Like operator functionality

We have a simple select query which is using the 'Like' operator on a char(4) column.
In a oracle windows environment when we have a query such as:
select col1, col2, col3
from table1
where col1 like 'AB'
it returns everything which is = to 'AB' and doesn't seem to be including the trailing 2 spaces as would be stored becasue the column is char(4)
In a oracle unix environment when we the same query:
select col1, col2, col3
from table1
where col1 like 'AB'
it returns nothing...
It appears as if the version running on a windows environment is truncating the trailing 2 spaces when using the like expression but in a unix environment, it is not. Does anybody have any idea or clue what could be occuring or if there is some database setting which could cause this to occur?

Quote from Oracle Doc:
Character Values
Character values are compared using one of these comparison rules:
Blank-padded comparison semantics
Nonpadded comparison semantics
The following sections explain these comparison semantics.
Blank-Padded Comparison Semantics If the two values have different lengths, then Oracle first adds blanks to the end of the shorter one so their lengths are equal. Oracle then compares the values character by character up to the first character that differs. The value with the greater character in the first differing position is considered greater. If two values have no differing characters, then they are considered equal. This rule means that two values are equal if they differ only in the number of trailing blanks. Oracle uses blank-padded comparison semantics only when both values in the comparison are either expressions of datatype CHAR, NCHAR, text literals, or values returned by the USER function.
Nonpadded Comparison Semantics Oracle compares two values character by character up to the first character that differs. The value with the greater character in that position is considered greater. If two values of different length are identical up to the end of the shorter one, then the longer value is considered greater. If two values of equal length have no differing characters, then the values are considered equal. Oracle uses nonpadded comparison semantics whenever one or both values in the comparison have the datatype VARCHAR2 or NVARCHAR2.

Using Like Operator in a decode function

Hi,
I am trying to find out if I can use the like operator in a decode function
like:
select decode(1234,like '%123%','123 is a match') from dual;
this reults in error ORA-00936: missing expression
is there any way to make this work?
thank you

[VB] Like operator not functioning?

I'm trying to create the following statement in my VB code, but I'm getting a "Sub or Function not defined" error. My question is, how do you use the Like operator with InDesign scripting? InDesign doesn't seem to recognize the Like operator.
"myCurrentString" contains a letter.
If myCurrentString Like "[A-z]" Then
End If
I'm also trying to do the following:
If myCurrentDigit Like "[0-9]" Then
End If

I couldn't find "RegExp" in the InDesign script model--could you give a bit more information about what this is? I don't know how to iterate through the contents of an XMLElement as individual character objects, so I'm iterating throught XML.contents, putting each character in a basic string variable. I need a way to put strings into a With statement, or a Like operator. I haven't had success with either technique.
Here's an example:
strTime = myCurrentXMLElement.contents
strTime = Trim(strTime)
strLength = Len(strTime)
For counter = 1 to strLength
strTemp = Mid(strTime, counter, 1)
[This is where I need to find out if strTemp is a letter or a digit]

SQL Query With Like Operator - Performance is very poor - Oracle Apps Table

Hi,
I'm querying one of the Oracle Applications Standard Table. The performance is very slow when like operator is used in the query condition. The query uses a indexed column in the where clause.
The query is..
select * from hz_parties
where upper(party_name) like '%TOY%'
In the above case, It is not using the index and doing full table scan. I have checked the explain plan and the cost is 4496.
select * from hz_parties
where upper(party_name) like 'TOY%'
If I remove the '%' at the begining of the string, the performance is good and it is using the index. In this case, the cost is 5.
Any ideas to improve the performance of the above query. I have to retrieve the records whose name contains the string. I have tried hints to force the use of index. But it is of no use.
Thanks,
Rama

If new indexes are disallowed, not a lot of good ones, no.
If you know what keyword(s) are going to be searched for, a materialized view might help, but I assume that you're searching based on user input. In that case, you'd have to essentially build your own Text index using materialized views, which will almost certainly be less efficient and require more maintenance than the built-in functionality.
There may not be much you could do to affect the query plan in a reasonable way. Depending on the size of the table, how much RAM you're willing to throw at the problem, how your system is administered, and what Oracle Apps requires/ prohibits in terms of database configuration, you might be able to force Oracle to cache this table so that your full table scans are at least more efficient.

