 is not 'KG', but you can change this as needed.
Side note:
I modified your query to use table aliases. This makes the query shorter to write and somehow easier to read
you would need to prefix column baspri_0 with the table it belongs to (as your query is, it is not possible to tell)
I'm not sure why you're declaring a string and then multiplying it, but I would just inline the case (and add a default case?):
,(BASPRI_0 * CASE
WHEN ITMMASTER.STU_0 ='KG'
THEN 2.2
ELSE ???
END) AS Importstring
I have a Field Field<T>. I want to create a named value for that field, to be able to use it in a query. The name of the value should be the name of the field.
select value as field from ...
Is the the correct way to do it?
public <T> Field<T> namedValue(Field<T> field, T value) {
return DSL.val(value, field).as(field);
}
Although it works, I was wondering if there is a shorter way to do this. I might be pedantic here :).
update
I am creating the following construction:
UPADTE table SET x = alias.x, y = alias.y
FROM (SELECT constant value for x, table2.y FROM table2 WHERE ...) AS alias.
Let's simplify this to (for the sake of this example, to focus on the constant selection):
SELECT
FROM (SELECT constant value for x) AS alias.
First, I started with:
Select s1 = context.select(DSL.val("TEST"));
Select s2 = context.select(s1.fields()).from(s1);
This resulted in an incorrect query:
select "alias_66794930"."TEST" from (select 'TEST') as "alias_66794930"
(I am not really sure if this is correct behavior from jOOQ.)
So, I added an alias:
Select s1 = context.select(DSL.val("TEST").as(X));
Select s2 = context.select(s1.fields()).from(s1);
This resulted in:
select "alias_76324565"."x" from (select 'TEST' as "x") as "alias_76324565"
This works fine. Then, I ran into problems when the constant vale was null:
Select s1 = context.select(DSL.val(null).as(X));
Select s2 = context.select(s1.fields()).from(s1);
This resulted in:
select "alias_85795854"."x" from (select cast(? as varchar) as "x") as "alias_85795854"
1400 [localhost-startStop-1] TRACE org.jooq.impl.DefaultBinding - Binding variable 1 : null (class java.lang.Object)
This makes sense, the field type is not known. So I added the field (with its type) as following:
Select s1 = context.select(DSL.val(null, X).as(X));
Select s2 = context.select(s1.fields()).from(s1);
Binding is now correct:
1678 [localhost-startStop-1] TRACE org.jooq.impl.DefaultBinding - Binding variable 1 : null (class java.lang.String)
All done!
I don't think you can get much shorter than what you already have. I mean, your SQL reads:
value as field
And your Java/jOOQ code reads:
DSL.val(value, field).as(field)
You could of course static import DSL.val or DSL.*:
import static org.jooq.impl.DSL.*;
And then shorten things to:
val(value, field).as(field)
And if you're very sure about value's type, you don't need to coerce it to that of field
val(value).as(field)
Now, you definitely can't go any shorter, and there's no more need for your namedValue() function...

Selecting individual fields like above will give me an "invalid identifier error". If I do select * then it gives me back the data without any error. What am I doing wrong here? Thank you.
The old quoted identifier problem... see point 9 in the database object naming documentation, and note that Oracle does not recommend using quoted identifiers.
You've put your column alias as lower case inside double-quotes. That means that any references to it also have to be quoted and exactly match the case. So this would work:
select
main_data.issue_number,
main_data."transaction_number"
from
...
But unless you have a burning need to have that alias like that - and I doubt you do as all the identifier names from the actual table columns are not quoted - it would be simpler to remove the double quotes from the inner selects:
select
main_data.issue_number,
main_data.transaction_number
from
(
select
...
'' as transaction_number,
p1header.check_account_number
...
UNION ALL
select
...
'' as output_tx_number_prin,
'' as output_tx_number_int,
check.transaction_number,
check.dda_number as check_account_number
...
You don't actually need to alias the columns in the second branch of the union; the column identifiers will all be taken from the first branch.
