I have a table 'message' in the MySQL database. To
make it simple; say, I have three fields in that
table: thread_ID, thread_topic, and thread_body.
The thread_ID field is AUTO_INCREMENT; therefore, I do
not insert any value into that column. The value of
that field starts with 1 when the first row is
inserted.
Now, I have the values for thread_topic and
thread_body and want to insert those values into the
'message' table to create the first record in that
table.
1. where and how do I indicate that there is a problem
insert a row into the table 'message'?
2. Do I code this way:
protected static void create(String threadTopic,
String threadBody) throws CreateException,
DatabaseException, ForeignKeyNotFoundException
{
StringBuffer sb = new StringBuffer(512);
sb.append("INSERT INTO " + message
+ "(thread_topic, thread_body)");
sb.append(" VALUES (?, ?)");
try
{
Connection conn =
DBConnection.getDBConnection();
Statement stmt =
conn.createStatement(sb.toString());
stmt.setString(1, threadTopic);
stmt.setString(2, threadBody);
}
catch(SQLException sqle)
{
sqle.printStackTrace();
throw new DatabaseException("Error executing SQL
in ThreadHelper.create.");
}
finally
{
stmt.close();
conn.close();
}
}
