How can oracle tables SQL data compare with each other?

Hi  Garcia  ,

Try the bellows query, may be it will help you

(select * from Table1MINUS select * from Table2) UNION ALL (select * from table2 MINUS select * from table1);

After executing this query  the output will returned few rows , we know that data on both tables have identical . So  rows which will returned by this executing the query present comparison between the table1 and table2 tables.

Thanks

Hello!!

I have got the point of your question. This is very significant to the database admin.

I can give some hints about the solution.    

You can compare your data by sql query. The most effective conditional statement is ‘ SELECT’.

By which you can start filtering your data.

You must use the where clause to filter a data which is to be compared. The WHERE clause

Denotes criteria that will be matched the condition before query.

By query you can compare your sql database tables.
