2 questions for the following statement:
String sql = "SELECT H.invoice_no, H.invoice_date, H.customer_no,
I.part_no,I.qty,I.unit_price"
+ " FROM invoice H, invoice_item I "
+ " WHERE H.invoice_no = I.invoice_no"
+ " AND H.invoice_no =\" PMI02/000001"\";
^ ^
1 2
1: should there be a space here ?
2: why is the outer quote escaped ?
Shouldn't it be:
+ " AND H.invoice_no =\"PMI02/000001\"";

Emne: Need help in 1:N mapping
Hi all,
I am using OJB for 1:N mapping. The code and mapping is shown below.
When i run this query the following error occur.
The column actually should be invoice_no.
[org.apache.ojb.broker.accesslayer.JdbcAccess] ERROR: SQLException
during the execution of the SQL query: Invalid column name
'PMI02/000001'. Invalid column name 'PMI02/000001'.
String sql = "SELECT H.invoice_no, H.invoice_date, H.customer_no,
I.part_no,I.qty,I.unit_price"
+ " FROM invoice H, invoice_item I "
+ " WHERE H.invoice_no = I.invoice_no"
+ " AND H.invoice_no =\" PMI02/000001"\";
Query query = QueryFactory.newQuery(InvoiceBO.class, sql);
PersistenceBroker broker =
PersistenceBrokerFactory.createPersistenceBroker(
new PBKey("repositoryB.xml", null, null));
Collection result = broker.getCollectionByQuery(query);
Can anyone help or point out where i get wrong??
Thanks in advance.
