title: Is Numeric in Oracle
body: <p>I'm working in oracle 11g. I've a table with <code>Number</code> as the datatype. For development purpose we have created a staging table with <code>varchar</code> type. Initially data would be loaded in the staging table. We need find out the records that has only number in that column, since the data might contain the noises. Is there any way to find it.</p>
