Hi . I'm having trouble with the AUTO INCREMENT statement in SQL. I've built the table : CREATE TABLE tenants( apartment_number_first_floor INT AUTO_INCREMENT, family_name VARCHAR (12) DEFAULT NULL, sur_name VARCHAR (8) DEFAULT NULL, telephone_number INT(3) NOT NULL, PRIMARY KEY (apartment_number_first_floor) ); when inserting a row: INSERT INTO tenants VALUES(' ',' '); The IDE doesn't accept the column count: ER_WRONG_VALUE_COUNT_ON_ROW: Column count doesn't match value count at row 1 So i tried filling the rows just to check if the IDE will run the statement INSERT INTO tenants VALUES(103,'שקלובין','מרתה',203); but the IDE refuses to increment Any ideas? Thanks

I have a table where a column stores the output of a uniqid-meaning a random number that every time the function is called, it is different. I have set this to be the primary key of the table. Do I need to set it AUTO INCREMENT also? Or do you think maybe is better to create a separate column named primary and set this to auto increment?

I am working on a blog for a friend's website. Upon testing the database which holds her blog posts (for security issues and whatnot), and dropping random rows from it, I have noticed that the id field does not re-organize itself. The way I will be displaying her posts (5 per page, with previous and next buttons) depends on the id being in order and with no gaps. Is there any way I can put in a script using PHP or MySQL to organize these in case of a row being removed once the blog goes live? Also, I have noticed that I can put in one entry, drop it, and then when I test another one the id starts back at 2. The only way to get it to start at 1 again that I have seen is going into PHPmyAdmin and emptying the table. Thanks,Mark
