1. Before you Start
I highly recommend you make a backup of your database prior to running any SQL commands. If you break something, you’ll
want to have a contingency plan.
How To Check Your POBS Table Data in MS SQL Using The
Command-Line
If you’re using Microsoft SQL Express as your Primavera database engine, then you might have also installed the handy
Microsoft SQL Server Management Studio to manage your databases. If you did, you should see it in your Start->All Programs
list in Windows. In case you don’t have SQL Server Management Studio, you can still dig in using the SQLCMD and the
command line.
What we want to do here is to check the POBS table in our Primavera database for entries. If it’s empty, good. If it’s not, then
we’ll clean it up.
1) Open a Command Prompt in Windows.

2. 2) Login to your SQL Express database engine with the following command:
sqlcmd -S server1SQLExpress -U SqlUserAccount -P SqlPassword
On my system, this looks something like this:
sqlcmd -S localhostSQLExpress -U sa -P Prima123Vera
It’s best to login with the “sa” user – hopefully you know the password. You might try “Prima123Vera” if you don’t – it was
used in a lot in install guides.
3) Get a listing of databases on your system
If your login was successful, you should see a prompt that looks like “1>”. That means you’re in.
Let’s get a listing of all of the databases in your install. Type the following at the prompt:

3. SELECT name from sys.databases
Go
These are on separate lines. You should see a list of all of your databases. Now let’s pick one.
4) Set a database to use
Once you’ve identified your database name, you want to tell SQL that you’ll be working inside that db. Type this:
use my_db_name_here
Go
Here’s what you should get in response.
5) Query the POBS Table
To see what data is in the POBS Table, let’s run this query:

4. select * from POBS
Go
If your result was more that 0 rows affected, like mine here, then you’ve got some data in the POBS table that will be affecting
your import / export performance.

Command-Line
Ok, once you’re this far, the cleaning part is easy. Simply run the following command
delete from POBS
Go
That’s it. You’re done and you POBS table is now empty. Make sure to read the recommendations at the end of this article.

5. How To Check Your POBS Table in MS SQL using Management Studio
If you’ve got Microsoft SQL Management Studio or something similar, then follow these steps to clean out your POBS table.
1) Login to Microsoft SQL Management Studio
Make sure to login as the “sa” user using SQL Server Authentication.
2) Find the POBS table
Start by finding your database in the Object Explorer window.

6. Expand the Tables sub-entry and scroll down until your find
“dbo.POBS” which is the POBS table. Highlight the table and click the “New Query” button on the toolbar at the top of the
screen.
3) Check for entries
Type the following in the query window:
select * from POBS

7. Click the “! Execute” button on the toolbar.
You might an empty table or you might see a result like this:

Ok. If you have data, then let’s delete everything from the entire table. It’s a simple command. Type:

8. delete from POBS
Click Execute.
How To Check Your POBS Table Data in Oracle XE
If you’re using Oracle Database Express Edition 10g, aka Oracle XE, the free database that ships with Primavera P6 version 8.x,
then you’ll need to follow these steps to check and clean your POBS table.
1) Open the Database Home Page
Some versions may differ, but I have a Windows program entry in my start menu called “Goto Database Home Page” under the
Oracle Database Express Edition 10g folder. Once you get the home page up in a browser, you’ll need to login with the
appropriate user to access the proper tables.
In this case, you can login with “admuser”. Again hopefully you know the password.

10. 2) Run the SQL command.
From here, you’ll want to access the menu on the large SQL icon and choose “SQL Commands -> Enter Command“.
Once you’ve got a blank command-entry screen loaded, you’ll type in the following:
select * from POBS

11. Then click the Run button. You should now know if your POBS table has any data in it or not. If it does, continue on to the next
section.
How To Clean Your POBS Table Data in Oracle XE
In Oracle XE, deleting entries from the table is very straightforward. In the SQL command window, type in the following:
delete from POBS
Your POBS table should now be empty.
However, with Oracle XE, it’s also necessary to disable 2 triggers by running the following SQL commands – as per Oracle
support. Run each one separately, not together, as you did the delete command.
alter trigger rt_pobs disable
alter trigger rt_pobs_del disable
and now it’s done.
