"Stored value cannot be used as non-quoted identifier "
Error when restoring and upgrading projects in ALM 11.5x and later.

Sample error message:

com.hp.alm.platform.exception.CTdException
Messages:
Failed to Restore Project; Failed to restore project; Failed to add project 'hello' to the database; Project database name '2014_10_hello_test' will be stored as '2014_10_hello_test'. Stored value cannot be used as non-quoted identifier.;

Root cause:
non-quoted identifier is invalid.

Fix:
non-quoted identifier should be a valid identifier.

Example:

•    Not recommended to have first letter as Numeric.
•    Not recommend to have @ or # as first letter, as Identifiers that start with @or a number sign have special meanings
•    Identifier must not be a Transact-SQL reserved word
•    Embedded spaces or special characters are not allowed
