Append two values in different tables

[Venky1105]

 Hi All,

Can some one help me with this logic

Table A                                                                               

empID  EmailId                 Product                       

1234     aaa@gmail.com   A,B,C                          

Table B

EmpID   EmailID             Product

1234     aaa@gmail.com   C,D

Join above tables with empid and mailid and update TableA like below

Table A

empID  EmailId                 Product

1234     aaa@gmail.com   A,B,C,D

the values in product should be unique.

UNION ALL both tables, normalize your data using STRTOK_SPLIT_TO_TABLE, apply DISTINCT and denormalize again using RANK/CASE or XMLAGG.

But better fix your data model.
