Finding location of single quote ( ' ) in a string

Hi,
I have a need to find the location of second single quote in a string.
Below query works fine for a string without single quote. It gives me the location of word 'HIER' for 2nd occurrence.
select instr('HIER A HIER B','HIER',2) from dual
I want to do the same with single quote. I am trying with the below query.
select instr('HIER A '' HIER B ''',chr(39),2) from dual
But it always gives me the location of first occurrence of single quote and not the second.
Any idea about this issue..?
Thanks

select regexp_replace('AND ( ACCT_V.HIER_NODE_NM = ''D0100'' AND TODAYS_DATE IS NULL ','.*''(.*)''.*','\1') from dual
select substr('AND ( ACCT_V.HIER_NODE_NM = ''D0100'' AND TODAYS_DATE IS NULL ',instr('AND ( ACCT_V.HIER_NODE_NM = ''D0100'' AND TODAYS_DATE IS NULL ','''')+1,instr('AND ( ACCT_V.HIER_NODE_NM = ''D0100'' AND TODAYS_DATE IS NULL ','''',1,2)-instr('AND ( ACCT_V.HIER_NODE_NM = ''D0100'' AND TODAYS_DATE IS NULL ','''')-1) from dualComment to the second approach: check SUBSTR() syntax, the second numeric parameter is length of the fragment, not the ending position. Still, RE approach is way shorter and more readable, isn't it? ;)

Single quote in the String????

Hello All,
I want to supress the meaning of single quote in the string, so that I can use the string as one of the fields in my sql query, for doing this inserting "/" before the single code is the way or is there any other standard way to achieve this.
Thanks in Advance,
Sarada.

usually you need to use the scape character for stopping the meaning of a single qoute, or even double quite \', \"
String s = "select empname from emps where id=\'123\'" ;

You need to url-encode the value using the URLEncoder class.
http://java.sun.com/javase/6/docs/api/java/net/URLEncoder.html
For example:
<form name=test action="test.jsp?fname=<%=URLEncoder.encode(name, "ISO-8859-1")%>" method="post">

How to escape a single quotes from a string of dynamic sql clause?

if a single quotes exist in a dynamic sql clause for a string,
like
v_string :='select tname from tab where tabtype='table'',
there tabtype='table' will conflict with the single quote ahead.
could somebody tell me how to escape this single quotes?
thanks for your tips,
frederick

fredrick,
To represent one single quotation mark within a literal, enter two single quotation marks. For example :
v_string :='select tname from tab where tabtype=''table'''

Is it possible to use single quotes in a String

Can we use single quotes and comma in side a string variable...
Eg: String s=" a ' , ' b ";
why am i asking was...... when this variable is sent to database, the table automatically recognizes the beginning single quotes and end single quotes to retreive the value from the table....
Eg for query:
select code from gm_code where sub_code in(?);
when we pass those two value to this query.. it have to execute like the following
select code from gm_code where sub_code in(' a ' , ' b');
but it is not executing.....
can you give me some suggestion to resolve this problem..
Thanks in advance..

You need two strings, and you don't need to provide the single quotes. The driver does that for you when you use PreparedStatment's parameters.
ps = con.prepareStatement("select * from foo where bar in (?, ?)");
ps.setString(1, "a");
ps.setString(2, "b");
rs = ps.executeQuery();The actual SQL that's executed is select * from foo where bar in ('a', 'b')

How do I pass single quotes into a string variable?

Thanks for any help?
Example
Select xdat, yday

where
xdat = to_char(sysdate, 'mm/dd/yyyy')
How do I pass the single quoted stuff above into a string variable?

Thank you but that is not the same thing. I am building a dynamic sql statement and need to pass the quoted material into a statement that is quoted Is that not what my example above shows?
My example above has a quoted string inside a string. I think this is exactly what you were asking for.

