Hi,
I'm trying to figure out the size (in bytes) of a DATE column. Executing the
three queries below returned me three different values. Is there any way of
finding the size of a date column in the database?

Thanks.

elain

select * from testing;
DOB

06-OCT-03 desc testing
Name
Null? Type

------------- DOB DATE

select avg_row_len from user_tables where table_name='TESTING'; AVG_ROW_LEN

select data_length from dba_Tab_columns where table_name='TESTING'; DATA_LENGTH

select length (timestamp) from abc;
LENGTH(TIMESTAMP)

                9
