You need to select a table from which to start from. Kind of like a central table from which Toad will build the relationships out of your entire ER diagram.

First, try checking which one of your tables is the most adequate to start from.

Second, select how many levels of referential tables do you think should be enough for the whole diagram to display (default value "5" is usually fine).

Third, select your display options. Click "Ok".

That's it.

Select ER diagram and you will get a new menu Database. Next select Reverser engineer. Next just follow the steps by providing the database login credentials. You have to create a DSN first.

How to select ER diagram u mean that we need to select generated ER-diagram from TOAD.But i am unable to generate for whole shema .Only it is getting generated for only one table.could you plz suggest how to go on.

One more thing Is this DNS or TNS ?

the steps i suggested was regarding the use of MSVisio not toad. and you need to create a DSN (data source name).

In TOAD, to generate the ER Diagram, Choose the Schema from the Drop down, and then select a table-> press Shift and scroll down( This will select all the tables in that schema) - then click on the ER Diagram ICON present on the Menu. The Generated ER diagram will have all the tables.

I tried and it worked!
