Error in SQL Syntax (MYSQL 5.0) - mysql

Does anybody know what is wrong in this MYSQL 5.0 syntax?
CREATE TABLE IF NOT EXISTS target (
_id int(11) NOT NULL AUTO_INCREMENT,
time timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
map_id int(11) DEFAULT NULL,
left int(11) DEFAULT NULL,
top int(11) DEFAULT NULL,
status tinyint(1) NOT NULL,
temperature int(11) DEFAULT NULL,
humidity float DEFAULT NULL,
lum int(11) DEFAULT NULL,
PRIMARY KEY (_id),
FOREIGN KEY (map_id) REFERENCES map(id) ON DELETE CASCADE
)
I'll show you the error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'left INTEGER DEFAULT NULL,
top INTEGER DEFAULT NULL,
status tinyint(1) NOT' at line 5

Because left is a MySQL 5.0 reserved word. Also, even though you can escape the field name, it's never a great idea to use reserved words in a table definition.

you must write it like this:
CREATE TABLE IF NOT EXISTS target (
_id int(11) NOT NULL AUTO_INCREMENT,
time timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
map_id int(11) DEFAULT NULL,
`left` int(11) DEFAULT NULL,
top int(11) DEFAULT NULL,
status tinyint(1) NOT NULL,
temperature int(11) DEFAULT NULL,
humidity float DEFAULT NULL,
lum int(11) DEFAULT NULL,
PRIMARY KEY (_id),
FOREIGN KEY (map_id) REFERENCES map(id) ON DELETE CASCADE
)
look at the `` (backticks) characters in left row !

You're using reserved words as field names. You can do that, but then you have to properly escape them, like this:
CREATE TABLE IF NOT EXISTS target (
`_id` int(11) NOT NULL AUTO_INCREMENT,
`time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`map_id` int(11) DEFAULT NULL,
`left` int(11) DEFAULT NULL,
`top` int(11) DEFAULT NULL,
`status` tinyint(1) NOT NULL,
`temperature` int(11) DEFAULT NULL,
`humidity` decimal(13,2) DEFAULT NULL,
`lum` int(11) DEFAULT NULL,
PRIMARY KEY (_id),
FOREIGN KEY (map_id) REFERENCES map(id) ON DELETE CASCADE
)
My advise would be to avoid reserved names.

Unknown column 'xxx' in 'field list'

As sometimes happens, a block of code fails and no matter how hard you try, you can't figure out where it is. In these cases a second pair of eyes sometimes sees what the brain doesn't register. I think this is one of those cases. It's almost certainly my fault and I did something wrong but I honestly can't figure out where.
This is a SELECT I wrote
SELECT
`a.dev_act_id`,
`a.dev_act_code`,
`a.dev_act_desc`,
`a.dev_act_type`,
`a.lang_code`,

WHERE
`pa.dev_plan_id` = 0

The structure of the pbq_idp_dev_actions table whose alias is 'a', is as follows

PRIMARY KEY (`dev_act_id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_520_ci
It would seem that everything is fine, but I get the following error and I don't understand why. The alias is correct, the field exists, yet the system can't find it.

The problem is in the wrong usage of backticks as can be seen in this example and the column action_expiration doesn't exist on pbq_idp_plan_actions table.
Backticks are used in MySQL to select Schema Object Names. Do not put the alias name inside backticks.
Not valid

MySQL use separate indices for JOIN and GROUP BY

I am trying to execute following query
SELECT
a.sessionID AS `sessionID`,
firstSeen, birthday, gender,
isAnonymous, LanguageCode
FROM transactions AS trx
INNER JOIN actions AS a ON a.sessionID = trx.SessionID
WHERE a.ActionType = 'PURCHASE'
GROUP BY trx.TransactionNumber
Explain provides the following output
1 SIMPLE trx ALL TransactionNumber,SessionID NULL NULL NULL 225036 Using temporary; Using filesort
1 SIMPLE a ref sessionID sessionID 98 infinitiExport.trx.SessionID 1 Using index
The problem is that I am trying to use one field for join and different field for GROUP BY.
How can I tell MySQL to use different indices for same table?
CREATE TABLE `transactions` (
`SessionID` varchar(32) NOT NULL DEFAULT '',
`date` datetime DEFAULT NULL,
`TransactionNumber` varchar(32) NOT NULL DEFAULT '',
`CustomerECommerceTrackID` int(11) DEFAULT NULL,
`SKU` varchar(45) DEFAULT NULL,

) ENGINE=InnoDB AUTO_INCREMENT=15042833 DEFAULT CHARSET=utf8;
Thanks
EDIT 1: My indexes were broken, I had to add (SessionID, TransactionNumber) index to transactions table, however now, when I try to include trx.customerInfoXML table mysql stops using index
EDIT 2 Another answer does not really solved my problem because it's not standard sql syntax and generally not a good idea to force indices.
For ORM users such syntax is a unattainable luxury.
EDIT 3 I updated my indices and it solved the problem, see EDIT 1

