It is possible to write the INSERT INTO statement in two forms.

The first form doesn't specify the column names where the data will be inserted, only their values:

INSERT INTO table_name
VALUES (value1, value2, value3,...)

The second form specifies both the column names and the values to be inserted:

INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)
*/

INSERT INTO STUDENT
VALUES(10, 'AMITAB', '12-JAN-1968')

/*
UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value
*/
UPDATE STUDENT
SET STUDENT_ID=1
Where STUDENT_ID=10

/*

The DELETE statement is used to delete rows in a table.
SQL DELETE Syntax

Vinita

Excellent plugin, anamizg idea, greatMy only problem is that i am showing different ads for different categories. For example:if this post is category a'show ad a'if this post is category b'show ad b'And i can't think how to maintain that while integrating this plugin. I either need a way to do:if this post is category c'ad_buttons(c)or justad_buttons()And have it automatically detect the category based on settings. But the first option would be awesome enough. I guess basically i just need multiple instances of the ad_button, as was mentioned previously in the comments but for another purpose.Keep up the great work, really awesome.Cheers!!
