i have multiple inserts to make in a table that is in an Oracle database...i already try several ways to do it but it always giving erros... how to make multiple inserts at same time.
View 2 Replies View RelatedI have a Bash script that counts the rows of a csv file, extracts the fields and makes inserts in a sql file. Then it logs into SqlPlus and calls the insert file. The sql file looks like this:
WHENEVER SQLERROR EXIT
INSERT INTO SCHEMA.TABLE1 (FIELD1, FIELD2, FIELD3)
VALUES (VALUE1, VALUE2, VALUE3);
INSERT INTO SCHEMA.TABLE (FIELD1, FIELD2, FIELD3)
VALUES (VALUE1, VALUE2, VALUE3);
INSERT INTO SCHEMA.TABLE (FIELD1, FIELD2, FIELD3)
VALUES (VALUE1, VALUE2, VALUE3);
[code]....
I rely on "WHENEVER SQLERROR EXIT" for things to go the right path. However sometimes because of the contents of the CVS files (which I can't control) some rows don't get inserted but SqlPlus doesn't see that as an error, doesn't exit and I end up with the wrong number of rows being informed in the second insert.Is there some kind of "if-then-else" construct in Sql? After all the inserts are made, do a "select count (*)" and compare that number to the one informed by the script. If they match, make the final insert and commit; else exit.
create a procedure so that I could get minus query of 2 table as a result.
I have two table 1- src_table_list ,2- tgt_table_list both tables have 2 columns : serial_no,table_name and 100 records each. and details mentioned in column "table_name" are actually tables name which present in my testing database.
so I need one procedure which will pick one table_name from src_table_list and one table_name from tgt_table_name each time recursively and provide minus query as a result. as below.
select c1,c2,c3,c4 from table1 --(fetched from src_table_list)
minus
select b1,b2,b3,b4 from table2 --(fetched from tgt_table_list)
create the procedure..as I have to prepare minus query for more than 200 tables and then I need to test them for integration testing..
select
a.empno,a.ename,a.job,

a.empno,a.ename,a.job,

I have a big table in which we load about 37M recrods. We have informatica ETL which Loads the data in bulk Mode and creats index after completion. The data load takes about 1Hr and Index Creation takes about 1/2 hr. In total it takes about 90 to 95 Mnts.
Now I thought if Partition and Load paralley, It will improve perfromance. We did 4 partition and and each Partition about 9M records. The data load in Bulk mode is completing in 25 Mnts. Again When I am creating index over it, It is taking about 40 Mnts. and in Total Load time is 65 Mnts.
Is there way I can better performance to complete the load in 1/2 hr ?

The below sql is executed by reading the flat file row by row which is having more than 2 million rows.
SELECT CUST_SEQ_R, BANK_BRANCH_C INTO v_CustNo, v_BrnachCode
FROM TABLE1
WHERE ACCOUNT_NO = v_Acc_No
AND VIST_NO = v_VistnO
AND CUST_JOIN_DATE = to_Date(v_Cust_Date,'yyyymmdd');
The procedure opens the file, reads one record, parses it, then it executes few select statements then it loops back to the top where it reads one more record and runs through each activity again. How to read batch of records rather than one record at a time. Is something like creating staging table or by using bulk collect.
v_Acc_No,v_VistnO,v_Cust_Date are variables that read from below file.

It seems certain queries search by the number of days to ship(number of days between the order and shipping dates). What kind of index would improve the performance of these queries?
View 2 Replies View RelatedWhy do stored procedures and functions improve performance?
A. They reduce network round trips.
B. They reduce the number of calls to the database and decrease network traffic by bundling commands.
C. They reduce the number of calls to the database and decrease network traffic by using the local PL/SQL engine.
D. They allow the application to perform high-speed processing locally.
E. They postpone PL/SQL parsing until run time.
I think the answer should be A and B but i came across answers as B and E Can u explain me what is the difference between option A and B and does it postpone parsing till run time?

