INSERT INTO with SELECT CASE

Hi all,
I've this problem: insert into Table_A some values from Table_B... with one derivated/calculated filed.
Example
INSERT INTO Table_A (id_part, vendtype, origin, proven, desc)
SELECT id_p, vendt, origin, proven, <calculate/derivated_field_desc>
FROM Table_BThe rules for calculate the field desc inserted on Table_A are 1. IF vendt='V' AND origin='N' AND proven!='04' THEN ---> desc='TRANSFER'
2. IF vendt='M' AND origin='N' AND proven!='04' THEN ---> desc='IMPORTED'
3. IF proven='04' THEN ---> desc='BAD'So what I use in <calculate/derivated_field_desc> on my INSERT INTO statement??
Can I use a SELECT CASE WHEN... or only DECODE is a right solution?
Edited by: trebbia on 15-nov-2010 12.51

Ok,
I prefer use select case when... because trasform my rules in DECODE statement is more difficult
So I write: INSERT INTO Table_A (id_part, vendtype, origin, proven, desc)
SELECT id_p, vendt, origin, proven, SELECT CASE WHEN vendt='V' AND origin='N' AND proven!='04' THEN 'TRANSFER'
                                                WHEN vendt='M' AND origin='N' AND proven!='04' THEN 'IMPORTED'
                                                WHEN proven='04 THEN 'BAD'
                                                END
FROM Table_BObtain this error:
40/56 PL/SQL: ORA-00936: missing expression
33/1 PL/SQL: SQL Statement ignored
PS: I use '<' '>' and not '!=' in my code... here not prompted correctly '<''>'

INSERT INTO with SELECT invalid column name error

I have a problem where I wish to update a table with only records that have changed or insert into a table with only new records. The Source table is queried using OPENQUERY as we have no staging db for this.
I have the following code (adapted from a working example):
INSERT INTO dbo.Contact
SELECT contactID, lastUpdatedDateTime
FROM
MERGE INTO dbo.Contact AS DT
USING (SELECT * FROM OPENQUERY(LINKED_SERVER,'SELECT contactID, lastUpdatedDateTime FROM Contact')) AS DS
ON (DT.ContactID = DS.ContactID)
WHEN NOT MATCHED THEN
INSERT VALUES (DS.contactID, DS.lastUpdatedDateTime)
WHEN MATCHED AND (DT.lastUpdatedDateTime <> DS.lastUpdatedDateTime) THEN
UPDATE SET DT.contactID = DS.contactID, DT.lastUpdatedDateTime = DS.lastUpdatedDateTime
OUTPUT $Action Action_Out
AS MERGE_OUT
WHERE MERGE_OUT.Action_Out = 'UPDATE';
GO
When I run this query I am getting the following errors referring to the columns in the SELECT:
Msg 207, Level 16, State 1, Line 2
Invalid column name 'contactID'.
Msg 207, Level 16, State 1, Line 2
Invalid column name 'lastUpdatedDateTime'.
Am I missing something obvious as I can't quite work out why? The Target and source definitely exist with the specified columns present in both...

Hello,
The issue is because you are not outputting those values from the inner merge statement. All you are currently outputting is the action, so the error is correct as those columns do not exist.
Change your output portion to be:
OUTPUT inserted.contactID, inserted.lastUpdatedDateTime, $Action Action_Out
Then it should work.

