I have a query like so:
insert into mySchema.myTable (award_id, cust_id) values ('blahblah', 12345)
where not exists (select * from mySchema.myOtherTable where cust_id = 12345);
I am getting error:
ILLEGAL USE OF KEYWORD WHERE. TOKEN FOR <END-OF-STATEMENT> NOT ATOMIC WAS EXPECTED SQL
Code: -199, SQL State: 42601
I have seen a bunch of similar queries accepted as answers, and I don't understand why it's finding issue with this.
This will work:
insert into mySchema.myTable (award_id, cust_id)
select 'blahblah', 12345
from sysibm.sysdummy1
where not exists (select * from mySchema.myOtherTable where cust_id = 12345);
An alternative to sysibm.sysdummy1 would be:
insert into mySchema.myTable (award_id, cust_id)
select 'blahblah', 12345
from ( values (1) )
where not exists (select * from mySchema.myOtherTable where cust_id = 12345);
I am not sure about that but you can do it like below though
INSERT INTO mySchema.myTable (award_id, cust_id)
SELECT 'blahblah', 12345
WHERE NOT EXISTS
(
SELECT 1 FROM mySchema.myOtherTable WHERE cust_id = 12345
)
(OR)
IF NOT EXISTS (SELECT 1 FROM mySchema.myOtherTable WHERE cust_id = 12345)
BEGIN
INSERT INTO mySchema.myTable (award_id, cust_id)
VALUES('blahblah', 12345)
END
insert into mySchema.myTable (award_id, cust_id)
(select 'blahblah', 12345 from sysibm.sysdummy1
where not exists (select * from mySchema.myOtherTable where cust_id = 12345));
This ended up working.

I'm trying to do a query on Postgres but it's not working. I'd like to create an insert query with 2 select:
Example :
INSERT INTO table1 (id_1, id_2)
SELECT id from table_2 where code='01',
SELECT id from table_2 where code='02';
I don't find the good syntax for this.
I believe below query will works for your use case
INSERT INTO stats(totalProduct, totalCustomer, totalOrder)
VALUES(
(SELECT COUNT(*) FROM products),
(SELECT COUNT(*) FROM customers),
(SELECT COUNT(*) FROM orders)
);
you can changes query accordingly
You can add one more SELECT to achieve this
INSERT INTO table_1 (id_1, id_2)
SELECT
(SELECT id FROM table_2 WHERE code = '01') AS Id_1,
(SELECT id FROM table_2 WHERE code = '02') AS Id_2;
Or you may try with CASE expression:
INSERT INTO table1 (id_1, id_2)
SELECT MAX(CASE WHEN code = '01' THEN id ELSE 0 END) AS Id_1,
MAX(CASE WHEN code = '02' THEN id ELSE 0 END) AS Id_2
FROM table_2
Please refer to the working fiddle on db<>fiddle
I have a scenario where almost all of the tables have issues with the PK value as follows. This results is a database error or the violation of the PK insert.
When using the DBCC CheckIdent it displays an inconsistency between the next value and the current one.
Can anyone have a reason for the mismatch happening on several tables?
Since this database is then replicate, I'm afraid this error will propagate across the environment.
I adapted this script to fix it, but really trying to figure out the root of the problem.

maybe someone or something with enough permissions made a mistake by reseeding?

How to get count of rows for each user_id
select distinct on (user_id) *
from some_table
As in such SQL:
select user_id, count(*)
from some_table
group by user_id
Try this:
SELECT DISTINCT ON (a.user_id)
a.*
FROM
(
SELECT user_id
, count(*) OVER(PARTITION BY user_id)
FROM some_table
) a
If you want to be able to use SELECT * in order to get a "sample row", depending on how large your table is you may be able to use a correlated subquery to get the count of rows for that particular user id:
select distinct on (user_id) *
, (select count (1)
from some_table st2
where st2.user_id = some_table.user_id) as user_row_count
from some_table
Here is my query:
SELECT * FROM table1
WHERE col1 IN (SELECT cola, colb, colc, cold FROM table2)
where all cols are of data type integer. When I execute this query I get "sub query has too many columns". What whould be the right way to do this?
SELECT * FROM table1
WHERE col1 = ANY (
(SELECT array_agg(ARRAY[cola, colb, colc, cold])
FROM a
)::integer[]
);
I am trying to get distinct rows from a temporary table and output them to an aspx page. I am trying to use the value of one column and get the last entry made into that column.
I have been trying to use inner join and max(). However i have been unsuccessful.
Here is the code i have been trying to do it with.
Declare #TempTable table (
viewIcon nvarchar(10),
tenderType nvarchar(20),
diaryIcon int,
customerName nvarchar(100),
projectName nvarchar(100),
diaryEntry nvarchar(max),
diaryDate nvarchar(20),
pid nvarchar(20)
)
insert into #TempTable(
viewIcon,
tenderType,
diaryIcon,
customerName,
projectName,
diaryEntry ,
diaryDate ,
pid
)
select p.viewicon,
p.[Tender Type],
1 diaryicon,
c.[Customer Name],
co.[Last Project],
d.Action,
co.[Diary Date],
p.PID
From Projects2 p Inner Join
(select distinct Pno, max(convert(date,[date of next call],103)) maxdate from ProjectDiary group by Pno
) td on p.PID = td.Pno
Inner Join contacts3 co on co.[Customer Number] = p.[Customer Number]
Inner Join Customers3 c on p.[Customer Number] = c.[Customer Number]
Inner Join ProjectDiary d on td.Pno = d.Pno
Where CONVERT(Date, co.[Diary Date], 103) BETWEEN GETDATE()-120 AND GETDATE()-60
DECLARE #contactsTable TABLE
(pid nvarchar(200),
diaryDate date)
insert into #contactsTable (t.pid, t.diarydate)
select distinct pid as pid, MAX(CONVERT(DATE, diaryDate, 103)) as diaryDate from # TempTable t group by pid
DECLARE #tempContacts TABLE
(pid nvarchar(200))
insert into #tempContacts(pid)
select pid from #contactsTable
DECLARE #tempDiaryDate TABLE (diaryDate date)
insert into #tempDiaryDate(diaryDate)
select distinct MAX(CONVERT(DATE, diaryDate, 103)) from #TempTable
select t.* from #TempTable t inner join (select distinct customerName, M AX(CONVERT(DATE, diaryDate, 103)) AS diaryDate from #TempTable group by customerName) tt on t t.customerName=t.customerName
where t.pid not in
(select Pno from ProjectDiary where convert(date,[Date Of Next Call],103) > GETDATE())
and t.viewIcon <> '098'
and t.viewIcon <> '163'
and t.viewIcon <> '119'
and t.pid in (select distinct pid from #tempContacts)
and CONVERT(DATE, t.diaryDate, 103) in (select distinct CONVERT(DATE, diaryDate, 103) f rom #tempDiaryDate)
order by CONVERT(DATE, tt.diaryDate, 103)
I am trying to get all the distinct customerName's using the max date to determine which record it uses.
Use a subquery. Without going through your entire sql statement, the general idea is:
Select [Stuff]
From table t
Where date = (Select Max(Date) from table
where customer = t.customer)
