Incorrect SELECT statement with single quotes

I am getting the following error trying to select a value from a database:
SQLException caught: [Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'mod='Payroll''. Couldn't load driver:[Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'mod='Payroll''.
Here is the select statement code:
PreparedStatement ps = con.prepareStatement("SELECT username FROM experts WHERE mod='"+mod+"'");
I have tried all kinds of variations with the quotes, and single quotes but still get the same error...I know I'm on the right track but I can't seem to spot the error and was hoping someone else could??
thanks in advance,
chuk

Hi,
I tried that and now I get an even stranger syntax error which says "Syntax error (missing operator) in query expression 'mod=Pa_RaM000'."
any ideas?

Dynamic SQL and Data with Single Quotes in it.

Hi There,
I have a problem in that I am using dynamic SQL and it happens that one of the columns does contain single quotes (') in it as part of the data. This causes the resultant dynamic SQL to get confused as the single quote that is part of the data is taken to mean end of sting, when in fact its part of the data. This leaves out a dangling single quote that was meant to enclose the string. Here is my dynamic SQL and the result of the parsed SQL that I have captured:
****Dynamic SQL*****
l_sql:='select NOTE_TEMPLATE_ID '||
'FROM TMP_NOTE_TEMPLATE_VALUES '||
'where TRIM(LEGACY_NOTE_CODE)='''||trim(fp_note_code)||''' '||
'and TRIM(DISPLAY_VALUE)='''||trim(fp_note_text)||''' ';
execute immediate l_sql INTO l_note_template_id;
Because the column DISPLAY_VALUE contains data with single quotes, the resultant SQL is:
******PARSED SQL************
select NOTE_TEMPLATE_ID
FROM TMP_NOTE_TEMPLATE_VALUES
where TRIM(LEGACY_NOTE_CODE)='INQ' and TRIM(DISPLAY_VALUE)='Cont'd'
And the problem lies with the single quote between teh characters t and d in the data field for DISPLAY_ITEM. How can I handle this?
Many thanks,

I have been reliably informed that if one doesn't enclose char/varchar2 data items in quotes, the right indices may not be usedI am into oracle for past 4 years and for the first time i am hearing this.
Your reliable source is just wrong. Bind variables are variables that store your value and which are used in SQL. They are the proper way to use values in your SQL. By default all variables in PL/SQL is bind variable.
When you can do some thing in just straight SQL just do it. Dynamic SQL does not make any sense to me here.
Thanks,
Karthick.

How to deal with single quote (') in a field value?

I can successfully insert value with single quoet using
Prepared statement with placeholder(?) construct .
I can also successfuly use value with single quote(') in
WHERE clause.
My question is, is there a way to use string with single
quote if a Statement like:
String slqString ="INSERT INTO customers (name, address) VALUES ( 'O'Reilly Bob', 'St Mary's Street') ";
Statement sqlStmt = con.createStatement();
sqlStmt.executeUpdate(sqlString);
The last statement will thow an SQLException because due to single quotes
Any ideas?

I think the question was regarding the ' in O'Reily. Use ' twice when using the Statement interface, i.e.
("O''Reilly Bob", "St Mary''s Street")
So that's two single quotes, not a double quote, to successfully insert a single quote, if you know what I mean....
But like you said PreparedStatement does things like this for you.

IN operator with single quotes

Hi All,
I am having problem dealing with Single Quotes with IN operator. Below procedure will explain my problem:
create or replace procedure sp_countemp
p_empnames       in   varchar2
is
v_cnt            integer:=0;
BEGIN
select count(*) into v_cnt from emp where ename in (p_empnames);
DBMS_OUTPUT.PUT_LINE(v_cnt);
END;I will be getting p_empnames as 'ALLEN','SMITH'
But I am not getting any records here.
Thanks,
Danish

Hope this helps..
DECLARE
TYPE strarray IS TABLE OF VARCHAR2(100);
p_empnames STRARRAY;
v_tot INTEGER :=0;
v_cnt INTEGER := 0;
BEGIN
p_empnames := strarray('Allen','Smith');
FOR i IN p_empnames.FIRST .. p_empnames.LAST LOOP
      SELECT COUNT(*) INTO v_tot FROM emp WHERE ename = p_empnames(i);
      v_cnt := v_cnt + v_tot;
END LOOP;
DBMS_OUTPUT.PUT_LINE('Count '||v_cnt);
END;

