Question:
Using JDBC, how can I turn a database table into a series of SQL INSERT statements that can recreate the table?
Answer:
Dumping a database table into a set of insert statements is just amatter of selecting all of its rows and constructing insert statementsbased on their column values.
You can determine the number of columnsin a table by accessing the ResultSetMetaData for a ResultSet withgetMetaData() and then calling ResultSetMetaData.getColumnCount().Getting the values of each row is just a matter of calling getString()with the column number as an argument. The following programdemonstrates the approach:
import java.sql.*;/*** * This program accepts a table name, a JDBC driver name, and a database * connection URL as arguments. The program connections to the database * and reads all the rows in the table, printing SQL INSERT statements * on standard output representing the data. ***/public final class dump { public static String DUMP_QUERY = "SELECT * FROM "; public static final void main(String[] args) { Connection connection; Statement statement; ResultSet result; ResultSetMetaData metaData; String table, driver, url; StringBuffer buffer = new StringBuffer(8192); int columns; if(args.length < 3) { System.err.println("Usage: dump
