What are the suitable datatype for each of below:
1) 123
2) aril

Those are example of data that i would like to store into a table on oracle 9i.

hopefully members' of this forum will help me. thank you.

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.
