将数据从一个表转移到另一表

Question

Can anybody help me to create a good way to transfer data from one table to another table?

For example:

table1

ID | Name

1  | Juan
2  | Two

table2

(no content)

What I want is a loop that will transfer the data of table1 to table2 . While not all data of table1 is transferred to table2 the loop continues.

Answer 1

The standard SQL approach is:

insert into table2(id, name)
    select id, name
    from table1;

You don't need a loop.

Answer 2

I suppose you mean to do this in VB. Let conn, rs1 and rs2 already initialized, you can obtain your goal as shown:

rs1.Open "Table1", conn
rs2.Open "Table2", conn, 3, 3
Do Until rs1.EOF
  rs2.AddNew()
  rs2("id") = rs1("id").Value
  rs2("name") = rs1("name").Value
  rs2.Update
  rs1.MoveNext()
Loop
rs2.Close()
rs1.Close()

Answer 3

Try this in sql

Insert Into table2(id, name)
Select id, name
From table1
Where <Conditions to insert>

OR

Select * into <target_Table> 
From table1
Where <Conditions to insert>

The difference between both the query is ,in first one you need to create table before execute.In second one it will automatically create the table.
