Home -> Community -> Mailing Lists -> Oracle-L -> RE: MAX Length of Name for Table / Index ?
All object names are stored in the data dictionary, which are tables (just
like the table you are creating). As such, each column has size
characteristics. Looking at the USER_TABLES view (or USER_INDEX), the NAME
column is defined as VARCHAR2(30). If we look at the views, the table/index
name is derived from sys.obj$.name, which is stored as a VARCHAR2(30). Since
all table/index names must be stored in the data dictionary and only 30
characters are allocated for the storage, the maximum name size is 30
characters.
