Title: Case of the Missing Rows

Rick,

    Try the following to see which rows are missing. It the same rows are missing each time, perhaps there is a common thread. If not, well....

 

    After Step 2, do a create table as select or sql*plus copy. This will create a backup version. Do a count(*) from each to make sure the numbers agree.

    After Step 4, select * from table1 minus select * from backup_copy to locate the missing rows.

I have a recurring, repeatable problem I was wondering about its cause.

Oracle 9.2.0.1 on W2K Professional (SP2) Dell Optiplex workstation Pentium 4

Step 1 - I do an SQLLDR process that loads 88640 rows to a table
Step 2 - SQL*Plus session - SELEC COUNT(*) from the table returns 88640 rows
Step 3 - Do an EXP on the table (to allow fall back to this point) - only exports 87257 rows
Step 4 - SQL*Plus session again - SELEC COUNT(*) from the table returns 87257 rows

No one else has access to the database.  There are no unusual entries in the alert log.
There is nothing I have found in the UDUMP or BDUMP directories that would help.

Has anyone else experienced this??

Thanks