How to use like operator in IFTHENELSE (BODS)

Hi All,
I want to find the value of ' % ASSOC%' in the name and replace it to 'Assoc.' using ifthenelse.
Can any one help me. Is there any similar fuction as LIKE operator. Can we give LIKE in ifthen else condition.
Thanks in advance

Hi ,
if you have data ASSOC1,ASSOC2
and you want Output like Assoc.1,Assoc.2.
In this condition it is not possible with ifthenelse function
it will return output as Assoc.
Example Source:
If we use if then else condition. Then it will replace all the Data to Assoc.
Or else if you want to replace ASSOC to Assoc. Then you can use Search_Replace also
it will generate a XML script
The expected output as follows in the below screen. As per your requirement you can you any one of this.

THANX FOR U BUT HOW USE GROUP BY IN THIS QUERY What makes you think there's anything wrong with it?
Are you getting an error message? If so, post the error message.
Are you getting the wrong results? If so, describe.
Whenever you post any code, format it to show the extent of major sections (sub-queries, nested functions, nested anything, multi-part concats, ...
Whenever there's a lot of code between a '(' and its matching ')', put them on separate lines, indent them the same amount, and indent everything in between them at least that much.
Type these 6 characters:

The longer the code is, the more important it is to do this.
It looks like you're doing something like this:

         || M.segment6
-- Need   ) here?That is, the main query is based on an in-line view.
The only columns in that in-line view are debt and credit.
If you want to reference columns like segment1, segemnt2, ... in the main query, then you have to include them in the SELECT clause of the in-line view.
(Since the in-line view is a UNION, remember to include them in both SELECT clauses.)
Table alias M is only defined inside each branch of the UNION. In the main query, you'll reference the columns as segment1, segment2, ...
The following two items may be giving you the right results now, but even if so, they are accidents waiting to happen, and should be fixed.
(1) What is the data type of gl_je_headers.default_effective_date?
If it's a DATE then only compare it to other DATEs. Unfortunately, bind variables can't be DATEs, so you'll have to do something like:

                           AND        TO_DATE (:TO_DATE,   'DD-MON-YYYY')(2) Never mix AND and OR.
You probably need another layer of parentheses somewhere around:

...     AND     (   (     N.user_je_category_name   NOT LIKE 'PAS_%'
              AND     N.user_je_category_name   NOT LIKE 'WS_%'
          OR     N.user_je_category_name   LIKE     'RE_%'
          )It looks like credit will always be 0 (or NULL) in the first branch of the UNION. Is that what you meant?

Issue with like operator

Hi All,
we are using like operator for search functionality (oracle 10G).
could any one help me in handling null, when we use like operator.
Ex:
select empno,ename,d.deptno
from emp e, dept d
where e.deptno = d.deptno
and e.ename like '%JO%';
we have a text box in the front end to key in employee name (ename) or part of ename. when user doesnt use this option, he leaves it blank.
so In the above query, if ename is null then my query fails.
could anybody help me out in handling this scenario.
My query should still give me all the employee ids, if the ename is blank.
using dynamic sql is not advisable.
Thanks

LIKE operator- change symbol for [all characters]

I have an input parameter which contains symbols "*" (star symbol), example:
i_search_par := 'country * street';
I gonna do query:
select * from SearchTable
where col1 like i_search_par;
I want that the "*" would act the same way as "%"-symbol in LIKE operator.
So i want that query would return such results:
'country 1 street'
'country 200 street'
and so on.
What is the better way to achieve this, that "*" is going to be interpreted as a "any number of any symbols"?
Maybe i can say something like:
SET SESSION ANYCHAR SYMBOL = "*".
And after doing that Oracle understands in LIKE operators that star-symbol is like i want?
Or should i really do string replacement by replacing ""%" to "*" in "i_search_par" and in other 30 such varaibles?

Hi,
Sorry, I don't think there's any way to tell LIKE to use different wildcards.

I have ca 30 input parameters:

i_search_par1 := 'country % street';
i_search_par2 := 'country % street';
i_search_par30 := 'country % street';?

And i will use them all like this:
select * from T
where Col1 like i_search_par1
and Col2 like i_search_par2
and
Col30 like i_search_par30You could write a very simple user-defined function. It would be slower, but the query would be a tiny bit simpler:
select * from T
where my_like (Col1, i_search_par1) = 1
and my_like (Col2, i_search_par2) = 1
and my_like (Col30, i_search_par30) = 1
Then you suggest that i sgould do string replacement 30 times for each parameter?Do you mean 1 time for each parameter, or 30 times altogether? Yes.
Isn't there better solution?
Maybe database has instruction that changes interpetation of symbol "*" into "%".It would be handy, but I don't think such a thing exists.