Using combination of insert into and select to create a new record in the table

Hello:
I'm trying to write a stored procedure that receives a record locator parameter
and then uses this parameter to locate the record and then copy this record
into the table with a few columns changed.
I'll use a sample to clarify my question a bit further
-- Create New Amendment
function create_amendment(p_mipr_number in mipr.mipr_number%TYPE, p_new_amendment_number in mipr.amendment_number%TYPE)
return integer is
new_mipr_id integer;
begin
THIS is causing me grief See comments after this block of code
insert into mipr
(select mipr_id from mipr where mipr_number=p_mipr_number),
(select fsc from mipr where mipr_number=p_mipr_number),
45,
(select price from mipr where mipr_number=p_mipr_number),
practical,
(select part_number from mipr where mipr_number=p_mipr_number);
THe above will work if I say the following
insert into mipr
(select * from mipr where mipr_number=p_mipr_number);
BUt, Of course this isn't what I want to do... I want to duplicate a record and change about 3 or 4 fields .
How do I use a combination of more than one select and hard coded values to insert a new record into the table.
/** Ignore below this is fine... I just put a snippet of a function in here ** The above insert statement is what I need help with
select (mipr_id) into new_mipr_id from mipr where mipr_number=p_mipr_number + amendment_number=(select max(amendment_number) + 1);
return new_mipr_id;
end;
THANK YOU IN ADVANCE!
KT

function create_amendment(p_mipr_number in mipr.mipr_number%TYPE)
return integer is
new_mipr_id integer;
tmp_number number;
tmp_mipr_id integer;
begin
tmp_number :=(select max(amendment_number) from mipr where mipr_number=p_mipr_number);
Question:
tmp_number :=1; works..
tmp_number doesn't work with the select statement?
Obviously I'm a novice! I can't find anything in my book regarding tmp variables... What should I look under is tmp_number a
variable or what? In my Oracle book, variable means something different.
Thanks!

INSERT INTO TABLE (SELECT -----)

I laready posted But i think people got confused this is the same query in easiest way
Hi Please please here Insdie the curusr FOR Loop i am using INSERT INTO by SELECT (see the below code EACH INSERT WILL FETCH 800-1000 records Minimum !!!)
In that satement here i am using the MINUS also ,,thi is taking minute to insert each record approx
This way I need to insert 5 insert Into sattement for different tables see EXA
Inside the FOR loop------
INSERT INTO PICKSLIP
( SELECT FIELDS
FROM table p, table d
WHERE ---- AND ---
AND ---
AND -----
IN ( SELECT Fields
FROM p, d
WHERE ---- AND ---
AND ----
MINUS
SELECT PICKSLIP_PREFIX, PICKSLIP_NUMBER FROM C
GROUP BY Fields);
This WAY
5 insert it dam slow taking 1 minutes to insert to all 5 tables ...this way i have lot of recordss....

But i think people got confused this is the same query in easiest way I don't think this is more clear with your current thread. Your query is bad, and shouldn't work at all.
It shouldn't work for too many reasons (at least because AND without nothing behind) and use a group by clause where is not required.

i try to perform simple query : insert into tablea select from tableb which has same structure. the source table has only 9 rows, but the process ran very long time, no error message raised,it just run and never end (which make me upset for the whole day).
i have tried another simple query : insert into table1 values (1,2) using the same driver and execute successfully.
is it becoz of function limitation since i used evaluation copy ?

Copy the answer from HXTT's support forum:
No function limitation. I just tested:
create table testa1 select * from test;
insert into testa1 select * from test;
Passed.
I also run your backofficeDbfVerification.java sample. Passed too. I'm using the same code as you. The difference is only my 89964568.AA1 and 123.AA2 is simulative tables files. If possible, please zip your 89964568.AA1 and 123.AA2 and email to [email protected] Thanks.

QUESTION ON INSERT STATEMENT WITH SELECT

Hi
I have a table which contains three fields
Table name : USERS
ID NUMBER(10),
NAME VARCHAR2(50),
EMAIL VARCHAR2(50)
SEQUENCE by name SEQ_ID
I am trying to insert values into USERS from EMPLOYEE by virtue
of insert into USERS (SELECT NAME, MAIL from EMPLOYEE) but i
want to have one id for all the rows fetched from my inner
query.
I would like to know if here is a way, by which i can fetch a
constant in my select statement which is not present in the
table and use it like
insert into USERS ( SELECT constant, NAME, MAIL FROM EMPLOYEE );
where constant is some number unique for a given insertion.
Thanks
Arun

Why not just try it? All you had to do was type
insert into USERS SELECT 1, NAME, MAIL FROM EMPLOYEE ;
and you would have had your answer immediately instead of
waiting for me to tell you.

