Escapes a string for use as an SQL identifier, such as a table, column, or function name.
16+
This is useful when a user-supplied identifier might contain special characters
17+
that would otherwise not be interpreted as part of the identifier by the SQL parser,
18+
or when the identifier might contain upper case characters whose case should be preserved.
