Using setDate in PreparedStatement

Question

In order to make our code more standard  we were asked to change all the places where we hardcoded our SQL variables to prepared statements and bind the variables instead    I am however facing a problem with the setDate      Here is the code           DateFormat dateFormatYMD   new SimpleDateFormat  yyyy MM dd HH mm ss            DateFormat dateFormatMDY   new SimpleDateFormat  MM dd yyyy HH mm ss            Date now   new Date            String vDateYMD   dateFormatYMD format now           String vDateMDY   dateFormatMDY format now           String vDateMDYSQL    vDateMDY           java sql Date date   new java sql Date 0000-00-00       requestSQL    INSERT INTO CREDIT REQ TITLE ORDER  REQUEST ID                        ORDER DT  FOLLOWUP DT        values                             prs   conn prepareStatement requestSQL                    prs setInt 1 new Integer requestID                     prs setDate 2 date valueOf vDateMDYSQL                    prs setDate 3 date valueOf sqlFollowupDT      I get this error when the SQL gets executed       java lang IllegalArgumentException     at java sql Date valueOf Date java 138      at com cmsi eValuate TAF TAFModuleMain CallTAF TAFModuleMain java 1211    Should I use setString   instead with a to date

The docs explicitly says that java sql Date will throw         IllegalArgumentException - if the date given is not in the JDBC date escape format  yyyy- m m- d d       Also you shouldn t need to convert a date to a String then to a sql date  this seems superfluous  and bug-prone    Instead you could   java sql Date sqlDate    new java sql Date now getTime     prs setDate 2  sqlDate   prs setDate 3  sqlDate

If you want to add the current date into the database  I would avoid calculating the date in Java to begin with  Determining  now  on the Java  client  side leads to possible inconsistencies in the database if the client side is mis-configured  has the wrong time  wrong timezone  etc  Instead  the date can be set on the server side in a manner such as the following   requestSQL    INSERT INTO CREDIT REQ TITLE ORDER                         REQUEST ID  ORDER DT  FOLLOWUP DT                       VALUES    SYSDATE  SYSDATE   30          prs setInt 1  new Integer requestID      This way  only one bind parameter is required and the dates are calculated on the server side will be consistent   Even better would be to add an insert trigger to CREDIT REQ TITLE ORDER and have the trigger insert the dates  That can help enforce consistency between different client apps  for example  someone trying to do a fix via sqlplus

Not sure  but what I think you re looking for is to create a java util Date from a String  then convert that java util Date to a java sql Date   try this   private static java sql Date getCurrentDate String date         java util Date today      java sql Date rv   null      try            SimpleDateFormat format   new SimpleDateFormat  dd-MM-yyyy            today   format parse date           rv   new java sql Date today getTime             System out println rv getTime            catch  Exception e            System out println  Exception      e getMessage           finally           return rv                 Will return a java sql Date object for setDate     The function above will print out a long value   1375934400000

The problem you re having is that you re passing incompatible formats from a formatted java util Date to construct an instance of java sql Date  which don t behave in the same way when using valueOf   since they use different formats   I also can see that you re aiming to persist hours and minutes  and I think that you d better change the data type to java sql Timestamp  which supports hours and minutes  along with changing your database field to DATETIME or similar  depending on your database vendor    Anyways  if you want to change from java util Date to java sql Date  I suggest to use  java util Date date   Calendar getInstance   getTime    java sql Date sqlDate   new java sql Date date getTime             more code here prs setDate sqlDate
