Would you be so kind to provide an example SQL which shows how to do primary key with a case insensitive collation?

 

Thanks.

This is the default and expected behavior. If you want case insensitive, then you need to create the primary key column with a case insensitive collation.

Hi,

 

It’s been a while since I last used Firebird. I am testing new release candidate at the moment. Just found something I am not so sure.

 

I have a database created using “CharSet WIN1254” parameter.

 

Below is the SQL I used to create a table in that database:

CREATE TABLE KULLANICI

(

  KODU VARCHAR(30)  NOT NULL PRIMARY KEY,

  ADI VARCHAR(50),

  SIFRE VARCHAR(64),

  EMAIL VARCHAR(60),

);

 

And, all below executes without error:

INSERT INTO KULLANICI(KODU) VALUES(‘EK’);

INSERT INTO KULLANICI(KODU) VALUES(‘ek’);

INSERT INTO KULLANICI(KODU) VALUES(‘Ek’);

INSERT INTO KULLANICI(KODU) VALUES(‘eK’);

 

I can insert “EK”, “ek”, “Ek”, and “eK” as new records in the KODU column of that table. Somehow primary key of that table is case-sensitive.

 

I couldn’t find anything about primary key defaults to case-sensitive in the “Firebird-3.0.0_RC2-ReleaseNotes.pdf”. I don’t remember if that was the case in earlier versions, too. Just want to be sure about it. Can anybody confirm if that is a feature?

 

On my part, I would like to avoid it if possible.

Thanks.
