I'm coming back here as I again need your help! Which of the following is the better choice? The question is: I have a table <code>myTable</code> with <code>['DateYYYYMMDD','field1', 'field2', 'field3', 'MyField']</code> and every day someone inserts many records. I have to create 2 (fast) views <code>myView1</code> and <code>myView2</code> that select records (from <code>myTable</code>) created in the last 30 days, and with different <code>MYFIELD</code> values. I have found some distinct simple solutions and I would like to know which is the fastest: Solution1 <pre><code>--myView1: select field1, field2, ...., fieldn, MYFIELD from myTable where DateYYYYMMDD > sysdate -30 and MYFIELD in ('65643L', '65643L174', '65643L8N', ... '6564L7174', '6564L78N','6564L78N_2O15', ... '6564L78N3226T2_2O15', '6564L78N8N322', '6564L78N6T2', '6564L78N6T2_2O15', '6564L7-NOTT1-6T2', '6564L76T2', ... '6563XP8N322', '6563XP8N322_2O15', '6563XP8N3226T2', '6563XP8N3226T2_2O15', '6563XP8N6T2', '6563XP-NOTT1-6T2', '6563XP6T2', '9563XPT1', '9563XPT1_2O15', ... '9566UB', '9566UB_2O15', '9566UB174', '9566UB8N', '6566UB8N_2O15', '6566UB8N174', '6566UB8N322', ...) myView2: select field1, field2, ...., fieldn, MYFIELD from myTable where DateYYYYMMDD > sysdate -30 and MYFIELD in ('9P26_B', '9P26_BN', '9P26_8N', ... '9P26_8NN', '9P26_2O158N9', '556_B', '556_8N', ... '5566NP4P', '696N65T', '696N65T6T2', ... '696W1P_B', '696W1P_8N') </code></pre> --solution 2 <pre><code>--myView1: select field1, field2, ...., fieldn, MYFIELD from myTable where DateYYYYMMDD > sysdate -30 and (MYFIELD like '656%' or MYFIELD like '956%') --myView2: select field1, field2, ...., fieldn, MYFIELD from myTable where DateYYYYMMDD > sysdate -30 and (MYFIELD like '9P26%' or MYFIELD like '556_%' or MYFIELD like '5566%' or MYFIELD like '696%') </code></pre> --solution 3 <pre><code>--myView1: select field1, field2, ...., fieldn, MYFIELD from myTable where DateYYYYMMDD > sysdate -30 and (REGEXP_LIKE(MYFIELD, '^656') or REGEXP_LIKE(MYFIELD, '^956')) --myView2: select field1, field2, ...., fieldn, MYFIELD from myTable where DateYYYYMMDD > sysdate -30 and (REGEXP_LIKE(MYFIELD, '^9P26') or REGEXP_LIKE(MYFIELD, '^556_') or REGEXP_LIKE(MYFIELD, '^5566') or REGEXP_LIKE(MYFIELD, '^696')) </code></pre> I hope that explains what I need, if there is a better solution, please suggest it! Thank You Very Very Much!

Guidance

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.
