Hi,
I have a table which uses two columns to represent its primary key, a transaction id and then the sequence number.
I tried what was recommended http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-mapping in section 2.2.3.2.2, but when I used the Hibernate session to commit this Entity object, it leaves out the TXN_ID field in the insert statement and only includes the BA_SEQ field!
What's going wrong? Here's the related code excerpt:
@Id
@Column(name="TXN_ID")
private long txn_id; public long getTxnId(){return txn_id;} public void setTxnId(long t){this.txn_id=t;}
@Id
@Column(name="BA_SEQ")
private int seq; public int getSeq(){return seq;} public void setSeq(int s){this.seq=s;}
And here are some log statements to show what exactly happens to fail:
In createKeepTxnId of DAO base class: about to commit Transaction :: txn_id->90625
seq->0 ...<Snip>...
Hibernate: insert into TBL (BA_ACCT_TXN_ID, BA_AUTH_SRVC_TXN_ID, BILL_SRVC_ID,
BA_BILL_SRVC_TXN_ID, BA_CAUSE_TXN_ID, BA_CHANNEL, CUSTOMER_ID, BA_MERCHANT_FREETEXT,
MERCHANT_ID, MERCHANT_PARENT_ID, MERCHANT_ROOT_ID, BA_MERCHANT_TXN_ID, BA_PRICE,
BA_PRICE_CRNCY, BA_PROP_REQS, BA_PROP_VALS, BA_REFERENCE, RESERVED_1, RESERVED_2,
RESERVED_3, SRVC_PROD_ID, BA_STATUS, BA_TAX_NAME, BA_TAX_RATE, BA_TIMESTAMP, BA_SEQ)
values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
[WARN] util.JDBCExceptionReporter SQL Error: 1400, SQLState: 23000
[ERROR] util.JDBCExceptionReporter ORA-01400: cannot insert NULL into
("SCHEMA"."TBL"."TXN_ID")
The important thing to note is I print out the entity object which has a txn_id set, and then the following insert into statement does not include TXN_ID in the listing and thus the NOT NULL table constraint rejects the query.
