How do I enter a Ñ into a varchar?

  • 772

In an Oracle database, I have a table with a field defined as varchar(2), in which I must enter a code (key of the table), but when entering the code 'LÑ' it returns an error, I have used Ñ in another field in the same table.

The table only has these two fields (In the DESCRIPTION field, if I can enter Ñ):

"PROFESSIONID" VARCHAR2(2), 
"DESCRIPTION" VARCHAR2(200),

I do the insertion with this code

INSERT INTO ESQUEMA.TABLA (PROFESSIONID,DESCRIPTION) VALUES ('LÑ','ESTA ES LA DESCRIPCION');

The error it returns is the following.

SQL Error [12899] [72000]: ORA-12899: el valor es demasiado grande para la columna "ESQUEMA"."TABLA"."PROFESSIONID" (real: 3, máximo: 2)

How can I solve that? And why does this error occur?

    In principle, as I understand what the error shows, the character "Ñ" understands it as 2 characters (if you search your own database, you will see that the Ñ is understood as ñ), while the letter "L" or any other standard keyboard letter understands it as only 1 character .

    (That's why I gave it (real: 3, máximo: 2)in your error). If you want to solve it, the easiest thing is to increase the VARCHAR from 2 to 3, and you should have no problem adding more Ñ, being like this:

    "PROFESSIONID" VARCHAR2(3),  "DESCRIPTION" VARCHAR2(200),

    The Ñ is stored in the database as " ñ ", hence it is 2 characters and you must increase it for it to work correctly.

  2. I think the ñ occupies more than one char (there are two chars), so LÑ is too big to put it in a char(2) field.

    You will have to broaden your field.
