SQL & PL/SQL :: Procedure To Update Or Insert Data In Multiple Tables
Apr 9, 2011
I'm writing a Procedure which Updates or Inserts data in Multiple tables. Selected fields of 10 tables need to be updated or Inserted. For this I created a table which comprises of fields related to all 10 tables. Then I write Procedure. Under this I create a Cursor which uploads the data from the newly created table which contains different fields of 10 tables. Then I write Update and Insert statements one by one for all 10 tables.
Sample Procedure below.
-------------------------------------------
Create or replace procedure p_proc as
spidm spriden.spriden_pidm%type;
cursor mycur is select * from mytable;
begin
for rec in mycur
[code]......
----------
Note: I created table on my server because data is coming from different server. They will upload the data in the table from there I pick and update the tables. Is updating or Inserting data in different tables one by one is correct?
I am trying to insert records in multiple tables. I know how to view data using joinig, but unable to understand how to insert records in multiple tables using Joining. I searched it on net, but didn't find much. I have also tried to write a code, but it is not working, I have seen some examples on different websites where people are using SELECT in INSERT statement for joining. What is the correct Syntax to INSERT record in Multiple tables.
Insert into library_users, library_users_info (library_users.username, library_users.password, library_users_info.address, library_users_info.phone_no) VALUES (...)
We get data from our customers which we load into temporary tables.The goal is to consolidate this data into one single table.
Following are the rules:
1) final table should have all the columns from all the tables. If there are common column(s) then add only one column with that name.
2) the join would be based on all the common columns
3) if there is a common row, we merge the row into one (example, the row with DOMAIN = ACME.COM)
4) There could be 'N' number of tables
Following is the most realistic data.
1) T1/T2/T3 has the sample data which cover most of our test cases
2) We are expected to transform the data from T1/T2/T3 as depicted in table T4.
3) we might have more than 3 tables in our production environment, so the query should work for N tables.
4) I have given the explanation of how each row should be derived to be inserted in T4
5) the only information we have to work with is the TABLE_NAME(s) and its metadata from USER_TAB_COLUMNS
DROP TABLE T1; DROP TABLE T2; DROP TABLE T3; DROP TABLE T4;
[code].....
Explanation for each row:
row1) This row comes from T1 and T2 (not T3 because HOSTNAME would not match) row2) This row comes from T1 and T3 (not T2 because HOSTNAME would not match) row3) This row comes from T1 and T3 row4) This row comes from T2 and T3 row5) This row comes from T3
I am issuing an update statement in which I am using multiple tables it is giving me an error " set keyword missing"
update E_CONT_DETAIL_NUMB_VALUE ecdnv, y_obj_category yoc, t_contact tc set ecdnv.ContTPRecCount = 1000 where tc.default_category_id = (select primary_key from y_ojb_category where tree_position = 'CONT') and ecdnv.detail_field_id=tc.default_category_id;
update E_CONT_DETAIL_NUMB_VALUE ecdnv, y_obj_category yoc, t_contact tc * ERROR at line 1: ORA-00971: missing SET keyword
I have to write a "after update trigger". Here, i have to update the stock table by other inventory tables (by complex query). I have written trigger below. how to make it correct?
create or replace trigger trg_stk_upd_pur after update on O_STOCK_EFFECTS REFERENCING NEW AS new OLD AS old FOR EACH ROW
I am trying to update multiple columns from one table based on the results of another table So I have 3 tables as follows
HISTORYSUMM_SNAPADM_CHOICE My SQL code is loosely SELECT SUM(H.HIS1), SS.SNAP1, AC.ADM1FROMHISTORY H, SUMM_SNAP SS,ADM_CHOICE ACWHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2GROUP BY SS.SNAP1, AC.ADM1
This works, and I am able to SUM the column as I need with the right numbers. I altered the SUMM_SNAP table and now I want this summarized column to be in the table I tried using UPDATE, but there is no FROM clause to let me do the table join/group by
UPDATE SUMM_SNAPSET SUMM_SNAP.SNAP3=SUM(H.HIS1)FROMHISTORY H, SUMM_SNAP SS,ADM_CHOICE AC WHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2 GROUP BY SS.SNAP1, AC.ADM1
The above is obviously wrong - but just trying to show whatI was thinking What would be the best method to get the numbers from the SUM into a table?
how can i make this script into a function or procedure which instead of user change the crime_id :=4 or 5 directly it actually can grab the id from a update statment like
UPDATE CRIME_STATUS SET CRIME_STATUS = 'open' WHERE CRIME_ID = 9; pick 9 and insert into the above statment so it runs as normal
i have two tables test1 and test2. i want to update the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE v_mydept1 TEST1.DEPT_CD%TYPE; v_mydept2 TEST2.DEPT_CD%TYPE; CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR; [code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF" I am not sure what is the exact problem when we want to update multiple columns of different tables.
i am trying to update multiple records using store procedure but failed to achieve
for example my source is
emp_name sal abhi 2000 arti 1500 priya 1700
i want to increase salary of emp whose salary is less than 2000 it means rest two salary should get update..using stored procedure only
i have tried following code
create or replace procedure upt_sal(p_sal out emp.sal%type, p_cursor out sys_refcursor) is begin open p_cursor for select sal into p_sal from emp; if sal<2000 then update emp set sal= sal+200; end i;f end;
and i have called the procedure using following codes
set serveroutput on declare p_sal emp.sal%type; v_cursor sys_refcursor; begin upt_sal(p_sal,v_cursor); fetch v_cursor into p_sal; dbms_output.put_line(p_sal); end;
the program is executing but i should get o/p like this after updating
I created a data warehouse in oracle 10g n with three Dimension and one cube after that it crates 4 tables . How to use an insert sql statement to insert data in those tables n how to access them.
I have a form which has three detail portions. I want that when I press SAVE, it should insert data in two tables & then run the specific code & then insert data in other two tables.
I am using Developer 6i. Couldn't find out the proper trigger or related thing.
check my query and correct it basically I want to insert/update data from one user to other therefore I write this coding at my form button, when user press button first time its insert data successfully but if user press button again then it should update because data have been inserted in first step.
Actually it is detail table so it can have more then one record against any master. My query fails in updation, it inserts a new record instead of update.

A block shouldn't have rows from multiple tables... Is that true? I read in one of the OTN thread (i don't exactly remember the thread name) that a block can have data from multiple tables. If it doesn't have, what's the table directory in block signifies?
We have to update a single column data in about 10 tables which has child/parent table relations, pk/fk constraints.. The column that we are updating is a part of primary key in half of the tables and part of foreign key in the other half tables.. I'm thinking of disabling all the foreign key constraints in the tables then update the column data then enable the foreign key constraints in these tables.
i've a problem in using store procedure. My code is to get postcode id when i pass a postcode. First it will check the postcode that i pass if already exist it will get postcode id but if not it will insert new postcode and get a new postcode id created then pass into ASP system. When i try run this stock procedure i got error as below :-
SQL> exec INSERT_PCODE_GMDS BEGIN INSERT_PCODE_GMDS; END;
* ERROR at line 1: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'INSERT_PCODE_GMDS' ORA-06550: line 1, column 7: PL/SQL: Statement ignored
( Postcode1 IN varchar2, citiID IN Number, county_ID IN number, city_name IN varchar2, sub_cityID IN number, pcode OUT number ) [code].......
in ASP to pass and get back the values i used code as below. but i think the problems occurs in my stock procedure
