Question

All,

I have the following query and it creates a result set as I expect, but the real records all comeback with a row number of 1. I was expecting them to come back with an incrementing row number like the fake records do (when you see the code and results you’ll see what I mean.).

Declare @FakeEquipment TABLE(
EquipmentID varchar(25),
EquipmentDesc varchar(150), 
TrackingID varchar(25))

As you can see the records from the fake equipment table all have the correct row number whereas the real records all have a row number of 1.

What I’m trying to do is split the record set between 2 SSRS 2005 matrix controls so each one has 6 records (for a max of 12) But I’m unable to do that. Any help in this direction is appreciated.

Answer 1

This is numbering the records as expected. You are partitioning the data by Equipment_EquipmentID and the data that you are getting from the first part of the union the values are all different. So the row_number will not increment.

The row_number() will only increment if the values in the partition are the same which your values are not.

If you want to use row_number() you might have to alter the way you are partitioning.

For example using the following data:

CREATE TABLE yourData
    ([Equipment_EquipmentID] varchar(6), [JobAccount_TrackingID] varchar(10))
;

INSERT INTO yourData
    ([Equipment_EquipmentID], [JobAccount_TrackingID])
VALUES
    ('1218', '0441-01409'),
    ('127', '0441-01409'),
    ('1350', '0441-01409'),
    ('1354', '0441-01409'),
    ('1445', '0441-01409'),
    ('16-003', '0441-01409'),
    ('30', '0441-01409'),
    ('3-007', '0441-01409'),
    ('6-002', '0441-01409'),
    ('6-006', '0441-01409')
;

If you using the following query:

select *,
  row_number() over(partition by Equipment_EquipmentID order by JobAccount_TrackingID) rn1
from yourdata;

You will see that the row number is not incrementing.

But if you change the partition to the following:

select *,
  row_number() over(partition by JobAccount_TrackingID order by JobAccount_TrackingID) rn2
from yourdata;

The row number increments.

See SQL Fiddle with Demo of both queries.
