Database error: Table ‘cart.cscart_stat_search_robots’ doesn’t exist (1146)

What is wrong!
Please help
I have seen lots of guys complaining about same problem. Please developer do something 
I have also faced same thing. I have tried to look into upgrade script and change_structure.sql, I have seen that upgrade script deletes all tables in db, and then while restoring database it creates new tables and alter any table structure if necessary.
But in change_structure.sql file where alter stat_search_robots query is return,
ALTER TABLE cscart_stat_search_robots CONVERT TO CHARACTER SET utf8;
ALTER TABLE cscart_stat_search_robots
CHANGE robot_id robot_id mediumint(8) unsigned NOT NULL auto_increment first, COMMENT=‘’, DEFAULT CHARSET=‘utf8’;
```
but till this stage there is no table created in db with this name, and script is trying to attempt alter structure of that table. so I guess this problem raised.
After this error if we look in database there are few tables missing, like stored_session. So i have imported these tables from fresh 2.0.5 database but still it’s not working.
I am clueless. Please anyone can assist in this.
HI,
I did a minor change in change_structure.sql file and it worked. As I have mentioned in my last msg that it seems upgrade script is not creating cscart_stat_search_robots table itself. So I have added table create query before alter cscart_stat_search_robots query in change_structure.sql file
Add this
[QUOTE]CREATE TABLE IF NOT EXISTS cscart_stat_search_robots (
robot_id mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
id varchar(64) NOT NULL DEFAULT ‘’,
name varchar(128) NOT NULL DEFAULT ‘’,
cover_url varchar(255) NOT NULL DEFAULT ‘’,
details_url varchar(255) NOT NULL DEFAULT ‘’,
owner_name varchar(128) NOT NULL DEFAULT ‘’,

) ENGINE=MyISAM DEFAULT CHARSET=‘utf8’;
[/QUOTE]
Before
[QUOTE]ALTER TABLE cscart_stat_search_robots CONVERT TO CHARACTER SET utf8;
ALTER TABLE cscart_stat_search_robots
CHANGE robot_id robot_id mediumint(8) unsigned NOT NULL auto_increment first, COMMENT=‘’, DEFAULT CHARSET=‘utf8’;
[/QUOTE]
(I am attaching my modified change_structure.sql with this message too)
After this change upgrade script worked smoothly, and it passed all upgrade stages successfully (below urls changed in address bar while upgrade)
/upgrade135sp4-204.php?step=rebuild_data
/upgrade135sp4-204.php?step=rebuild_others
I got “The database upgrade is finished successfully!” message at end. I was excited that things worked but when I accessed frontend it is giving error
[QUOTE]Database error: Unknown column ‘user_type’ in ‘where clause’ (1054)
Invalid query: DELETE FROM cscart_user_session_products WHERE user_type = ‘U’ AND timestamp < 1244814909[/QUOTE]
Now what to do???
Hureeeeeeee… Puzzle solved,
CS2.0.5 is upgraded successfully from 1.3.5 SP4,
In continuation to my previous message. As per error user_type field was missing in cscart_user_session_products table. So I have simply run alter query to add this field in table.
Alter Query
[QUOTE]ALTER TABLE cscart_user_session_products
ADD COLUMN user_type char(1) NOT NULL default ‘R’;[/QUOTE]
- Login to phpmyadmin, select cs 2.0.5 database
- Run above given query, and all set.
- Login to cs2.0.5 admin panel, all data seems to be imported (I need to check if everything is imported properly, it was 693 MB database)
Now checking store, if any error occurs.
Thanks dude!
This worked!! 
Although none of my images have been restored!
Any one know how to fix this eror? Trying to Upgrade to version 2.0.8
