Like operator in a query

I need a user to be able to enter a city to pull up results
for that city using a LIKE operator. However, if the master list
contains St. Paul, instead of Saint Paul, how can I get either one
to show up? I've tried several things and I just can't get it to
work!!! Thanks!

I have had code like some below but it slows thing down
because indexes can't be used. Instead for searches that don't have
to be exactly up to date I build a work file that is in a
standardized format nightly but it could be done by triggers. This
code is for Oracle.

CONCATENATE c_5051 c_% INTO l_val1.
CONCATENATE c_5101 c_% INTO l_val2.
SELECT prctr

but it is failing even though ther is an entry in BSEG table satisfying hte given condition.

HI,
u can use like operator in select statement where condition.
may be it is failing because of some other selections. please make sure whether the record with the corresponding selections is available in database or not.

LIKE operator is not working in SQL Query in XML file

Hi Gurus,
LIKE operator is not working in SQL query in XML template.
I am creating a PDF report in ADF using Jdeveloper10g. The XML template is as follows
<?xml version="1.0" encoding="WINDOWS-1252" ?>
<dataTemplate name="catalogDataTemplate" description="Magazine
Catalog" defaultPackage="" Version="1.0">
<parameters>
<parameter name="id" dataType="number" />

</parameters>

</sqlStatement>
</dataQuery>
<dataStructure>
<group name="EmployeeInfo" source="Q1">
<element name="EmployeeName" value="ename" />
<element name="EMPNO" value="empno" />
<element name="JOB" value="job"/>
<element name="MANAGER" value="mgr" />
</group>
</dataStructure>
</dataTemplate>
if i pass the parameter value of :ename from UI, it doesn't filter. But if I give ename = :ename it retrieves the data. Can anyone help me why LIKE operator doesn't work here?
Appreciate your help,

Hi
Well for a start, you are doing some very strange conversions there. For example...
and to_char(a.msd, 'MM/DD/YYYY') != '11/11/2030'
and to_char(a.msd, 'MM/DD/YYYY') != '10/10/2030'If a.msd is a date then you should e converting on the other side ie.
and a.msd != TO_DATE('11/11/2030', 'MM/DD/YYYY')
and a.msd != TO_DATE('10/10/2030', 'MM/DD/YYYY')Also, you may want to take into consideration nothing being input in :P2_ITEM_NUMBER like this...
AND INSTR(a.item_number,NVL(:P2_ITEM_NUMBER,a.item_number)) > 0Is item number actually a number or char field? If it's a number, you want to explicitly convert it to a string for using INSTR like this...
AND INSTR(TO_CHAR(a.item_number),NVL(TO_CHAR(:P2_ITEM_NUMBER),TO_CHAR(a.item_number))) > 0?
Cheers

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 MAKE THAT

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:
{code}
(all small letters, inside curly brackets) before and after sections of formatted text.
The longer the code is, the more important it is to do this.
It looks like you're doing something like this:
Select sum (debt)     debt
,     sum (credit)     credit
from     (
     Select ( SUM (l.ENTERED_DR)
          - SUM (l.ENTERED_CR)
          )               Debt,
          SUM (l.ENTERED_CR)
           - SUM (l.ENTERED_CR)     Credit
     from      gl_code_combinations M,
     where     ...
     AND      H.DEFAULT_EFFECTIVE_DATE BETWEEN :FROM_DATE AND :TO_DATE
     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_%'
GROUP BY M.SEGMENT2
,            (    M.segment1   || '.'
         || M.segment2   || '.'
         || M. segment3 || '.'
         || M.segment4   || '.'
         || M. segment5 || '.'
         || 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      H.DEFAULT_EFFECTIVE_DATE BETWEEN TO_DATE (:FROM_DATE, 'DD-MON-YYYY')
                           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_%'
          )Maybe
...     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?

Filter SharePoint list items using CAML query as same as Like operator in SQL Server.

How do I filter list items using CAML as same as Like operator in SQL.
Please let me know.
Thanks in Advance.

Did you try using <Contains>?

Alternate query to LIKE operator

I have table with contains 65 lakes records, I need to delete the records which does not contains space in column values
Ex : table
Code test_num
NL 123 AP
NL 567ZP
NL 427 SL
NL 456IP
I had return the query like these Delete table A where test_num is not like ‘% %”;
But the problem is the query is getting hang. Because of I am using like operator
Please let me know is there is any alternate query to write
If there any PLSQL to write fetch the query 1laksh records and then delete the records
Deleted rows count is 20Lak

What makes you think so?
It could "hang" (you probably mean "take a long time") due to many other reasons:
- Your system is busy with other stuff and your process gets only partial system resources;
- There is a delete (row) trigger on that table that takes a lot of time;
- The table has many indexes, whose maintenance takes a lot of time;
I doubt it is "because of you using like operator"...

