It sounds so bleepin' simple but...
Following my previous quesionts... and thanks for the help so far. All I want to do right now is get a specific row from my postgres database into a variable so that I can work with it.
I'm not well-versed in java/groovy, and I don't have enough experience with Bonita YET.
I've tried scripts and queries, I've tuned and modified, but it comes down to I need a script, and in my case since the row may or may not exist in postgres, I have created a dummy row that signals that the customer does not exist:
import groovy.sql.Sql;
import java.sql.Driver;
def list=[];
Sql sql=BonitaSql.newInstance("jdbc:postgresql://172.17.0.2:5432/HFDataProd","bonita_db_user","bpm", new org.postgresql.Driver())
sql.eachRow("SELECT * FROM customer WHERE customer = \'" + enteredname +"\';") {
list += it.customerid.toInteger();
list += it.customer.toString();
list += it.password_open.toString();
list += it.password_encrypted.toString();
list += it.buyfor1.toString() == "null" ? ("0").toInteger() : it.buyfor1.toInteger();
list += it.buyfor2.toString() == "null" ? ("0").toInteger() : it.buyfor2.toInteger();
list += it.buyfor3.toString() == "null" ? ("0").toInteger() : it.buyfor3.toInteger();
list += it.buyfor4.toString() == "null" ? ("0").toInteger() : it.buyfor4.toInteger();
list += it.buyfor5.toString() == "null" ? ("0").toInteger() : it.buyfor5.toInteger();
list += it.lastchanged_date.toString();
list += it.created_date.toString();
}
if (list.size()==0) {
list += ("0").toInteger()
list += "none"
list += "none"
list += "none"
list += ("0").toInteger()
list += ("0").toInteger()
list += ("0").toInteger()
list += ("0").toInteger()
list += ("0").toInteger()
list += "none"
list += "none"
}
return list;
Now that being said, I can read the database, but I can't change the result type so I can't assign it.
Doesn't do me much good yet.
Thanks.

And since I can't change the return type from java.lang.Sring, I don't seem to be able to get past here.
Reflecting... if I could do it in an SQL statement, this problem would go away. So far, I've not seen a working WHERE clause, or at least I've not been able to mimic a working scenario.
I really, really wish that there were 'real-world' application examples - fooling around with a vacation management example is great, and it teaches a lot, but real-world applications use database, and external connection, and all sorts of good things.
Thanks for listening to my rant.
I am an outsider like you, but this group is pretty solid. When I am ready to buy, it will be bonitasoft.

I guess I'm having a problem communication...
If I run the connector with the script "select * from customer where customerid =2;" I get the result I'd like - the connector allows me to assign it to an nxn result.
That's what I want. Then I can use it.
Except, I don't always want to get customerid 2! I'd like to be able to use a variable or something!!!! How do I write that???
Thanks!
Apologies for the sparky.
Apologies for the snarky.
