Rules for Oracle 10g schema object names

Rule 1 for Oracle 10g schema object names) except for the database link name, the schema object name can contain a maximum of 128 characters and a maximum of 30 characters. 2) reserved words (such as SELECT) cannot be used as object names. 3) All names must start with A letter from A to Z. 4) The name can only contain letters, numbers, underscores (_), and dollar signs ($) hash symbols (#). 5) lowercase letters are converted to uppercase letters. If the name is enclosed in double quotation marks, you do not need to follow all the above rules (except for the name length). However, when obtaining such an object, you must always use double quotation marks to specify the object. Note that the same constraints apply to the column names. Object names are case sensitive.
