mysql相似于oracle的to_char() to_date()方法

mysql日期和字符相互转换方法,

date_format(date,'%Y-%m-%d')  -------------->oracle中的to_char();

str_to_date(date,'%Y-%m-%d')    -------------->oracle中的to_date();

sql =     "SELECT *  FROM emp WHERE empno LIKE ? OR ename LIKE ? OR job LIKE ? OR date_format(hiredate,'yyyy-mm-dd') LIKE ? OR sal LIKE ? OR comm LIKE ? limit ?,?" ;
