Clear Table Data in PL/SQL: 3 Methods

There are multiple ways to clear table data in PL/SQL, three commonly used methods are listed below:

1. You can use the DELETE statement to remove all data from a table, here is an example code:

BEGIN
   DELETE FROM 表名;
END;

1. The TRUNCATE TABLE statement can quickly delete all data from a table, but it will also reset any auto-increment columns if they exist. Here is an example code:

BEGIN
   TRUNCATE TABLE 表名;
END;

1. To completely clear table data and recreate the table structure, you can use the DROP TABLE statement to delete the table and then recreate it. Here is an example code:

BEGIN
   DROP TABLE 表名;
   CREATE TABLE 表名 (...);
END;

The above are three commonly used methods to clear table data, the specific method chosen depends on the specific situation and requirements. When using these methods, please be cautious and make sure to back up any data that needs to be retained.
