2579943 - Set commands executed with java.sql.PreparedStatement may not remain in effect - SAP SDK for ASE


  • In jConnect, set commands do not remain in effect if they are executed by using java.sql.PreparedStatement and DYNAMIC_PREPARE connection property is true.
  • For example, you execute "set transaction isolation level 0" by using PreparedStatement and then execute a SELECT query.
  • The SELECT query should return a result set without being blocked because it's a dirty read, but in fact it can be blocked by another process holding an exclusive lock.
  • This is more likely to occur after you upgrade your jConnect to 7.0 ESD#3 or later.
