How to know the version of the embedded HSQLDB?

You can determine the version of the embedded HSQLDB engine with the following Basic macro [oobas] Option Explicit

Sub hsqlVersion

Dim databaseURLOrRegisteredName As String
databaseURLOrRegisteredName = "hsqldb"
 ' adjust this string to your needs. It needs to be the name of a registered database,
 ' or a complete URL
Dim databaseContext As Object
databaseContext = createUnoService( "com.sun.star.sdb.DatabaseContext" )
Dim databaseDocument As Object
databaseDocument = databaseContext.getByName( databaseURLOrRegisteredName )
Dim connection As Object
connection = databaseDocument.getConnection( "", "" )
MsgBox "product version: " & connection.getMetaData().getDatabaseProductVersion()

End Sub Note that this will give you a version number such as "1.8.0", but not "". To my best knowledge, this last digit in the HSQLDB version cannot be obtained by any means at runtime.
