mysql-java-connector: ResultSet getObject failure on Timestamp column if null
I had strange situation working with ResultSet when fetching Timestamp column from MyTable.
The cause of the failure was due to null value in timestamp_column !
The solution suggested about (zeroDateTimeBehavior=convertToNull) in the article, helped me overcome the failure.
All you need to do is:
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
Class.forname("com.mysql.jdbc.Driver");
Connection connection = DriverManager.getConnection(
"jdbc:mysql://host:port/database",
"username", "password");
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery("SELECT timestamp_column FROM mytable");
while(rs.next()) {
rs.getObject("timestamp_column");
}
The cause of the failure was due to null value in timestamp_column !

"jdbc:mysql://host:port/database?zeroDateTimeBehavior=convertToNull",
"username", "password");
