Yea, a quick search of my classpath shows about 5 different libraries doing
an interrupt at one point or another, and I'm not even sure yet which one
was biting me.
I'm not trying to use H2, I'm just trying to use the MVStore directly. The
MVStore jar package doesn't contain the classes
Thank you for the answer.
I am looking at the source code H2 more specific Function.java
and I see that a couple of functions are initially set with Value.NULL
(since at that time the return data type is not known)
Although there is a method called optimize
that is used that for some
Hello.
This function in H2 does not have exact return type, it may return
TIMESTAMP, TIMESTAMP WITH TIME ZONE, DATE, or TIME depending on type of the
second argument. That's why its return type is not defined. You can add an
explicit cast.
SELECT CAST(DATE_TRUNC('MONTH', column) AS TIMESTAMP)
Hi,
I am using H2 version "1.4.197"
While trying to get the column type with ResultSetMetaData getColumnType()
of a query like:
SELECT date_trunc('MONTH', "Date_Column")
I get the value 0 (Null as defined in JDBC Types)

Yes... One case, that was biting us, is using
java.util.concurrent.ExecutorService.shutdownNow(). This was calling
Thread.interrupt() in our case. It was relatively easy to resolve: now we
use shutdown() instead. See

Hi,
Try this: "retry:nio:" + ... See also TestConcurrent.testInterruptReopen()
(It would be good to improve documentation for this I guess).