Why the 'LIKE' operator takes so much time to run?

I have a table T with 3 columns and 3 indexes:
CREATE TABLE T
id VARCHAR2(38) NOT NULL,
fid VARCHAR2(38) NOT NULL,
val NVARCHAR2(2000) NOT NULL
ALTER TABLE T ADD (CONSTRAINT pk_t PRIMARY KEY (id,fid));
CREATE INDEX t_fid ON T(fid);
CREATE INDEX t_val ON T(val);
Then I have the following two queries which differ in only one place - the 1st one uses the '=' operator whereas the 2nd uses 'LIKE'. Both queries have the identical execution plan and return one identical row. However, the 1st query takes almost 0 second to execute, and the 2nd one takes more than 12 seconds, on a pretty beefy machine. I had played with the target text, like placing '%' here and/or there, and observed the similar timing every time.
So I am wondering what I should change to make the 'LIKE' operator run as fast as the '=' operator. I know CONTEXT/CATALOG index is a viable approach, but I am just trying to find out if there is a simpler alternative, such as a better use of the index t_val.
1) Query with '=' operator
SELECT id
FROM T
WHERE fid = '{999AE6E4-1ED9-459B-9BB0-45C913668C8C}'
AND val = '3504038055275883124';
2) Query with 'LIKE' operator
SELECT id
FROM T
WHERE fid = '{999AE6E4-1ED9-459B-9BB0-45C913668C8C}'
AND val LIKE '3504038055275883124';
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=1 Card=1 Bytes=99)
1 0 TABLE ACCESS (BY INDEX ROWID) OF 'T' (Cost=1 Card=1 Bytes=99)
2 1 INDEX (RANGE SCAN) OF 'T_VAL' (NON-UNIQUE) (Cost=4 Card=12)

I will for sure try to change the order of the PK and see whether there will be any impact to the performance.
In our application, val is much closer to a unique value than fid. In the example query, the execution plan showed that the index on val was indeed used in the execution of the query. That's why the 1st query took almost no time to return (our table T has more than 6 million rows).
I was hoping the 'LIKE' operator would utilize the t_val index effectively and provide similar performance to the '=' operator. But apparently that's not the case, or needs some tricks.

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.

Problem when using About Operator in Contains Query

Hi,
I'm new to Oracle and this forums too. I have a problem when using about operator in contains query.
I create a table with some records and then create a context index on 'name' column.
CREATE TABLE my_items (
id           NUMBER(10)      NOT NULL,
name         VARCHAR2(200)   NOT NULL,
description VARCHAR2(4000) NOT NULL,
price        NUMBER(7,2)     NOT NULL
ALTER TABLE my_items ADD (
CONSTRAINT my_items_pk PRIMARY KEY (id)
CREATE SEQUENCE my_items_seq;
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Car', 'Car description', 1);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Train', 'Train description', 2);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Japan', 'Japan description', 3);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'China', 'China description', 4);
COMMIT;
EXEC ctx_ddl.create_preference('english_lexer','basic_lexer');
EXEC ctx_ddl.set_attribute('english_lexer','index_themes','yes');
EXEC ctx_ddl.set_attribute('english_lexer','theme_language','english');
CREATE INDEX my_items_name_idx ON my_items(name) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('lexer english_lexer');
EXEC ctx_ddl.sync_index('my_items_name_idx');Then I perform contains query to retrieve record :
SELECT count(*) FROM my_items WHERE contains(name, 'Japan', 1) > 0;
COUNT(*)
      1
SELECT count(*) FROM my_items WHERE contains(name, 'about(Japan)', 1) > 0;
COUNT(*)
      1But the problem is when I using ABOUT operator like in Oracle's English Knowledge Base Category Hierarchy it return 0
SELECT count(*) FROM my_items WHERE contains(name, 'about(Asia)', 1) > 0;
COUNT(*)
      0
SELECT count(*) FROM my_items WHERE contains(name, 'about(transportation)', 1) > 0;
COUNT(*)
      0I can't figure out what 's wrong in my query or in my index.
Any help will be appreciated.
Thanks,
Hieu Nguyen

Hello (and welcome),
You'd be best asking this question in the Oracle Text forum, here:
Text
And by the way, it will help others to analyse if you put {noformat}{noformat} (lowercase code in curly brackets) before and after your code snippets.
Good luck!
