Trying to get a number out of an error backtrack
06512: at "SCHEMA.PROCEDURE", line 4
I only need to take the 4 out of this message. Of course the number might be anything from 1 to 10000.
The database languages might differ so I can't do this using
v_line_no:=SUBSTR(v_line_no,INSTR(v_line_no,'line')+5)
As it would not find any 'line' inside the string.
Assuming I have the following table with its data:
Quote:
| code | description |
| A | $abc + xyz = $cba - 2 |
| B | ($12345 + $12345)/3 |
| C | $poke + $abc = $abc + 456 - 789 |
How can I do a selective search on "description" column for any word that starts with the "$" sign? In the end, this is the resultset that I am expecting:
Quote:
| $ | count of $ |
| $abc | 3 |
| $cba | 1 |
| $12345 | 2 |
| $poke | 1 |
I have one table for eg. TB_Fruits.
In that i have one column FruitsName(Varchar)
In that column i am storing string in comma separated values.
Select FruitsName from tb_fruits;
Result: orange,banana,apple
Now the issue is suppose if i try to insert any of these fruits name again then it should not allow me to insert.
Suppose now if i try to insert ('grapes,banana')
or
('apple,grapes')
the orange,banana,apple can be in any position.
How to check if any of these names already exist or not in the column fruitsname?
I cannot use like or INstr function here. because the position is not fixed not even string.
I want to search for a pattern and replace with a string. I can easily achieve the same in oracle 10g with REGEXP_REPLACE , I want to get the similar solution in 9i.
Eg.
I have to search for a string pattern 1234 5678 9012 6736 , I want to replace the same with XXXX XXXX XXXX XXXX.
My Scenario is'....456re0,50kg400,500rfabs43qre30,25kg150,354rf658....'
there is possible,using regexp_substr or other way to get the values, 0,50 and 400,500 and 30,25 and 150,354? I'm using [^re]+[$kg] and the string comes, but only the first occurence..

if not, that means I have to :

2- edit my report query to something similar to

I've read some documentation about the reverse key indexes, but I haven't understood when really it can be useful use them. when it's smart to use them according to your experiences?

Here is the code
SELECT
from_uom_key,
vip.UOM_KEY,
--DECODE ( from_uom_key,from_uom_key,vip.UOM_KEY,from_uom_key),
[Code]....
difference between the ways we create Reverse Key Index on the table.The two ways are as below:
1) CREATE INDEX <Index_Name> ON <Table_Name>(<Column_Name) REVERSE ;
2) CREATE INDEX <Index_Name> ON<Table_Name>(REVERSE(<Column_Name>)) ;
Which one is the appropraite one.
Are both going to act in the same way.
I created index in both ways one by one on the table.But when I fire the select statement against the same table, The explain plan doesn't show any cost and it shows the full table scan in both ways.The select statement used is as below...I want to compare the column with string RBO(i.e('RBO%') at the start.
SELECT *
FROM <Table_Name>
WHERE REVERSE (<Column_Name>) LIKE '%OBR' ;
The select statement is giving me the correct result. Only the explain plan is showing Full Table Scan.can we use this reverse with IN operator also in the same way by reversing the values.
The Text is displayed correctly when there is no "Arabic comma" ، , otherwise the text will be reversed, How can I avoid the issue, why we have such problem only when we add the comma. The screenshot: s10.postimage.org/8qw1l8621/Arabic_comma.png

