记录MySQL中复制一行记录的简易操作（mysql复制一行）

With the rapid development of the Internet, more and more people use MySQL database and become familiar with basic database operations. For example, copying a row of records in MySQL is a common operation. Here is a brief outline of how to operate it.

First, login the MySQL database. We need to use the `SHOW DATABASES` command to view existing databases, select the database you want to use, and then use the `USE` command to switch databases. Once logged in, we can use the `SHOW TABLES` command to view the tables in the database, and then select the table to accomplish.

Second, use the INSERT INTO query to add a row of record data to the target table (suppose it is TA); this query syntax is as follows:

INSERT INTO TA SELECT * FROM TA WHERE condition;

In this query, TA is the target table, and the condition is used to select the required data records.

Third, use the UPDATE query to modify the row. This query syntax is as follows:

UPDATE TA SET origin_field = replace_value WHERE condition;

In this query, TA is the target table for the row to be modified, and the condition is used to select the required data record.

At last, use DELETE query to delete the original record. Its query syntax is as follows:

`DELETE FROM TA WHERE condition;`

This query is used to identify the record in the table to be deleted based on the condition.

In summary, we can follow the steps above to complete the operation of copying a row of record in MySQL database. This is a convenient way to save time and is suitable for small projects.
