Re: Why the data changes it's value by itself!

 For the column: date(varchar 8) '2000606' the
SELECT ascii(substring(date,4,1)) from jnlsale WHERE id_jnlsale=28384
gives: 22
SELECT ascii('6'); gives 54

 For the column: amount(float 8)  1.20932764209866e-307 the
SELECT ascii(substring(amount,20,1)) from jnlsale WHERE id_jnlsale=28382
gives: 48
