I'm having problem with using the values of an array column in a where clause. Complete example to reproduce:
create type public.genre_type as enum ('scifi', 'fantasy', 'crime', 'horror', 'classics');
create table public.reader_profile(
id integer,
fave_genres genre_type ARRAY
);
create table public.books(
id serial not null,
title text,
genre_type public.genre_type
);
insert into public.reader_profile(id, fave_genres) values (1, array['crime', 'horror']::public.genre_type[]);
insert into public.reader_profile(id, fave_genres) values (2, array['fantasy', 'scifi']::public.genre_type[]);
insert into public.reader_profile(id, fave_genres) values (3, array['scifi', 'classics']::public.genre_type[]);
insert into public.books(title, genre_type) values ('gone with the wind', 'classics');
insert into public.books(title, genre_type) values ('Foundation', 'scifi');
insert into public.books(title, genre_type) values ('Dune', 'scifi');
-- THE FOLLOWING FAILS!!!
select * from public.books
where genre_type in (
select fave_genres from public.reader_profile where id = 2
);
I've tried ...where genre_type = ANY() per other stackoverflow answers as well as ...where genre_type <# () and I can't get anything to work! It seems the inner query (which works) is being return as an array type and not a list of values or something. Any help appreciated!!
I agree with #Hogan that this seems doable with a JOIN but the syntax you are looking for is the following:
SELECT *
FROM books
WHERE genre_type = ANY(ARRAY(SELECT fave_genres FROM reader_profile WHERE id = 2))
;
Demo
Can I suggest using a join instead?
select *
from public.books b
join public.reader_profile fg on b.genre_type = ANY(rp.fave_genres) and fg.id = 2
code :It is merge query which is running on Postgres 9.6.2 and giving syntax error.
<<!--It is giving syntax error--->
MERGE INTO timesheets.timesheet_report AS tgt USING timesheets.tmp_timesheet_report AS src ON src.FMNo = tgt.FMNo
AND src.ts_start_dt = tgt.ts_start_dt
AND src.charge_code = tgt.charge_code WHEN NOT MATCHED
INSERT (tgt.FIRST_NAME,
tgt.LAST_NAME)
VALUES(src.FIRST_NAME,
src.LAST_NAME) WHEN MATCHED
UPDATE
SET tgt.FIRST_NAME = src.FIRST_NAME,
tgt.LAST_NAME = src.LAST_NAME;
It is ON CONFLICT
INSERT INTO table_name [your usual insert syntax here]
ON CONFLICT [some conflict definition]
DO UPDATE SET column1 = EXCLUDED.value1
So I guess your query would look like this:
INSERT INTO timesheets.timesheet_report (FMNo, ts_start_dt, charge_code, FIRST_NAME, LAST_NAME)
SELECT src.FMNo, src.ts_start_dt, src.charge_code, src.FIRST_NAME, src.LAST_NAME FROM timesheets.tmp_timesheet_report AS src
ON CONFLICT (FMNo, ts_start_dt, charge_code)
DO UPDATE
SET FIRST_NAME = EXCLUDED.FIRST_NAME,
LAST_NAME = EXCLUDED.LAST_NAME;
If you don't have primary key or unique index, then you need to create unique index on timesheets.timesheet_report using btree (FMNo, ts_start_dt, charge_code);
My rule to update a view "fva_gpi_sbcpcba_voapcba" isn't properly updating the "product_serial_number" column in both "general_product_info" and "fva_3800" tables.
It only updates the "product_serial_number" in the first table written in the update rule and not both. That is, in this case it will update the fva_3800 table's product_serial_number, but not the general_product_info table's. If I put the UPDATE on general_product_info table first, vice versa.

edit:
fva_3800_product_serial_number_fkey FOREIGN KEY (product_serial_number) REFERENCES product_serial_numbers(product_serial_number) ON UPDATE CASCADE ON DELETE SET NULL
All of the constraints for fkeys are like this. They all have CASCADE and SET NULL.
Here is the definition of fva_3800 table:
CREATE TABLE FVA_3800 (

VOA_PCBA_serial_number varchar(32) REFERENCES VOA_PCBA(VOA_PCBA_serial_number) ON UPDATE CASCADE ON DELETE SET NULL
);
Instead of using Rules, I used Functions and Triggers.
Rules just don't work properly in this situation for UPDATEs nor DELETEs

