I am trying to run a simple insert statement in db2 but getting invalid statement:
my sql :
insert into schema1.table1 select * from schema2.table1
Error:
SQLCODE = -20186, ERROR: A CLAUSE SPECIFIED FOR THE DYNAMIC SQL; STATEMENT BEING PROCESSED IS NOT VALID
I had gone through ibm knowledge center and found this page.
I understand db2 allows 3 forms of insert:
There are three forms of this statement:
The INSERT via VALUES form is used to insert a single row into the table or view using the values provided or referenced.
The INSERT via SELECT form is used to insert one or more rows into the table or view using values from other tables, or views, or both.
The INSERT via FOR n ROWS form is used to insert multiple rows into the table or view using values provided or referenced.
My question is why db2 is looking for "for n rows" clause in my query.
Note: this query is being sent through SSGODBC.
Might want to try and explicitly state the columns.
INSERT INTO Schema1.table1 (col1,col2,...) SELECT col1,col2,... FROM Schema2.table2

I have created a SQL view that retrieves the result set I desire but when I try to add a new set of values it fails. When searching around on the net it appears that VIEW has a few limitations and some types of joins may not be allowed, I have tried to create the view a few different ways but with no success yet, would anyone happen to know a way I could rewrite this create view query that would allow me to insert new values into it?
The view:
CREATE VIEW NATIONAL_ITEMS
AS
SELECT item.itemno, item.itemdesc, item.itemprice
FROM item
FULL OUTER JOIN invoiceitem ON item.itemno = invoiceitem.itemno
WHERE item.itemdesc LIKE '%National%'
AND invoiceitem.invoiceno IS NULL
WITH CHECK OPTION;
My insert statement that does not work:
INSERT INTO NATIONAL_ITEMS
VALUES ('123-456', 'National TV', 100);
I get this error:
Error starting at line : 1 in command -
INSERT INTO NATIONAL_ITEMS VALUES ('123-456', 'National TV', 100)
Error at Command Line : 1 Column : 1
Error report -
SQL Error: ORA-01733: virtual column not allowed here
01733. 00000 - "virtual column not allowed here"
Any help would be greatly appreciated, thank you.
You have two options for the view in order to insert in the view.
First, Your View must contain all the keys present in the table on which you are creating the view i.e there must be no DISTINCT OR GROUP BY clause.
If you performing JOIN on the tables same is applicable for all join tables, all keys from the table must be present in the view and there must be no DISTINCT OR GROUP BY clause.
The table which has 1:1 row relationship with the rows in the view called Key preserving table
Second, you can create instead of trigger on the view. The trigger will be fired instead of INSERT, UPDATE, OR DELETE and in the trigger, you can handle the DML statement.
Since your table is not key preserving then you can make use of INSTEAD OF TRIGGER.
CREATE OR REPLACE TRIGGER NATIONAL_ITEMS_TRG
INSTEAD OF INSERT
ON NATIONAL_ITEMS
FOR EACH ROW
BEGIN
INSERT INTO ITEM(itemno, itemdesc, itemprice) VALUES (:NEW.itemno, :NEW.itemdesc, :NEW.itemprice);
END;
How would I insert into multiple tables with one sql script in db2
For example, insert a row into T1 DOCK_DOOR and then insert into T2 DOCK_DOOR_LANE multiple times based on the dock_door_sysid from the first table.
My first approach was the following. I was attempting to use a with with three inserts. on the other hand, doing to inserts on the second table is not and option if this can be automated with one insert.
thanks for any feedback
sql example
WITH ins AS (
INSERT INTO DBF1.DOCK_DOOR (DOCK_DOOR_SYSID,DOOR_NUMBER,DOOR_NAME,DOCK_SYSID,DOOR_SEQ,ENCRYPTION_CODE,RFID_ENBLD_FLAG,LANES_COUNT,CMNT_TEXT,CREATE_TS,CREATE_USERID,UPDATE_TS,UPDATE_USERID,VER_NUMBER,ACTIVE_FLAG,STATUS_SYSID,DOOR_TYPE_SYSID)
VALUES (nextval for DBF1.DOCK_DOOR_SEQ,'026','DOOR025',61,25,NULL,'N','2',NULL,current timestamp,'SQL_INSERT',current timestamp,'SQL_INSERT',0,NULL,1723,1142)
RETURNING door_number,dock_door_sysid),
ins2 AS (
INSERT INTO SIT.DOCK_DOOR_lane (DOCK_DOOR_LANE_SYSID,DOOR_LANE_ID,DOCK_DOOR_SYSID,LANE_ID,CREATE_TS,CREATE_USERID,UPDATE_TS,UPDATE_USERID,VER_NUMBER)
VALUES (nextval for DBF1.DOCK_DOOR_LANE_seq,door_number||''||'A',dock_door_sysid,'A',current timestamp},'SQL_INSERT',current timestamp,'SQL_INSERT',0)
SELECT door_number,dock_door_sysid FROM DBF1.DOCK_DOOR
RETURNING door_number,dock_door_sysid)
INSERT INTO DBF1.DOCK_DOOR_lane (DOCK_DOOR_LANE_SYSID,DOOR_LANE_ID,DOCK_DOOR_SYSID,LANE_ID,CREATE_TS,CREATE_USERID,UPDATE_TS,UPDATE_USERID,VER_NUMBER)
VALUES (nextval for DBF1.DOCK_DOOR_LANE_seq,door_number||''||'B',dock_door_sysid,'B',current timestamp},'SQL_INSERT',current timestamp,'SQL_INSERT',0)
SELECT door_number,dock_door_sysid FROM DBF1.DOCK_DOOR;
Table 1 = dock_door
Table 2 = Dock_door_lane
You could do it with a trigger on the dock_door table.