Without using plsql looping constructs, how to achieve this in a simple sql statement?
I am using an external table with numbers and joining the external table to fetch data and Insert into another table.I am altering the table within procedure to pass csv file name as parameter as It'll change each time. It's working fine but in case if my grouping id is having two gids, then Header from csv file is also inserted as row in to coupon_personlization_members.
I gave skip 1 in external table but for second GID, header is inserted as row.I don't want header to be inserted as row but header will be there on csv file.
Here is my procedure :
CREATE OR REPLACE
PROCEDURE proc_coupon_load(
p_grouping_id NUMBER,
p_file_name VARCHAR2)

In search queries generally we select 10-25 columns (more can't be displayed on the screen) from 5-10 tables
Say in case of insurance related application, the search might be on policy number, policy holder's first name, policy holder's last name, region, policy type etc.
And not to many columns we are displaying on the screen, say, 4 tables have collectively 4 * 20 = 80 columns, then we are displaying say 12-15 columns with 2-3 columns have aggregates on it.
since the search criteria (e.g. first name, last name, policy number etc.) is not known till last moment it will be a generic dynamic query
Is it possible that instead we create a Materialized view with query with only joining conditions but no filter conditions and selecting only columns to be displayed on the screen and then we will refresh the materialized view (to take care of recent business transactions) and fire refined query with filter criteria on this materialized view
Select col1,col2,col3,col4,col5
From tab1,tab2,tab3,tab4
Where tab1.col1=tab2.col1
And tab2.col2=tab3.col2
And tab2.col2=tab4.col2;
Will it improve performance of the search functionality

View 3 Replies View RelatedOur company database is Oracle based and we use SQL Developer to pull out needed data.Using a snippet borrowed from a co-worker, I have put together a query that, among other things, pulls a list value out of an xml clob field and displays it in the query results. My query as it stands right now is below, followed by an example snippet of the xml clob that I am pulling from. The reason for the "query within a query" is because the base query could return multiple entries and I only want the one with the most recent date.
select * from
(Select Wtr_Service_Tag, Wtr_Tran_Origin, Wtr_Send_Date, Wtr_Receive_Date,
to_char(substr(wtr_req_xml,instr(substr(wtr_req_xml,1,8000),'SID')+8,12)) Asset_Tag

This query is only able to pull the first value in the list.How can I edit this query to pull all of the list items when there are more than 1 (preferably concatenated into one column in the query results)? I have another field, in a separate table, that I can pull from to get the number of list items.
This one may be more complex. As currently written, the query pulls a fixed number of characters from the xml clob and either returns not enough data, or too much because the values I need to pull could be of varying lengths. I have no way to query what those lengths might be.

BackgroundCreated a Tabular Form based on a view. Removed all the default multi-row updates and deletions, buttons and processes.I am using a tabular form because of the fact that I can gain access to a row selector.The row data itself is all read only so in effect this is a report with a row selector.This is because I can't find a way to select a row an interactive report, well I can and did but this was a work around. ProblemI have created a button to process the selector to run the below code:
begin
kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'Selected Check Boxes:'||wwv_flow.g_f01(1)) ;
kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'Selected Check Boxes:'||wwv_flow.g_f02(1)) ;
for i in 1..wwv_flow.g_f01.count
loop
kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'i:'||i) ;
kdm_adm_utils.log ('Page', 'XKDM: WF: Current Development', 'WF ID:'|| wwv_flow.g_f02 (wwv_flow.g_f01.count)) ;
end loop;
end;
I just wanted to see what would be output. For one row this works fantastically and I can find the ID based on the rowWhen I select more than one row the loop run's through for the number of rows but then also runs for the number of rows selected.So if I selected threee rows this above procedure would run three times, each times looping three times.I have set the execution scope to: For Created and Modified Rows in the button condition that appears.RequiredI only want to loop through the selected rows once per button clickORKnow which row I am currently looping through.
