SQL>And as SB said,
1) In oracle you really, really, REALLY don't want mixed case object (column, table, etc) names. Lose the double quotes.
2) don't use reserved words (like 'date') as object names.
also
3) there's no good reason to use CHAR instead of VARCHAR2
4) If you want a date (indicated by your badly named column 'date', make the datatype DATE, not number
5) you need to look at how your NUMBER columns are defined and ask yourself if that's what you really want. NUMBER(1,1) means one digit, with one digit in the decimal location. NUMBER(10,1) means a total of 10 digits, with one of them in the decimal location
