Pl/SQL coding help

User Interface accepts the Employee information and this data needs to be compared with the existing data and the differences needs to be populated through a Pl/SQL table.

Create a type (EMP_DATA) to populate the Employee table data.
Create a type (ERR_TABLE) with the following attributes:

ERR_NO NUMBER,
ERR_COLUMN VARCHAR2(50),
ERR_RESULT VARCHAR2(500)

Create a package USER5_PKG1 with two procedures.

EMP_CHECK
COMPARE_DATA

COMPARE_DATA takes EMP_DATA as IN PARAMETER and ERR_TABLE as OUT PARAMETER. The procedure should compare the EMP_DATA with the EMP table. The columns that have different values should be added to the ERR_TABLE.

For example,

Table Data
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
7654 MARTIN SALESMAN 7698 20-Feb-81 1250 1400 30
EMP_DATA
7654 MARTIN SALESMAN 7902 20-Feb-81 2000 1800 30

ERR_TABLE
1 JOB Old Value: 7698, New Value: 7902
2 SAL Old Value: 1250 New Value: 2000
3 COMM Old Value: 1400, New Value: 1800

EMP_CHECK should populate the value to the EMP_DATA type and call the COMPARE_DATA and display the results of ERR_TABLE
