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

I want to figure out what's memory leak point and I have tried the following solutions but none worked:
1.I have tried to dump the memory of the JVM but failed,I can see the following errors :
[root@localhost xxx]# jmap -heap:format=b 3027

2.and the thread stack can not be dumped successfully as well:

I have to added dump thread stack option in JVM arguments, -XX:+HeapDumpOnOutOfMemoryError.
If there are other solutions please let me know, thanks.

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!

I have the following code in my stored procedure:

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.

INSERT INTO table. . . SELECT field1, field2 From. . . .bug

Hi,
I should remember this but . . . bug with t-sql using Insert Into on a temp table. It is unhappy with fields I'm trying to insert.
It's probably the fact that I'm trying to using some default data w/ aliases for a couple of the fields.
Have a look at code please, and tell me how to correct. Thanks!

Temp tables are how a bad programmer fakes a scratch tape so his SQL can look like magnetic tape files. We do not like to materialize data on the disk unless we have to.
And data element do not change names from table to table in a schema! Get rid of the aliases, even tho they are closer to ISO-11179 than the base table crap.
But you are an old FORTRAN programmer! Your "OODETL” is six uppercase letters as required by FORTRAN I; an SQL programmer would have used something like “Order_Details” instead. The mix of camelCase, FORTRAN and several other non-SQL languages is scary.
Why did you use MONEY? It is not portable and the math is wrong. Google it! Why do you think that “<something>_code_id” makes any sense? A data element can be a “<something>_code” or a “<something>_id” but never that hybrid disaster.
I would do this with VIEWs so that I know the data is always current.
CREATE VIEW NC_GL_Items (..)
AS
SELECT DISTINCT OD.l_line, OD.ldr_color, OD.ldr_spec,
AD.addon_mod_gl_acct
FROM Oodetl AS OD,
Addon_Master AS AD
WHERE ..;
The SELECT DISTINCT should not be there. An account should not be NULL, etc. Why do you have more nulls in one table than entire accounting systems? Why do you set integer zero to an amount, which should be a decimal for money?
This is a crazy quilt that is clearly a bitch to maintain or even read. Can you clean it up or are you screwed?

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 to do a SELECT from different tables into an internal table?

How to do a SELECT from different tables into an internal table?
I want to select data from MARA, MARC and ZPERSON and populate my ITAB_FINAL
REPORT zinternal_table.
TABLES:
mara,
marc,
zperson.
TYPES:
BEGIN OF str_table1,
v_name LIKE zperson-zname,
v_matnr LIKE marc-matnr,
v_emarc LIKE marc-emarc,
v_werks_d LIKE marc-werks_d,
v_dstat LIKE marc-dstat,
END OF str_table,
i_table1 TYPE STANDARD TABLE OF str_table1.
DATA:
BEGIN OF str_table2,
v_mandt LIKE mara-mandt,
v_ernam LIKE mara-ernam,
v_laeda LIKE mara-laeda,
END OF str_table2,
itab_final LIKE STANDARD TABLE OF str_table2.

first find the link between mara , marc and zperson , if u have link to 3 tables then u can jus write a join and populate the table u want ( thats final table with all the fields).
u defenitely have alink between mara and marc so join them and retrieve all data into one internal table.
then for all the entries in that internal table retrieve data from zperson into another internal table.
then loop at one internal table
read another internal table where key equals in both the tables.
finally assign fileds if sy-subrc = 0.
gs_finaltable-matnr = gs_table-matnr
etc...
and finally append gs_finaltable to gt_finaltable.
there u go ur final table has all the data u want.
regards

Insert into table a (select * from table b) - need pk?

Hi there.
I'm going to insert into table FINAL (select * from table STAGING) - same structure but in STAGING the ID column has nulls.
Do I need to provide the ID (primary key) for table FINAL or will it get created based on sequence/trigger?
If I were doing this in a loop I'd get the next val from the sequence but on a simple insert, I'm curious.
thanks!

hmm.. what is ?
it didn't like it.