Insert into with variables

Hi!
I've a procedure with a insert into phrase.
For example:
INSERT INTO type (NAME) values(A_CHA);
type is not a table name it is a variable and name is not a column name it is also a variable.
Can i make a insert into with variables?
How is the right syntax?
Thank's for help!
Nicole

Hi!
I've found a way to do this:
sql_statement:= 'INSERT INTO' || type_table || '('||NAME|| ',CABLE_NUM,FACILITY_NUM) values( '||A_CHA||','||CABLE_N||','||FAC_N||')';
EXECUTE IMMEDIATE sql_statement;
But when i execute my procedure i get the error:
Keyword INTO is missing!
Please help

You'll have to provide more evidence and example output (format it on the forum by putting {noformat}{noformat} before and after it), so we can see exactly what you are doing.
Are you sure that the table you are inserting into has no rows initially or that you are counting the rows correctly?
Show us exactly what you are doing.

Insert into with problems

Hy,
i have a little question. Try this:
create table strangetab (
id varchar2(20),
textfield varchar2(200)
CREATE OR REPLACE PROCEDURE writestrangetab
id VARCHAR2,
textfield varchar2 default null)
IS
pragma autonomous_transaction;
BEGIN
INSERT INTO strangetab
(id, textfield
) VALUES
(id, textfield
COMMIT;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line(sqlerrm);
rollback;
END;
After table and procedure creation, try to run this script (simple insert into in autonompus_transaction):
set serveroutput on
declare
vstr varchar2(10000);
begin
for i in 1..2000
loop
vstr := vstr||'r';
end loop;
dbms_output.put_line('write a');
writestrangetab( 'idx' , 'a');
dbms_output.put_line('write big string');
writestrangetab( 'idx' , vstr);
dbms_output.put_line('write b');
writestrangetab('idx' , 'b');
end;
The script generate this output:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
write a
write big string
ORA-12899: value too large for column "STRANGETAB"."TEXTFIELD" (actual:
2000, maximum: 200)
write b
As i expect, the second write goes wrong but first and third no and it put string a and b into srangetable.
Now try to run this:
set serveroutput on
declare
vstr varchar2(10000);
begin
for i in 1..5000
loop
vstr := vstr||'r';
end loop;
dbms_output.put_line('write a');
writestrangetab( 'idx' , 'a');
dbms_output.put_line('write big string');
writestrangetab( 'idx' , vstr);
dbms_output.put_line('write b');
writestrangetab('idx' , 'b');
end;
The only difference from the previous is the vstr dimension: first 2000 now 5000.
In my db (10.2.0.4 on linux) the output of this, is:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
write a
write big string
ORA-01461: can bind a LONG value only for insert into a LONG column
write b
ORA-01001: invalid cursor
If i query the strangetable i am non able to find string b (Only string a was registered)!
As if that were not enough, If you try to insert others writestrangetab, anything after wath that produce the error will be stored!
It is normal?

Stefano

Tanks for your reply Jhon, but:
1) "The second run you are trying to pass 5000 characters to a varchar, which caused your error when trying to call your procedure"
Why you say "which caused". When i call a procedure can't pass more than 4000 Chars? I know that pl/sql varchar2 is up to 32000 Chars even in procedure calls!
2) "That is why your cursor because invalid"
Witch cursor? The strange thing is that there isn't any cursor in the autonomous procedure! The anly statement is an insert into!
The problem of the second miss in the second run is ok: that wont register the string. The main problem is the miss of the third in the seconf run.
Why it not register the third writestrangetab? In that case i pass only a 'b' char. Writestarngetab Is an autonomous transaction so i expect a miss if it fail, but the next, if ok, will be registerd. why not?

