While trying to trace the execution plan of any script, I get the following message :

>set autotrace on
>select count(*) from mem_item;


Execution Plan
ORA-01438: value larger than specified precision allows for this column

Error generating AUTOTRACE EXPLAIN report

0 recursive calls
3 db block gets

242 bytes sent via SQL*Net to client
425 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
0 sorts (memory)

Does any one know what is causing this ?

Thanks in advance.

Happy coding.
