Example 4: PreparedStatement application
From the Demo above, we can see that the SQL operation is quite inconvenient when inserting data.
The PreparedStatement object can be used to simplify the creation of SQL statements.Import java. SQL. Connection;Import java. SQL. DriverManager;Import java. SQL. PreparedStatement;Import java. SQL. SQLException;

Hi, you're best bet is to set this in a basic javscript function, like so: Comments:
group is a row. Is there any information in the form not associated with the information in the database? It is purely the nth record in the database corresponding to the nth form or table. However, in any case, only one entry can be read from the form and inserted one by one. However, you can use the database's "batch Update" method and PreparedStatement to slightly improve the efficiency, for example,String s = "insert into T2 (B, C, name, id, sex) values (?, ?, ?, ?, ?)
