SQL & PL/SQL :: How To Extract First 3 Characters From Each Word In A String / Sentence And Separate With Underscore
Oct 22, 2013
I have some strings like
'Net Amount Payable by an Individual',
'Net Amount Payable by an Individual+Tax',
'Total Amount Payable towards Service',
'Total Amount Payable towards Service.+Tax'
I need to extract the first three letters from each word and separate them using an underscore. The output should be as follows for the above strings -
I can separate numbers from string (info) and the first value of the string using REGEXP_SUBSTR (see below):
with dat as (select '35263304 Alcatel One Touch 806' info from dual) select info, REGEXP_SUBSTR ( info, '[[:digit:]]+',1 ) tac, REGEXP_SUBSTR ( info, '[[:alpha:]]+',1) brand from dat
But how can I get rest of the values from that string (red color) ?
I just would like to get separately like: 35263304 Alcatel One Touch 806
This I want TO separate TO different COLUMNS based ON comma.
THE RULE IS LIKE out OF total five fields FIRST 3 comma will be FIRST 3 addresses AND rest will be address4 AND LAST NUMBER should appear IN pincode field IF found.
The trouble is for reading reverse to get the number.
WITH address AS (SELECT 'Avenue Supermarts Pvt Ltd,Anjaneya, Opp Hiranandani Foundation School, Powai, Mumbai,Pin Code 400076' addr1 FROM dual UNION ALL SELECT 'Plot No. J-I, Block B-I, Mohan Co-operative Industrial Area, Mathura Road, New Delhi-110044' addr1 FROM dual UNION ALL SELECT 'Padmashree Arcade, NH 5, Chinagantiyda Main Road, Gajuwaka, Vishakhapatnam' addr1 FROM dual UNION ALL SELECT 'The Icon, 2nd 3rd Floor, #8, 80 Feet Road, HAL III Stage, Indiranagar, Banglore-560075' addr1 FROM dual UNION ALL SELECT '13/1, International Airport Road, Bettahalasur Post, Bengaluru-562157' addr1 FROM dual) SELECT addr1 FROM address;
I need to extract the First portion of date entered in remarks column , i have prepared a test as below.
CREATE TABLE LEAVE_DYS (LV_EMP_CODE VARCHAR2(12), LV_DESC VARCHAR2(2000)); INSERT INTO LEAVE_DYS VALUES ('R0754','LEAVE SALARY FOR APRIL 16, 2010 - APRIL 15, 2012 (33 ABSENTS)'); INSERT INTO LEAVE_DYS VALUES ('R0667','LEAVE SALARY FOR JULY 14, 2009 - JULY 13, 2011 (44 ABSENTS)'); INSERT INTO LEAVE_DYS VALUES ('R0841','LEAVE SALARY FOR MAY 29, 2010 - MAY 28, 2012 (NO ABSENT)'); INSERT INTO LEAVE_DYS VALUES ('R0854','LEAVE SALARY FOR MAY 29, 2010 - MAY- 28, 2012 (1 ABSENT)'); [code].....
I have written one program that inserts one field in table item_master based on existing field,for eg, its like old field is 'HEB240x240x10x17x13000mm, S 275 JR' - and i want to replace the 5 digits before mm i.e 13000 needs to be replaced by 6000 or 4000 based on generated values and the new item will be like 'HEB240x240x10x17x6000mm, S 275 JR' or 'HEB240x240x10x17x4000mm, S 275 JR'.
I believe we need to use Translate function to get rid of special characters, But I would not be knowing what sort of special charecters which appear in the string, In that case how do I use Translate?
I need to remove the alpha characters from a string, leaving only numbers, but I am getting unexpected results:
SQL> SELECT TRANSLATE('3N', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', NULL) a FROM DUAL; A -
I thought this would leave the 3 from the 3N, but it is returning an empty string. For my application, the string '3N' could be any length, will only contain letters and numbers, and the letters will always come at the end, but there could be more than one letter
I have a table test with column containing dates, characters and numbers. I have to extract the number part and the three characters before the number . My data looks like :
TEST ID DATA 1 3/12/2007 2 0 3 3/8/2010 ABC 217 4 NONE 5 COLM XYZ 469 6/8/2011 6 LMN 209
I want to tuning the next sql sentence. In this sql I want to get the hash_value and sql_text of the sentences that it's causing TX blocks. Is it possible?. This sentence works fine but sometimes It's slow.
SELECT DISTINCT hash_value, sql_text FROM gv$sql sq WHERE hash_value IN (SELECT DISTINCT prev_hash_value FROM gv$session se WHERE sid IN (SELECT sid FROM gv$lock l WHERE type = 'TX' AND ctime >= 2000 AND l.inst_id = se.inst_id AND l.sid = se.sid) AND sq.inst_id = se.inst_id); [code]....
Is there some way to validate the syntax of sql sentence without actually executing it? I dont want to check if the objects exist or not, just want to check the syntax.
I have a RAC on 9i and I want to know the number of active sessions that it's executing the same sql sentence.I'm using this sql but I'm not sure that this query give me te correct result.
SELECT se.inst_id,se.status,se.SQL_HASH_VALUE,se.USERNAME,substr(sq.SQL_TEXT,1,50) SQL,count(*) FROM GV$SESSION se, gv$sql sq WHERE se.STATUS='ACTIVE' and se.username is not null
create table test ( name varchar2(50), descd varchar2(50) ) insert into test values ('kethlin','da,dad!tyerx'); insert into test values ('tauwatson','#$dfegr'); insert into test values ('jennybrown','fsa!!trtw$ fda'); insert into test values ('tauwatson','#$dfegr ,try');
how do I get the first three characters and last three characters from name field and remove all the junk characters from descd field?
