ACCESS
Example:
Copy Code code as follows:
INSERT into the products (Pronumber,casnumber,cnname,price,enname,baozhuang,pinpai) Select Pronumber,casnumber,cnname, Price,enname,baozhuang,pinpai from product22
1. Remove data from one table into another table with SQL. This is useful for data conversion between different programs, and is fast and complete:
Insert INTO table1 (column1,column2,...) Select Column1,column2,... from table2
(where Table1 's fields correspond to table2, mainly data types, and the number of fields must be equal)
2. Use one SQL to retrieve the data from a table to update the corresponding values in another table:
Copy Code code as follows:
Update table1,table2 set table1.column1=table2.column1 where Table1.column2=table2.column2
Just like the last one, it has to correspond. You can also extend updates to the corresponding values between multiple tables.
3. Compare the values of a corresponding field in two tables:
Copy Code code as follows:
SELECT * FROM table1 where ID isn't in (select ID from table2)