Importing excel files - problem with single quote

When importing excel files using 1.5, I can't get data with single quotes (') imported.
When I run the insert statement given in SQLPlus I get "ORA-01756: quoted string not properly terminated", which is different than the error that SQL Developer gives me (see below).
Also, I have a numeric value shown without a thousands comma-separator in the XLS file that I'm trying to load into a varchar2 field. But, the insert statements have added a thousands comma-separator which I don't want.
REM Error starting at line 1 in command:
REM INSERT INTO table (ID, NAME, CODE)
REM VALUES (2427407, 'Ed-u-care Children's Center', '73,000');
REM Error at Command Line:2 Column:37
REM Error report:
REM SQL Error: ORA-00917: missing comma
REM 00917. 00000 - "missing comma"
REM *Cause:
REM *Action:
One last thing, TOAD gives a way to automap columns chosen from XLS to the columns in the database. It sure would be nice to have this functionality in SQL Developer.
Thanks,
Steve

Did you consider both to be bugs (i.e., single quote issue and thousands comma separator issue)?
Thanks

A Select statement with Appending table statement in it.

Hi,
How can I use a select statement with a <Appening table> statement in it.
SELECT DISTINCT <field Name>
                FROM <DB table name>
                APPENDING TABLE <itab>
                WHERE <fieldname> EQ <Itab1-fieldname>
                  AND <fieldname> EQ <itab2-fieldname>.
Can I use the above select statement.If I'm using this...how this works?
Regards
Dharmaraju

Hi, Dharma Raju Kondeti.
I found this in the SAP online help, hope this can help you.
Specifying Internal Tables
When you read several lines of a database table, you can place them in an internal table. To do this, use the following in the INTO clause:
SELECT ... INTO|APPENDING [CORRESPONDING FIELDS OF] TABLE <itab>
                          [PACKAGE SIZE <n>] ...
The same applies to the line type of <itab>, the way in which the data for a line of the database table are assigned to a table line, and the CORRESPONDING FIELDS addition as for flat work areas (see above).
The internal table is filled with all of the lines of the selection. When you use INTO, all existing lines in the table are deleted. When you use APPENDING; the new lines are added to the existing internal table <itab>. With APPENDING, the system adds the lines to the internal table appropriately for the table type. Fields in the internal table not affected by the selection are filled with initial values.
If you use the PACKAGE SIZE addition, the lines of the selection are not written into the internal table at once, but in packets. You can define packets of <n> lines that are written one after the other into the internal table. If you use INTO, each packet replaces the preceding one. If you use APPENDING, the packets are inserted one after the other. This is only possible in a loop that ends with ENDSELECT. Outside the SELECT loop, the contents of the internal table are undetermined. You must process the selected lines within the loop.

feng.

Firefox is replacing double quotes with single quotes.

In WordPress and at other sites where I input and save text, Firefox is replacing double quotes with single quotes when I save. It's also showing double quotes as single quotes on websites. I tried uninstalling and reinstalling, and it's still happening.

Do you have the needed font installed?

Problem with single quote when exporting insert statement

Hi
I'm using Oracle SQL Developer 2.1.1.64 on Ubuntu 10.04. I got some records which has single quote in it.
For example,
Let says Table '*TABLE_A*' has varchar2 column called '*COL_A*'.
And there is only one record in the table and the value is:
his friend's dog name is dog.
When I export that table data to insert statement, i got this:
Insert into TABLE_A (COL_A) VALUES ('his friend's dog name is dog.');
As you can see friend's is wrong, it should be friend''s instead. (note the double single quotes).
Anyone knows how to fix this please?

Yes - that's a bug. But probably not what you're expecting.
Mind you really can't use "normal" SQL on LOBs, because they're just too big to fit in the statements.
You should export and import them through e.g. the DBMS_LOB package.
I do remember some request on the SQL Developer Exchange to automate this, so go vote there to add weight for future implementation.
So the bug is that the column's fields should all yield NULL inside the INSERTs.

