Enable WordPress Permalink In Localhost Using XAMPP?

Do you want to change wordpress permalink in localhost using XAMPP but return page not found? So this is the right place for you to fix it and using permalink in localhost. As default, XAMPP was disabled rewrite module for .htaccess so it will ignore any rewrite module that needed to make permalink. To enable this module you just need easy one single step!
Here we go … By default, XAMPP will have folder installation in C:\xampp. Now open C:\xampp\apache\conf\httpd.conf using your favourite text editor (i prefer to Notepad++ since they very powerfull than original notepad) and find this code. If you using Notepad++ like me just press Ctrl+G and enter 118 to go to lines 118.

(#LoadModule rewrite_module modules/mod_rewrite.so)

Remove mark (#) from begining code. Now your code should be like this

(LoadModule rewrite_module modules/mod_rewrite.so)

Save file and close. Your permalink now is ready to use. Anyway to setting permalink in wordpress go to Dashboard > Settings > Permalinks. Usually i use only “/%postname%/” setting to more friendly in search engine. Of course it would be effective if you do this for online site.

What are the difference between DDL, DML and DCL commands?

DDL

Data Definition Language (DDL) statements are used to define the database structure or schema. Some examples:

• CREATE - to create objects in the database
• ALTER - alters the structure of the database
• DROP - delete objects from the database
• TRUNCATE - remove all records from a table, including all spaces allocated for the records are removed
• COMMENT - add comments to the data dictionary
• RENAME - rename an object

DML

Data Manipulation Language (DML) statements are used for managing data within schema objects. Some examples:

• SELECT - retrieve data from the a database
• INSERT - insert data into a table
• UPDATE - updates existing data within a table
• DELETE - deletes all records from a table, the space for the records remain
• MERGE - UPSERT operation (insert or update)
• CALL - call a PL/SQL or Java subprogram
• EXPLAIN PLAN - explain access path to data
• LOCK TABLE - control concurrency

DCL

Data Control Language (DCL) statements. Some examples:

• GRANT - gives user's access privileges to database
• REVOKE - withdraw access privileges given with the GRANT command

TCL

Transaction Control (TCL) statements are used to manage the changes made by DML statements. It allows statements to be grouped together into logical transactions.

• COMMIT - save work done
• SAVEPOINT - identify a point in a transaction to which you can later roll back
• ROLLBACK - restore database to original since the last COMMIT
• SET TRANSACTION - Change transaction options like isolation level and what rollback segment to use
