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;

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 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;
I have two tables, one is a table #1 contains user information, email, password, etc..
the other table #2 contains item information
when I do a insert into table #2, and then use the returning statement, to gather what was inserted (returning auto values as well as other information), I also need to return information from table #1.
(excuse the syntax)
example:
insert into table #1(item,user) values('this item','the user')
returning *, select * from table 2 where table #1.user = table #2.user)
in other words, after the insert I need to return the values inserted, as well as the information about the user who inserted the data.
is this possible to do?
the only thing I came up with is using a whole bunch of subquery statements in the returning clause. there has to be a better way.
I suggest a data-modifying CTE (Postgres 9.1 or later):
WITH ins AS (
INSERT INTO tbl1(item, usr)
VALUES('this item', 'the user')
RETURNING usr
)
SELECT t2.*
FROM ins
JOIN tbl2 t2 USING (usr)
Working with the column name usr instead of user, which is a reserved word.
Use a subquery.
Simple demo: http://sqlfiddle.com/#!15/bcc0d/3
insert into table2( userid, some_column )
values( 2, 'some data' )
returning
userid,
some_column,
( SELECT username FROM table1
WHERE table1.userid = table2.userid
);
I'm trying to write a query that extracts and transforms data from a table and then insert those data into another table. Yes, this is a data warehousing query and I'm doing it in MS Access. So basically I want some query like this:
INSERT INTO Table2(LongIntColumn2, CurrencyColumn2) VALUES
(SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 FROM Table1 GROUP BY LongIntColumn1);
I tried but get a syntax error message.
What would you do if you want to do this?
No "VALUES", no parenthesis:
INSERT INTO Table2(LongIntColumn2, CurrencyColumn2)
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 FROM Table1 GROUP BY LongIntColumn1;
You have two syntax options:
Option 1
CREATE TABLE Table1 (
id int identity(1, 1) not null,
LongIntColumn1 int,
CurrencyColumn money
)
CREATE TABLE Table2 (
id int identity(1, 1) not null,
LongIntColumn2 int,
CurrencyColumn2 money
)
INSERT INTO Table1 VALUES(12, 12.00)
INSERT INTO Table1 VALUES(11, 13.00)
INSERT INTO Table2
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 FROM Table1 GROUP BY LongIntColumn1
Option 2
CREATE TABLE Table1 (
id int identity(1, 1) not null,
LongIntColumn1 int,
CurrencyColumn money
)
INSERT INTO Table1 VALUES(12, 12.00)
INSERT INTO Table1 VALUES(11, 13.00)
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1
INTO Table2
FROM Table1
GROUP BY LongIntColumn1
Bear in mind that Option 2 will create a table with only the columns on the projection (those on the SELECT).
Remove both VALUES and the parenthesis.
INSERT INTO Table2 (LongIntColumn2, CurrencyColumn2)
SELECT LongIntColumn1, Avg(CurrencyColumn) FROM Table1 GROUP BY LongIntColumn1
I believe your problem in this instance is the "values" keyword. You use the "values" keyword when you are inserting only one row of data. For inserting the results of a select, you don't need it.
Also, you really don't need the parentheses around the select statement.
From msdn:
Multiple-record append query:
INSERT INTO target [(field1[, field2[, …]])] [IN externaldatabase]
SELECT [source.]field1[, field2[, …]
FROM tableexpression
Single-record append query:
INSERT INTO target [(field1[, field2[, …]])]
VALUES (value1[, value2[, …])
Remove VALUES from your SQL.
Remove "values" when you're appending a group of rows, and remove the extra parentheses. You can avoid the circular reference by using an alias for avg(CurrencyColumn) (as you did in your example) or by not using an alias at all.
If the column names are the same in both tables, your query would be like this:
INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn) as CurrencyColumn1
FROM Table1
GROUP BY LongIntColumn;
And it would work without an alias:
INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn)
FROM Table1
GROUP BY LongIntColumn;
Well I think the best way would be (will be?) to define 2 recordsets and use them as an intermediate between the 2 tables.
Open both recordsets
Extract the data from the first table (SELECT blablabla)
Update 2nd recordset with data available in the first recordset (either by adding new records or updating existing records
Close both recordsets
This method is particularly interesting if you plan to update tables from different databases (ie each recordset can have its own connection ...)
inserting data form one table to another table in different DATABASE
insert into DocTypeGroup
Select DocGrp_Id,DocGrp_SubId,DocGrp_GroupName,DocGrp_PM,DocGrp_DocType
from Opendatasource( 'SQLOLEDB','Data Source=10.132.20.19;UserID=sa;Password=gchaturthi').dbIPFMCI.dbo.DocTypeGroup
Do you want to insert extraction in an existing table?
If it does not matter then you can try the below query:
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 INTO T1 FROM Table1
GROUP BY LongIntColumn1);
It will create a new table -> T1 with the extracted information
