So .. I want to have a query that creates multiple rows with one query. Say I want something like this
Row 1: col1 = 'val1', col2 = 'val2', col3 = 'val3'
Row 2: col1 = 'val1', col2 = 'val2', col3 = 'val4'
Row 2: col1 = 'val1', col2 = 'val2', col3 = 'val5'
where
val3,val4,val5
are returned by a sub-query. I was thinking something like
insert into table_name (col1, col2, col3) values ('val1', val2, (select column_name from table_two where condition));
Any ideas how I can do this with one query?
Yes, it's possible: if your val1 and val2 are constant, then:
insert into table_name (col1, col2, col3) select 'val1', 'val2', column_name from table_two where condition;
Try this:
INSERT INTO table_name
(col1, col2, col3)
SELECT
'val1', 'val2', column_name
FROM table_two
WHERE condition;
You are close. However, instead of using the keyword values, select constants. Something like this.
insert into table2
(field1, field2, field3)
select 'fred', 'barney', SomeField
from table1
where whatever.
How about something like
insert into table_name (col1, col2, col3)
SELECT 'val1','val2',column_name
from table_two
where condition
Have a look at SQL INSERT INTO SELECT Statement
use INSERT FROM - have a look at this link here

I am trying to perform an insert using the following command:
insert into table2(COL1, COL2, COL3, COL4) values((select COL1 FROM table1 WHERE COL1 = 121212),120,10,"Y");
But I get the following error:
ERROR at line 1: ORA-00984: column not allowed here
Any help?
INSERT INTO table2( col1, col2, col3, col4 )
SELECT col1, 120, 10, 'Y'
FROM table1
WHERE col1 = 121212
should work.
Is it possible to display which rows I did inserted via this query:
INSERT INTO dbo.Table (Col1, Col2, Col2)
(SELECT
Col1,
Col2,
'Something modified',
FROM dbo.Table
WHERE Col10 = 66)
It is important to obtain whole new row with it's PrimaryKey value, etc., not only Col1, Col2, Col3
The OUTPUT clause is your friend now:
INSERT INTO steam.DocumentGeographies (Col1, Col2, Col3)
OUTPUT inserted.*
(SELECT
Col1,
Col2,
'Something modified',
FROM dbo.Table
WHERE Col10 = 66)
You can insert the result of the OUTPUT by specifying the destination table with the INTO clause or by wrapping the query as a subquery:
INTO clause
This is useful, when you want to insert the same data into two tables. You can always list the required fileds in the OUTPUT clause (inserted.Col1, inserted.Col2)
INSERT INTO steam.DocumentGeographies (Col1, Col2, Col3)
OUTPUT inserted.* INTO DestinationTableName(Col1, Col2, Col3)
(SELECT
Col1,
Col2,
'Something modified',
FROM dbo.Table
WHERE Col10 = 66)
SUBQUERY
This is useful, when you want to join the OUTPUT to another tables or you want to make calculations (like summing or counting values) and insert those results into another table.
INSERT INTO DestinationTableName
(Col1, Col2, Col3)
SELECT Col1, Col2, Col3 FROM (
INSERT INTO steam.DocumentGeographies (Col1, Col2, Col3)
OUTPUT inserted.*
(SELECT
Col1,
Col2,
'Something modified',
FROM dbo.Table
WHERE Col10 = 66)
) TMP
I am trying to copy multiple records using one query using insert select from.
Insert into tab_A(colId, col1, col2, col3)
Select colId, col1, col2, col3 form tab_A
Where colId in ( 2,4,6)
Would it be possible to assign different colId for new entries? For example colid 2 should be replaced with 23, 4 with 24 and 6 with 25. How could I achieve it in a single query?
this would work
Insert into tab_A(colId, col1, col2, col3)
Select 23 , col1, col2, col3 form tab_A Where colId = 2 UNION ALL
Select 24 , col1, col2, col3 form tab_A Where colId = 4 UNION ALL
Select 25 , col1, col2, col3 form tab_A Where colId = 6
If you give some more info I could provide somthing more reusable. Should/is colId (be) an identity column?
