I need to write a script which copies 4 col data from one table to another table. there are three tables
cwat_curr_mst and cwat_assigned_customer and cwat_assignment_mst.
Cwat curr mst has PK curr_id and cwat_assigned_customer has PK assignment_id.
Also cwat_assigned_customer has customer_id.
In cwat_assignment_mst has Curr_id and Assignment_ID.
cwat_curr_mst and cwat_assigned_customer tables has 4 cols in common
they are
ASRT_SNM_NO, SNM_NO, FLORIDA_NO, CBRN_NO.
So from curr_mst all these 4 cols data needs to come/copy into cwat_assigned_customer.
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 have to procedure that computes number of project, and average working hours of employees where employee id is passed as a parameter to the procedure. If the average working hours is less than 10 then employee's salary remain the same, otherwise check if number of project is less than 4 then 5% of salary, else 10% of salary is added to the salary.
my tables are:
CREATE TABLE employee(
empid number(5),
empname varchar(20),
address varchar(20),
no_of_dependents number(5),
deptno number(5),
CONSTRAINT EMPLOYEE_PKEY PRIMARY KEY(empid),
CONSTRAINT EMPLOYEE_FKEY FOREIGN KEY(deptno) REFERENCES department(deptno));
[code]...
the problem is i have to use only 2 cursors - 1 for select and 1 for update.
I want the query to generate the sequenctial number from 1 for the new financial year in some query.
View 6 Replies View Relatedwe use oracle 11g. 11.2. I have a situation where in a pl-sql package, there is a modification needs to be done . Every User is associated with destination codes. For eg, user1==>0101,0104 There is a destination_number and country field in the table1.Each of the destination number is associated with a country code and this combination is unique. for eg:
dest_code country_code 0101 CHINA 0202 UK 0101 Mexico 0104 Mexico
For example, if user1 logs in to the system, then pl sql logic will look if that dest_code is in a table1,If the dest_code is present in the table1, then that dest_code number wont be added to the dest_code list formed for that user. For example,if user1 got dest_codes 0101,0104 associated with him.IF 0101 is in exception table then 0101 and 0104wont be used to form dest_code list. If NOT, a dest_code list will formed like 0101||0104. I am able to form the logic like I have a cursor that loops for each dest_code.For each dest_code , it will get that dest_code into v_dest_code_no number type variable. open cursor fetch dest_code no into v_dest_code v_dummy number:=0;v_dest_code_list number:=0; LOOP v_dest_code_list:=v_dest_code ||v_dest_code ; v_dest_code :=0; END LOOP: How to make sure that for each dest_code set, if one of them is in table1, then the next number also will not be added to the list.
I am using regexp_substr to break the pipe delimited string. Want to use the output as the NUMBER input to a cursor.Its not working and not getting any error also.
Here is an example.
initial input : '5545|4124|12456'

View 1 Replies View RelatedI've created a stored procedure which creates itself a view (a MV to be honest); the instructions to create this m.view are dinamically built insinde my procedure, so each time i run it, based on the different input parameters, i've got a different result (my output m.view can have three colums the first time, or ten the next time) how can I read my output view to put the data into file? I've tried with "select * bulk collect into my_array from my_ output_ view"...after declaring "my_array" as a varying array with the max number of colums I could ever have...but nothing: if the array dimension doesn't match the number of columns that i've on my view, i.e. i receive "ora-00947 not enough values" error.
Is there a method to dimension dinamucally the array to store my data? Or should I change the code to fetch some other way the data i need to put to a file?
query to know number of columns in a table i.e.
if I want to know how many number of colums are present in a specific table then what would be the query.
My goal is this:I have a table which is being updated/changed by lay people with certain types of values. Constraints are given to them, but they need not conform to them as they update the table in excel.Now, I want to validate this table every-time before I use it. i.e. implement a script which can be run to verify is all the values are in the right format for further usage.
I have a variable number of columns (i.e. users can add further columns as their requirements change).From columns 3 to 'n' (depending on table given) the values should be 'Yes' or 'No'. How do I check this for a variable number of columns in PL/SQL?
in my oci applications,if i get a column of number that is in the scope of int,i can use value = *(int *)field.data; get the value,but if the column size is larger than 10,the code can't be available,how can i get the value.

