In my code, I would like to filter using WHERE
SELECT * FROM myView view WHERE view.order_no = ?
but Java/PostgreSQL give error:
ERROR: column view.order_no does not exist
Please help as this is quite complicated as it involves multiple tables and a lot of columns. I am not sure why view.order_no does not exist because it is selected in col_5_0
You can reference the view by its name:
SELECT * FROM myView WHERE id = ?
Also view is a keyword in sql.
You have renamed the column order_no as col_5_0_. So you need to use that:
SELECT *
FROM myView v
WHERE v.col_5_0_ = ?;
That is, you can only reference the columns that are returned by the view.
Renaming columns to meaningless strings seems like a really bad idea -- at least if the views are exposed to human beings. It is not clear to me why anyone would want to obfuscate them.
Also, don't use view as a table alias (or any other identifier). It is a SQL keyword, and it is best to avoid those as identifiers.
Create your view like this way and use view reference in where clause
CREATE VIEW view_name
AS
SELECT column1, column2, ...
FROM table_name
WHERE condition;
You can also filter rows during view creation.
SELECT *
FROM view_name
WHERE view_name.col_name = ?

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 view:
SELECT MIN(v.DOBA_VYSETRENI), v.ID_PACIENTA, v.ID_DOKTORA, d.MIN_DOBA
FROM vysetreni v,
doktor d
WHERE v.ID_DOKTORA = d.ID_DOKTORA
AND v.ID_VYSETRENI = 1
GROUP BY v.ID_DOKTORA, v.ID_PACIENTA, d.MIN_DOBA;
I can call view using:
select * from pohled;
It possible set some parameter (v.ID_VYSETRENI)?
Some like this:
select * from pohled WHERE v.ID_VYSETRENI = 2;
Thank you for your help
ID_VYSETRENI is not declared in your view specification, so add the field to the view specification, something like:
SELECT MIN(v.DOBA_VYSETRENI), v.ID_PACIENTA, v.ID_DOKTORA, d.MIN_DOBA, v.ID_VYSETRENI
FROM vysetreni v, doktor d
WHERE v.ID_DOKTORA = d.ID_DOKTORA
AND v.ID_VYSETRENI = 1
GROUP BY v.ID_DOKTORA, v.ID_PACIENTA, d.MIN_DOBA, v.ID_VYSETRENI;
And then you will be able to reference it when you query your view.
select * from pohled WHERE ID_VYSETRENI = 2;
Note that I included your field in your GROUP clause, however, as you may know already, could use MAX or MIN, you should know better the logic of your desired resulting data set to include the column, so I leave that to you.
And BTW OldProgrammer is right this should be tagged as SQL only.
Sorry for the long title.
I have a statement which needs to grab all the columns from one row from BinConfig:
SELECT *
FROM BinConfig WITH(NOLOCK)
WHERE IssuerKey = #IssuerKey
But I also need to grab a single column from one row from CardRangeGroup also based on that IssuerKey column.
What I've tried:
SELECT
BinConfig.*, CardRangeGroup.Name
FROM
BinConfig
JOIN
CardRangeGroup WITH(NOLOCK)
WHERE
#IssuerKey = BinConfig.IssuerKey
AND #IssuerKey = CardRangeGroup.IssuerKey
Which gives me a syntax error near WHERE. I've tried to find resources online, but everywhere I look I can't find anything explaining how to select rows based on a passed in variable. Any help?
You need to specify how the tables should be joined. Try this:
SELECT BinConfig.*, CardRangeGroup.Name
FROM BinConfig
JOIN CardRangeGroup ON BinConfig.IssuerKey = CardRangeGroup.IssuerKey
WHERE #IssuerKey = CardRangeGroup.IssuerKey
The with(nolock) might not be needed (or a good idea) so I removed it.
try this , you don't need to use where
SELECT BinConfig.*, CardRangeGroup.Name FROM BinConfig JOIN
CardRangeGroup
ON CardRangeGroup.IssuerKey = BinConfig.IssuerKey AND #IssuerKey = CardRangeGroup.IssuerKey
I want to incorporate a new column into a working SQL query.
However, it causes the whole query return nothing at all(because the column is mostly null in the database) .
Here's my pared-down code so far :
SELECT DISTINCT submittedRow.PERFORMED_DATE as "submitted",
supervisorRow.PERFORMED_DATE as "superv",
/* coalesce(sodRow.PERFORMED_DATE, TO_DATE('2000/07/07', 'YYYY/MM/DD') ) */ null AS "SOD"
hhs_umx_resp_activity submittedRow
join hhs_umx_resp_activity supervisorRow ON supervisorRow.reg_request_id = configRow.reg_request_id
/* join hhs_umx_resp_activity sodRow ON sodRow.reg_request_id = approvedRow.reg_request_id */
left join HHS_UMX_REG_REQUESTS hurr on hurr.reg_request_id = hur.reg_request_id
WHERE
and supervisorRow.ACTIVITY_RESULT_CODE = 'ASP'
AND submittedRow.activity_result_code = 'SBT'
/* AND sodRow.activity_result_code = 'ASD'*/
and hur.REG_REQUEST_ID IN ('262097')
The column that is mostly null, which I want to add in, is sodRow ( that's why the code AND sodRow.activity_result_code = 'ASD' is commented ).
