Years ago, someone created a database in Oracle that was carried over and now sits in Oracle 10g. I am developing an application that queries this database and returns the result as XML.
Many (thousands) of rows have an item description that contains an ampersand. I want each of these pieces of data to have it written as & amp; (had to add a space so it would show up here, but you know what I mean) instead of &, but I don't feel like doing thousands of UPDATEs to change this.
Does Oracle have any global find/replace functions that I can call? I'd rather do one update statement that replaces all occurances of & with & amp; but I can't seem to find a function that will do this.
I'm thinking something that would work like:
UPDATE table SET column1=REPLACE(column1,oldstr,newstr);
1 million rows average row length 200 bytes 50 columns and this update statement UPDATE mytable SET varchar2_4000_column = replace(replace(replace...300 times)
It looks at every row in the table (no WHERE clause) and does these 300 replace operations on this column for each row. Each replace replaces with a null so effectively it is removing strings. Much of the time these strings are not in the column.
This update statement takes 25 minutes and it is 98% CPU and 2% USER_IO time.
I figure that is what is taking all the time since it is a CPU bound statement. if rows in this table are persistent over time then tag rows with a flag to show which ones have already been processed and skip these next time around.
I have the next SQL Loader file, and it is giving me some headches because the Replace instruction is not working. It does not replace the ' ' by NULL.
In my project, the below function retrieve output very slowly. Is there any alternative code to replace this function with join
CREATE OR REPLACE FUNCTION f_johnson (i_case_id number,i_seq_num argus_app.case_reference.seq_num%type) RETURN VARCHAR2 AS c_ref VARCHAR2(32500) := null ; CURSOR c_refer IS
I'm using an 'On-Update trigger' to replace the default Form Builder processing for updated records. When I try to change a column in the form I get: ORA- 01446: cannot select ROWID from, or sample, a view with DISTINCT, GROUP BY, etc.
The on-update doesn't fire. How do I get around this. The block is based on a view.
1 - i want to ask few things as i m new to apex, i am using apex 4.1, and created 3 select list and a button in selecting of parameter,
1 select list : select area 2 select list: select product 3- select list - size of the product
i want to generate Ids for the following. for that i created query for INSERTING RECORD FROM ONE TABLE TO ANOTHER , generation the ids when button pressed "Generate" after selecting parameters,
Now where i call that QUERY on button ? because when i create button its gives me option to submit, defined dynamic action, etc, where i call the function name id_generation when button pressed?
2- second thing i created tabular " select user_id, product_name, product_type from product".
By default check box list are create delete submit button are created, first when i insert record it saves that was fine, e.g i entered 50 records and afterward i want to update only one record, e.g there is a record product name = box, if i change it to box small and click submit then it saves all the page means all 50 records,
I want to submit only that record that i changed, for that i use the logic that only those records should be updated which are checked but the user. how will i do this ?
I have a table MOM i.e. Minutes of meeting where important points in a meeting are captured. Now these points may include words like, "don't" or "can't" which will be recorded first in a text file and later copied to the table MOM. Rest of the details are unimportant. All I want to know is how do I enter these words without getting the ORA-01756 error? Do I need to always correct them before entering or is there perhaps another way?
I want to replace numeric values of a specific format with 'X' , find the below example and note that the string in the example only for sample values and the strings may be different.
DROP TABLE test ; CREATE TABLE test (id NUMBER, cnt_str VARCHAR2(200)); INSERT INTO test (id, cnt_str) VALUES (1,'AKRN000002,1451-1473,00000A,74,AKRN000002,1475-14791000000A,8010AKRN000002,1481-1492,00000A,9310AKRN000002,1494-1500')
[code]...
The requirement is in each of the string where there is comma after the number and the number is prefixed by "-" character, the comma after the number should be replaced by '10'.
For example in the second record where ID = 2, CNT_STR is '00000B,1-251000000D,26-32,ADTW000301,2858-2875'. In this string -32, should become -3210 and resulting string should be '00000B,1-251000000D,26-3210ADTW000301,2858-2875'
Expected Result.
