I get the following error: 2:57:08,074 INFO STDOUT : Data truncation: Incorrect date value: '2' for column 'FROMDATE' at row 1 12:57:08,074 INFO STDOUT at .checkErrorPacket(MysqlIO. The fields in the data base are Date object. If I execute the program after October 26 (after daylight savings ends) the bug will not be visible (by sheer bad luck, of me being the same TZ as UTC). The object Date is initializing with Object Long. When reading it, I got the day before because it came out in my TZ (which happens to be one hour behind).
I'm in Portugal, currently with daylight savings and I wrote today's date to the database in UTC TZ, which correctly appear in the DB. 3.1: I nitialize a string with the SQL query as follows. It involves a series of steps give below with declaration and syntax for interpretation.

I pulled this source code out of a real-world Java application, so Ill break it into small steps, and hopefully it will make sense. Step 3: Retrieve Contents of a Table Using JDBC connection: Suppose cuslogin table has columns namely id,name,email and the user wants to see the contents of cuslogin table. The prepareStatement () method accepts various parameters. result.next () String tableName result.getString (3) To read meta data about columns of a particular table, call the getColumns () method DatabaseMetaData interface like this: 1. The following code reads name of the first table: 1.

Second, you construct a SQL UPDATE statement and create PreparedStatement object by calling the prepareStatement () method of the Connection object. The getTables () method returns a ResultSet object in which the 3 rd column stores the name of the table.

To summarize, the implementation of ResultSet.getdate(int, Calendar) is not respecting the ResultSet API description, because it eventually leaves out the timezone information, causing the reading of the DATE field from the database to be done in the default timezone (has coded in TimeUtil.fastDateCreate() when Calendar is null). Heres a JDBC Timestamp example, showing how to read a Java Timestamp field from a database Timestamp column (a MySQL Timestamp field) in a SQL SELECT statement. First, you open a connection to MySQL database by reusing the utility class named MySQLJDBCUtil that we developed in the previous tutorial. getString on Date-Field in Database creates exception. I've looked into the code and posted another comment on bug #23584, which I believe can be related with this problem. Sérgio Fernandes I've started with the same symptom: a date written in a DATE column came back a day before when read.
