SQL & PL/SQL :: How To Find Greatest Values In A String
Jul 22, 2011
I am trying to update the greatest value in a column from a string of other column.
Ex: f the value is shown 10M+16M+25M-DG, then populate 25 only
so for that I had written query as follows:
update ANCHOR set IEL_STRAND_SIZE= greatest(
substr
(REPLACE(REPLACE(REGEXP_REPLACE( F_TYP, '[A-Z]', '' ),'+',','),'-',','),
0,
length(REPLACE(REPLACE(REGEXP_REPLACE( F_TYP, '[A-Z]', '' ),'+',','),'-',','))-1))
The output is given as 10,16,25,but not as 25.so how could i write it?Do I need to implement procedure or arrays for it.

I am confused with third one.
CODE1. >> Comparing two strings >>
SQL> select greatest('99' ,'100') from dual;
GR
99
2. >> comparing both numbers >>
SQL> select greatest( 99 ,100) from dual;
GR
100
3.>> Comparing string and number >>
SQL> select greatest('99' ,100) from dual;
GR
99
whats the logic behind 99 being returned for thirdone.

Insert into PROFILE
(INSTANCE, PROFILENAME, USER_DATA, UPDATE_DATE)
Values
(138, 'Test A', 'SRC!-1,ARCHIVE_OPT!-1,DATE_FIELD!155,DATE_RULE!1,DISTINCT!1', TO_DATE('01/20/2005 13:35:33', 'MM/DD/YYYY HH24:MI:SS'));
/
Insert into RULES
(ID, NAME)
Values
(155, 'DATE_TEST');
I want a code something of this sort:
select profilename from PROFILE where user_data like '%DATE_RULE!115%';
Output will be "Test A".Now, this is just a single value from RULES table used to find the data of PROFILE table.I will have to run the query on multiple values of RULES tables to find records containing a string format of sort "DATE_RULE!<rule_no>". How to search on WILD CARDs like these?

SQL> select greatest ( 1000,null) from dual;
GREATEST(1000,NULL)
-------------------
SQL> with t as
2 ( select 1 a from dual union all
3 select null from dual)
4 select max(a) from t;
MAX(A)
----------
1
Why greatest returns null ( as the greatest value among the list of values) as the greatest value while max returns 1 in the above case?

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

I've a table where I've to select the greatest value from each row.
create table find_max ( colA number, colB number, colC number );
insert all
into find_max values (8,12,13)
into find_max values (-1,-22,3)
into find_max values (1,null,13)
into find_max values (-1,-2,-3)
into find_max values (-1,0,-10)
select * from dual;
the desired format of output is:
three fields for colA, colB, colC and max_value
max_value for 1st row is 13, 2nd is 3, 3rd is 13, 4th is -1,5th is 0.
how can I find the max_value without using any built in functions??

I am currently working on a Data Dictionary project where we need to run a few rules against the give data sources to see if they all comply together.
One of the rule is to check if the no. is negative or not. So for that what I tried to do was to check if first the field is number or not and then check on if it is negative or not.
This is the code I am currently trying on and is not looking good.
SELECT 1 FROM DUAL
WHERE decode(DECODE( TRANSLATE('-123.45','-0.123456789',''), NULL, 1,0), 1,substr('-123.45',1,1) ,' ' ) = '-'

Is there a way to find out the ending digits in a string?
Examples of input and outputs:
'ABC123' -> 123
'ABC' -> NULL
'123ABC' -> NULL
'123ABC456' -> 456
'123ABC456QP98' -> 98
I have figured a way to do it by doing Reverse and re-reversing using: reverse(regexp_substr(reverse(p_string), '[ [:digit:]]*'))
But I'm sure there is a way to do it backwards without using reverse function, which I am not able to properly put in the syntax.

