If I have Table1 as
A B C
1 b.1 c.1
2 b.2 c.2
1 b.3 c.3
My second table Table2 as
A D E
1 d.1 e.1
2 d.2 e.2
I need to insert into an empty Table3 the values from above such that it looks like this.
A B C D E
1 b.1 c.1 d.1 e.1
2 b.2 c.2 d.2 e.2
1 b.3 c.3 d.1 e.1
So basically I need to insert each row of Table1 into Table3. For each row I need to check for column A and find the corresponding value D and E from the column and insert into Table3. Is it possible to do this in one single query?
To copy Table1 to Table3 I can use the query
INSERT INTO Table3(A,B,C) SELECT A,B,C FROM Table1
And then I need to take each row from Table3 and using A update the values of D and E from Table2. Is there a better solution that I can use to insert directly from both tables to Table3? Any help is appreciated, as I am a beginner with database and queries.
