Build Identifier:


Reproducible: Always

Steps to Reproduce:

1.using jetbrains datagrip, this error occurs after connection

I fixed the driver source code by inserting at line 1945 (it is a copy/paste of the already existing code at line 1579) :

	/* statement is null for virtual result sets such as the ones that hold generated keys */
	if (this.getStatement() == null) {
		return getObject(columnName, new HashMap<String, Class<?>>());

btw, is there a repository we can contribute to ?

Thanks for reporting the issue.

As you can see in the changeset I used a different solution which is more in line with all the others getXxxx(String ColumnName) methods.
It will call the getObject(int columnIndex) method which already has the logic for dealing with:
if (this.getStatement() == null) { ...
So no need to duplicate that logic and code.