I have a requirement, where i need to find and replace values in delimited string. For example, the string is
"GL~1001~157747~FEB-13~ CREDIT~ A~N~ USD~ NULL~".
The 4th column gives month and year. I need to replace it with previous month name. For example:
"GL~1001~ 157747~ JAN-13~ CREDIT~ A~N~USD~NULL~".
I need to do same for last 12 months. I thought of first devide the values and store it in variable and then after replacing it with required value, join it back. I just wanted to know if there is any better way to do it?

I have a table like mentioned below
create table test1( test_no number, test_description varchar2(100));
insert into test1 values (1,'ABC£¥');
insert into test1 values (2,'BCD£¥');
Now I am selecting from the above table and the expected rest it should have shown is as shown below
TEST1
-----------------------
TEST_NO TEST_DESCRIPTION
1 ABC£¥
2 BCD£¥
But instead of showing the extended ascii characters, it is showing some different characters as shown below
select * from test1;
TEST1
-----------------------
TEST_NO TEST_DESCRIPTION
1 ABCLY
2 BCDLY
I have an requirement where i need to fetch the exact ascii characters for £ and ¥ instead of L and Y respectively.

I have data something like this:
Sample DateWITH DATA AS ( SELECT 'AAAXXXX IO BLUEEXPRESS' LIST FROM dual UNION ALL SELECT 'BLUEEXPRESS AAAXXXX IO BLUEEXPRESS' FROM dual UNION ALL SELECT 'DDDDD BLUEEXPRESS AAAXXXX' FROM dual UNION ALL SELECT 'DDDDD DDDDD AAAXXXX' FROM dual UNION ALL SELECT 'DDDDD BLUEEXPRESS AAAXXXX NO CARBON' FROM dual UNION ALL SELECT 'NO CARBON
[code]....
The above result depends on the following rules:
- Replace BLUEEXPRESS into BEXPRESS
- Remove the term NO CARBON (See row no 6)
- Reduce all multiple space into single space (see last record).
So far I create separated queries for replacing BLUEEXPRESS into BEXPRESS and replace NOCARBON term but I don't know how to do it in a single shot as well as stuck on scenario to remove multiple spaces and put single space.

but i want only the distinct values in l_eve_id_str , i.e.,
l_eve_id_str := 9,4,7

I need to extract values from string to variables as below.
declare
str varchar2(100):='Acknowledgment=1234,Order Requester=5678,Site Contact=9999,Other Contact=1456,Pre=1234,23445,56767';

l_s:='9999';
l_ot:='1456';
l_pre:='1234,23445,56767';

str varchar2(100):='Order Requester=5678,Acknowledgment=1234,Site Contact=9999,Other Contact=1456,Pre=1234,23445,56767';

I have a table(PSUSEROBJTYPE) with a long field(PTCUSTFORMAT) containing a row value value in the form:
#1|0|0|0|0|#2|1|0|0|1|#3|1|0|0|0|#4|0|0|0|0
Here, I want to update the above field value to a value in the form:
#2|0|0|0|0|#3|1|0|0|1|#4|1|0|0|0|#5|0|0|0|0
This is nothing but finding each occurrence of (#n) in the above string and replacing it by (#n+1). (i.e #1 is replaced by #2,#2 is replaced by #3).

I have a problem with Between clause used in where statement to compare two string variable.
Query is like this,
select item_code, item_deacrption
from itm_master, invoce_det
where im_code = item_code
AND invd_item_number BETWEEN (:startNum) AND (:endNum)
Here invd_item_number is a DB field and is of type varchar2(41), and (:startNum),(:endNum) are of same type.
now invd_item_number has one value '001003002001'
if we give :startNum = '001003001002' and :endNum = '001003004006'
:startNum and :endNum is composed of separate field values (ie, 1st 3 character shows color code, next 3 for catagory, next 3 for size etc). These codes are entered separately and are combined at run time.
it is still fetching the invd_item_number with value '001003002001'. (the last set of character(type code) in the :startNum is greater than invd_item_number's type code value. But it is smaller than the previous code (size code), that's why it is fetching).
But how can i get around this as i don't need that value to be fetched.
