Harminize sql state thrown when closing a connection with pending transaction
between net end embedded drivers
--------------------------------------------------------------------------------------------------------------
Key: DERBY-3114
URL: https://issues.apache.org/jira/browse/DERBY-3114
Project: Derby
Issue Type: Improvement
Affects Versions: 10.3.1.4
Reporter: Dag H. Wanvik
Priority: Minor
* Embedded (thrown from EmbedConnection#close):
State: 25000 (LANG_INVALID_TRANSACTION_STATE)
Text in English locale: "Invalid transaction state."
* Network client (thrown from Connection#checkForTransactionInProgress)
State: 25001 (CANNOT_CLOSE_ACTIVE_CONNECTION)
Text in English locale: "Cannot close a connection while a transaction is
still active."
I don't see why these should differ between the drivers. The network client
error message is more explanatory, I think.
The standard says about disconnect statement, section 17.3, general
rule 6: If any SQL-connection in L is active, then an exception
condition is raised: invalid transaction state - active SQL-transaction.
According to section 23.1 SQLSTATE (p.1075):
Subcondition: Active SQL transaction
subclass: 001
so, in this case, so it would appear that the use of 25001 is correct,
not 25000. I suggest we change embedded to use 25001 also, and release
note it, since it has application impact.
