Notmally when you read SQL data using RDBMS interface to PI you get one value by one column, it means one column by tag, for instance:
Select A,B,C where fecha=#12-05-09#
Where TagA = A, TagB=B and TagC=C
Our need is to read in this way:
Select values where fecha=#12-05-09#
Where values = "A,B,C"
So we have all the values in one field like comma separate string
How can we read these ?
