For example i 'v got a table :

18571!"#$% !"AEOLR% !"Dhrou(Hlvxz'vcpi%&'(#$%&'("#$%&'("#$%&'(Dhrou(Ndwy&uioh$%&'(cbdv$% !"1214541015 !"DLLLWAB"#$% !" !" !" !"/

if the field you are going to insert is a VARCHAR2 type,

in the value, if you have a single quote, you should double it , for example

the insert value is :

sdf'd       -------> sdf''d

if the value contains double quote, you leave as is,  and SQL engine can differentiate it since you will use single quote to enclose the string value.

so you should be able to succeed to insert one like this:

insert into  "GCC"."SGCCSUSR" values('sdfsd''dcd"sdfsd"sdf');

hope this helps

You need to use an escape character (') to enter the data :

a)insert into temp

This will insert it the value -> test'


insert into temp

b)To insert a double quote

insert into temp

All values into the varchar field are to be entered within single quotes. Hence there would be no problem of embedding any doube quotes in to the varchar field.

In case of field values with single quotes, all the single quotes must be repeated twice, i.e for example TEST's must be written as TEST''s.

You can use the String function REPLACE() to do the trick.

Replace(String, '<search>', '<replace>')

Replace(fieldValue, '''', '''''') to get all the single occurences of single quotes to be replaced with 2 occurences of single quotes.

fieldValue = the value that needs to be inserted

parameter2 = '''' (4 single quotes) . You need to enclose the second parameter within single quotes. For example 'A'. As we need to change single quote, you have to enter the single quote twice as the character to be searched for. hence 2 quotes for enclosing the search string and 2 for the search character.

parameter3 = '''''' (6 single quotes) - same as above

I hope this would solve your problem.

I was battling with this as well. There's actually two issues I faced when it comes to the single quotation mark:

1. Using a Select Statement
2. Using an Insert/Update Statement

When using the Select Statement, In VB, I used the Replace function:
Replace(txtTitle, Chr$(39), "''")
Chr$(39) = ASCII Value of a single quote and the replacement string is
double-quote, single-quote, single-quote, double-quote.

When using Insert/Update do the following:
"" & txtTitle & "" - Basically all you are doing is concatenating three strings
First = Empty String
Second = String Literal
Third = Empty String

When I tried replacing a single quote with 2 single quotes, I wound up with 2 single quotes in my literal string, which isn't what you need.

Hopes this helps.

THanks guys,

Much appreciated. Oracle needs extra ' at the end of every ' plus i need to do another trick
with set define x where x is literal not in my character string so i pick ^

1) Insert ' at the end of every ' and run this in SQL*Plus to create a new record

set define '^';
