In case someone is looking for a simple answer that mirrors scraimer and Explorer‘s but is written in Java using JDBC (I know I was), here’s a quick and dirty one that got the job done for me: import java.sql. The use of a wildcard didnt work: #1008 – Can’t drop database ‘whatever_%’ database doesn’t exist Anyway i would like to do this the easier way coz i wont be able to support this code(other guys will and you know… ) txt with each name in a line… so im coding a quick php that will take a file and delete all the databases in it, later i will try the % answer(if it works, it takes the correct answer for sure its the easier way). Right now, i asked the guy that is generating the databases to give me a. I can use any kind of language or plug in for mysql… so we CAN do this in some ways. I will be doing this job quite some times so i was wondering what would be the best way to do this? So you have your Whatever_something, Whatever_232, Whatever_blabla, …. All databases that i need to drop have the same prefix “Whatever_”.Īfter the prefix, the names are random. If a permanent table exists with the same name as the temporary table, MySQL will not delete the permanent table.Im runing mySQL in a server where i need to drop tons of databases (after some testing with the server). Please note that the above statement will delete only the temporary table. The above statement deletes the Student_marks table from MySQL. To drop a temporary table, you use the following syntax. Total_marks DECIMAL(10,2) NOT NULL DEFAULT 0.00, Let us now check the DROP TABLE statement for the temporary table. DROP TABLE courses, enrolls 3) Dropping Temporary Table To delete multiple tables in a single statement, you use the following statement. Table: enrolls mysql> SELECT * FROM enrolls ![]() Table: courses mysql> SELECT * FROM courses Suppose, we have two tables named courses and enrolls as follows: In this example, we will check how to drop multiple tables using a single DROP TABLE statement. However, if we use the IF EXISTS keywords before mentioning the table_name in the DROP TABLE statement, MySQL does not issue any error. If we try to drop a table that does not exist then MySQL issue an error as below. The above statement removes the Products table permanently from the database. To drop this Products table, you use the following statement. Suppose we have a table named Products in the mysqltutorial database as below. In this example, we will check an example of dropping a single table from the MySQL database. Let us check the different options of the MySQL DROP TABLE command using a few examples. RESTRICT and CASCADE – These optional parameters are reserved for the future release of MySQL.In this case, MySQL will not issue any error, simply it will not drop any table if the table does not exist. So, it is better to use this optional parameter along with the DROP TABLE statement. ![]()
