Hi,

Can somebody please help me to solve a problem, I am new to sql .

I have a table in which one column (Place) has some values like bellville, century city, constentia and ceres. Now in second table there are two columns property and value. Property column has values like population.rural.men.bellville.total, population.rural.men.constentia.total etc. Now I need to update the values of second table and iterate the first table to get the places. So in short like as follows

FOR [column(index) in table_1]

Begin

update table_2 set value = 'someValue' where key ='population.rural.men.'+column(index)+'.total'

END

What will be the sql for this?

Thanks

Manish

Where do you get the 'someValue' that you want to set the value column to? If that data is in a table, then you can do a set-based to query to do the update.

sounds like this to me

update t2 
set value = 'someValue' 
from table_2 t2
join table_1 t1
on property ='population.rural.men.'+ LTRIM(RTRIM(t1.Place)) +'.total'

As James suggested you could specify columnname instead of hardcoding if values reside in table column
