一个向数据库发出create table SQL的JDBC语句示例。

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)
);

TableCreate.java

package com.mkyong.jdbc.statement.table;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class TableCreate {

    private static final String SQL_CREATE = "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)"
            + ")";

    public static void main(String[] args) {

		// auto close 
        try (Connection conn = DriverManager.getConnection(
                "jdbc:postgresql://127.0.0.1:5432/test", "postgres", "password");
             Statement statement = conn.createStatement()) {

            // if DDL failed, it will raise an SQLException
            statement.execute(SQL_CREATE);

        } catch (SQLException e) {
            System.err.format("SQL State: %s\n%s", e.getSQLState(), e.getMessage());
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}

输出量

A table 'employee' is created.

PS已通过PostgreSQL 11和Java 8测试

pom.xml

<dependency>
		<groupId>org.postgresql</groupId>
		<artifactId>postgresql</artifactId>
		<version>42.2.5</version>
