Hi,
See the Oracle SQL Reference Guide for a description of all the available data types. In short:
varchar2 - Variable-length character string
nvarchar2 - Variable-length character string - use the defined national character set
char - Fixed-length character data (Oracle blank-pads the value to column length)
nchar - Fixed-length character data - use the defined national character set
You can start with the following data types:
1) number
2) varchar2
3) varchar2
Best regards.
Frank
