INSERT INTO Table 1 ( Field 1, Field 2, Field 3 )
SELECT Table 2.Field 1, Table 2.Field 2, Table 2.Field 3
FROM Table 2
WHERE Table2.Field3>20
This example implements appending the values of Field1, Field2, and Field3 in Table 2 that satisfy the conditions to the corresponding fields in Table 1, which requires that the corresponding fields have the same data type and not necessarily the same name