Oracle Version: 11gR2: 11.2.0.1.0 - 64bit
OS: Linux Fedora Core 17 X86_64
Currently, I'm reading the online book Oracle Concepts, Chapter 3: 3 Indexes and Index-Organized Tables, section: Reverse Key Indexes in order to understand this topic.
As I understand for each pair of (key, rowid) in the index structure, the rowid for each row in the table obviously remains the same but the bytes of the key are reversed before the key is stored. So for example on a 32 bit machine (just an example) a key = 10 AB CD EF will be stored as FE DC BA 01 , am I right?
According to the documentation, this becomes interesting in RAC environments in order to remove a hot spot from the index (when multiple instances repeatedly modify the same block) with the disadvantage that in some cases there cannot be Index Range Scan any more as data in the index is not sorted by column key when it is stored.
I was just curious to see how bytes of each key are reversed and after a bit googling I found an article where Tom Kyte shows with an example by using dump function (which as I understand gives the internal representation of a given expression) the difference in the sequence of bytes. Here is the link
[URL]
So based on his instructions I tried to do my own test, yet I don't get the same result, that is, the bytes are not reversed for me once we rebuild the index by REVERSE key word.
I'm going to write down here the test that I did, where is/are my error(s)
Test Case:
(I use a copy of the employees table in hr sample schema)
SQL> CREATE TABLE emp_test AS SELECT * FROM hr.employees;
Table created.
SQL> CREATE INDEX emp_test_idx ON emp_test(first_name);
[code]...
Now, a test SQL Query using the index we've just defined (just for giving an example)
SQL> SELECT first_name,
2 dump(first_name, 16) as dump_result
3 FROM emp_test
4 WHERE first_name = 'Kelly';
FIRST_NAME DUMP_RESULT
-------------- ----------------------------------
Kelly Typ=1 Len=5: 4b,65,6c,6c,79
[code]...
So, according to the above Execution plan, Oracle does an Index Range Scan using the index that I defined on my table that is, emp_test_idx. According to the output of dump, the key (first_name) in that index is stored (in terms of bytes) as 4b,65,6c,6c,79
SQL> SELECT chr(to_number('4b', 'xx')) ||
2 chr(to_number('65', 'xx')) ||
3 chr(to_number('6c', 'xx')) ||
4 chr(to_number('6c', 'xx')) ||
5 chr(to_number('79', 'xx')) first_name
6 FROM DUAL;
FIRST_NAME
--------------------
Kelly
Which as we can see corresponds to the first name 'Kelly', the first name we specified in the above SQL query.
Now let's rebuild the index
SQL> ALTER INDEX emp_test_idx REBUILD REVERSE;
Index altered.
SQL>
Once the index keys have been reversed, I run the very same query in order to see the difference
SQL> SELECT first_name,
2 dump(first_name, 16) as dump_result
3 FROM emp_test
4 WHERE first_name = 'Kelly';
[code]...
So the second time after the index has been reversed, I still get the very same sequence of bytes, that is, 4b,65,6c,6c,79, whereas I expected to get 79,6c,6c,65,4b (that is, the reversed order of the initial bytes sequence)
I have this error (and solution):
ORA-02085: database link string connects to string
Cause: a database link connected to a database with a different name. The connection is rejected.
Action: create a database link with the same name as the database it connects to, or set global_names=false.
Where should I set global_names=false ?
I'm facing some problem even after using INSTR function in Oracle.The problem is I have written the logic in the PL/SQL block which appends all the values fetched in a loop on the basis of whether the string is present or not.
For ex:
The first value fetched from the select query first is ABCDEFG which gets appended to a variable
The next value fetched is AB even this has to be appended to the variable since this exactly doesn't match with ABCDEFG.
The next value fetched is BCDEF even this has to be appended to the variable since this exactly doesn't match with ABCDEFG.
The third Value fetched is ABCDEFG this will not get appended presently according to the logic which is correct.
writing that piece of code to append the value fetched which doesn't exactly match with the existing string
show an ex to use string buffer for select statemnt

I would need a SQL script or a command for PLSQL that would search for a keyword %keyword% in all tables of a database instance and in a sepcified schema of a user.
how to do this interactively, without preparing a SQL script with all exisiting tables?
I have an application which deploys the data to Oracle database. It has more than 25 tables and many columns. It does not have any document explaining the deployment, so I am kind of doing reverse engineering here.
I need a script which will fetch the column name or at least table names which will match with either some string or number? I found few examples on net to find out number. But I am struggling to make it work for string.
I can not work on stored proc, as I do not have access to create that on server. So, any script will work.

I'm trying to select from table "A" where value1 and value2 match. If the values are not in table "A", try table "B". If the values exist in BOTH tables - only look at the results from table "A".
Table "A" may or may not have "new" data coming into the system.
Table "B" may or may not have "existing" data.
The code I am writing needs to find the "newest" data row for value1 and value2. Eventually the data in table "A" gets "Merged" into table "B" further on in the process.
Supposedly this can be done in a single query using a left outer join and the NVL function, but the person I inherited this from isn't available.
I've been able to get the row back if it exists in "A" or "B", but end up with two rows or no rows if the row exists in both... Arrrg...
