Question

I have a VARCHAR field in a MySQL table like so –

CREATE TABLE desc(
    `pk` varchar(10) NOT NULL UNIQUE,
    ...
);

The value in pk field is of the type – (xx0000001, xx0000002, …). But when I insert these into my table the values in pk field get truncated to (xx1, xx2, …).

How to prevent this?

UPDATE: Adding the INSERTstatement

INSERT INTO desc (pk) VALUES ("xx0000001");

Answer 1

It could be that the viewer you are using to LOOK at the values is displaying the info incorrectly because it is trying to interpret that string as a number, or that mysql may be interpreting your numbers as hexadecimal or something strange.

What happens if you do

INSERT INTO desc (pk) VALUES ("xx0000099"); 

Does it come back as xx99? or some other value?
