Correct format for identifiers
The maximum length of table owner, table name, object owner, object name, as well as column name identifiers depends on the version and platform of Db2.
When specifying the identifier you can use any normal character.
Normal characters include uppercase letters, digits, or the following
characters: _, @, #, and $. You must enclose any special characters
in quotes. If the identifier includes a quote character, you double
each occurrence of the quote character and then enclose the entire
identifier in quote characters. For example, you enter the identifier pro"ject
as "pro""ject"
.
If you use lowercase letters and do not enclose the identifier in
quotes, any lowercase letters are changed to uppercase.