How to get a single quote in a string

this is my code, how do i get a * ' * around the :p2_marketingcode so that the result will be

FF change single quotes in query string for their url-encode form (%27) and I need use single quotes (I don't care about derivated security problems)

When I try to enter a url like:
www.example.com?owner=alex's
the actual URL the FF send is:
www.example.com?owner=alex%27s
I need the first option and I don't know hoy to configure it. Could you help me?

I think that RFC1738 is outdated and you should look at RFC3986 section 2.2:<br>
"URI producing applications should percent-encode data octets that correspond to characters in the reserved set unless these characters are specifically allowed by the URI scheme to represent data in that component. If a reserved character is found in a URI component and no delimiting role is known for that character, then it must be interpreted as representing the data octet corresponding to that character's encoding in US-ASCII".<br><br>
I think that in this case there is no special delimiting role or "reserved purpose" for the character to allow the unencoded use. So I think that the behaviour of Firefox is correct.<br>

Copying a table with the right-click menu in schema browser fails to copy comments when string has single quote(s) (ascii chr(39))

Hi,
I'm running 32-bit version of SQL Developer v. 3.2.20.09 build 09.87, and I used the built in context menu (right-clicking from the schema browser) today to copy a table. However, none of the comments copied. When I dug into the PL/SQL that the menu-item is using, I realized that it fails because it doesn't handle single quotes within the comment string.
For example, I have a table named WE_ENROLL_SNAPSHOT that I wanted to copy as WE_ENROLL_SNAPSHOT_V1 (within same schema name)
1. I right-clicked on the object in the schema browser and selected Table > Copy...
2. In the pop-up Copy window, I entered the new table name "WE_ENROLL_SNAPSHOT_V1" and ticked the box for "Include Data" option. -- The PL/SQL that the menu-command is using is in the "SQL" tab of this window. This is what I extracted later for testing the issue after the comments did not copy.
Result: Table and data copied as-expected, but no column or table comments existed.
I examined the PL/SQL block that the pop-up window issued, and saw this:
declare
l_sql varchar2(32767);
c_tab_comment varchar2(32767);
procedure run(p_sql varchar2) as
begin
     execute immediate p_sql;
end;
begin
run('create table "BI_ETL".WE_ENROLL_SNAPSHOT_V1 as select * from "BI_ETL"."WE_ENROLL_SNAPSHOT" where '||11||' = 11');
select comments into c_tab_comment from sys.all_TAB_comments where owner = 'BI_ETL' and table_name = 'WE_ENROLL_SNAPSHOT' and comments is not null;
run('comment on table BI_ETL.WE_ENROLL_SNAPSHOT_V1 is '||''''||c_tab_comment||'''');
for tc in (select column_name from sys.all_tab_cols where owner = 'BI_ETL' and table_name = 'WE_ENROLL_SNAPSHOT')
    loop
   for c in (select comments from sys.all_col_comments where owner = 'BI_ETL' and table_name = 'WE_ENROLL_SNAPSHOT' and column_name=tc.column_name)
   loop
   run ('comment on column BI_ETL.WE_ENROLL_SNAPSHOT_V1.'||tc.column_name||' is '||''''||c.comments||'''');
end loop;
end loop;
EXCEPTION
WHEN OTHERS THEN NULL;
end;
The string of the table comment on WE_ENROLL_SNAPSHOT is this:
WBIG table of frozen, point-in-time snapshots of Enrolled Students by Category/term/pidm. "Category" is historically, and commonly, our CENSUS snapshot; but, can also describe other frequencies, or categorizations, such as: End-of-Term (EOT), etc. Note: Prior to this table existing, Census-snapshots were stored in SATURN.SNAPREG_ALL. All FALL and SPRING term records prior-to-and-including Spring 2013 ('201230') have been migrated into this table -- EXCEPT a few select prior to Fall 2004 (200410) records where there are duplicates on term/pidm. NO Summer snapshots existed in SNAPREG_ALL, but were queried and stored retroactively (including terms prior to Spring 2013) for the purpose of future on-going year-over-year analysis and comparison.
Note the single quotes in the comment: ... ('201230')
So, in the above PL/SQL line 11 grabs this string into "c_tab_comment", but then line 12 fails because of the single quotes. It doesn't know how to end the string because the single quotes in the string are not "escaped", and this messes up the concatenation on line 12. (So, then no other column comments are created either because the block throws an error, and goes to line 22 for the exception and exits.)
When I modify the above PL/SQL as my own anonymous block like this, it is successful:
declare
c_tab_comment VARCHAR2(32767);
begin
SELECT REPLACE(comments,chr(39),chr(39)||chr(39)) INTO c_tab_comment FROM sys.all_TAB_comments WHERE owner = 'BI_ETL'   AND table_name = 'WE_ENROLL_SNAPSHOT' AND comments IS NOT NULL;
EXECUTE IMMEDIATE 'comment on table BI_ETL.WE_ENROLL_SNAPSHOT_V1 is '''||c_tab_comment||'''';
for tc in (select column_name from sys.all_tab_cols where owner = 'BI_ETL' and table_name = 'WE_ENROLL_SNAPSHOT')
    loop
   for c in (select REPLACE(comments,chr(39),chr(39)||chr(39)) comments from sys.all_col_comments where owner = 'BI_ETL' and table_name = 'WE_ENROLL_SNAPSHOT' and column_name=tc.column_name)
   loop
   EXECUTE IMMEDIATE 'comment on column BI_ETL.WE_ENROLL_SNAPSHOT_V1.'||tc.column_name||' is '||''''||c.comments||'''';
end loop;
end loop;
EXCEPTION
WHEN OTHERS THEN NULL;
end;
On lines 4 and 8 I wrapped the "comments" from sys.all_tab_comments and sys.all_col_comments with a replace command finding every chr(39) and replacing with chr(39)||chr(39). (On line 8 I also had to alias the wrapped column as "comments" so line 10 would succeed.)
Is this an issue with SQL Developer? Is there any chance that the menu-items can handle single quotes in comment strings? ... And, of course this makes me wonder which other context menu commands in the tool might have a similar issue.
Thoughts?
thanks//jacob