But the same i need to achieve in pl/sql. I try with the Ref cursor, but not succeeded.
how to update the middle of plenty rows in the middle of the columns
sample_data
id name state REGION LOC
1 v A.p 1 1
2 a
3 g K.A 0 3
4 y
5 i T.N 1 0
6 l M.P 0 1
7 c U.P
This is sample data,and i have this kind of large data and i need to fill the rows which are empty. In three columns state,region,loc with data like 0,web_intimation,1,
I want to add a variable number of new columns to an existing table temp (with column provided).
Example:
NewColumnNo = 4
-> the columns shall be named rate_1, rate_2, rate_3 and rate_4
-> the values shall be = Column / NewColumnNo
The result shall be like this:
create table temp_res (prodid integer, rate_1 number, rate_2 number, rate_3 number, rate_4 number);
insert into temp_res values(1, 0.25, 0.5, 0.75, 1);
insert into temp_res values(2, 0.25, 0.5, 0.75, 1);
insert into temp_res values(3, 0.25, 0.5, 0.75, 1);
insert into temp_res values(4, 0.25, 0.5, 0.75, 1);
insert into temp_res values(5, 0.25, 0.5, 0.75, 1);
insert into temp_res values(6, 0.25, 0.5, 0.75, 1);
insert into temp_res values(7, 0.25, 0.5, 0.75, 1);
insert into temp_res values(8, 0.25, 0.5, 0.75, 1);
insert into temp_res values(9, 0.25, 0.5, 0.75, 1);
if there is any inbuilt function or way to find a row in the table that is having value for maximum number of columns.
For example, the table A has 5 columns
(c1,c2,c3,c4,c5) and it has 3 records(r1,r2,r3)
and
r1 has values only for c1,c2
r2 has values only for c1,c2,c3,c4
r3 has values only for c1
so I should get the result as "r3 has values for 4 columns & it is not having value for column c5".
I need to write a dynamic SQL in PL SQL to query an unknown number of columns. Let me take a simple example query here:
SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS
If I have known the number of columns, e.g. querying two columns: "FIRST_NAME" and "LAST_NAME", I can write a DYNAMIC SQL based on the template in table 8-2 of URL....
DECLARE
stmt_str varchar2(200);
cur_hdl int;
rows_processed int;
FIRST_NAME varchar2(200);
LAST_NAME varchar2(200);
BEGIN
cur_hdl := dbms_sql.open_cursor; -- open cursor
stmt_str := 'SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS';
[code]....
However, if I wish to write a dynamical sql to query these two columns for a more general purpose (which should meet the requirement to query different number of columns, e.g. three columns, FIRST_NAME, LAST_NAME, BIRTHDAY instead of two columns FIRST_NAME and LAST_NAME). To do this I first try to query the same two columns but using a different method, following URL.....My code for the same query has error, and I cannot solve it.
DECLARE
stmt_str varchar2(200);
cur_hdl int;
rows_processed int;
l_columns dbms_sql.desc_tab;
l_dummy NUMBER;
l_value NUMBER;
[code]....
The below sql is giving different number of result sets while adding further columns in select clause.i.e After adding the columns 4,5,6 in the below query its giving different number of result set.In this case the result set count would be 5.
Before adding the columns 4,5,6,the result set count was 11.
SELECT PAYMENT_METHOD_MAP.NETTINGGROUP_ID,
PAYMENT_METHOD_MAP.CREDITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.DEBITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.AGENT_ID,

My requirement is to concatenate two column values and place them in a new column.I have done it using self join but it limits the purpose,meaning when I have more than 2 values for grouped columns then it won't work.How to make this dynamic,so that for any number of columns grouped,I can concatenate.
SELECT a.co_nm, a.mnfst_nr, a.mnfst_qty,
a.mnfst_nr || ':' || a.mnfst_qty || ';' || b.mnfst_nr || ':'
|| b.mnfst_qty
FROM vw_acao_critical a JOIN vw_acao_critical b
ON a.co_nm = b.co_nm AND a.mnfst_nr = b.mnfst_nr
[code]......
What will be the case when I need to concatenate for more number of values.
like when co_nm has three bahs and manfst_nr and manfst_qty has 3 values for each for bah.and if three are having same_mnfst nr then I should use something dynamic.how to achieve this.

