Subject Groovy variables inside an SQL "loop"
Date Mon, 10 Oct 2005 14:09:11 GMT
I was wondering if anyone could help with
a seemingly trivial problem:

When I have this code:

pageFilter = '*';
linker = '*';
myParamValue = request.getParameter(myParam);
if ( myParamValue == "true" ) {
 pageFilter  = pageFilter + linker;
 linker = '';
}

it work just fine, but I soon as I wrap this in an
SQL "loop":

sql.eachRow(pageSQL ) { rows | 
  if ( myParamValue == "true" ) {
   pageFilter  = pageFilter + linker;
   linker = '';
  }
}

It fails - both on the  "pageFilter  = pageFilter "
and the " linker = '';" step (tested both independantly)
part - for example, having:

sql.eachRow(pageSQL ) { rows | 
  if ( myParamValue == "true" ) {
   foo  = pageFilter + linker;
   bar = '';
  }
}

works just fine as well- but is not what I want to 
accomplish - why does Groovy not permit variables
to reference/change themselves inside the SQL, and 
how does one then accomplish this?

Thanks
Derek
