C# PISDK - How do you pull a full column of data from a PISDK server using C#? -


i looking pull full column data table in pisdk server, , populate blank fields in column field column in same row. similar select statement in sql:

select nvl(column1, column2) table1

if not familiar sql, returns column2 if column1 null, otherwise return column1

my main problems can point server, cannot full column , not sure how replace null column1 fields column2.

i able answer own question. future reference, load in pi tags column in csv , copy each row correct column1 of other csv. find anywhere tag null , pull corresponding column2 value.
