Question

I’m not sure if I’m writing the following SQL statement correctly? (Using T-SQL)

I have two tables:

Table 1: [dbo].[t_Orgnzs]

[id] = INT
[nm] = NVARCHAR(256)

Table 2: [dbo].[t_Usrs]

[id] = INT
[ds] = NVARCHAR(256)
[oid] = INT (referenced [dbo].[t_Orgnzs].[id])

I need to select elements from Table 2, ordered by the [oid] column ascending from 1 to 16, but the catch is that the [oid] references a string in the Table 1, that I actually need to return as a result.

So for say, if tables were laid out like so:
Table 1:

id   nm
1    Name 1
2    Name 2
3    Name 3
4    Name 4

And Table 2:

id   ds      oid
1    A       2
2    B       4
3    C       1

The resulting query must return:

3 C Name 1
1 A Name 2
2 B Name 4

So here’s the SQL I’m using:

WITH ctx AS (
  SELECT [id],
         [ds],
         (SELECT [nm] FROM [dbo].[t_Orgnzs] WHERE [id]=[dbo].[t_Usrs].[oid]) AS organizName,
         ROW_NUMBER() OVER (ORDER BY organizName ASC) AS rowNum 
  FROM [dbo].[t_Usrs]
            )
             SELECT [id], [ds], organizName 
             FROM ctx 
             WHERE rowNum>=1 AND rowNum<=16;

And I’m getting an error: “Invalid column name ‘organizName’.”

Answer 1

How about this one

select id, ds, nm
from
(
    select ROW_NUMBER() OVER (ORDER BY o.nm ASC) AS rowNum, u.id, u.ds, o.nm
    from t_Usrs u inner join t_Orgnzs o on (u.oid = o.id)
) t
 WHERE rowNum>=1 AND rowNum<=16;