Field not inserting or updating , int type in sql

I am working on magento platform.I face a problem regarding values insertion to specific field: My query run perfect but one specific column not working for any query.I try my best but didn't find why .When i change the column type from int to varchar type it works.This is my table structure.
CREATE TABLE `followupemails_emaillogs` (
`id` int(8) NOT NULL AUTO_INCREMENT,
`schedule_time` datetime DEFAULT NULL,
`sent_time` datetime DEFAULT NULL,
`email_status` varchar(100) DEFAULT NULL,
`client_name` varchar(250) DEFAULT NULL,
`client_email` varchar(250) DEFAULT NULL,
`followupemails_id` int(11) DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=30 DEFAULT CHARSET=latin1.
the "followupemails_id" column not working in insert and update query.This is one update query where record exist that id(29). UPDATE followupemails_emaillogs SET followupemails_id=5 WHERE id =29.
This is insertion query INSERT INTO followupemails_emaillogs SET followupemails_id=4, schedule_time='2013-10-23 08:10:00', email_status='pending', client_name='ayaz ali'.this works fine on fiddle but not on my sqlyog ? what could be the issue.At last i find query that work perfect
.INSERT INTO followupemails_emaillogs (followupemails_id,schedule_time,email_status,client_name,client_email) VALUES (26,'2013-10-23 08:10:00','pending','ayaz ali','mamhmood#yahoo.com');
Can anyone tell me why set query not working but second query works perfect.so that i can accept his answer.Thanks for all your help
Try like this
To Create,
CREATE TABLE followupemails_emaillogs (
id int(8) NOT NULL AUTO_INCREMENT PRIMARY KEY,
schedule_time datetime DEFAULT NULL,
sent_time datetime DEFAULT NULL,
email_status varchar(100) DEFAULT NULL,
client_name varchar(250) DEFAULT NULL,
client_email varchar(250) DEFAULT NULL,
followupemails_i int(11) DEFAULT NULL,
UNIQUE (id)
)
To Insert,
INSERT INTO followupemails_emaillogs (schedule_time,sent_time,email_status,client_name,client_email,followupemails_i)
VALUES
('2012-05-05','2012-05-06',"sent","sagar","sagar#xxxx.com",2)
the whole query is ok
CREATE TABLE `followupemails_emaillogs` (
`id` int NOT NULL AUTO_INCREMENT,
`schedule_time` datetime DEFAULT NULL,
`sent_time` datetime DEFAULT NULL,
`email_status` varchar(100) DEFAULT NULL,

`client_email` varchar(250) DEFAULT NULL,
`followupemails_id` int DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=30 DEFAULT CHARSET=latin1.
but at the last there is dot which is actually error so remove the dot and create the table
latin1.
so remove the dot sign and not null in id filed use this line by default fields are null so don't use default null
id int (8) AUTO_INCREMENT
CREATE TABLE `followupemails_emaillogs` (
`id` int (8) AUTO_INCREMENT,
`schedule_time` datetime DEFAULT NULL,
`sent_time` datetime DEFAULT NULL,
`email_status` varchar(100),

`client_email` varchar(250),
`followupemails_id` int,
PRIMARY KEY (`id`),
UNIQUE KEY `id` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=30 DEFAULT CHARSET=latin1
don't need (11) in the sql query for int operator , This get for length of the nvarchar,varchar datatype column only not a int datatype,So change and write int instead of int(11) and int(8)
Try this query instead of your query
CREATE TABLE `followupemails_emaillogs` (
`id` int NOT NULL AUTO_INCREMENT,
`schedule_time` datetime DEFAULT NULL,
`sent_time` datetime DEFAULT NULL,
`email_status` varchar(100) DEFAULT NULL,

`followupemails_id` int DEFAULT NULL,

I m using mysql front 3.2 to manage database,I can add first fk but when i add second fk i got an error following this :
sql execution error #1005. response from the database: can't create table'.jobstatus#sql-32c_12f2f.frm' (errno:150). i already define the new index for fk subjobId reference to subjob table what could be the possibility of this error? thank you
Check the datatype and size of the subjobId column on primary table and referenced table. both must be same than it will allow you to create foreign key.
Answer is: You can not refer that column/table which is not created yet. Try to execute tables having foreign keys after the referenced tables.
Obviously you should have consistency in datatypes of foreign key and referenced column as well
Correct Execution Demo. Also You should use Engine=InnoDB instead of Type=InnoDB

why Mysql is giving me error 1280 "Wrong Index"

Can anyone explain why Mysql is giving me error 1280 ("wrong index for 'fk_chart_aid_aid' ") error whend I try to create the "CHART OF ACCOUNTS" table. I'm completly confused here. How can I fix this so I can create the table? The "ACCOUNT" table already exists in the database and has data in it.

Are you getting the error after the CREATE TABLE statement, or after the subsequent CREATE INDEX?
Looks like you are attempting to name both a FOREIGN KEY constraint and an INDEX fk_chart_aid_aid. Try choosing a different name for either one of them.
Also, in the accounts table, account_id is INT(10). Try also to change the column definition in acctg_chart_of_accounts to:
`account_id` INT(10) UNSIGNED NOT NULL ,
Though, I think that mysql defaults type INT to INT(10) anyway...
I met the same issue; tried manually rename the index to a different name but don't like the idea of 'manually' and neither I don't really understand why we need to generate the index separately. so I decide to generate it within the create statement by unchecking the option of 'generate separate index statement' in 'forwarding engineer', and this fix the issue.
