Count the Number of No's in a Row

I can probably do this in a long winded way somehow but can't help thinking there may be an easier approach.

I need to count the number of times the word 'No' appears in each row of a table.

For example...

UserID	OptIn1	OptIn2	OptIn3	OptIn4	OptIn5	Count of No's
1	No		No	No		3
2		No			No	2
3	No	No		No	No	4
4						0
5			No			1

There are actually around 100 of these OptIn fields that can either be blank or have a 'No' in them so i need to count the total number of No's for each row across around 100 fields.

My current thinking is to concatenate the fields together and do a SubStringCount on the word No

Any ideas appreciated

t1:

LOAD * INLINE [

UserID,OptIn1,OptIn2,OptIn3,OptIn4,OptIn5

1,No,,No,No,

2,,No,,,No

3,No,No,,No,No

4,,,,,

5,,,No,,

];

t2:

CrossTable(Data,Value,1)

Load

UserID,OptIn1,OptIn2,OptIn3,OptIn4,OptIn5

Resident t1

;

Left Join(t1)

Load

UserID,

Count(Data) as [Count of No's]

Resident t2

where Value='No'

Group By UserID

;

drop table t2;

Hi Try this:

Do a cross table:

sum(if(WildMatch(Data,'No'),1,0)) ! !

Thanks that works nicely.

My SubStringCount effort below seems to work a bit faster as your t2 table gets very large with my data volumes but your solution looks more elegant.

SubStringCount(BR_Ad_Promo_Opt_In & BR_Awards_Opt_In & BR_Brand_Opt_In & BR_Circ_Opt_In & BR_Conferences_Opt_In & BR_Exhibitions_Opt_In & BR_Forums_Opt_In &
