If you use IF/THEN conditional statements, you must precede nested literal characters with a backslash, referred to as an escape character ( \ ). Adding the backslash ensures the nested literal character is read as part of the string, not the end of the string.
Use the following valid escape characters:
- \\ = \ (backslash)
- \t = tab
- \' = ' (single quote)
Note: To escape a double quote ("), use " " together instead of the backslash. For example,
Address IN (""""), using two double quotes within double quotes.