How do i insert into table through forms

Hi
I have developed a custom form based on custom table.
the only way to insert data into database table is through form.
there are two tables: one table is to store all contract details & second table is to maintain history forthis.
one condition(col1,col2,col3,col4) are unique combination,we are not creating any PK or FK at database level.evrythng is captured at form level.
if all 4 columns combination exist thn e should not insert that record.
if 4 columns combination doesnot exist then insert into table.
I have used just pre insert,pre update triggers.
I think its a basic form functionality ,by itself it inserts ,update record.now it is doing the same thng.
But I have to add the above condition ,how can i do that.
Pl provide me some ex code .
Thank you.
Hope any one can help me

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.

How to insert into table when ID auto increment?

I have a table Employee with EmloyeeID, EmployeeName, Email...
When i design table in database, i created a Sequence and then Trigger for EmployeeID to auto increment.
Now in ADF, actually in my web form: I don't want enter values for EmployeeID to insert into table,
but still error : required for EmployeeID...
how can i do it? Thanks

Reg: read excel column and insert into table.

hi Friends,
      i wanted to read the data from Excel and insert into in my oracle tables.
      can you provide the link or example script.
    how to read the column value from excel and insert into table.
please help.

Here are the steps:
1) First create a directory and grant read , write , execute to the user from where you want to access the flat files and load it.
2) Write a generic function to load PIPE delimited flat files:
CREATE OR REPLACE FUNCTION TABLE_LOAD ( p_table in varchar2,
p_dir in varchar2 DEFAULT ‘YOUR_DIRECTORY_NAME’,
P_FILENAME in varchar2,
p_ignore_headerlines IN INTEGER DEFAULT 1,
p_delimiter in varchar2 default ‘|’,
p_optional_enclosed in varchar2 default ‘”‘ )
return number
is
– FUNCTION TABLE_LOAD
– PURPOSE: Load the flat files i.e. only text files to Oracle
– tables.
– This is a generic function which can be used for
– importing any text flat files to oracle database.
– PARAMETERS:
– P_TABLE
– Pass name of the table for which import has to be done.
– P_DIR
– Name of the directory where the file is been placed.
– Note: The grant has to be given for the user to the directory
– before executing the function
– P_FILENAME
– The name of the flat file(a text file)
– P_IGNORE_HEADERLINES
– By default we are passing 1 to skip the first line of the file
– which are headers on the Flat files.
– P_DELIMITER
– Dafault “|” pipe is been passed.
– P_OPTIONAL_ENCLOSED
– Optionally enclosed by ‘ ” ‘ are been ignored.

l_cnt := l_cnt + 1;
end loop;
l_cnames := rtrim(l_cnames,’,');
L_BINDVARS := RTRIM(L_BINDVARS,’,');
L_INPUT := UTL_FILE.FOPEN( P_DIR, P_FILENAME, ‘r’ );

end;
END IF;
if not v_eof then

loop
begin
utl_file.get_line( l_input, l_lastLine );
exception
when NO_DATA_FOUND then
exit;
end;
if length(l_lastLine) > 0 then
for i in 1 .. l_cnt-1
LOOP
dbms_sql.bind_variable( l_theCursor, ‘:b’||i,
ltrim(rtrim(rtrim(

