My code is as below"
select * into tbltemp
from table1 where ID='12345'
update tbltemp set ID='54321'where ID='12345'
insert into table1
select * from tbltemp where ID='54321'
drop table tbltemp
When executing insert into query, I got error saying 'Insert Error: Column name or number of supplied values does not match table definition.'
I wonder how I can deal with that?
My table1 has 50 columns with three computed columns.
Thanks for advice!
table1 and tbltemp must match by number of columns. You must explicitly name the columns do not use the * sign in insert into from select, if number of columns do not match.
I just realized that when I have computed columns, the query doesn't work well.
So I delete the computed columns before copy a new one, then do an insert into select *, then add computed columns back, in this way I can save the time for writing 50 fields.
You can't insert a computed column. You need to select especific fields in select and in value() statements. No select *

I have table 1.
I have another empty table 2 with the following columns.
I want to insert into table 2 by selecting from table 1 - so I write the query as:
insert into table2(employee,id,zone,url)
select employee, id, zone, concat('https://',employee,'.com/',id,'?',zone)
from table1
Now my table 2 looks like this,
Now for the authcode column, I do the following and insert it into the table2.
insert into table2(authcode)
SELECT CONVERT(VARCHAR(10),HASHBYTES('MD5', substring(URL,8,100)),2)
from table2.
But the insert happens differently like this AS AN ENTIRE NEW SET OF ROWS.
Can someone help me to insert the last column to the corresponding rows instead of it creating a new one?
What you should be doing is UPDATE the table to fill the column authcode, but you could do it all in 1 step while you are inserting the rows:
insert into table2(employee,id,zone,url, authcode)
select
employee,
id,
zone,
concat('https://',employee,'.com/',id,'?',zone),
CONVERT(VARCHAR(10),HASHBYTES('MD5', substring(concat('https://',employee,'.com/',id,'?',zone),8,100)),2)
from table1
or if you want to update:
update table2
set authcode = CONVERT(VARCHAR(10),HASHBYTES('MD5', substring(URL,8,100)),2)
where authcode is null
The result you are seeing is the intended behavior for an INSERT statement. It will always insert new rows.
If you want to modify existing rows your need to use an UPDATE statement.
You can either modify your INSERT to look like what #forpas has posted to get all this work done in one step. Another option is to modify the second INSERT to be an UPDATE like the following:
update table2
set authcode = CONVERT(VARCHAR(10),HASHBYTES('MD5', substring(URL,8,100)),2)
I have a scenario, where 100's of select statements sql's are in one metadata table or some text file.
Need to insert all sql results into one specific table. (master table has col1, col2,col3 .... 200columns )
problem im facing(ORA-00947) is every select statement has different number of columns.
.. i need to generate INSERT PART.
CASE 1 : INSERT INTO (COL1,COL2,COL3) <<this select part comes from file/variable>>
CASE 2 : INSERT INTO (COL1) <<this select part comes from file/variable>>
CASE 3 : INSERT INTO (COL1) <<this select part comes from file/variable>>
have to figure out how many columns are in select part then generate INSERT part.
.
Thought of create as select but problem is some select statement has max(col) without alias so it will fail.
This is too long for a comment.
If you are storing SQL in a table, then you are constructing your query dynamically. So, update the table and list the columns that you want.
You could then construct the inserts as :
insert into master_table (<column list here>)
<select here>;
Both the select and column list would come from the table.
By far the easiest is to create a view for each SELECT statement. Then you can query the USER_TAB_COLUMNS view on the view name and get the column names.

