I declare statement
strSel = "J.number >'"+ pStartNo +"' and J.number <='" + pEndNo + "'"

run the command
SELECT NUMBER FROM INVTABLE WHERE &strSel

When I put the pStartNo = "SHA/AI/004/03/2007", pEndNo="SHA/AI/013/03/2007"

It gives us the result contain "SHA/AI/010/04/2006" . Why ?
it seems the above number should not between the rang ???
