update columns between two tables

update columns between two tables

update columns between two tables

(OP)


Hi
I have two tables with column A and column B. I want to update column B of table9 with column B of table1 .

table1
A | B
----|----
10 |12
14 |16

table9
A | B
----|----
1 |3
2 |4



I am trying this query in ms access from Vb.net. It pastes the column below the existing data


update table1 t1 LEFT JOIN table9 T9 on t1.a = t9.a SET t9.b = t1.b


table9
A | B
----|----
1 |3
2 |4
|12
|16

How do I write a update query that will replace the existing column like this?

table9
A | B
----|----
1 |12
2 |16

Thanks

RE: update columns between two tables

Based on your example:

table1
 A | B
---|----
10 |12
14 |16

table9
A | B
--|----
1 | 3
2 | 4
 
and your outcome:

table9 
A | B
--|----
1 |12
2 |16
 

What is you logic that
table1.A with 10 = table9.A with 1 ? 10 = 1?
table1.A with 14 = table9.A with 2 ? 14 = 2?

Have fun.