end loop;
begin
l_status := dbms_sql.execute(l_theCursor);
l_rowCount := l_rowCount + 1;
exception
when OTHERS then
L_ERRMSG := SQLERRM;
insert into BADLOG ( TABLE_NAME, ERRM, data, ERROR_DATE )
values ( P_TABLE,l_errmsg, l_lastLine ,systimestamp );
end;
end if;
end loop;
dbms_sql.close_cursor(l_theCursor);
utl_file.fclose( l_input );
commit;
end if;
insert into IMPORT_HIST (FILENAME,TABLE_NAME,NUM_OF_REC,IMPORT_DATE)
values ( P_FILENAME, P_TABLE,l_rowCount,sysdate );
UTL_FILE.FRENAME(
P_DIR,
P_FILENAME,
P_DIR,
REPLACE(P_FILENAME,
‘.txt’,
‘_’ || TO_CHAR(SYSDATE, ‘DD_MON_RRRR_HH24_MI_SS_AM’) || ‘.txt’
commit;
RETURN L_ROWCOUNT;
end TABLE_LOAD;
Note: when you run the function then it will also modify the source flat file with timestamp , so that we can have the track like which file was loaded .
3) Check if the user is having UTL_FILE privileges or not :
SQL> SELECT OWNER,
OBJECT_TYPE
FROM ALL_OBJECTS
WHERE OBJECT_NAME = ‘UTL_FILE’
AND OWNER =<>;
If the user is not having the privileges then grant “UTL_FILE” to user from SYS user:
SQL> GRANT EXECUTE ON UTL_FILE TO <>;
4) In the function I have used two tables like:
import_hist table and badlog table to track the history of the load and another to check the bad log if it occurs while doing the load .
Under the same user create an error log table to log the error out records while doing the import:
SQL> CREATE TABLE badlog
errm VARCHAR2(4000),
data VARCHAR2(4000) ,
error_date TIMESTAMP
Under the same user create Load history table to log the details of the file and tables that are imported with a track of records loaded:
SQL> create table IMPORT_HIST
FILENAME varchar2(200),
TABLE_NAME varchar2(200),
NUM_OF_REC number,
IMPORT_DATE DATE
5) Finally run the PLSQL block and check if it is loading properly or not if not then check the badlog:
Execute the PLSQL block to import the data from the USER:
SQL> declare
P_TABLE varchar2(200):=<>;
P_DIR varchar2(200):=<>;
P_FILENAME VARCHAR2(200):=<>;
v_Return NUMBER;
BEGIN
v_Return := TABLE_LOAD(
P_TABLE => P_TABLE,
P_DIR => P_DIR,
P_FILENAME => P_FILENAME,
P_IGNORE_HEADERLINES => P_IGNORE_HEADERLINES,
P_DELIMITER => P_DELIMITER,
P_OPTIONAL_ENCLOSED => P_OPTIONAL_ENCLOSED
DBMS_OUTPUT.PUT_LINE(‘v_Return = ‘ || v_Return);
end;
6) Once the PLSQL block is been executed then check for any error log table and also the target table if the records are been successfully imported or not.

Insert into table a large amount of records

I was trying to find a fast way to optimize a script that insert a large amount of records into a table. The initial script was like
insert into table_xxxx
select a.camp1, a.camp2, a.camp3 a.camp4, b.camp1, b.camp2, b.camp3
from table_a a, table_b b
where a.camp0 = b.camp0
The commit sentence was at the end of the insert script; so i came up with this solution
Declare
TYPE cur_CURSOR IS REF CURSOR ;
TYPE Tab_Hist IS TABLE OF table_xxxx%ROWTYPE INDEX BY BINARY_INTEGER;
g_tHist Tab_Hist;
CURSOR c_Base IS
select a.camp1, a.camp2, a.camp3 a.camp4, b.camp1, b.camp2, b.camp3
from table_a a, table_b b
where a.camp0 = b.camp0;
BEGIN
OPEN c_base;
LOOP
FETCH c_base BULK COLLECT INTO g_tHist LIMIT 1000;
EXIT WHEN g_tHist.COUNT = 0;
BEGIN
FORALL i IN g_tHist.FIRST .. g_tHist.COUNT SAVE EXCEPTIONS
INSERT INTO prov_cobr_dud VALUES g_tHist(i);
COMMIT;
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
END;
g_tHist.DELETE;
EXIT WHEN c_base%NOTFOUND;
END LOOP;
CLOSE c_base;
commit;
END;
If anyone could tell me another way to do the same thing i'll apreciate it a lot; i'm keen on learn more efficient ways to optimize scripts.
PD: The initial insert was inserting the table with 120,000 records (more or less)

Hello,
Wrong forum. This is the Oracle Forms forum. You should post in the SQL-PL/SQL forum.
