SQL> create table test (
   2  field1 VARCHAR2(3));

Table created.

SQL> INSERT INTO test
   2  (field1)
   3  VALUES
   4  ('a''a');

1 row created.

SQL> SELECT * FROM test;

FIE
---
a'a

SQL>

try the following in SQL*Plus:

show define

Post the result

If you are not using SQL*Plus then your front-end tool is
defective or needs to be reconfigured.

Might be one of unicode charsets having each symbol more than one byte
and column size defined in bytes not chars. Check DB charset and
whether column is defined as char or byte.

Not in this case. Both "a" and "'" are only one byte long in UTF-8, and
UTF-16 is not a valid database character set.

But you are right that a weird character set might be at fault!

Some gui tools don't take in account characterset semantics and show for 
table created as
create table(field varchar2(1 char) 3 or 4 for the column length 
(depending on characterset). So, the first thing i would ask - how did 
OP come to the conclusion, that field has size 3...

Best regards

Meaning of ':' and '{}'
Hi, Please, can anyone tell me what is meaning of predicates ':' and '{}' ? ---------------- yours Advait Advait wrote: > Hi, > Please, can anyone tell me what is meaning of predicates ':' and '{}' > ? It depends on the context. : is used for module qualification of predicates. Like lists:member(X,L) The curly brackets are used in Definite Clauses Grammars: find the section on DCGs in the manual or google for it and you will find out easily. There are uses of {} as a functor in datastructures also. Cheers Bart Demoen Hello everyone,...

replacement for '{' and '}' ?
I am still playing around with what kind of syntax I would like to mark up my documents. Are there equivalent long substitutes for { and } when they are not used to describe arguments to functions? Something like \begin{group} and \end{group}. In other words, if I could force myself to write, say, \begin{group} \it ... \end{group} instead of {\it ... }, then I believe I could identify from the markup context what is an argument that belongs to a just invoked macro and what is text. {Of course, in this context, \textit{...} would be better.} No more ambiguity whether a in \myfunction{a} i...

'[OFF]' as in 'offensive'???
Hi, given that 'off-topicness' is indicated as '[OT]' and taking a look at those postings that started the threads indicated as '[OFF]' (which may both be seen as being somewhat offensive) may lead to the conclusion that '[OFF]' stands for offensiveness. I don't think that this is the intended meaning so what actually *does* '[OFF]' mean?

'!' vs. '.'
Is there an advantage to using the '!' notation to represent form/ control relationships? (eg. Me!text1 vs Me.text1) I am currently using the '.' notation exclusively (for code completion in the VB Editor), but much of the high-quality code that I've seen (in Duane Hookom's Query-by-Form db, for example) uses the other.