I'm dealing with an ORA-1000 error in a Pro*C application where all the cursors are correctly closed (or so it seems to me).
Here is the code for a simple program which reproduces the problem:
Each cursor is opened in a PL/SQL package:
CREATE OR REPLACE PACKAGE emp_demo_pkg AS
TYPE emp_cur_type IS REF CURSOR;
PROCEDURE open_cur(curs IN OUT emp_cur_type, dept_num IN NUMBER);
END emp_demo_pkg;
[Code]....
While testing the initialization parameter open_cursors is set to 50.
It's my understanding that Oracle doesn't close the cursors until it needs the space for another cursor, which in my test case seems to happen when I enter a value of 50 or bigger for "number of loops". To see how oracle is reusing the cursors, while the test program is running I run SQL*Plus and query v$sesstat for the session that's running the test with the following sentence:
select name, value
from v$sesstat s, v$statname n
where s.statistic# = n.statistic#
and sid = 7
and name like '%cursor%';
Even before I enter a value for number of loops I can see that the session opened 4 cursors and closed 2 of them:
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 4
opened cursors current 2
Entering a value of 5 for number of loops yields
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 11 <----- 7+
opened cursors current 8 <----- 6+
With a value of 30
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 36 <----- 25+ (apparently, Oracle reused at least 5 cursors)
opened cursors current 33 <----- 25+
With a value of 47
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 53 <----- 17+
opened cursors current 50 <----- 17+
Now I reached the upper limit set by the initialization parameter open_cursors.
Entering a value of 48, I get the ORA-1000 error.
ORA-01000: maximum open cursors exceeded
ORA-06512: at "SCOTT.EMP_DEMO
Since I open and close the cursor in the same loop iteration, I expect to find in every iterarion 1 explicit cursor and a number of implicit cursors (the PL/SQL call along with the so-called recursive cursors), but I don't expect the sum of all of them to be greater than 50. If my understanding is correct Oracle should be reusing the 50 cursors previously marked as "closeable", not raising the ORA-1000 error.
Is it possible to:
-define a cursor with bind variables
-get a cursor record from these cursor
-and pass the bind variable in the OPEN clause
Did'nt succeed as shown in the example.

I want to create a report by using one field and one text as columns name in layout but display the all the columns. I mention the 5 column names in query.how can I write function in summary column.
View 4 Replies View RelatedI am running a fairly busy Oracle 10gR2 DB, one of the tables has about 120 columns and this table receives on average 1500 insertions per second. The table is partitioned and the partitioning is based on the most important of the two timestamp columns. There are two timestamps, they hold different times.
Out of these 120 columns, about 15 need to be indexed. Out of the 15 two of them are timestamp, at least one of these two timestamp columns is always in the where clause the queries.
Now the challenge is, the queries we run can have any combination of the 13 other columns + one timestamp. In reality the queries never have more than 7 or 8 columns in the where clause but even if we had only 4 columns in the where clause we would still have the same problem.
So if I create one concatenated index for all these columns it will not be very efficient because after the 4th or 5th column the sorting would no longer be very useful and I believe the optimiser would simply not use the rest of the index. So queries that use the leading columns of the index in sequence work well, but if I need to query the 10th column the I have performance issues.
Now, if I create multiple single column indexes oracle will have to work a lot harder to maintain all these indexes and it will create performance issues (I have tried that). Besides, if I have multiple single column indexes the optimiser will do nested loops twice or three times and will hit only the first few columns of the where clause so I think it will kind of be the same as the long concatenated index.
What I am trying to do is exactly what the Bitmap index would do, it would be very good if I could use the AND condition that a Bitmap index uses. This way I could have N number of single column indexes which the optimiser could pick from and serve the query with exactly the ones it needs. But unfortunately using the Bitmap index here is not an option given the large amount of inserts that I get on this table.
I have been looking for alternatives, I have considered creating multiple shorter concatenated indexes but this still would not address the issue since many queries would still not be served properly and therefore would take a very long time to complete.
What I had in mind would be some sort of multidimensional index, I am not even sure if such thing exists. But essentially it would be some sort of index that could serve a query efficiently regardless of the fact that the where clause has the 1st, 3rd and last columns of the index.
So considering how widely used Oracle is and how many super large databases there are out there, this problem must be common.
just looking around to use the new feature available in oracle 11g to convert the dbms_sql numeric cursor to reference cursor, how to do it?
parse and execute the sql string first with dbms_sql and then convert it to ref cursor?
