I have a script which return rows from a table , using which i migrate data/create new tables.
for one of the tables , because it has null values :it returns me some thing like:
insert into table1(column 1, column 2,column 3, column 4) values (abc,,,cdf);
will this insert query work as such or i need to take care of null values.
Edited :my script does this
do a selct query and pick columns from an old separate DB
print an output file where insert query has columns values passed from RESULTSET of above Select statement.
later i use this to directly update new tables in new database.
I am not sure about your requirement ,You can write script like this
insert into table2(column 1, column 2,column 3, column 4)
select column 1,column 2,column 3,column 4 from table1
where isnull(column 1,'')<>'' and isnull(column 2,'')<>'' and isnull(column 3,'')<>'' and isnull(column 4,'')<>''

My select into query would start like this:
insert into camrule (HCHARGECODE, htenant, dtfrom, dtto, IESTIMATETYPE, destimated, imaxpermo)
My hchargecode would be a hardcoded value of 174, my htenant would be based on a select statment (ex. select htenant from tableX), and so on. How can I hardcode the columns and have the other values from the select statments added to my camrule table?
Also, this is for multiple rows, not just a single row to be inserted.
I've tried creating a temp table with the hardcoded values, but am getting an error. I was hoping I could insert the columns from this temp table into my camrule table.
error message
Use the Values keyword to get this done...
insert into camrule (HCHARGECODE, htenant, dtfrom, dtto, IESTIMATETYPE, destimated, imaxpermo)
values(174,(select htenant from tableX), and so on...
This way allows you to select values from different tables, as opposed to just adding hard-coded columns to a Select statement from a single source table.
You can do as simple as:
insert into camrule (
HCHARGECODE, htenant, dtfrom, dtto,
IESTIMATETYPE, destimated, imaxpermo
)
select
174, htenant, dtfrom, dtto,
IESTIMATETYPE, destimated, imaxpermo
from tableX
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 am trying to run this SQL query to copy data from one table to another but it shows zero rows returned:
INSERT INTO ticket_updates
VALUES
(
SELECT *
FROM ticket_updates2
WHERE sequence = '4715'
)
You cannot put a select statement into a values method.
Your syntax should look like this:
INSERT into ticket_updates(all,my,columns)
select all,my,columns from ticket_updates2 where sequence = '4715'
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 have a SQL Server 2008 database. The database has a stored procedure which receives two strings as parameters. One parameter is used to build a temp table which will usually only have 1 or 2 rows but theoretically could have more.
For each row in the temp table, I need to insert a row into a different table that consists of the other parameter and the contents of the temp table. Is there a way to do this without a cursor?
I've tried variations on the following:
Pseudo code:
procedure InsertLinks(#Key varchar(36), #LinkKey varchar(36)
tempLinks Table = getLinks(#LinkKey)
Insert into MyTable (Key, LinksTo) Values (#Key, Select LinksTo From tempLinks)
The VALUES clause is messed up - you have a single value comma a table. That's not valid.
The following should work just fine:
INSERT INTO MyTable (Key, LinksTo)
SELECT #Key, LinksTo
FROM tempLinks