I have Audit table with more than 50 columns and need to insert desired row (duplicate) by changing just one column value (column CreatedDate, set value to GETDATE()). I know this can be achieved by INSERT INTO SELECT * FROM but as there is more han 50 columns, code would seem messy:
INSERT INTO Audit_Table (Col1, Col2, .....CreatedDate, ......, Col50, ...ColN)
SELECT (Col1, Col2, .....GETDATE(), ......, Col50, ...ColN) FROM Audit_Table
WHERE Audit_Table.Id = Desired_Id
If i shouldn't change CreatedDate column value, it would be very simple:
INSERT INTO Audit_Table SELECT * FROM Audit_Table WHERE Audit_Table.ID = Desired_Id
Is there any other way to duplicate row and change only one/desired column value?
You can insert the record into a temporary table, update the CreatedDate column to GETDATE(), then insert it into the Audit_Table.
No. There is no way to say * except column_foo in SQL.
The workaround would be to generate the
SELECT
col1
, col2
, [...]
, coln
FROM foo;
statement (or parts of it) by querying the database's system catalogue for the column names in their order. There is always a table with all tables and a table with all columns.
Then, make sure you put the necessary commas in the right place (or remove them where you don't need them, or generate the comma in all rows of the report but the first - by using the ROW_NUMBER() OLAP function and evaluating whether it returns 1 or something else). Finally, edit the right date column, by replacing it with CURRENT_DATE or whatever your database uses for the current day.
Good luck -

You can build upon your existing idea. Just duplicate the row (I assume, you have an auto-incrementing primary key column) and then in a separate query update the time i.e.
Do this :
INSERT INTO Audit_Table SELECT * FROM Audit_Table WHERE Audit_Table.ID = Desired_Id
And then :
UPDATE Audit_Table SET CreatedDate = GETDATE() WHERE primaryKeyID = newPrimaryKeyID
Hope this helps!!!
try below as reference
you can use below statement to copy the all rows,
mysql> insert into newstudent select * from students;
you can use below statement to copy the specific row from table,
mysql> insert into newstudent
-> select id, name, age, address
-> from students
-> where
-> id = 1248;
you can use below statement to copy the either of the row from table,
mysql> insert into newstudent
-> select id, name, age, address
-> from students
-> where
-> id = 1248 or id=1249;
use limit clause also along with this
I want to insert data into one table from another table. In some of the columns I don't have data, so I want to set column to null. I don't know how I should do this?
This is the SQL:
INSERT INTO _21Appoint(
PCUCODE,PID,SEQ,
DATE_SERV,APDATE,
APTYPE,APDIAG,D_UPDATE,CID
) SELECT (
NULL,NULL,NULL,
treatment_date,appointment_date,
typeap_id,appointment_id,NULL,patient_id
) FROM cmu_treatment,cmu_appointment
WHERE cmu_treatment.treatment_id LIKE cmu_appointment.treatment_id;
Your insert is essentially correct. Just don't put the column list in parentheses:
INSERT INTO _21Appoint
(PCUCODE,PID,SEQ,DATE_SERV,APDATE,APTYPE,APDIAG,D_UPDATE,CID)
SELECT NULL,NULL,NULL,treatment_date,appointment_date,typeap_id,appointment_id,NULL,patient_id
FROM cmu_treatment,cmu_appointment
WHERE cmu_treatment.treatment_id LIKE cmu_appointment.treatment_id;
In Postgres (unlike other DBMS) putting a column list in parentheses makes the result a single "record", rather then individual columns. And therefore the select only returns a single column, not multiples and thus it doesn't match the column list for the insert
another option is to simply leave out the columns completely:
INSERT INTO _21Appoint
(DATE_SERV,APDATE,APTYPE,APDIAG,CID)
SELECT treatment_date,appointment_date,typeap_id,appointment_id,patient_id
FROM cmu_treatment,cmu_appointment
WHERE cmu_treatment.treatment_id LIKE cmu_appointment.treatment_id;
I am trying to find the syntax for inserting the results from an UNPIVOT statement into an existing table in the database?
simplest answer which works for any SELECT including UNPIVOT would be...
INSERT INTO MyTable
SELECT statement
However, this does require that your destination tables columns match your SELECT statement columns.
Although you can get around this limitation with...
INSERT INTO MyTable (column1, column2....)
SELECT statement
