I have a query like this:
INSERT INTO TAB_AUTOCRCMTREQUESTS
(RequestOrigin, RequestKey, CommentText) VALUES ('Tracker', 'OPM03865_0', '[Orange.Security.OrangePrincipal]
em[u02650791]okok
it's friday!')
As expected it is throwing an error of missing comma, due to this it's friday! which has a single quote.
I want to remove this single quote while inserting using Replace function.
How can this be done?
Reason for error is because of the single Quote. In order to correct it, you shall not remove the single quote instead you need to add one more i.e. you need to make it's friday to it''s friday while inserting.
If you need to replace it for sure, then try the below code :
insert into Blagh values(REPLACE('it''s friday', '''', ''),12);
I would suggest using Oracle q quote.
Example:
INSERT INTO TAB_AUTOCRCMTREQUESTS (RequestOrigin, RequestKey, CommentText)
VALUES ('Tracker', 'OPM03865_0',
q'{[Orange.Security.OrangePrincipal] em[u02650791]okok it's friday!}')
You can read about q quote here.
To shorten this article you will follow this format: q'{your string here}' where "{" represents the starting delimiter, and "}" represents the ending delimiter. Oracle automatically recognizes "paired" delimiters, such as [], {}, (), and <>. If you want to use some other character as your start delimiter and it doesn't have a "natural" partner for termination, you must use the same character for start and end delimiters.
Obviously you can't user [] delimiters because you have this in your queries. I sugest using {} delimiters.
Of course you can use double qoute in it it''s with replace. You can omit last parameter in replace because it isn't mandatory and without it it automatically will remove ' character.
INSERT INTO TAB_AUTOCRCMTREQUESTS (CommentText) VALUES (REPLACE('...it''s friday!', ''''))
Single quotes are escaped by doubling them up
INSERT INTO Blagh VALUES(REPLACE('it''s friday', '''', ''),12);
You can try this, (sorry but I don't know why q'[ ] works)
INSERT INTO TAB_AUTOCRCMTREQUESTS
(RequestOrigin, RequestKey, CommentText) VALUES ('Tracker', 'OPM03865_0', q'[[Orange.Security.OrangePrincipal] em[u02650791]okok it's friday!]')
I just got the q'[] from this link Oracle pl-sql escape character (for a " ' ") - this question could be a possible duplicate

I need to allow only set of characters i.e.,
a to z A to Z 0 to 9 . !##$% *()_=+|[]{}"'';:?/.,-
but When I add dash(-) character to below query it is not working please help me at earliest.
SELECT :p_string FROM dual
WHERE NOT REGEXP_LIKE (translate(:p_string,chr(10)||chr(11)||chr(13), ' '),'[^]^A-Z^a-z^0-9^[^.^{^}^!^#^#^$^%^*^(^)^_^=^+^|^\^{^}^"^''^;^:^?^/^,^-^ ]' );
[.-.] will work fine on this query .
The extra ^ symbols inside the bracket expression in your pattern are not, as I think you expect, negations; only the first ^ inside the brackets does that.
The main issue that is causing, apart from allowing that actual circumflex symbol to be matched when you didn't seem to want it, is that you end up with ^-^ being treated as a range.
To include a literal - it has to be the first or last thing in the brackets; from the docs:
To specify a right bracket (]) in the bracket expression, place it first in the list (after the initial circumflex (^), if any).
To specify a hyphen in the bracket expression, place it first in the list (after the initial circumflex (^), if any), last in the list, or as an ending range point in a range expression.
So as you need to do both, make the hyphen last; you can change your pattern to:
'[^]A-Za-z0-9[.{}!##$%*()_=+|\{}"'';:?/, -]'
You could also skip the tralsnate step by including those special characters in the pattern too:
'[^]A-Za-z0-9[.{}!##$%*()_=+|\{}"'';:?/, '||chr(10)||chr(11)||chr(13)||'-]'
Looks like you need to permit only (7-bit) ASCII characters with exception of ~ and ^
In this case I would try it like this:
WHERE CONVERT(p_string, 'US7ASCII') = p_string
AND NOT REGEXP_LIKE(p_string, '~|\^')
Instead of CONVERT(p_string, 'US7ASCII') = p_string you can also use ASCIISTR(REPLACE(p_string, '\', '/')) = REPLACE(p_string, '\', '/')
I have a table with a column with the structure:
Table name : re_result
res_id
--------------
PSI8765450
PSIRRRRTY781
ABCD000001
I want to fetch the values starting with PSI and ending with 1. My expected output is PSIRRRRTY781.
I am using query
Select * from re_result
Where regexp_like(^PSI*1)
But I am not getting the output. I am getting both PSIRRRRTY781 and ABCD000001.
Plz help
You do not need regular expressions; a simpler LIKE may do the work:
select res_id
from re_result
where res_id like 'PSI%1'
The same thing can be done with regexp:
where regexp_like(res_id, '^PSI(.*)1$')
This matches 'PSI' in the beginning of the string and '1' as last character, just before the end of string ($).
Here you find something more on regexp in Oracle
Another way to handle your query.
