<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve just realised we’ve had a behaviour change on the syntax rules on specifying tables to a query.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The manual (now) says:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt;text-autospace:none"><span style="font-size:12.0pt;font-family:TimesNewRomanPSMT;color:red">To select data from a table you own, specify the name. To select data from a table you do not own,<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:36.0pt"><span style="font-size:12.0pt;font-family:TimesNewRomanPSMT;color:red">specify
</span><i><span style="font-size:12.0pt;font-family:"Times New Roman","serif";color:red">schema.table</span></i><span style="font-size:12.0pt;font-family:TimesNewRomanPSMT;color:red">, where
</span><i><span style="font-size:12.0pt;font-family:"Times New Roman","serif";color:red">schema
</span></i><span style="font-size:12.0pt;font-family:TimesNewRomanPSMT;color:red">is the name of the user that owns the table. However, if the
<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:36.0pt"><span style="font-size:12.0pt;font-family:TimesNewRomanPSMT;color:red">table is owned by the database DBA, the schema qualifier is not required.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:TimesNewRomanPSMT"><o:p> </o:p></span></p>
<p class="MsoNormal">And that is definitely how 11.1 work.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But in 10.1 and 10.2 I know for a fact that if the session was established with a specific (not default) groupname then the user could also drop the schema qualifier from a non dba owned table as well.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Eg. In database ddd owned by user downer, a user u1 has a table t1 on which they have granted group g1 select access.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Another user (u2) connects to the database specifying the –Gg1 connection attribute.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">They select * from t1;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In 10.1 and 10.2 the user would get data from u1.t1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In 11.1 the query fails with E_US0845 Table 't1' does not exist or is not owned by you.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The trouble is that it appears we’ve built an app which relied upon the old behaviour.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I don’t think this is a bug. Even though in our case there is no possibility of confusion on the many possible schema.t1s as each has a unique group associated with it, nonetheless I think it was a poor initial choice and we should code
our way out of it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What are peoples thoughts?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
