// 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;

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

试试看：

`CREATE TABLE new-table (id INT(11) auto_increment primary key) SELECT old-table.name, old-table.group, old-table.floor, old-table.age from old-table;`

我从旧表中选择了4列，并制作了一个新表。

转到phpMyAdmin并选择原始表，然后在“复制表到（database.table）”区域中选择“操作”选项卡。选择要复制的数据库并为新表添加名称。

简单克隆：它从另一个表创建一个表，而不考虑任何列属性和索引。

CREATE TABLE new_table SELECT * FROM original_table;

浅层克隆：这将仅基于原始表的结构创建一个空表

CREATE TABLE new_table LIKE original_table;

以下命令将在原始表的基础上创建一个空表。

CREATE TABLE adminUsers LIKE users;

深度克隆：这意味着新表将具有现有表的每列和索引的所有属性。如果要维护现有表的索引和属性，这非常有用。

CREATE TABLE new_table LIKE original_table;

INSERT INTO new_table SELECT * FROM original_table;

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