Whenever I put back the extra join for sodRow , it just nulls out everything and I get no results at all. But I want it to work like a NVL or COALESCE, where it only displays that column if it exists, and otherwise just shows everything else.
I tried to create a view first in the code, then to do UNION on it. But it seems like view are only for PL/SQL code.
I also tried the outer joins, but this doesn't work.
I think the problem may be in the WHERE condition of my join code. I did like Dmitri suggest belwo :
AND nvl(sodRow.activity_result_code, 'ASD') = 'ASD'
AND nvl(configRow.activity_result_code, 'ACL') = 'ACL'
or also alternatively :
problem is that it won't return any rows. I.E If we're looking for 'ACL' then the previous check of 'ASD' becomes true and will render the next check useless.
I think I'm just having trouble visualizing how the joins work here
, thanks !
May be you can try left outer join
left outer join hhs_umx_resp_activity sodRow ON sodRow.reg_request_id = approvedRow.reg_request_id
and nvl
AND nvl(sodRow.activity_result_code, 'ASD') = 'ASD'
it will return records with null in sodRow.activity_result_code or 'ASD' in it
I’m trying to run this SQL using get external.
It works, but when I try to rename the sub-queries or anything for that matter it remove it.
I tried as, as and the name in '', as then the name in "",
and the same with space. What is the right way to do that?
Relevant SQL:
SELECT list_name, app_name,
(SELECT fname + ' ' + lname
FROM dbo.d_agent_define map
WHERE map.agent_id = tac.agent_id) as agent_login,
input, CONVERT(varchar,DATEADD(ss,TAC_BEG_tstamp,'01/01/1970'))
FROM dbo.maps_report_list list
JOIN dbo.report_tac_agent tac ON (tac.list_id = list.list_id)
WHERE input = 'SYS_ERR'
AND app_name = 'CHARLOTT'
AND convert(VARCHAR,DATEADD(ss,day_tstamp,'01/01/1970'),101) = '09/10/2008'
AND list_name LIKE 'NRBAD%'
ORDER BY agent_login,CONVERT(VARCHAR,DATEADD(ss,TAC_BEG_tstamp,'01/01/1970'))
You could get rid of your dbo.d_agent_define subquery and just add in a join to the agent define table.
Would this code work?
select list_name, app_name,
map.fname + ' ' + map.lname as agent_login,
input,
convert(varchar,dateadd(ss,TAC_BEG_tstamp,'01/01/1970')) as tac_seconds
from dbo.maps_report_list list
join dbo.report_tac_agent tac
on (tac.list_id = list.list_id)
join dbo.d_agent_define map
on (map.agent_id = tac.agent_id)
where input = 'SYS_ERR'
and app_name = 'CHARLOTT'
and convert(varchar,dateadd(ss,day_tstamp,'01/01/1970'),101) = '09/10/2008'
and list_name LIKE 'NRBAD%'
order by agent_login,convert(varchar,dateadd(ss,TAC_BEG_tstamp,'01/01/1970'))
Note that I named your dateadd column because it did not have a name. I also tried to keep your convention of how you do a join. There are a few things that I would do different with this query to make it more readable, but I only focused on getting rid of the subquery problem.
I did not do this, but I would recommend that you qualify all of your columns with the table from which you are getting them.
To remove the sub query in the SELECT statement I suggest the following:
SELECT list_name, app_name, map.fname + ' ' + map.lname as agent_login, input, convert(varchar,dateadd(ss, TAC_BEG_tstamp, '01/01/1970))
FROM dbo.maps_report_list inner join
(dbo.report_tac_agent as tac inner join dbo.d_agent_define as map ON (tac.agent_id=map.agent_id)) ON list.list_id = tac.list_id
WHERE input = 'SYS_ERR' and app_name = 'CHARLOTT' and convert(varchar,dateadd(ss,day_tstamp,'01/01/1970'),101) = '09/10/2008'
and list_name LIKE 'NRBAD%' order by agent_login,convert(varchar,dateadd(ss,TAC_BEG_tstamp,'01/01/1970'))
I used parentheses to create the inner join between dbo.report_tac_agent and dbo.d_agent_define first. This is now a set of join data.
The combination of those tables are then joined to your list table, which I am assuming is the driving table here. If I am understand what you are trying to do with your sub select, this should work for you.
As stated by the other poster you should use table names on your columns (e.g. map.fname), it just makes things easy to understand. I didn't in my example because I am note 100% sure which columns go with which tables. Please let me know if this doesn't do it for you and how the data it returns is wrong. That will make it easier to solve in needed.
