Hello,
I have a problem with the following statement:
SELECT * FROM (SELECT ? FROM DUAL)
it gives this error with H2 1.4.191:
org.h2.jdbc.JdbcSQLException: Unknown data type: """?1"""; SQL statement:
SELECT * FROM (SELECT ? FROM DUAL) [50004-192]
at org.h2.message.DbException.getJdbcSQLException(DbException.java:345)
at org.h2.message.DbException.get(DbException.java:179)
at org.h2.message.DbException.get(DbException.java:155)
at org.h2.table.Table.setColumns(Table.java:425)
at org.h2.table.TableView.initColumnsAndTables(TableView.java:220)
at org.h2.table.TableView.init(TableView.java:98)
at org.h2.table.TableView.<init>(TableView.java:65)
at org.h2.table.TableView.createTempView(TableView.java:535)
at org.h2.command.Parser.readTableFilter(Parser.java:1168)
Code to reproduce:
PreparedStatement st = cnx.prepareStatement("SELECT * FROM (SELECT ? FROM
DUAL)");
st.setTimestamp(1, new Timestamp(System.currentTimeMillis()));
rs = st.executeQuery();
rs.next();
System.out.println(rs.getObject(1));
rs.close();
st.close();
"SELECT ? FROM DUAL" works fine.
The problems is that the type of the parameter cannot be known when the
statement is prepared so I'm not sure how the parser should deal with that.
Boris.
