> [Sql] withBatch fails when batchSize == number of addBatch call
> ---------------------------------------------------------------
>
> Key: GROOVY-8288
> URL: https://issues.apache.org/jira/browse/GROOVY-8288
> Project: Groovy
> Issue Type: Bug
> Components: SQL processing
> Affects Versions: 2.5.0-beta-1, 2.4.12
> Reporter: Antoine Kapps
>
> {{Sql.withBatch(batchSize, ..)}} calls {{delegate.executeBatch()}} both when batchCount reaches batchSize, and at the end of the method (after the call to the "batch statement" closure).
> Thus, if the number of {{addBatch()}} calls in the closure is exactly the same as, or a multiple of {{batchSize}}, one too much call to {{executeBatch()}} is made : nothing has been added to the batch.
> Which, at least with HSQLDB 2.4.0, leads to a SQLException on that very last call.
> Test to reproduce (compliant with SqlBatchTest)
> {code:java}
> void testWithBatchSizeHavingSizeSameSizeAsStatements() {
> def numRows = sql.rows("SELECT * FROM PERSON").size()
> assert numRows == 3
> def myOthers = ['f4':'l4','f5':'l5','f6':'l6','f7':'l7']
> def result = sql.withBatch(myOthers.size(), "insert into PERSON (id, firstname, lastname) values (?, ?, ?)") { ps ->
> myOthers.eachWithIndex { k, v, index ->
> def id = index + numRows + 1
> ps.addBatch(id, k, v)
> }
> }
> assert result == [1] * myOthers.size()
> assert sql.rows("SELECT * FROM PERSON").size() == numRows + myOthers.size()
> // end result the same as if no batching was in place but logging should show:
> // FINE: Successfully executed batch with 4 command(s)
> }
> {code}