I know about quick drop, but it isn't helpful here. I want to be able to right click on a string or array wire, navigate to the string or array palette, and select the corresponding "Empty?" comparator. In this case, since I do actually know where those functions live, and I'm already using my mouse to right click on the wire, typing ctrl-space to open quick drop and then typing in the function name is actually more work than navigating to it in the palette. It would just be nice to have it on hand in the location I naturally go to look for it the first time.
I don't agree with this work flow. Right hand on mouse, left hand on home keys. Pressing CTRL + Space is done with the left hands, and then you could assign "ea" to "Empty Array" both of which is accessible with the left hand. Darren posted a bunch of great shortcuts for the right handed developer.
https://decibel.ni.com/content/docs/DOC-20453
This is much faster than waiting for any right click menu navigation, even if it is found in the suggested subpalette.

String with embedded single quote

Hi, all. We're trying to pass a string from one procedure to another, which will then do an EXECUTE IMMEDIATE on it. However, there are single quotes withing the string, and they're driving us nuts! This is what the concatenated string should look like when passed to the pw_execDDL procedure:
insert into appimmunization.wsrprfs (inoc_id, proof, is_valid,proof_num) values ('MEAG', to_date('02-OCT-05','DD-MMM-YY'), 'Y',1);
Here's the concatenation process that doesn't work, and there are functions being called within the string:
chr_sql := 'insert into appimmunization.wsrprfs (inoc_id, proof, is_valid,proof_num) values (' || '''' || prm_inoc_id || '''' || ', ' || 'to_date(' || '''' || prm_proof1 || ''''||','||'''' ||'DD-MMM-YY'||''''||')' || ', ' || '''' || fw_is_proof_valid(prm_birth_date, prm_proof1) || '''' || ',1);';
pw_execDDL(chr_sql); /* call the procedure to do the EXECUTE IMMEDIATE */
Help! We've tried every combination -- using two single quotes together, three, and four, and still no luck. Thanks.

insert into appimmunization.wsrprfs (inoc_id, proof,
is_valid,proof_num) values ('MEAG',
to_date('02-OCT-05','DD-MMM-YY'), 'Y',1);
This statement can be made in a string with the following affectation:
chr_sql := 'insert into appimmunization.wsrprfs (inoc_id, proof, is_valid,proof_num) values (''MEAG'', to_date(''02-OCT-05'',''DD-MMM-YY''), ''Y'',1)';
Note please that each single quote in your original string must be specified using two single quotes and that is all. It is more readable and more easy to do it this way.
Michel.

