    <p>I have a stored procedure with dynamic SQL that creates a table and calls another procedure to insert some values into the table. The stored procedure also sets some session settings, one of which is the <code>NLS_DATE_FORMAT</code>.</p> <p>This parameter is not working when the procedure runs. I've tried running the procedure under <code>SYSTEM</code> (the owner) and under a user <code>ADMIN</code> with DBA, Connect, and Resource privileges, but it always shows up in the format <code>DD-MON-RR</code> instead of the desired <code>MM/DD/YYYY</code>. In SQL Developer, under DBA->Database Configuration->Current Database Properties, <code>NLS_DATE_FORMAT</code> also appears in the format <code>DD-MON-RR</code>.</p> <p>Is there any way to change this for the entire database? I found and tried the following, but it didn't work at all (this includes stopping and restarting the database):</p> <pre><code>ALTER SYSTEM SET NLS_DATE_FORMAT = 'MM/DD/YYYY' SCOPE=SPFILE; </code></pre> <p>I've looked into the SPFILE and init.ora for answers, but the best I found was a trigger that would set the value after logon for each user. I'm not opposed to this, but I would like to find out if there's a more global way to set the parameter one time without having to create a trigger that sets the following session parameter:</p> <pre><code>ALTER SESSION SET NLS_DATE_FORMAT = 'MM/DD/YYYY'; </code></pre> <p>And here's the relevant part of my stored procedure:</p> <pre><code>CREATE OR REPLACE PROCEDURE DATE_DIM_PROCEDURE(P_DATE DATE) AUTHID CURRENT_USER --Not sure why this is needed since my only two users, but it throws an error without it IS V_START_DATE DATE := '01/01/1950'; V_CURRENT_DATE DATE := V_START_DATE; V_END_DATE DATE := '12/31/2099'; BEGIN EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_LANGUAGE = ''AMERICAN'' '; EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_TERRITORY = ''AMERICA'' '; EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_CALENDAR = ''GREGORIAN'' '; EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_DATE_FORMAT = ''MM/DD/YYYY'' '; EXECUTE IMMEDIATE 'CREATE TABLE (...)'; WHILE V_CURRENT_DATE &lt;= V_END_DATE NEW_DATE(P_DATE); --Procedure call that inserts values into table LOOP; END DATE_DIM_PROCEDURE; </code></pre> <p>Once the procedure runs (and calls the subsequent procedure to insert values), when I open the table, for any user, the <code>NLS_DATE_FORMAT</code> hasn't changed (i.e. it's still in the format <code>DD-MON-RR</code> instead of <code>MM/DD/YYYY</code>).</p> <p>Thanks.</p>

    1. COI edited my post, Alex...hopefully I answered all of your questions. Basically, I'm expecting that when any user looks at a table with dates in it, he/she will see them in the format `MM/DD/YYYY` (which I thought was possible).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
