instead of apostrophe?
we checked Like this:

Begin
For tableList In (Select Owner, Table_Name From All_Tables
Where Owner IN(('WMOS_ARCHB'))
and temporary = 'N'
Order By Owner, Table_Name)
Loop
dbms_stats.gather_table_stats('tableList.Owner',
"tableList.Table_Name",
estimate_percent=>100,
method_opt => 'for all columns size auto',
cascade => true);
End Loop;
End;



SQL> exec dbms_stats.gather_table_stats(null,'"TEST TEST"');

PL/SQL procedure successfully completed.

But Since we are taking the table list through the variable “tableList” it doesn’t work..
