title: SQL incremental data
body: <p>i am trying to get only incremental records on one of the table SQL.</p>
  <p>Example Table1--need to insert data 10 times per day from some source data. Suppose I have inserted 10 records in the morning. Another new records came after one hour. SO total will be 20 records. And it keep going more and more through all day. And I need to run script to show only increment part. SO whatever I show in the morning should not include next run. Basically each time main table updated , i need to run script to show only updated new rows not old exiting rows.</p>
