Good day,
I have an issue using the phpmyadmin for my database, I'm in new in this and this is the mysql structure from previewmysql:
CREATE TABLE `mydb`.`attendant`
(
`id` INT NOT NULL auto_increment,
`first_name` VARCHAR(20) NOT NULL,
`names` VARCHAR(50) NOT NULL,
`gender` ENUM(0) NOT NULL,
`email` VARCHAR(20) NOT NULL,
`phone` INT(15) NULL,
`marital_status` ENUM(0) NOT NULL,
`added_date` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
`membership` ENUM(0) NOT NULL,
`address` VARCHAR(20) NOT NULL,
`suburb` ENUM(0) NOT NULL,
`partner_name` VARCHAR(25) NULL,
PRIMARY KEY (`id`),
UNIQUE `email_address` (`email`)
)
engine = innodb;
The error is:
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 '0) NOT NULL , `email` VARCHAR(20) NOT NULL , `phone` INT(15) NULL , `marital_sta' at line 1
And also attached is my phpmyadmin table structure.
Will appreciate any help.
Try it.Hope errors goes boom.I just fixed your errors. But your table structure is not good enough. give time, then day by day you will also be expert on it.
CREATE TABLE `mydb`.`attendant`
(
`id` INT NOT NULL auto_increment,
`first_name` VARCHAR(20) NOT NULL,
`names` VARCHAR(50) NOT NULL,
`gender` ENUM('0','1') NOT NULL,
`email` VARCHAR(20) NOT NULL,
`phone` INT(15),
`marital_status` ENUM('0','1') NOT NULL,
`added_date` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
`membership` ENUM('0','1') NOT NULL,
`address` VARCHAR(20) NOT NULL,
`suburb` ENUM('0','1') NOT NULL,
`partner_name` VARCHAR(25) NULL,
PRIMARY KEY (`id`),
UNIQUE `email_address` (`email`)
)
engine = innodb;
Modify ENUM declaration as ENUM ('male', 'female') for gender column and others also as shown in your table. It will not accept ENUM(0).
ENUM(0) is wrong format , if you want that for gender roles then you can use :-
ENUM('Male', 'Female') i.e you can run this query :-
CREATE TABLE `mydb`.`attendant`
(
`id` INT NOT NULL auto_increment,
`first_name` VARCHAR(20) NOT NULL,
`names` VARCHAR(50) NOT NULL,
`gender` ENUM('Male', 'Female') NOT NULL,
`email` VARCHAR(20) NOT NULL,
`phone` INT(15) NULL,
`marital_status` ENUM('Single','Married','divorced') NOT NULL,
`added_date` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
`membership` ENUM('no','yes') NOT NULL,
`address` VARCHAR(20) NOT NULL,
`suburb` ENUM('Cape Town','Woodstock') NOT NULL,
`partner_name` VARCHAR(25) NULL,
PRIMARY KEY (`id`),
UNIQUE `email_address` (`email`)
)
engine = innodb;
You have used ENUM data type in your table. And provided 0 as argument but
An enumeration value must be a quoted string literal
You can refer the mySql documentation for more information
http://dev.mysql.com/doc/refman/5.7/en/enum.html

I'm learning MYSQL FULL JOIN queries using the Northwind database. This is my query,
SELECT customers.CompanyName, orders.OrderID
FROM customers
FULL JOIN orders ON customers.CustomerID=orders.CustomerID
ORDER BY customers.CompanyName;
Customers table schema,
CREATE TABLE `customers` (

And this is MySQL server version 5.7.35 - MySQL Community Server (GPL)
I am getting #1054 - Unknown column 'customers.CompanyName' in 'field list'
Can someone point out what I am doing wrong?
mysql don`t support full join,but oracle support
you can use
select customers.CompanyName, orders.OrderID from customers,orders where customers.CustomerID=orders.CustomerID order by
customers.CompanyName;
I am trying copy schema from one MYSQL database to other MYSQL database. While doing so few tables giving problem as follows
Error Code: 1064

Change DATETIME TO TIMESTAMP:
like this:
CREATE TABLE `auth_user` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`password` VARCHAR(128) NOT NULL,
`last_login` TIMESTAMP NOT NULL,

`date_joined` TIMESTAMP NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `username` (`username`)
) ENGINE=INNODB AUTO_INCREMENT=33 DEFAULT CHARSET=latin1;
MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD HH:MM:SS' format. The supported range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.You don't need to specify the length for datetime datatypes
DROP TABLE IF EXISTS `auth_user`;
CREATE TABLE `auth_user` (
`id` INT(11) NOT NULL AUTO_INCREMENT,

