A JDBC PreparedStatement example to insert a row into the database.
RowInsert.java
package com.mkyong.jdbc.preparestatement.row;
import java.math.BigDecimal;
import java.sql.*;
import java.time.LocalDateTime;
public class RowInsert {
private static final String SQL_INSERT = "INSERT INTO EMPLOYEE (NAME, SALARY, CREATED_DATE) VALUES (?,?,?)";
public static void main(String[] args) {
try (Connection conn = DriverManager.getConnection(
"jdbc:postgresql://127.0.0.1:5432/test", "postgres", "password");
PreparedStatement preparedStatement = conn.prepareStatement(SQL_INSERT)) {
preparedStatement.setString(1, "mkyong");
preparedStatement.setBigDecimal(2, new BigDecimal(799.88));
preparedStatement.setTimestamp(3, Timestamp.valueOf(LocalDateTime.now()));
int row = preparedStatement.executeUpdate();
// rows affected
System.out.println(row); //1
} catch (SQLException e) {
System.err.format("SQL State: %s\n%s", e.getSQLState(), e.getMessage());
} catch (Exception e) {
e.printStackTrace();
}
}
}
Table definition.
CREATE TABLE EMPLOYEE
(
ID serial,
NAME varchar(100) NOT NULL,
SALARY numeric(15, 2) NOT NULL,
CREATED_DATE timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP
PRIMARY KEY (ID)
);
P.S Tested with PostgreSQL 11 and Java 8

will this work in a multithreaded environment ,having simultaneous inserts and if the timestamp column is indexed on the db table .
how can use select query inside insert in PreparpreparedStatement.
ex; if I have used select max(id) from table and pass in preaparestmt for increment of id. I know index is a solution for same. But we cane use select in same or not.

Hi! I’ve got a little problem with a query. I have to insert records in the User table. In the database postgres User table joins to JobProfile with the key userId. So when I add a new user, userId is addes in User table and JobProfile. How can I do join in java? I’ve never used it. Can you write the query please? This is my query: String string=”INSERT INTO “User” (“userId”,”name”,”surname”,”mail”,”password”,”status”) Values(?,?,?,?,?,?)”;
PreparedStatement ad=db.con.prepareStatement(string);
ad.setString(1,user.getUserId());
ad.setString(2,user.getName());
ad.setString(3, user.getSurname());
ad.setString(4, user.getEmail());
ad.setString(5, user.getPassword());
ad.setBoolean(6, user.getStatus());
ad.executeUpdate(); So when I add a new user with this query, the user is added in the User table but not also in the JobProfile. I want also userId is added in the JobProfile table. Thank u.
