<br /> Dear all ,<br /><br /> Would like to receive your kind attention and enormous knowledge on the following<br
/><br/> I have a function<br /> sai_func_a()<br /> Which does as follows and in the same order:<br /> 1. Retrieves the
latestrecord from the table test_sai<br /> (By latest I mean the record corresponding to max primary key of the
table)<br/> 2. Increments date as received from test_sai.current_date<br /> as my_new_date := test_sai.current_date
+1 ;<br /> 3. Inserts the new date into the same table test_sai<br /> 4. Calls another function sai_func_b()<br />
Nowinside sai_func_b()<br /> 1. Does as #1 of above<br /> 2. Works on the date in the last record.<br /> 3.
Returnssuccess code to sai_func_a()<br /> 5. The sai_func_a() finishes the work<br /><br /> Now My question :<br />
Sincesai_func_a() which encapsulates the function sai_func_b has not completed yet till #4 or #5<br /> then how does
thefunction sai_func_b reads the new data since it is not committed yet.<br /><br /> If I am not wrong PostgreSQL
selectstatements works on committed data thus the new<br /> inserted data at #3 must not be available to sai_func_b()
till#5<br /><br /> Server Specs:<br /> 1. version<br />

PostgreSQL7.3.4 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)<br /> 2.Both
functionsare plpgsql and are not triggers<br /><br /><br /><br /> If you need more information kindly ask for the
same.<br/><br /><br /><br /><pre class="moz-signature" cols="72">--
