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

&reftitle.returnvalues;
A string containing the escaped data.
