值得一提的是，检查表之前是否已存在尝试复制它：

CREATE TABLE IF NOT EXISTS new_table LIKE old_table;

INSERT new_table
SELECT * FROM old_table;

正如前面的回答所说，这将复制结构、数据和表的所有从属对象。

请参见MySql教程：

扩展此答案时，可以使用存储过程：

CALL duplicate_table('tableName');

这将导致名为tableName_20181022235959的重复表如果在

SELECT NOW();

结果：

2018-10-22 23:59:59

实施

DELIMITER $$
CREATE PROCEDURE duplicate_table(IN tableName VARCHAR(255))
  BEGIN
    DECLARE schemaName VARCHAR(255) DEFAULT SCHEMA();
    DECLARE today VARCHAR(14) DEFAULT REPLACE(REPLACE(REPLACE(NOW(), '-', ''), ' ', ''), ':', ''); -- update @ year 10000
    DECLARE backupTableName VARCHAR(255) DEFAULT CONCAT(tableName, '_', today);

    IF fn_table_exists(schemaName, tableName)
      THEN
        CALL statement(CONCAT('CREATE TABLE IF NOT EXISTS ', backupTableName,' LIKE ', tableName));
        CALL statement(CONCAT('INSERT INTO ', backupTableName,' SELECT * FROM ', tableName));
        CALL statement(CONCAT('CHECKSUM TABLE ', backupTableName,', ', tableName));
      ELSE
        SELECT CONCAT('ERROR: Table "', tableName, '" does not exist in the schema "', schemaName, '".') AS ErrorMessage;
      END IF;
  END $$
DELIMITER ;

DELIMITER $$
CREATE FUNCTION fn_table_exists(schemaName VARCHAR(255), tableName VARCHAR(255))
  RETURNS TINYINT(1)
  BEGIN
    DECLARE totalTablesCount INT DEFAULT (
      SELECT COUNT(*)
      FROM information_schema.TABLES
      WHERE (TABLE_SCHEMA COLLATE utf8_general_ci = schemaName COLLATE utf8_general_ci)
        AND (TABLE_NAME COLLATE utf8_general_ci = tableName COLLATE utf8_general_ci)
    );
    RETURN IF(
      totalTablesCount > 0,
      TRUE,
      FALSE
    );
  END $$
DELIMITER ;

DELIMITER $$
CREATE PROCEDURE statement(IN dynamic_statement TEXT)
  BEGIN
      SET @dynamic_statement := dynamic_statement;
      PREPARE prepared_statement FROM @dynamic_statement;
      EXECUTE prepared_statement;
      DEALLOCATE PREPARE prepared_statement;
  END $$
DELIMITER ;

除了上面的解决方案之外，您可以使用AS将其集成到一条线上。

CREATE TABLE tbl_new AS SELECT * FROM tbl_old;

要创建表结构，请仅使用以下代码：

CREATE TABLE new_table LIKE current_table; 

要将数据从表复制到另一个表，请使用以下代码：

INSERT INTO new_table SELECT * FROM current_table;

要使用索引和触发器进行复制，请执行以下两个查询：

CREATE TABLE new_table LIKE old_table; 
INSERT INTO new_table SELECT * FROM old_table;

要仅复制结构和数据，请使用以下方法：

CREATE TABLE new_table AS SELECT * FROM old_table;

我以前问过这个问题：

复制包含索引的MySQL表

// To copy specific column data use this one:
CREATE TABLE ut_axis_existrec LIKE ut_karvy_annexure; // To create new table

INSERT INTO ut_axis_existrec
(funding_ac,micr_no, warrant_no,
amount,invname,mfundcode,funding_dt,status,remarks1,amc_remark,created_at) 
SELECT  
t1.funding_ac,
t1.micr_no,
t1.warrant_no,
t1.amount,
t1.invname,
t1.mfund_code,
t1.funding_dt,
t1.status,
t1.remarks1,
t1.created_at
from ut_axis_karvy
inner join 
ut_axis_karvy_master as t2
on t1.micr_no = t2.micr_no;
