Hey guys, i have a question.

i have an sql query

select DISTINCT UPPER(r_name) as r_name, UPPER(address) as address, area, location, p_code, tel, website, '<b>'+ r_name + '</b>' + '<br>' + address + '<br>' + area + '<br>' + location + '<br> Contact: ' + tel  as InfoWindowText, Latitude as Lat, Longitude as Lng FROM dbo.pretoria where active='Yes'


my problem is here

'<b>'+ r_name + '</b>' + '<br>' + address + '<br>' + area + '<br>' + location + '<br> Contact: ' + tel  as InfoWindowText

if my location is null it not pulling

so how can i have an if statement in that query so if loction is null it must not add the location and if it is not null add the loction to the nfoWindowText?

Hi
You can use ISNULL() function to check whether the location field is null or not. SQL query is pasted below:
select 
		DISTINCT UPPER(r_name) as r_name, 
		UPPER(address) as address, 
		area, 
		location, 
		p_code, 
		tel, 
		website, 
		'<b>'+ r_name + '</b>' + '<br>' + [address] + '<br>' + area + '<br>' + ISNULL(location,'') + '<br> Contact: ' + tel as InfoWindowText,
		Latitude as Lat, 
		Longitude as Lng
	FROM dbo.pretoria 
		 where active='Yes'
