Expected behavior
return correct primary key
Actual behavior
return first db column
Reason analyze (If you can)
ShardingSphereConnection#prepareStatement(java.lang.String, java.lang.String[]) is not working
Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
postgresql db:
create table if not exists t_aa (
user_id VARCHAR(50) not null,
id serial primary key,
address_id BIGINT not null,
status VARCHAR(50));Example codes for reproduce this issue (such as a github link).
public static void test(DataSource dataSource) throws SQLException {
final Statement statement = dataSource.getConnection().createStatement();
statement.execute("create table if not exists t_aa (\n" +
" user_id VARCHAR(50) not null, \n" +
" id serial primary key, \n" +
" address_id BIGINT not null, \n" +
" status VARCHAR(50));");
final PreparedStatement preparedStatement = dataSource.getConnection().prepareStatement("INSERT INTO t_aa (user_id, address_id, status) " +
"VALUES (?,?,?);"
, new String[]{"id"});
preparedStatement.setString(1, "a");
preparedStatement.setLong(2, 2);
preparedStatement.setString(3, "c");
preparedStatement.execute();
final ResultSet generatedKeys = preparedStatement.getGeneratedKeys();
while (generatedKeys != null && generatedKeys.next()) {
Object userId = generatedKeys.getObject(1);
System.out.println("resultset userId:"+userId);
}
}
