Find Expressions removed

In 9.0, the Gosu language no longer supports find expressions. Gosu retains equivalent functionality for retrieving information from the application database with the query builder APIs. Configuration upgrade tools for Version 9.0 convert legacy find expressions to equivalent query builder code.

For example, the find expression in the following example Gosu code from earlier versions of PolicyCenter returns Address instances that are located in the city of Chicago.

// Query the database for addresses in Chicago.
var findQuery = find (a in Address where (a.City == "Chicago"))

 // Print the addresses in the query result.
for (a in findQuery) {
  print (a.AddressLine1 + " / " + a.City + ", " + a.PostalCode)
}

After upgrade, the preceding find expression is converted to the following query builder code, which also returns addresses that are located in the city of Chicago.

uses gw.api.database.Query

 // Query the database for addresses in Chicago.
var findQuery = Query.make(Address).compare("City", Equals, "Chicago").select()

 // Print the addresses in the query result.
for (a in findQuery) {
  print (a.AddressLine1 + " / " + a.City + ", " + a.PostalCode)
}
