I want to insert some data into table tableA, but I have to use group by and my_sequence.nextval. It is impossible to use both in the same statment, is exists any workaround ?
For example:
insert into tableA (
taba_id,
taba_sum,
taba_date
) select
tabb_sequence.nextval,
sum(tabb_value),
tabb_date
from
tableB group by (tabb_date);
After execute this statment, I got:
ORA-02287: sequence number not allowed here
According oracle documentation,I should get this error.
How to deal with sequence and group by caluses in one statment?
The problem here is because your sequence is not aggregated, therefore you have this error. Try this way:
insert into tableA (
taba_id,
taba_date,
taba_sum
)
select tabb_sequence.nextval,
tabb_date,
stv
from (select tabb_date,
sum(tabb_value) stv,
from tableB
group by tabb_date) a;

Could please someone explain, how to use a result from a SELECT (1st select result)
Then use that result (1st select result) on a second query VALUES clause
there is an example (on Microsoft SQL Server) :
--1st query, select all DB1.client.name
select Name from DB1.client
--the result of that query is : 1st select result VALUES : ana,boby, ..., micky
--2nd query, compare DB1.client.name (1st select result) with DB2.client.name
--and get back who doesn't exist on second table
select v.Name
from (values
**(There i want use the result of my first query)**
) as v(Name)
where not exists (select *
from DB2.client c
where c.Name = v.Name);
--the result is ana, ..., micky
"..." mean some other results
i want compare first and second database to retrieve values which aren't in both databases
If you can, I recommend sub-query :
select Name
from DB1.client
where Name not in not exists (select name from DB2.client)
If you want reuse a query (not the result), see #Thkas answer.
It isn't possible to reuse the result in SQL Server, because SQL Server release the memory when the result is read. The trick is to insert the query's result in a temporary table, then you read this temporary table as many times as necessary :
--Insert into temporary table
insert into #tmpResult
select Name from DB1.client
--First read
select Name from #tmpResult
--Second read from sub-query
select Name
from #tmpResult
where Name not in not exists (select name from DB2.client)
According to your sample code I understood something like this. You can add two tables and do with WHERE the check you want.
select a.Name,b.Name
from DB1.client,
DB2.client as b
where a.Name != b.Name;
Also if you want to take as a result set from the first query:
Here I created a subquery which takes the results from the first query. You can correct me for columns.
with temp as (
select Name
from DB1.client
)select a.Name,b.Name
from temp as a ,
DB2.client as b
where a.Name != b.Name;
I would like to insert some data into a table. One field I would like to get from another table, so I'm using select statement inside. This is the code:
INSERT INTO t.table1 (
id,
id_t2,
date_of_change
)
VALUES (
t.table1_seq.nextval,
SELECT s.id_id_t2 from t.table2 s where s.something='something',
TO_DATE('02/05/2017 13:43:34','DD/MM/YYYY HH24:MI:SS')
)
Although select statement is always returning only 1 field (1 row), I presume this is why I'm getting the error.
How can I write INSERT statement with SELECT statement for just 1 field? Can it be done? If not, is there any other solution for this problem? Thank you.
You can translate your whole insert statement into the form of
insert into table1 (fields)
select fields from table2
This will allow you to specify in your select some values from the source table and some constant values. Your resulting query would be
INSERT INTO t.table1 (
id,
id_t2,
date_of_change
)
SELECT t.table1_seq.nextval,
s.id_id_t2,
TO_DATE('02/05/2017 13:43:34','DD/MM/YYYY HH24:MI:SS')
FROM t.table2 s
WHERE s.something='something'
I'm trying to do upset query in Postgres 9.5 using "WITH"
with s as (
select id
from products
where product_key = 'test123'
), i as (
insert into products (product_key, count_parts)
select 'test123', 33
where not exists (select 1 from s)
returning id
)
update products
set product_key='test123', count_parts=33
where id = (select id from s)
returning id
Apparently I'm retrieving the id only on the updates and get nothing on insertions even though I know insertions succeeded.
I need to modify this query in a way I'll be able the get the id both on insertions and updates.
Thanks!
It wasn't clear to me why you do at WITH first SELECT, but the reason you get only returning UPDATE id is because you're not selecting INSERT return.
As mentioned (and linked) in comments, Postgres 9.5 supports INSERT ON CONFLICT Clause which is a much cleaner way to use.
And some examples of before and after 9.5:
Before 9.5: common way using WITH
WITH u AS (
UPDATE products
SET product_key='test123', count_parts=33
WHERE product_key = 'test123'
RETURNING id
),i AS (
INSERT
INTO products ( product_key, count_parts )
SELECT 'test123', 33
WHERE NOT EXISTS( SELECT 1 FROM u )
RETURNING id
)
SELECT *
FROM ( SELECT id FROM u
UNION SELECT id FROM i
) r;
After 9.5: using INSERT .. ON CONFLICT
INSERT INTO products ( product_key, count_parts )
VALUES ( 'test123', 33 )
ON CONFLICT ( product_key ) DO
UPDATE
SET product_key='test123', count_parts=33
RETURNING id;
UPDATE:
As hinted in a comment there might be slight cons using INSERT .. ON CONFLICT way.
In case table using auto-increment and this query happens a lot, then WITH might be a better option.

I'm attempting to do an essentially very simple task, which is resulting in:
ORA-00928: missing SELECT keyword
All I'm trying to do is persist the results from periods into table globalTable. Selecting works fine (I'm returned rows) however as soon as I replace it with the Insert I get the above error.
create global temporary table globalTable
(
ids number(11)
);
with periods as
(
select cl.id uniqueId
from inv_mpan_hh_con_lines cl
left join invoice_vat_lines vl on
cl.invoice_id = VL.INVOICE_ID
where rownum < 4
)
--//Issue occurs at insert keyword. If I comment it and uncomment select it works as expected//--
--select uniqueId
insert into globalTable
from periods;
Any pointers are much appreciated.
Try this:
insert into globalTable
with periods as
(
select cl.id uniqueId
from inv_mpan_hh_con_lines cl
left join invoice_vat_lines vl
on cl.invoice_id = VL.INVOICE_ID
where rownum < 4
)
select uniqueId
from periods;
CTE (WITH-clause) is a part of SELECT statement, according to the INSERT syntax you can either specify values or SELECT statement
I am trying to select data from one table
and insert the data into another table
SELECT ticker FROM tickerdb;
Using OracleSql I am trying to
get the ticker symbol "GOOG" from the tickerdb table,
and insert the t.ticker into the stockdb table.
select from tickerdb table --> insert into quotedb table
INSERT INTO quotedb
(t.ticker, q.prevclose, q.opn, q.rnge,
q.volume, q.marketcap, q.dividend, q.scrapedate)
VALUES (?,?,?,?,?,?,?,?,SYSDATE)
tickerdb t inner JOIN quotedb q
ON t.ticker = q.ticker
From the oracle documentation, the below query explains it better
INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;
You can read this link
Your query would be as follows
//just the concept
INSERT INTO quotedb
(COLUMN_NAMES) //seperated by comma
SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker
Note: Make sure the columns in insert and select are in right position as per your requirement
Hope this helps!
You can use
insert into <table_name> select <fieldlist> from <tables>
try this query below:
Insert into tab1 (tab1.column1,tab1.column2)
select tab2.column1, 'hard coded value'
from tab2
where tab2.column='value';
You will get useful information from here.
SELECT ticker
INTO quotedb
FROM tickerdb;
