Also look at the %SQL way of running queries which has some advantages, there are a few ways of doing it, one of which is:
s stmnt=##class(%SQL.Statement).%New()
s sc=stmnt.%PrepareClassQuery("GMECC.DocmanConnect.Tables.vwNewGPs","GetRows")
s rs=stmnt.%Execute()
w rs.%SQLCODE,!
while rs.%Next() {
// s var=rs.%Get("ColumnName") - for known column names
s var1=rs.%GetData(columnNumber)
w var,!
w var1
}
