String literals are delimited with single quotes. A double single quote is an escape notation for a single quote character inside a string literal. Additionally, standard C language escapes are supported. Support of C escapes can be turned off for compatibility with other SQL databases by using the SQL_NO_CHAR_C_ESCAPE option in the configuration file or as an ODBC connection option.
