MYSQL, Copy selected fields from one table to another

Question

In MySQL, How do I copy a FIELD with all RECORDS from TABLE1 to TABLE2 which corresponds to a primary key ie: EMPLOYEE no.?

Answer 1

Insert into Delivery (DeliveredDate, appid, DownloadSize, UploadSize) select Delivered, Appid, DownloadSize,UploadSize from Delivery_Summary;

Answer 2

The query for copy data from one table to another is:

Insert into table2 (field1, field2)  select field1, field2 from table1

If you want to copy only selected values, then use where clause in query

Insert into table2 (field1, field2)  select field1, field2 from table1 where field1=condition