"Like" operator in Framework

Hi,
I was just wondering if there is any operator in OAFramework which is similar to "LIKE" operator in PL/SQL?
Thanks

Actually in my case, i cannot use PLSQL because, in the ReviewPage of my custom page, i need to check the list of all the approvals for which the page goes once submitted. In this process, i had to check for some names, some jobs and add extra information from the page based on the values i get and etc.
But i am glad that i could achieve this functionality with the "regionMatches" function for string. Below is the logic i used.
public boolean XXXMatch(String searchStr, String findStr )
int searchStrLength = searchStr.length();
int findStrLength = findStr.length();
boolean foundIt = false;
for (int i = 0; i <= (searchStrLength - findStrLength); i++)
if (searchStr.regionMatches(i, findStr, 0, findStrLength))
foundIt = true;
return foundIt;
if (!foundIt)
return foundIt;
return foundIt;
To test the above function, In the parameters, if we pass "Hello World how are you" as a parameter value for searchStr and "World" for the parameter value findStr, it will return true.
Thanks

EJB QL "LIKE" OPERATOR NIGHTMARE

i want to pass input parameter to my ejb ql.
it will look like this :
"SELECT OBJECT(p) FROM EntityBeanTable p WHERE p.Title LIKE ?1"
But it seem its imposible with ejb 2.0. am i right ?
how to overcome this then,
"LIKE" operator is so damn important, without this we can't continue our development.
shall we use bmp ? or ????

You can use the like operator with parameters, you just have to put your wildcards into the parameter. Here's an excerpt:
A query that uses a LIKE operator would look something like this:
SELECT DISTINCT OBJECT(user)
FROM User user
WHERE user.userInfo.lastName LIKE ?1
If you check out the code in the code listing on the left-hand side of this panel, you will
note that a method exposes this functionality from the UserManagement session bean
so that you can access it from the client with the getUserByLastNameLike()
method. Thus, to use getUserByLastNameLike(), you can specify the pattern
string as a parameter.
For example, to find users with last names like "High", you would pass the following
parameter value:
users = userMgmt.getUserByLastNameLike("High%");

Select Performance problems using the 'like' operator

I have a PL/SQL procedure that uses a cursor which contains a 'like' operator in the where clause. I have two database instances that are theoretically the same, however this code processes about 100,000 rows in 5 minutes on one database and 100,000 rows in several weeks on the other database. I know it is the 'like' operator that is causing the problem, but I don't know where to look in the database setup parameters as to what could be different between the two. Can someone point me in the right direction?

I tried to think of another way to write the query, but I really need to use the wildcard option on the data I'm searching for. The system I'm working with attaches a suffix to the end of every ID (ie. '214-222-1234-0') The suffix ('-0') increments but the rest of the ID stays the same ('-1','-2',etc...), but I want to find all of the rows where the first 12 characters are the same, so I strip off the suffix and use a wildcard '%' in its place. I tried adding the SUBSTR() function to the left hand column of the where clause, but it was even slower than using the 'like' operator. I know its a sound query, I just can't figure out why it works fine on one database and not the other.

Operator functions or?

Hi all,,
In sqldeveloper ,
I have 2 columns named A and B. column 'A' has data 1 for all rows.
column 'B' has data 12 for all rows. ( ref.below example)
my requirement is that, i need to get 'C' column and the first row of 'C' should be the total of A+B i.e, 1+12 which will give the answer 13.
Next row of column 'C' should retrieve the answer as 14. i.e, answer of 1st row of C's data + 2nd row of A's data and so on for all rows. Do i need to use any operator functions or which method can i achieve this?
eg:
A B C
1 12 13
1 12 14
1 12 15
1 12 16
1 12 17
thanks in advance.

What an odd question.
If it is just A+B from the first row and then cumulatively adding A from the subsequent rows then something along the lines of...

Problem in Adhoc Query's set operation functionality.

Hi Experts,
I am facing problem executing Adhoc Query's set operation functionality.
In Selection Tab, following operations are performed :-
Execute a query and mark it as 'Set A'.(Say Hit list = X)
Execute another query and mark it as 'Set B'.(Say Hit list = Y)
In Set operation Tab, following operations are performed :-:-
Carry out an Operations 'Set A minus Set B'.
which results in Resulting Set = Z.
Transfer the resulting set 'in hit list' and press the copy resulting set button.
In Selection Tab, Hit list is populated with Z.
And when output button is pressed, I get to see 'Y' list and not 'Z' list.
Kindly help.
Thanks.
