Hi- I have a Dought.

I have 2 tables, they are:

Table 1 with 2 fields and Table 2 that has 3 fields.

Table 1 has this 2 fields:

Name and address.

Table 2 has this 3 fields:

Number , Name and address.

This table 1 has 20000 records (for example) and I need to put this records (insert ) into table 2.

Two of the fields in this two tables are exactly of the same type and name.
But table 2 has one more field (that is not an identity, and it will not became one identity field) , that is numeric (int).

Table 2 has already same records and I need to insert now , all the data from table 1 to table 2.

Suppose my table 2 data is this:

1 Paul Street1
2 Marc Street2

How can I insert (code sample) the data of table1 into table 2 and the field of type number of table 2 is incremented in 1 every time a new record is placed on table2 ?

I only know how to do this by using cursors, but that’s not good.

Can someone help me please?

In this case , the first record to be insert into table2 would be inserted with the number 3.

Tks,

Pedro

INSERT INTO Table2 (Number, Name, Address)
SELECT ROW_NUMBER() OVER(ORDER BY Name, Address) AS counter,
    Name, Address
FROM Table1

This will insert based on the result set, which will start from 1.

I'm sorry, I didn't see you needed to start from 3.

INSERT INTO Table2 (Number, Name, Address)
SELECT ROW_NUMBER() OVER(ORDER BY Name, Address) + 2 AS counter,
    Name, Address
FROM Table1

Sorry also for not putting my name in the reply.
I have such a few time to dedicate to SSC that sometimes I tend to be too concise.

Regards
Gianluca

tks once again for help.

But in this case i think you did not understud my question , i don't need to always start from 3.
I need to start from the last number in table 2 , in this case is 3, but it could be 10.

tks, again,

Pedro

Ok, so I guess you need something like this:

INSERT INTO Table2 (Number, Name, Address)
SELECT ROW_NUMBER() OVER(ORDER BY Name, Address) + (SELECT MAX(Number) FROM Table2) AS counter,
    Name, Address
FROM Table1