However, if you're on a recent, version on IBM i. You might be able to make use of data change table reference
Your statement would look something like this
insert into dock_door_lane
select <....>
from final table (insert into dock_door <...>)
I'm not sure it will work, as this article indicates that at least at a couple of years ago DB2 for i didn't support the secondary insert required.
This old SO question also seems to confirm that at least at v7.1, the double insert isn't supported.
If I get a chance, I'll run a test on a 7.2 system Monday.
I have the following query in SQLRPGLE for DB2:
INSERT INTO ITEMS2 (PROGRAM, VLDFILE, VLDFLD,
SELFILE, SELFLD) VALUES(:SCAPP , 'CSTMR', 'CYC',
'BYC', 'BYCC');
I would like this query to be run in 2 libraries as in FIRST/ITEMS2 and SECOND/ITEMS2
where FIRST and SECOND are the library names. Can this be achieved in one query?
For those who have no understanding of iSeries: The above insert statement would be similar to having a insert query for 2 tables.
The INSERT statement does not support inserting into multiple tables.
However you could create a trigger on FIRST/ITEMS2 to automatically insert/update/delete the record into SECOND/ITEMS2.
See the CREATE TRIGGER statement for more information.
If this will be run often, consider making the INSERT into a stored procedure, and then setting the target schema via SET SCHEMA:
set schema=first;
call my_insert_proc(:scapp);
set schema=second;
call my_insert_proc(:scapp);
You could create a QMQuery like this
INSERT INTO &LIB/ITEMS2
(PROGRAM, VLDFILE, VLDFLD, SELFILE, SELFLD)
VALUES (&SCAPP, 'CSTMR', 'CYC', 'BYC', 'BYCC');
Then
STRQMQRY myQmQry SETVAR(('LIB' 'FIRSTLIB')('SCAPP' &VAR))
STRQMQRY myQmQry SETVAR(('LIB' 'SECONDLIB')('SCAPP' &VAR))
From IBM's Syntax diagram of INSERT ( http://pic.dhe.ibm.com/infocenter/iseries/v7r1m0/index.jsp?topic=%2Fdb2%2Frbafzbackup.htm ), I'd say you have to go with two queries.
But after the first time of executing this query, you can try changing the current library ( http://publib.boulder.ibm.com/infocenter/iadthelp/v7r1/topic/com.ibm.etools.iseries.langref2.doc/chglibl.html ).
At work we have a SQL Server database. I don't know the db that well. I have created a new column in the table for some new functionality....straight away I have started seeing errors
My statement was this:
ALTER TABLE users
ADD locked varchar(50) NULL
GO
The error is:
Insert Error: Column name or number of supplied values does not match table definition
I have read that the error message appears when during an INSERT operation either the number of supplied column names or the number of supplied values does not match the table definition.
But I have checked so many times and i have changed the PHP code to include this columns data yet I still receive the error.
I have run the SQL query directly on the db and still get the error.
Funny enough the query which gets the error is an Update.
UPDATE "users"
SET "users"."date_last_login" = GETDATE()
WHERE id = 1
Have you considered it could be a trigger causing it?
This is the error message you would get.
If its an Update action causing it check trigger actions that Updates on that table run.
Do it with:
#sp_helptrigger Users, 'UPDATE';
This will show triggers occuring with ‘update’ actions.
If there is a trigger, grab the triggers name and run the below (but replace TriggerNameHere with real trigger):
#sp_helptext TriggerNameHere;
This will give you any SQL that the trigger runs and could be the INSERT the error message is referring to.
Hope this helps
Aside from TRIGGERS,
the reason for that is because you are using implicit type of INSERT statement. Let's say your previous number of columns on the table is 3. You have this syntax of INSERT statement,
INSERT INTO tableName VALUES ('val1','val2','val3')
which executes normally fine. But then you have altered the table to add another column. All of your INSERT queries are inserting only three values on the table which doesn't matches to the total number of columns.
In order to fix the problem, you have to update all INSERT statements to insert 4 values on the table,
INSERT INTO tableName VALUES ('val1','val2','val3', 'val4')
and it will normally work fine.
I'll advise you to use the EXPLICIT type of INSERT wherein you have to specify the columns you want to insert values with. Eg,
INSERT INTO tableName (col1, col2, col3) VALUES ('val1','val2','val3')
in this ways, even if you have altered your tables by adding additional columns, your INSERT statement won't be affected unless the column doesn't have a default value and which is non-nullable.
I've never created a trigger before and I'm trying to read online but am a little confused.
I want to create a trigger on a table that on insert, it will grab some data from different columns and insert it into a few different other tables.
I'm not sure how to write the T-SQL to get the data from the columns..
insert into [othetTable]
values ([col1 from row that was inserted], [col5 from row that was inserted])
What would the syntax be to get those values?
thanks
Use the inserted virtual table that is available to triggers. Note that there could be multiple rows in this table - your trigger could be processing multiple inserts at once.
Therefore, you need to use something like the following syntax:
insert into othertable
select col1, col5
from inserted
This will insert a row into othertable for each inserted row.
