How to echo the SQL command in JDBC?

Question

When we use a PreparedStatement and execute query, is there a way to get the exact SQL command
sent to the server without any '?' marks? That would be an aid in debugging. Or is such a facility server-pecific? I am using MySQL with JDBC.
Thank you.

Answer 1

Why I want to see the SQL command now is that I am getting a nagging SQLException in the following
code. Would someone tell me why this code fails?
//Database connection successful.
//conn and pstmt are successfully created.
//variables 'pid' and 'subfolder' are already evaluated, and confirmed that they have valid values
int sub_id = 0;
String myquery = null;
ResultSet rs1 = null;
try{
myquery = "SELECT j15c_directory_id FROM j15t_directory WHERE (j15c_parent_id = ? AND j15c_name = ?)";
pstmt = conn.prepareStatement(myquery);
pstmt.setInt(1,pid);
pstmt.setString(2,subfolder);
rs1 = pstmt.executeQuery();
rs1.next();
sub_id =rs1.getInt("j15c_directory_id");
catch(java.sql.SQLException e1){
System.err.println("SQLException: " + e1.getMessage());
The error message I'm getting is "Before start of result set ".
