I have a problem which i need to solve urgently. Kindly help.

I am using a select statement which substitutes where condition depending on user input like:

select <col>
from <tbl_name>
where &where_clause

The value of this where_clause is obtained from a pl/sql block which has the following line for this:

:where_clause := ' AND f1.category = ''' || :CODE||'''' ;

And user needs to enter the value of CODE variable. And code value is not just numbers, it
includes single quotes also lets say ABTF's, SD, RA's and so on.
The problem is:
If user enter anything which has a single qoutes then this statement wont work.
and it gives error: Quoted string not properly terminated.
For ex:
If user enter RA's then this time it gives an error.

We are using oracle 9 so i cant use regular expressions and neither can i implement q' method.

Can you tell me what can i do in this case so as when value is substituted in where clause it wont give this error??
Is pattern matching possible here??

Kindly help..

You should better post the actual (and format it as requested in OraFAQ Forum Guide as "&where_clause" and ":where_clause" are 2 different things.

In addition, generally speaking, "' AND f1.category = ''' || :CODE||''''" is silly, if you use bind variables you don't concatenate them in a string.
