• Output VARCHAR(32760) String in which all characters where replaced with characters from string 3

Example

 SELECT '(a+ab)-abc*a+b=c' AS ISCORRECT, F_CONVERTSYMBOLS('(1+12)-123*1+2=3', '123', 'abc') FROM RDB$DATABASE;

Expected results:

 ISCORRECT        F_CONVERTSYMBOLS

Example

 SELECT NULL AS ISCORRECT, F_CONVERTSYMBOLS(NULL, NULL, NULL) FROM RDB$DATABASE;

Expected results:
