PLS-00321: expression 'string' is inappropriate as the left hand side of an assignment statement
Cause: The expression does not designate a variable that can have a value assigned to it. For example, the function SYSDATE cannot appear on the left hand side of an assignment statement such as SYSDATE := '01-JAN-1990';
Action: Correct the illegal assignment statement.

PLS-00321：表达式“ string ”不适合作为赋值语句的左侧,
.原因：表达式不指定可以为其分配值的变量。例如，SYSDATE函数不能出现在赋值语句的左侧，如SYSDATE：= '01-JAN-1990';,
.操作：更正非法赋值语句。,
