PLS-00359: assignment target in 'string' must have components
Cause: An assignment target was declared that lacks the components needed to store the assigned values. For example, this error occurs if you try to assign a row of column values to a variable instead of a record, as follows: 

DECLARE 

dept_rec dept%ROWTYPE; 

my_deptno dept.deptno%TYPE; 

... BEGIN SELECT deptno, dname, loc INTO my_deptno -- invalid 

FROM dept WHERE ...
Action: Check the spelling of the names of the assignment target and all its components. Make sure the assignment target is declared with the required components and that the declaration is placed correctly in the block structure.
