Question

I have a table (result of a stored procedure from someone else), and it retuns a table ##tableT in the form

1      2    3    4    5     6
----------------------------------------------
467    116  480  477  491   697
NULL   19   481  113  488   466
123    4354 477  466  55    480
NULL   NULL NULL 527  83    629
45     34   NULL  5   483   483

As you can see it has NULLS, and most important the name of the columns are numbers, so when I do

SELECT coalesce(1, -1) as att1, coalesce(2, -1) as att2,....,coalesce(6, -1) as att6 FROM [dbm].[dbo].[##tableT];

I get:

1   2   3   4   5   6
1   2   3   4   5   6
1   2   3   4   5   6
1   2   3   4   5   6
1   2   3   4   5   6

Instead of:

1      2    3    4    5     6
----------------------------------------------
467    116  480  477  491   697
-1     19   481  113  488   466
123    4354 477  466  55    480
-1     -1   -1   527  83    629
45     34   -1   5   483    483

Answer 1

try

SELECT ISNULL([1], -1) as att1, ISNULL([2], -1) as att2,....,ISNULL([6], -1) as att6 FROM [dbm].[dbo].[##tableT];