K.

Passing value in procedure with single quotes intact

HI,
I have the following procedure.
create or replace procedure p1( a varchar2) is
begin
execute immediate ' update emp set sal = 20*Sal + sal
where ename like ' || a;
end;
when I try to run this and pass a value to a. the single quotes
r removed and the entire string becomes.
'update emp set sal = 20*sal + sal where ename like scott'
hence the error.
now my problem is how can i make sure the scott goes like 'scott'
i.e the single quotes are intact. or otherwise 'scott%'
thanx in advance

You can also use triple quotes to do this. the effects of
multiple quotes can be seen below. The same stuff works in

How to handle XML string with Single Quotes as a parameter to SP dynamically?

Hi,
I would like to know if there is a way to handle the Single Quotes in XML value when it is passed to Stored Procedure?
I should be able to handle it without adding another Single Quote to it.
Thanks,
Chandra Shekar

Hi Chandra,
Your requirement is not precise. Based on my understanding and guessing, are you metioning something like the below sample?
/*If the xml is generated you have no need to escape the singe quote(')*/
DECLARE @xmlTbl TABLE (ID INT,name VARCHAR(99));
INSERT INTO @xmlTbl VALUES(1,'Eric''s')
INSERT INTO @xmlTbl VALUES(2,'Zhang''s')
DECLARE @xmlDoc1 XML
SELECT @xmlDoc1
FROM @xmlTbl FOR XML PATH('PERSON'),ROOT('PERSONS')
EXEC yourProcedure @xmlDoc1
/*If your copy and paste the xml, you have to escape the single quote(') with 2s('')*/
DECLARE @xmlDoc2 XML
SET @xmlDoc2 = '<PERSONS>
<PERSON>
<ID>1</ID>
<name>Eric''s</name>
</PERSON>
<PERSON>
<ID>2</ID>
<name>Zhang''s</name>
</PERSON>
</PERSONS>'
EXEC yourProcedure @xmlDoc2
If that is not regarding your requirement, please elaborate with more details.

SELECT statement with 'IN'

Hi,
If SELECT statement has IN in the where clause, does that use the index?
For example,
SELECT t1 f2 f4 from ztest
WHERE
              fid IN     s_id    AND
              doctype     IN s_doctype AND
              year     IN s_year    .
What is the other option to optimize the SELECT with IN?

Replacing " (double quote) with ' (single quote)

Hi there,
I have the following method to manipulate user input. All I want to do is, to replace the double quote with a single quote. The implementation I tried was,
this.replace(desc, "\"", "'");
This does not work for me. It jsut removes the double quote and does not introduces the single quote. Could any one please advise?
Thanks,
Des
public static String replace(String line, String oldString, String newString) {
          if(line != null && oldString != null && newString != null) {
               int index = 0;
               while ((index = line.indexOf(oldString, index)) >= 0) {
                    line = line.substring(0, index) +
                         newString +
                         line.substring(index + oldString.length());
                    index += newString.length();
          return line;
     }

Bad luck.. I am unable to get it still.
This is the code I am using (implemetation is in a JSP. I am using this code to test it).
public class Test{
public static void main(String args[]){
     String s = args[0];
     Test t = new Test();
     String doubleQuote = "\"";
     System.out.println(" output :"+ t.replace(s,doubleQuote,"'"));
     //System.out.println(" output :"+ t.replace(s,"\"","'"));
     //System.out.println(" output :"+ t.replace('"', '\''));
public static String replace(String line, String oldString, String newString) {
          if(line != null && oldString != null && newString != null) {
               int index = 0;
               while ((index = line.indexOf(oldString, index)) >= 0) {
                         System.out.println(" line count :");
                    line = line.substring(0, index) +
                         newString +
                         line.substring(index + oldString.length());
                    index += newString.length();
          return line;
}mshn02
The main problem is I am stuck with the server's version of Java (which I have no control on it). I could not use 1.4.2
