PL/SQL :: Regular Expression Matching All Given Words
Nov 8, 2012
I'm trying to match all sentences that contain words starting with given search tokens at least once. For example: if the given search token words are one and two then only sentences like "one plus one is two" should match. And should not match sentences like "one plus three is four". I was able to come up with this but I need a AND condition which I'm unable to get it right.
select count(*) from dual where regexp_like('one plus one is two', '(^|s)one|three', 'i');
Currently this gives a count of 1. But needs to give a count of 0 when the regexp is fixed.
search words : one two
one is less than two -> match
two is greater than one -> match
onetwo is union of two numbers -> match
onetwo is union of 2 numbers -> not a match as 'two' is not at the beginning of a word
one is less than three -> not a match as two is not present.

I am having issue with Oracle reserved words, one of the application is using table which has NUMBER as column. I am not able to query that table matching database with NUMBER column.
HERE
select a.*
from DOC a , FOLDER B
where a.NUMBER= B.INCIDENT_ID
and b.open = 'Closed'; I tried double quotes (“”) and sigle quotes too, none of them worked.

Can we use regular expression to eliminate all characters other than -
A to Z
0 to 9
Special characters like - &,%,~,@,#,$,^,*,_,+,=,,/,<,>
Example
String - TEST@#_~````}{!!!12311HELLO
Expected result - TEST@#_~12311HELLO
how we can use regular expression to achieve this result.

I have a Identifier column with start and stop dates along with description .
Two dates are separated by '-'. But the position of that character(-) is not constant always. Depending on the instr function I am able to divide the start and stop dates. But I am getting the performance problem because of huge data
I think the same logic will be implemented by regular expression also . How to write the equivalent logic by using regular expressions
create table REG_EXP_TEST
(
TRANS_ID NUMBER(10),
TRANS_IDENTIFIER VARCHAR2(250)
) ;
insert into REG_EXP_TEST
(TRANS_ID, TRANS_IDENTIFIER)
values
[code].......

Is there a way to perform a pattern check on a value ?
For example: 654321HD9
The pattern is 6 numbers, followed by 2 letters, followed by 1 number. The data type for the attribute is a string.
Examples of right or wrong
654321HD9 - correct value
654321HD - wrong value
654321111 - wrong value
HD1111111 - wong value
The pattern has to be as i mentioned above (6 number, 2 letters, 1 number) otherwise its wrong. My pattern does not cover all cases.
select REGEXP_SUBSTR('654321HD9', '[0-9]+[A-Za-z]+[0-9]+') from dual;

I would like to write a select that would return all places in DB that are commiting transaction.
E.g. package for testing:
CREATE OR REPLACE PACKAGE test.TEST_COMMIT AS
PROCEDURE THE_ONLY_COMMIT_IN_DB ;
END TEST_COMMIT;--not a match
CREATE OR REPLACE PACKAGE BODY test.TEST_COMMIT AS
[code]....
The select should return 4 rows with --ok.
SELECT *
FROM ALL_SOURCE ASO
WHERE
REGEXP_LIKE(ASO.TEXT,'commit(s*);','i' )
AND name = 'TEST_COMMIT'

I need to search a specific pattern from a source code. In word, I need to check whether "getCode" has been called or not, for all the string inside double-quote("). Following are sample code lines -
1.->if(val==23){ month_desc = "a sample data"; }
2.->if(val==23){ month_desc = getCode("a sample data"); }
3.->if(val==23){ month_desc = "a " + getCode("sample data"); }
4.->if(val==23){ month_desc = getCode("sample data"); var2="sample data2";}
Now, expression should be such that it will return true during check for 1, 3 and 4, although, for 3 & 4 getCode has been called for part of the String.

I have given below example.I hope that is clear.
M_STR_1 VARCHAR2(1000);
M_STR_2 VARCHAR2(1000);
BEGIN
M_STR_1 :='CHANDAN,RATTAN,PL,SQL';
M_STR_2 :='PL,SQL,RATTAN,CHANDAN,WINDOWS,LINUX';
--Output should like this same as order of M_STR_1
M_STR_2 :='CHANDAN,RATTAN,PL,SQL,WINDOWS,LINUX';
I think approach should be like take 1st word (before ,)and search the position in M_STR_1
and assign the that position in another variable using ltrim or rtrim. Well this what is i think

When integrating your product with third-party APIs I've repeatedly come into conflict with PLSQL and Oracle's reserved words list. For instance while integrating the clickatell SMS Message Transmission notification API there are two variables they send.
[URL]......
How do you propose PLSQL handles these requests without using Apache to rewrite the variable names, or using the three and four variable pslql variable collection methods.
