showresultset Function

Syntax

V showResultSet(P rs )

Arguments

rs

Pointer

Description

Quick preview of records in an AlphaDAO resultset. (Shows a max of 100 records).

Example 

The showResultSetFunction() is a useful utility function to quickly show data in an AlphaDAO resultset. It is typically used in the Interactive window, or while debugging code. Here is an example of an Interactive window session:

dim cn as sql::Connection
cn.open("::Name::sqlserver2012_northwind")
dim sql as c = "select * from customers where city = 'london'"
cn.PortableSQLEnabled = .t.
?cn.Execute(sql)
= .T.

dim rs as sql::ResultSet
rs = cn.ResultSet
showResultSet(rs)

After you have called the showResultSet() function once to show a resultset, you cannot call it a second time to show the same resultset without first executing the query again. That's because AlphaDAO resultsets are 'forward only'.
