Getting a data table reference from NewSQLQuery() << Run Background with Names Default to Here(1);

I'm having trouble getting the data table reference if I run in the background.  Anyone know how to get around this?  

 

names default to here(1);

sql_query = New SQL Query(
 Connection(
  "ODBC:DSN=Test Source;DATABASE=Test;"
 ),
 QueryName( "Thingy" ),
 Select(
  blah
 ),
 From(
  other blah
 )
);

sql_query << Run Background(
 OnRunComplete(
  dt = queryResult;
  dt = data table(queryResult<<GET name=""></GET>

Re: Getting a data table reference from NewSQLQuery() << Run Background with Names Default to Here(1);

One option is to use a new namespace for the subquery:

names default to here(1);

// Namespace to share data between background query and this script
ns = new namespace( "subquery" );

// The background query will set to 1 when the background query is complete
ns:isdone = 0;

sql_query = New SQL Query(
 Connection( "ODBC:DSN=Test Source;DATABASE=Test;" ),
 QueryName( "Thingy" ),
 Select( blah ),
 From( other blah )
);

sql_query << Run Background(
 OnRunComplete(
  ns = namespace( "subquery" );
  ns:result = queryResult;
  ns:dt = data table ( queryResult << Get Name );
  ns:isdone = 1;
 )
);

//every second check if the query is done (timeout after 10 seconds)
i=0;
while( ( i < 10 ) & ( ns:isdone == 0 ) ,
 i++;
 if( ns:isdone == 1, show( ns:dt ), show( "Query not done yet." ); wait( 1 ); );
);

//now you can reference the data table
show( ns:dt );

Re: Getting a data table reference from NewSQLQuery() << Run Background with Names Default to Here(1);Any news on this. I'm running into the very same problem!Re: Solving Common Data Table Problems With JMP® 13: Can We Replace Summary and Join With the New JMP Query Builder?

I put in a bug to support.  It looks to me like <

query_complete = 0;
dt_list = {};
dt_array = associative array();
str = "A";
ns = new namespace("Test");
query << Run Background(
 OnRunComplete(
  try(show(query_complete)); //this won't show, but if you run it twice it will show as 1
  try(show(dt_list));
  try(show(dt_array));
  try(show(str));
  try(show(ns));
  try(show(namespace("Test")));
  
  query_complete = 1;
 )
);

In my test I did not add the Names Default To Here(1) - it looks like that is the difference.  The OnRunComplete() function is not running in the same Here namespace as the original script.  If you create your own namespace to hold the results, you should be able to access the variables after the query completes.

Even if I do this. 

 

query_complete = 0;
query << Run Background(
 OnRunComplete(
  query_complete = 1;
  dt = queryResult;
  show(dt); //shows correctly for either one
 )
);

It seems like On Run Complete doesn't affect me.  If I run it it in parts then check the value of query_complete, it's still 0  even after the Run complete script is run.

Adding the wait(1) does not make the second show(dt) work.  That's the problem.  There is no way I can find to get a data table reference from a sql query run in the background.

Maybe I'm not understanding, but I think this shows why you need the <

 

If you add a Wait(1) between the <
