Keywords(1)
The SQL contains reserved and non-reserved words. Standards require that reserved keywords not be used as other identifiers. Non-reserved keywords have special meanings only in a specific environment and can be used as identifiers in other environments.
The naming rules for identifiers are as follows:
-
An identifier name can only contain letters, underscores, digits (0-9), and dollar signs ($).
-
An identifier name must start with a letter (a to z) or an underscore (_).
NOTE:- The naming rules are recommended but not mandatory.
- In special cases, double quotation marks can be used to avoid special character errors.