System getting hanged whilst using Insert into table select * from table

I have a peculiar problem.
I am using the below statements:
Query 1:
insert into table ppms.erin_out@ppms_dblink select * from erin_out;
Query 2:
insert into table ppms.erin_out@ppms_dblink values(23,'dffgg',12',dfdfdgg,dfdfdg);
I am in 'interfaces' schema (testing server) and executing above statements. We have testing server and development server, both are identical, i.e one is clone of the other.
ppms_dblink is created in interfaces schema. ppms_dblink points to different database server which has two schemas 'clarity' and 'ppms'. ppms_dblink is create through authentication details of clarity schema.
erin_out table is created on ppms schema on the same dababase server pointed by ppms_dblink.
Question is :
TOAD hangs while running query 1.
Query 2 is working perfectly.
As I have pl/sql script which is using query 1. I want to know why query 1 is creating problem.
If I use query 2 in my pl/sql query then it may create performance issue as i have to use cursor then.
On clarity schema, I have insert, update, select, modify rights on ppms.erin_out.
I have tried same queries from another database server.
That is I tried queries from 'interfaces' schema of development server ( clone of the testing server ). Its working perfectly.

Dhanchik:
The table from which I select rows, to insert into table on dblink, is having only one record. It may contatin maximum 100 rows at a time because I am scheduling the procedure through daemon process. Anyway transaction is not more than 100 records. I am trying with just 1 record for testing.
So 1) Problem is not about the cost, TOAD is getting hanged ( to insert 1 record, cost does not mean much)
2) there is no large amount of data, so no question of deteriorated performance
Aron Tunzi:
I think that should not be problem, because I am able to insert a record through query 2.
Warren Tolentino :
I am testing with 1 record only. Its not performance issue.

How insert into table select from table works in jdbc driver?

Hi, Supposing one table has two LOB fields, one LOB field is BLOB type while the other is CLOB type, I use the following sql statement to copy a row into a new row:
insert into table (id, file_body, file_content) select new_id, file_body, file_content from table where id = '111';
After commit on the connection, I can see the copied record in the table and both LOB fields are not null and this's the expected behavior.
However after some days later, the copy function becomes to be a problem, the BLOB field named file_body can be null when the copy job is done, while other fields copy successfully.
The issue can not be reproduced every time.
I suppose the jdbc driver may try to allocate byte buffer in the heap to perform copy operation for BLOB fields,if there is no enough memory available in the heap the copy operation may fail but the commit on the connection can be successful.b/c I can see a lot of OOM errors in the log files and I believe this can contribute to the issue.
Hope someone can give me a hint or comments.
Thanks,
SuoNayi

Using default values in INSERT INTO..SELECT..

Hi,
I like to do following insert in Oracle 10g
INSERT
INTO tab1
x1,
x2
SELECT
NVL(y1,DEFAULT),
y2
FROM tab2
but oracle throws missing expression error. I don't want to substitute default values as it involves code change for any default value change. I suppose Oracle changes context to tab2 while SELECT, but is there any way to accomplishing the above INSERT?
Edited by: ponn_raj on Jan 14, 2009 4:52 AM

Hi,
Welcome to the forum!
DECLARE
var number;
BEGIN
    INSERT INTO test
        (col1,
         col2)
    VALUES
        (1,
         NVL(var, 0));
    COMMIT;
END;
/Also you can create the table and assign default values to the columns that you want. See [CREATE TABLE|http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7002.htm#i2095331].
From the link above:
DEFAULT
The DEFAULT clause lets you specify a value to be assigned to the column if a subsequent INSERT statement omits a value for the column. The datatype of the expression must match the datatype of the column. The column must also be long enough to hold this expression.
The DEFAULT expression can include any SQL function as long as the function does not return a literal argument, a column reference, or a nested function invocation.

UPDATE/INSERT INTO with Connection with access DB

Hello,
I am trouble getting the update statement working when connecting to my database. The "Select" statement works fine but i am using:
result2= stmt2.executeUpdate("INSERT INTO Table1 VALUEs('1', '1')");
and i get the error incompatiable types...found int but expected java.sql.resultset
I am not sure what i am doing wrong. Can anyone help?

since you're using Access, be sure to close both your Statement and the Connection you used after your INSERT/UPDATE. It's well known that changes won't show up in Access unless you do.
