ORA-01756: Quoted String Not Properly Terminated

Question:  I was working on this job and tried to insert values as follows:

insert into posamezna_zival(ID_zivali, Datum_rojstva, Spol, Namestitev, Mati, Oce, Prihod, Odhod, Sorta_FK, Kupec_FK)
values ('SI 9267 9903', 1.4.2010, 'M', 'hlev 4', 'SI 42144700', 'SI 707005', 1.4.2010, 'XXX', 3, 'XXX);

but then I get this error message:

ORA-01756: quoted string not properly terminated 

How do I fix this problem?

Answer:  To diagnose any error, you start by using the oerr utility to display the ORA-01756 error:

ORA-01756: quoted string not properly terminated

Cause: You tried to execute a statement that contained a string that was not surrounded by two single quotes. One of the quotes was entered without the second accompanying quote.

Action: Rewrite the statement so that the string is surrounded by two single quotes.
 

The key is to look for a quoted string that is not properly terminated. Look at your statement and find where you are missing a quotation mark. It's not too hard to spot it.

For example, if you were trying the following:

SELECT author_id, author_name
FROM authors
WHERE author_name = 'Burleson;

You can correct this SQL statement by surrounding the string (ie: Burleson) with two single quotes as follows:

SELECT author_id, author_name
FROM authors
WHERE author_name = 'Burleson';

So, looking back at your statement, it is easy to correct the problem.  Here's the correction, with the addition of a single quotation mark to surround that last string with two single quotes:

insert into posamezna_zival(ID_zivali, Datum_rojstva, Spol, Namestitev, Mati, Oce, Prihod, Odhod, Sorta_FK, Kupec_FK)
values ('SI 9267 9903', 1.4.2010, 'M', 'hlev 4', 'SI 42144700', 'SI 707005', 1.4.2010, 'XXX', 3, 'XXX');