ID CNT_STR -------- ------------------------------------- 1 AKRN000002,1451-14731000000A,7410AKRN000002,1475-14791000000A,8010AKRN000002,1481-14921000000A,9310AKRN000002,1494-1500 2 00000B,1-251000000D,26-3210ADTW000301,2858-2875 3 AKRN000001,1126-12001000000B,501-525
1.select store_name, store_id from stores 2.select store_name, (select store_id from inventory where store_id=<somevalue>) from stores 3. select store_name, store_id from stores where store_id in(select store_id from stores1)
based on above examples i need to replace all the columns(oly the column names not the column names in the subquery) in a sql query .
is there is any oracle function to achieve this?
and the result shud be as follows if i replace with STORE_DET.
1.select STORE_DET from stores 2.select STORE_DET from stores 3. select STORE_DET from stores where store_id in(select store_id from stores1)
creating package and i need not to use execute immediate. There are some dynamic build plsql's and sql's stored in global lists. Any other possibility to run them without execute immediate?
I have a string. For example "I have too many files. There are 1000 files. I have to delete them." Sometimes the string can be "I have too many files. There are 115003 files. I have to delete them." Whatever the srting is, I need to change the string to "I have too many files. There are 10 files. I have to delete them." replace the "1000" or "115003" to "10". This portion of the string is always an integer. I use Oracle 11G2.
I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
So many of the queries in our database query by an account but an account is allowed to vary by prefix and so queries are written similar to account like '%suffix'
Our DBA has rejected the use of context indexes and friends to deal with this.
as an aside and I'm probably going to regret going into this much detail but our model is
A->>B->>C
typically the queries want to fetch C's for a customer defined by A.account
A, B, C are all partitioned with partition key created_date
however, only C is typically queried with created_date as a qualifier. A and B are related by joins from A->>B and B->>C
when queries are written to use '%' leading wildcards often it results in a full table scan across multiple partitions. on any given day all we care about are the most recent C's for the customer where customer is defined by A.account.
I recently had an idea whereby fields such as A.Account could also be kept(denormalized) in the C table
the idea is if the queries were written to use C.account like '%bla' instead of A.account like '%bla' then because C is always qualified with the partition key ie. C.created_date that would at worst result in a full partition scan only. this is considerably less expensive than doing a full table scan of A. The IO cost of doing that is huge.
populating the C.account is a simple before insert or update trigger. when you insert a C you have a foreign key to a B and B has a foreign key to A. A and B are always created before any C is seen for any given C. When a C is seen A and B already exist in the database.
I have one emp table, in which i have sal, ename,empno etc columns. Now i am trying to replace each digit of salary with '*'. like if salary is 10000(it has five digit) then it will be replace by *****, but unable to do so. I don't how to achieve this, can we use translate or replace function in this.
Well i have achieved this by using case statement but where hardcoding is done...see the case below:-
select substr(ename,1,8),case when length(sal)=2 then '**' when length(sal)=3 then '***' when length(sal) = 4 then'****' when length(sal)=5 then
I need to create a procedure which inserts values from a temporary table into the main table the columns names in temporary table are same for all temporary tables only the table name will be replaced the skeleton procedure code will look like this.
create or replace procedure load_data as
select c_tables is select table_name from user_tables where table_name like 'TEST%'; V_tbl varchar2(30); BEGIN OPEN C_TABLES; LOOP FETCH C_TABLES INTO V_TBL;
[code].....
The logic here is to insert values from v_tbl variable table into sales_target table.
when I compile it doesn't like using V_TBL variable in the procedure?
I am using regexp_replace function to replace the string between the double quotes with the first occurance but i am able to replace first occurance but I am not getting remaining string.
For example:
select REGEXP_replace('Parent.addChildByName("DS-Id of OAL(BROBA)")||parent.add("DS-Id of OAL(BROBA)")','["]:print:+:punct::print:*["]','XXXX') from DUAL
O/P: Parent.addChildByName(XXXX)
Expected O/P : Parent.addChildByName(XXXX)||parent.add("DS-Id of OAL(BROBA)")