SELECT res_id FROM re_result WHERE UPPER(res_id) like UPPER('PSI%1')

There's an age-old saying: "Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems"
Unless you are confronted by a problem that truly requires regular expressions, I'd recommend working with basic string manipulation functions.
Semi-colon:
Use INSTR to find last occurence of '/', call this P1.
Result = Substr from position 1 through P1||';'||substr from P1+1 through to end-of-string
Parameters substitution:
Use INSTR to find where parameter list starts (i.e. find "parameters(" in your string) and ends (presumably the last closing parenthesis ")" in your string). Call these P2 and P3.
Result = substr from 1 through P2 || REPLACE(substr from P2+1 through P3-1,'''','''''''') || substr from P3 to end-of-string
I use Oracle 11g.
My data file looks like below:
1|"\a\ab\"|"do not "clean" needles"|"#"
2|"\b\bg\"|"wall "69" side to end"|"#"
My control file is:
load data
infile 'short.txt'
CONTINUEIF LAST <> '"'
into table "PORTAL"."US_FULL"
fields terminated by "|" OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
(
u_hlevel,
u_fullname NULLIF u_fullname=BLANKS,
u_name char(2000) NULLIF c_name=BLANKS ,
u_no NULLIF u_no=BLANKS
)
While loading data through sqlldr, a .bad file is created and .log file contains error message stating "No terminator found after terminated and enclosed field"
Double quotes starting and ending are not in my data, however I would need double quotes withing the data like in above example surrounding clean and 69. Ex: My data file after loading should look like:
1, \a\ab\, do not "clean" needles, #
2, \b\bg\ , wall "69" side to end , #
How to accomplish this?
Asking your provider to correct the data file may not be an option, but I ultimately found a solution that requires you to update your control file slightly to specify your "enclosed by" character for each field instead of for all fields.
For my case, I had an issue where if [first_name] field came in with double-quotes wrapping a nickname it would not load. (EG: Jonathon "Jon"). In the data file the name was shown as "Jonathon "Jon"" . So the "enclosed by" was throwing an error because there were double quotes around the value and double quotes around part of the value ("Jon"). So instead of specifying that the value should be enclosed by double quotes, I omitted that and just manually removed the quotes from the string.
Load Data
APPEND
INTO TABLE MyDataTable
fields terminated by "," ---- Noticed i omitted the "enclosed by"
TRAILING NULLCOLS
(
column1 enclosed by '"', --- Specified "enclosed by" here for all cols
column2 enclosed by '"',
FIRST_NAME "replace(substr(:FIRST_NAME,2, length(:FIRST_NAME)-2), chr(34) || chr(34), chr(34))", -- Omitted "enclosed by". substr removes doublequotes, replace fixes double quotes showing up twice. chr(34) is charcode for doublequote
column4 enclosed by '"',
column5 enclosed by '"'
)
I'm afraid since the fields are surrounded by double-quotes the double-quotes you want to preserve need to be escaped by adding another double-quote in front like this:
1|"\a\ab\"|"do not ""clean"" needles"|"#"
Alternately if you can get the data without the fields being surrounded by double-quotes, this would work too:
1|\a\ab\|do not "clean" needles|#
If you can't get the data provider to format the data as needed (i.e. search for double-quotes and replace with 2 double-quotes before extracting to the file), you will have to pre-process the file to set up double quotes one of these ways so the data will load as you expect.
I needed to use Oracle 11g's Contains() function to search some exact text contained in some field typed by the user. I was asked not to use the 'like' operator.
According to the Oracle documentation, for everything to work you need to:
Double } characters
Put the whole input between {}
This works in most cases except for a few ones. Below it a test case:
create table theme
(name varchar2(300 char) not null);
insert into theme (name)
values ('a');
insert into theme (name)
values ('b');
insert into theme (name)
values ('a or b');
insert into theme (name)
values ('Pdz344_1_b');
create index name_index on theme(name) indextype is ctxsys.context;
If the 'or' operator was interpreted, I would get all four results, which is hopefully not the case. Now if I run the following, I would expect is to only find 'a or b'.
select * from theme
where contains(name, '{a or b}')>0;
However I also get 'Pdz344_1_b'. But there's no 'a', 'o' not 'r' and I find it very surprising that this text is matched. Is there something I don't get about contains()'s syntax?
CONTAINS is not like LIKE operator at all. Since it using ORACLE TEXT search engine (something like google search), not just string matching.
{} - is an escape marker. Means everything you put inside should be treated as text to escape.
Therefore you issue query to find text that looks like a or b not like a or b.
So your query get matched against Pdz344_1_b because it has b char in it.
Row with only a character ain't matched because a character exists in the default stop list.
Why just b ain't matched? Because your match sequence actually looks like a\ or\ b.
So we have 3 tokens a _or _b (underscores represents spaces). a in stop list, and we have no string _b in the b row, because there only single character. But we do have this combination in the Pdz344_1_b row, because non-alphabetic characters are treated as whitespace. If you remove {} or query for {b or a} then you'll get matches against b as well.
