Experiment:

Plan the table for the experiment.

Library	User name	User table
A Library	Scott	Emp
B Library	Hyl	Emp

The Scott user does the comparison verification, as follows:

Select the table that you want to compare to, such as:

Add the target user connection as follows:

Start the comparison, as follows:

After the comparison is complete, a modified SQL statement is formed by a comparison of the results, as follows:

There are also several gadgets in the sidebar, such as:

You can view the differences in the table structure by building a table statement, such as:

We execute the "fix statement" below to the target table, as follows:

Again under the Scott user with the hyl user under the EMP table structure to do a comparison, as follows:

We can see that the table structure is no different, as follows:

Summary:

When using PL/SQL Developer to compare the table structures of different libraries and different users under the same table name, the operation is as follows:

tools>compare User objects> selects a SQL modification statement that is generated >target session>compare> than the table.