I created table as follows:
CREATE TABLE IF NOT EXISTS `products` (
`ID` tinyint(3) NOT NULL AUTO_INCREMENT,
`SKU` varchar(30) NOT NULL,
`Title` varchar(100) NOT NULL,
`Description` text NOT NULL,

`FancyCat` tinyint(3) NOT NULL,
`Active` tinyint(1) NOT NULL,
`SizeDescription` varchar(50) NOT NULL,
`Size` varchar(250) NOT NULL,
PRIMARY KEY (`ID`)
);
When importing data from CSV, it imports 127 lines then I get this error:
#1062 - Duplicate entry '127' for key 'PRIMARY'
You made the ID column a tinyint which can only take values from -127 to 127, larger values are truncated. Make it a regular int and things will work.
I have this MySQL query that I want to optimize:
SELECT r.WarehouseLocation,sum(sir.qty)
FROM repairableissue as r
INNER JOIN SIR ON r.sirno=sir.sirno
AND r.region=sir.region
AND r.ItemName=sir.Itemdesc
AND r.SerialNo=sir.Serialno
WHERE r.status='Pending'
GROUP BY r.warehouseLocation
How do I optimize this query? I read about optimization and found out that indexes might help but still could not achieve the desired performance.
Which index should be used and which should be removed?
Below is the explain of query:
Repairableissue
CREATE TABLE `repairableissue` (
`Vendor` varchar(40) NOT NULL,
`ItemName` varchar(200) NOT NULL,
`SerialNo` varchar(50) NOT NULL,

`WarehouseLocation` varchar(20) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id` (`id`),
KEY `I1` (`status`),
KEY `ind2` (`ItemName`),
KEY `ind3` (`region`),
KEY `ind5` (`SerialNo`),
KEY `ind4` (`Sirno`)
) ENGINE=MyISAM AUTO_INCREMENT=63029 DEFAULT CHARSET=latin1
sir
CREATE TABLE `sir` (
`SirNo` varchar(50) NOT NULL,
`SiteId` varchar(80) NOT NULL,
`Vendor` varchar(70) NOT NULL,
`Type` varchar(15) NOT NULL,

`WarehouseLocation` varchar(20) NOT NULL,
`mainpartserial` varchar(200) NOT NULL,
PRIMARY KEY (`Vendor`,`Type`,`ItemCode`,`ItemDesc`,`SerialNo`,`Ownership`,`SirNo`,`Region`,`WarehouseType`,`WarehouseLocation`,`po`,`Qty`,`id`),

KEY `ind7` (`SerialNo`)
) ENGINE=MyISAM AUTO_INCREMENT=228007 DEFAULT CHARSET=latin1
One multi-column index on r.status + r.warehouseLocation, in that order.
One multi-column index on sir.sirno + sir.region + sir.Itemdesc + sir.Serialno, in order of most cardinality to least cardinality, with sir.qty tacked on the end.
This assumes the fields are small enough to fit (combined) into an index.
Still, join seeks are unavoidable. The number of records that match r.status='Pending' is going to dictate the speed of this query.
Below is my mysql query
SELECT
opensalesorder.so_number,
items.VendorName,
opensalesorder.item_number,
items_custom_fields.FieldValue AS `Stock Item`,
vendor_custom_fields.FieldValue AS `Paid Freight Allowance`,
items.QuantityOnHand,
items.ReorderPoint,
items.MaxQty,
SUM(opensalesorder.quantity_on_order),
items.PurchaseCost,
items.VendorName,
items.VendorName,
items.PurchaseCost,
opensalesorder.status,
items.ItemType
FROM
vendor,
`opensalesorder`
inner join items
on opensalesorder.item_number = items.ItemName
JOIN items_custom_fields
ON items_custom_fields.ItemName = items.ItemName
JOIN vendor_custom_fields
ON vendor_custom_fields.VName = vendor.VName
WHERE opensalesorder.item_number = items.ItemName
and items_custom_fields.FieldName ='Stock Item'
and vendor_custom_fields.FieldName ='Paid Freight Allowance'
and opensalesorder.status NOT LIKE 'on po'
AND opensalesorder.so_number NOT IN ('2','3')
AND items.VendorName NOT IN ('Access')
AND opensalesorder.item_number NOT IN ('018-0001')
group by opensalesorder.item_number
LIMIT 100
on executing this query I am getting error like
#1054 - Unknown column 'vendor.VName' in 'on clause'
But I have included the vendor table in FROM clause.
Is this right way to include a table in JOIN ?
So whats wrong is with this query ?

I think the problem is mixing the implied join with the (unimplied) 'stated' joins. When I put 'vendor' in as a regular join the query was fine.
(I had to comment out references to 'items_custom_fields' as you didn't include the table definition)
Here's a fiddle.