SQL: Need help putting single quote around string

I want to put single quotes around string in my output.
I am running the following command as a test:
select ' ' hello ' ' from dual;
My expectation is to get 'hello' (Single quote around hello)
However I am getting the following error:
ERROR at line 1:
ORA-00923: FROM keyword not found where expected
When I do SHOW ALL at my SQL command prompt, the escape is set as follows:
escape "\" (hex 5c)
I even tried: select '\'hello\'' from dual;
I get back: select ''hello'' from dual
ERROR at line 1:
ORA-00923: FROM keyword not found where expected

That's true, but they really have to be in a row (no spaces in between), and you still need the single-quotes at the beiginning and end of the literal.
So what you want is
SELECT '''hello'''
FROM dual;Starting in Oracle 10, you can also use Q-notation, For example:
SELECT Q'['hello']'
FROM dual;

Can I quote a single quote character so that I can use it in Replace()

Hi. How can I quote a single quote character so that I can use it in the Replace() function below. I'm attempting to query first_name records that contain a '.
select first_name, last_name
from ttms.prospect
where instr(first_name,"'") > 0
ERROR at line 3:
ORA-00904: "'": invalid identifier

Hi,
String literals are enclosed in single-quotes (not double-quotes).
To use a single-quote within a string literal, use two of them:
WHERE INSTR (first_name, '''') > 0In Oacle 10 (and up) you can also use Q-Notation:
WHERE INSTR (first_name, q'[']') > 0but you may find this more confusing for short literals containing only one single-quote.

SSAS SSRS Report Action on Cell Value w/ Embedded Single Quote Not Executing

I have configured an SSAS 2008 R2 cube SSRS ReportAction. I'm having problems when the member value for a cell has an embedded single quote, e.g. abc's. The action displays on the context menu appropriately, but when I click on the action, nothing happens.
For member values that do not have the single quote, the action works as designed. I've added a calculated ember to escape the embedded single quote by adding another single quote, e.g. abc''s, with no luck. Is there a resolution or workaround for this?

Hi Mdccuber,
According to your description, you create a reporting action in you cube, and it works fine except the members that have embedded single quote, right? In your scenario, it seems that you pass this value to the report as the parameter.
In SQL Server Analysis Services (SSAS), when pass values to a report, multi-select parameters have to be placed into IN statement and SQL Server Reporting Services (SSRS) will do single-quote wrapping for string values automatically. In this case, the original
value that have embedded single quote will be damaged. So this action not work. You can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is resolved in the next release of service pack or product.

Handling single quote

I have a custom function in which I want to parse out any single quotes as they are causing problems further down in our process. Actually what I want the function to do is to find the first single quote, if it exists, then strip the single quote and the rest of the text out. Her is the function I am trying to use:
ifthenelse(
     index($InputText , '\'', 0) > 0,
          substr( $InputText, 0, index( $InputText , '\'', 0) -1),
          $InputText
$InputText is a varchar datatype and contains a sting which may or may not contain an single quote.
How does one look for a single quote in either a function like this or in a replace function?
Thanks,
Ryan

The error in the editor is that is not expecting the less than sign, but rather expecting a right parenthasis ) or a comma.
Error MSG:
[Function:CF_TruncateApostrophe]
(Ln 3) : Syntax error : near <>> found <>> expecting <')', ','>
I will try to encase the whole index statement for the test in parenthesis and see what happens.