I have a issue where I want to update a column in a table and with a trigger to update same column but in another table. It says I cannot insert NULL but I can't seem to understand from where it gets that NULL value. This is the trigger:
CREATE TRIGGER Custom_WF_Update_WF_DefinitionSteps_DefinitionId ON WF.Definition
AFTER UPDATE AS BEGIN
IF UPDATE(DefinitionId)
IF TRIGGER_NESTLEVEL() < 2
BEGIN
ALTER TABLE WF.DefinitionSteps NOCHECK CONSTRAINT ALL
UPDATE WF.DefinitionSteps
SET DefinitionId =
(SELECT i.DefinitionId
FROM inserted i,
deleted d
WHERE WF.DefinitionSteps.DefinitionId = d.DefinitionId
AND i.oldPkCol = d.DefinitionId)
WHERE WF.DefinitionSteps.DefinitionId IN
(SELECT DefinitionId FROM deleted)
ALTER TABLE WF.DefinitionSteps CHECK CONSTRAINT ALL
END
END
This update statement works just fine:
UPDATE [CCHMergeIntermediate].[WF].[Definition]
SET DefinitionId = source.DefinitionId + 445
FROM [CCHMergeIntermediate].[WF].[Definition] source
But this one fails:
UPDATE [CCHMergeIntermediate].[WF].[Definition]
SET DefinitionId = target.DefinitionId
FROM [CCHMergeIntermediate].[WF].[Definition] source
INNER JOIN [centralq3].[WF].[Definition] target
ON (((source.Name = target.Name) OR (source.Name IS NULL AND target.Name IS NULL)))
I get the following error:
Msg 515, Level 16, State 2, Procedure Custom_WF_Update_WF_DefinitionSteps_DefinitionId, Line 7
Cannot insert the value NULL into column 'DefinitionId', table 'CCHMergeIntermediate.WF.DefinitionSteps'; column does not allow nulls. UPDATE fails.
If I do a select instead of the update statement, like this:
SELECT source.DefinitionId, target.DefinitionId
FROM [CCHMergeIntermediate].[WF].[Definition] source
INNER JOIN [centralq3].[WF].[Definition] target
ON (((source.Name = target.Name) OR (source.Name IS NULL AND target.Name IS NULL)))
I get this result:

What am I doing wrong? What I don't see? What am I missing..?
The problem was in the trigger at the condition. I modified the second where from i.oldPkCol = d.DefinitionId to i.oldPkCol = **d.oldPkCol** and it worked.
UPDATE WF.DefinitionSteps
SET DefinitionId =
(SELECT i.DefinitionId
FROM inserted i,
deleted d
WHERE WF.DefinitionSteps.DefinitionId = d.DefinitionId
AND i.oldPkCol = **d.oldPkCol**)
WHERE WF.DefinitionSteps.DefinitionId IN
(SELECT DefinitionId FROM deleted)
There are two inserts in my trigger which is fired by an update. My Vendor_Hist table has a field called thID which is the primary key in Task_History table. thID gets its' value from mySeq.nextval.
INSERT INTO TASK_HISTORY
( thID, phId, LABOR, VERSION )
( select mySeq.NEXTVAL, mySeq2.CurrVal, LABOR, tmpVersion
from tasks t
where t.project_id = :new.project_ID );
select mySeq.currval into tmpTHID from dual; -- problem here!
INSERT INTO VENDOR_HIST
( vhID, thID, Amount, Position, version )
( select mySeq3.NEXTVAL, tmpTHID,
Amount, Position, tmpVersion
from vendors v2, tasks t2
where v2.myID = t2.myID
and t2.project_id = :new.project_ID );
Now, my problem is the tmpTHID always the latest value of mySeq.nextVal. So, if thID in task_history is 1,2,3, I get three inserts into vendor_hist table with 3,3,3. It has to be 1,2,3. I also tried
INSERT INTO TASK_HISTORY
( thID, phId, LABOR, VERSION )
( select mySeq.NEXTVAL, mySe2.CurrVal, LABOR, tmpVersion
from tasks t
where t.project_id = :new.project_ID ) returning thID into :tmpTHID;
but then I get a "warning compiled with errors" message when I execute the trigger. How do I make sure that the thID in first insert is also the same in my second insert?
Hope it makes sense.
for i in (select * from tasks t
where t.project_id = :new.project_id)
loop
insert into task_history
( thID, phId, LABOR, VERSION )
values
(mySeq.NEXTVAL, mySeq2.CurrVal, i.LABOR, i.tmpVersion);
for each j in (select * from vendors v
where i.myId = v.myId)
loop
insert into vendor_history
( vhID, thID, Amount, Position, version )
values
(mySeq3.NEXTVAL, mySeq.CURRVAL, j.Amount, j.Position, j.tmpVersion)
end loop;
end loop;
I'm assuming the columns inserted in the second insert are from the VENDORS table; if not, the referencing cursor (i or j) should be used as appropriate.
Instead of the currVal, it works with the following subselect.
( select min(thID) from task_history t3
where t3.project_id = t2.project_id
and t3.myID = t2.myID
and t3.version = tmpVersion ),
