update table with the same items

Question

See more:

I have two tables A and B shown.
Table A
HoleNo Depth_from Depth_to
A1 1 2
A1 3 4
A1 5 6

Table B
HoleNo Depth_from Depth_to
A1
A1
A1

Now How do I update table B so that it looks like table A
Note that no changes must be made to table A.
I have tried to assign id's to table B so that I do the update based on the unique id's, but since I am not to make any changes to table A I am finding it very difficult.

this is my code

SQL

I first save all HoleNo into B from A
sqlSTR = "SELECT * FROM A"
ExecuteSQLQuery(sqlSTR) 'call function to execute the query
For Each row1 As DataRow In sqlDT.Rows

sqlSTR = "INSERT INTO B (HoleNo) VALUES ('" & row1(0) & "')"
ExecuteSQLQuerylocal(sqlSTR) 'call function to execute the query

Next

So after inserting all HoleNo then I try to update the rest of the fields with this code

sqlSTR = "SELECT * FROM A"
ExecuteSQLQuery(sqlSTR) 'call function to execute the query
For Each row1 As DataRow In sqlDT.Rows

sqlSTR = "UPDATE B SET Depth_from ='" & row(0) & "' WHERE HoleNo ='" & row(0) & "'"
ExecuteSQLQuerylocal(sqlSTR)

I first save all HoleNo into B from A
sqlSTR = "SELECT * FROM A"
ExecuteSQLQuery(sqlSTR) 'call function to execute the query
For Each row1 As DataRow In sqlDT.Rows

sqlSTR = "INSERT INTO (B) VALUES ('" & row1(0) & "')"
ExecuteSQLQuerylocal(sqlSTR) 'call function to execute the query

Next

then I update table B using this
sqlSTR = "SELECT * FROM A"
ExecuteSQLQuery(sqlSTR) 'call function to execute the query
For Each row1 As DataRow In sqlDT.Rows

sqlSTR = "UPDATE B SET Depth_from='" & row1("Depth_from") & "' WHERE HOLE_NUMBER='" & row(0) & "'"
ExecuteSQLQuerylocal(sqlSTR) 'call function to execute the query

Solution 1

Delete Table B from Database
then Create Table B from Table A

Use Sql Query

SQL

     DROP TABLE B
GO
     SELECT * INTO B From A
GO
