The MySQL ALTER command is very useful when you want to change a name of your table, any table field or if you want to add or delete an existing column in a table.

Let us begin with the creation of a table called testalter_tbl.


Dropping, Adding or Repositioning a Column

If you want to drop an existing column i from the above MySQL table, then you will use the DROP clause along with the ALTER command as shown below −

A DROP clause will not work if the column is the only one left in the table.

To add a column, use ADD and specify the column definition. The following statement restores the i column to the testalter_tbl −

After issuing this statement, testalter will contain the same two columns that it had when you first created the table, but will not have the same structure. This is because there are new columns that are added to the end of the table by default. So even though i originally was the first column in mytbl, now it is the last one.

To indicate that you want a column at a specific position within the table, either use FIRST to make it the first column or AFTER col_name to indicate that the new column should be placed after the col_name.

Try the following ALTER TABLE statements, using SHOW COLUMNS after each one to see what effect each one has − Mysql system timezone.

The FIRST and AFTER specifiers work only with the ADD clause. This means that if you want to reposition an existing column within a table, you first must DROP it and then ADD it at the new position.

Altering (Changing) a Column Definition or a Name

To change a column's definition, use MODIFY or CHANGE clause along with the ALTER command.

For example, to change column c from CHAR(1) to CHAR(10), you can use the following command −

With CHANGE, the syntax is a bit different. After the CHANGE keyword, you name the column you want to change, then specify the new definition, which includes the new name.

Try out the following example −

If you now use CHANGE to convert j from BIGINT back to INT without changing the column name, the statement will be as shown below −

The Effect of ALTER TABLE on Null and Default Value Attributes − When you MODIFY or CHANGE a column, you can also specify whether or not the column can contain NULL values and what its default value is. In fact, if you don't do this, MySQL automatically assigns values for these attributes.

The following code block is an example, where the NOT NULL column will have the value as 100 by default.

If you don't use the above command, then MySQL will fill up NULL values in all the columns.

Altering (Changing) a Column's Default Value

You can change a default value for any column by using the ALTER command.

Try out the following example.

You can remove the default constraint from any column by using DROP clause along with the ALTER command.

Altering (Changing) a Table Type

You can use a table type by using the TYPE clause along with the ALTER command. Try out the following example to change the testalter_tbl to MYISAM table type.

To find out the current type of a table, use the SHOW TABLE STATUS statement.

Renaming (Altering) a Table

To rename a table, use the RENAME option of the ALTER TABLE statement.

Try out the following example to rename testalter_tbl to alter_tbl.

You can use the ALTER command to create and drop the INDEX command on a MySQL file. We will discuss in detail about this command in the next chapter.

Xampp Command Prompt

Or XLMPP for that matter 😉

There are two ways to do it. Both are basically the same, but one just makes it a lot easier. We’ll go over the harder one first.

First Method:

Start the command prompt, and cd to the xampp directory. It’ll usually be something like:
cd ././Program Files/xampp
if you used the installer and default install location.

Cmd Xampp Mysql

Once in there, cd to the mysql bin directory.
cd mysql/bin

Now, run the command:
mysql.exe --user=root --password=
And the MySQL command line will start. If you’ve changed the username or password of the MySQL user, you need to change the –user= and –password= accordingly.

Second method:

Mysql Console Xampp

Basically the same way as before, but we’ll create a batch file to make it easier.

First, create a file called mysql_command.bat in the XAMPP directory.

Edit this file with Notepad or any text editor, and paste in this:

Save it, and change the –user= and –password= if you’ve changed the user or password.

Xampp Install Command Line

Now, run mysql_command.bat and a command prompt will show up with the MySQL command line running.

It’s as easy as that.
