Knut Anders Hatlen commented on DERBY-4921:
-------------------------------------------
I believe this is the expected behaviour. There is no column called 'id' in the
table because Derby stores unquoted identifiers in upper case. The column name
is therefore 'ID'. To get the example code to work, you can either change the
CREATE TABLE statement to quote the column name, like this:
static String createTableSql = "CREATE TABLE tbl (\"id\" integer primary
key generated always as identity, name varchar(200))";
Or you can change the column name argument to executeUpdate() to upper case,
like this:
static String[] idColName = { "ID" };
Hope this helps.
