Ambiguous sort column error <csp:search>

#CSP #SQL #InterSystems IRIS

A bit of an old school CSP question.  <csp:search> is a really nice, quick way to make easy lookups for CSP pages, especially for back office stuff that doesn't need to look pretty for the modern web app user.

At any rate, I'm here at the moment:

<csp:search SHOWSQL=1 NAME="OrgSearch" SELECT="OrganizationName Organization Name,Abbreviation,Software->Abbreviation Software" WHERE="OrganizationName Organization Name,Abbreviation,Software->Abbreviation Software" STARTVALUES=",,Software" PREDICATES="%startswith,%startswith,%startswith" CLASSNAME="AppLibrary.Organization" OPTIONS="popup" ONSELECT="OrgSearchSelect">

When I try to sort by the second column, the Organization Name column, I get an ambiguous search error.  With SHOWSQL=1 I can see that the alias I indicate in the SELECT param is not translated to the SQL query as SELECT Software->Abbreviation as Software so it won't see that as a different column name.  I can't use AppLibrary.Organization.Abbreviation or Organization.Abbreviation as they are invalid for this use (these options do work in the SQL explorer in the SMP though).

Any suggestions on how I can overcome this sort issue?

The problem can be solved in two ways:

  1. use OPTIONS="popup,sortbox"
  2. make a correction to the %CSP.PageLookup
    Write "&nbsp;<a href=""javascript:searchSort("_..QuoteJS(value)_");"" title=""Sort Results by "_alias_""">"
|
V
Write "&nbsp;<a href=""javascript:searchSort("_i_");"" title=""Sort Results by "_alias_""">"

In both case, the query will take the form "ORDER BY <the ordinal number of the field>", instead of "ORDER BY <field name>"

Thank you!

sortbox - If present, the Search Page displays a set of radio buttons that allows the user to choose how to sort the results.

I wouldn't have immediately thought that would solve it but it makes sense along with your explanation.

Out of curiosity, how would you override that write statement in %CSP.Lookup?  Isn't that generated code which one wouldn't want to touch?
