How to Handle MySQL's 0000-00-00 00:00:00 DATETIME Values in JDBC?

Managing DATETIME Values of 0000-00-00 00:00:00 in JDBC

MySQL's DATETIME data type allows storing "quasi-null" values represented by 0000-00-00 00:00:00. Retrieving such values using JDBC can be problematic, potentially resulting in exceptions or unexpected results.

Alternative Solution without Casting

One approach to handling these values is to modify the JDBC URL, adding the following parameter:

?zeroDateTimeBehavior=convertToNull

This instructs the driver to convert DATETIME values of 0000-00-00 00:00:00 to NULL instead of throwing an exception.

The MySQL manual provides additional insights into this issue:

• All-zero DATETIME values cannot be reliably represented in Java.
• Connector/J 3.1 throws an exception when encountering such values by default.

• The zeroDateTimeBehavior property allows customizing this behavior:

  • exception (default): Throws an SQLException.
  • convertToNull: Returns NULL instead of the date.
  • round: Rounds the date to 0001-01-01.