EDIT
This would work in this very specialised case
Insert into tab_A(colId, col1, col2, col3)
Select ((colId - 4) * (-1)) + colId + 20 , col1, col2, col3
form tab_A Where colId IN (2, 4, 6)
The function newId = ((oldId - 4) * (-1)) + oldId + 20 is obviously specific to the stated problem.
EDIT2
I suspect somthing like this is more generic approach is appropriate.
DECLARE #MaxColID INT
BEGIN TRANSACTION
SELECT #MaxColID = MAX(ColID) FROM tab_A
INSERT tab_A(colId, col1, col2, col3)
SELECT row + #MaxColID, col1, col2, col3
FROM
(
SELECT ROW_NUMBER() OVER (ORDER BY ColID) row, col1, col2, col3
FROM tab_A WHERE colID IN (2, 4, 6)
)
COMMIT
EDIT 3
If you think EDIT 2 is actually what you want then you really want to make ColID an IDENTITY column, then you could do this.
INSERT tab_A (col1, col2, col3)
SELECT col1, col2, col3 FROM tab_A WHERE colId IN (2, 4, 6)
I dont see col4 or col6 in your query, but is this what you want:
Insert into tab_A(colId, col1, col2, col3)
Select colId, col1, 23, col3 form tab_A
Where colId in ( 2,4,6)
have you just tried adding the disired difference to colId -
In your case, since you need to replace 2 by 23, difference is 21.
Insert into tab_A(colId, col1, col2, col3)
Select colId+21, col1, col2, col3
form tab_A Where colId in ( 2,4,6)
Note: I missed the part, that the differnce is not consistent in your case.
The proposed solution will work only if difference is same
There are a few options:
Add the new ID column to the original table and populate it with the new values before you do this insert, selecting the new ID column instead of the old. This would be the tidiest solution I think.
Alternative - Modify the ID value on the insert based on a rule e.g.
INSERT INTO tab_A(colID, col1, col2, col3)
SELECT colId + 20, col1, col2, col3
FROM tab_A
WHERE colID IN(2,4,6)
Last resort - Process the insert sequentially with a cursor, modifying the ID value each time.
You could also write case in the select. when 2 then 23 or whatever value.
I'm doing an
INSERT INTO table1...
SELECT...
FROM table2
However, I need to retrieve the identity from a table3 and do an insert into it just before inserting into table1. These two inserts need to occur together, with table3 insert going first. I've tried something like this:
INSERT INTO table1 (col1, col2, col3)
SELECT (
col1=(insert into table3(col1, col2)values(1,1) select SCOPE_IDENTITY(),
col2, col3)
FROM table2
But that doesn't work. table1.col1 does need the identity value from the new insert into table3. Amount of data to insert probably no more than a few 100 rows. Any suggestions?
It looks like you might be able to use the Output Clause.
BEGIN TRANSACTION
DECLARE #MyResults table(col1 int, col2 int, col3 int);
INSERT INTO table3 (col1, col2)
OUTPUT SCOPE_IDENTITY(), table2.col2, table2.col3 INTO #MyResults
SELECT 1, 1 FROM table2
INSERT INTO table1 (col1, col2, col3)
SELECT col1, col2, col3 FROM #MyResults
COMMIT
How to modify the following stored procedure if we want in the inserted records the Col3 contain a constant string 'Foo'?
INSERT Table2
(Col1,
Col2,
Col3)
SELECT T1Col1,
T1Col2
FROM Table1
INSERT Table2
(Col1,
Col2,
Col3)
SELECT T1Col1,
T1Col2,
'Something'
FROM Table1
INSERT Table2
(Col1,
Col2,
Col3)
SELECT T1Col1,
T1Col2,
'Foo'
FROM Table1
