This is my Database structure for two tables
CREATE TABLE `futstkrprices` (
`name` varchar(50) DEFAULT NULL,
`expiry_date` varchar(25) DEFAULT NULL,
`contract_type` varchar(50) DEFAULT NULL,
`close_price` decimal(15,2) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
CREATE TABLE `historical_data` (
`symbol_name` varchar(70) DEFAULT NULL,
`open_val` decimal(15,2) DEFAULT NULL,
`high_val` decimal(15,2) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
INSERT INTO futstkrprices (name,expiry_date,contract_type,close_price)
values ('ABIRLANUVO' ,'26-MAY-2016','FUTSTK',870.65);
INSERT INTO futstkrprices (name,expiry_date,contract_type,close_price)
values ('ABIRLANUVO' ,'28-APR-2016','FUTSTK',866.40);
INSERT INTO futstkrprices (name,expiry_date,contract_type,close_price)
values ('ABIRLANUVO' ,'30-JUN-2016','FUTSTK',875.95);
INSERT INTO historical_data (symbol_name,open_val,high_val) values ('ABIRLANUVO',872.00,878.25)
Here is the sample Fiddle
http://sqlfiddle.com/#!9/1d4f20
Could you please tell me how can i retrieve data from both the tables
I have tried it as , but its not working
select futstkrprices.name , futstkrprices.expiry_date , futstkrprices.close_price , historical_data.symbol_name ,
historical_data.open_val , historical_data.high_val from futstkrprices LEFT JOIN futstkrprices
ON futstkrprices.name=historical_data.symbol_name;
The desired output i am expecting is
name expiry_date close_price symbol_name open_val high_val
ABIRLANUVO 26-MAY-2016 870.65 ABIRLANUVO 872 878.25
ABIRLANUVO 28-APR-2016 866.4 ABIRLANUVO 872 878.25
ABIRLANUVO 30-JUN-2016 875.95 ABIRLANUVO 872 878.25
Yuou have repetead two times the same table from futstkrprices LEFT JOIN futstkrprices
try this
select
futstkrprices.name ,
futstkrprices.expiry_date ,
futstkrprices.close_price ,
historical_data.symbol_name ,
historical_data.open_val ,
historical_data.high_val
from futstkrprices
LEFT JOIN historical_data
ON futstkrprices.name=historical_data.symbol_name;

3 tables. I want oc_tax_class.title = oc_tax_rate.name
I believe, although I'm not sure, that I should
INSERT INTO oc_tax_class(title)
or
UPDATE oc_tax_class SET title = ...
SELECT oc_tax_rate.name, oc_tax_rule.tax_class_id
JOIN oc_tax_rule ON oc_tax_rate.tax_rate_id = oc_tax_rule.tax_rate_id
And then I don't know what to do next.
I need to copy values from one column to another table, passing through a connecting table.
MySQL supports a multi-table UPDATE syntax, but the documentation (https://dev.mysql.com/doc/refman/en/update.html) has pretty sparse examples of it.
In your case, this may work:
UPDATE oc_tax_class
JOIN oc_tax_rule USING (tax_class_id)
JOIN oc_tax_rate USING (tax_rate_id)
SET oc_tax_class.title = oc_tax_rate.name;
I did not test this. I suggest you test it first on a sample of your data, to make sure it works the way you want it to.
Im trying to get a query to only return a single row for each unique ID.
given the following:
CREATE TABLE `groups` ( `id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(45) DEFAULT NULL, `type` int(1) DEFAULT NULL,
`date` datetime DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB
AUTO_INCREMENT=5 DEFAULT CHARSET=latin1;
CREATE TABLE `groupmembers` ( `id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL, `readmessage` int(1) DEFAULT
NULL, `status` int(1) DEFAULT NULL, `group_id` int(20) DEFAULT
NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT
CHARSET=latin1;
CREATE TABLE `messages` ( `id` bigint(10) NOT NULL AUTO_INCREMENT,
`send_to` varchar(50) NOT NULL DEFAULT '', `name` varchar(50) NOT
NULL DEFAULT '', `email` varchar(50) NOT NULL DEFAULT '',
`subject` varchar(100) NOT NULL DEFAULT 'No Subject', `message`
longtext NOT NULL, `timestamp` timestamp NOT NULL DEFAULT
CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `message_read`
enum('Yes','No') NOT NULL DEFAULT 'No', `send_time` datetime NOT
NULL DEFAULT '1970-01-01 00:00:00',
`hide_message` enum('0','1') NOT NULL, `grouper` int(20) DEFAULT
NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT
CHARSET=latin1;
insert into groups (type,date) values ('0',now());
insert into groupmembers (username,group_id) values ('user1',5),('user2',5);
insert into messages (send_to,name,send_time,grouper,message) values
('user1','user2','2019-10-09 19:18:12',5,'hello');
insert into messages (send_to,name,send_time,grouper,message) values
('','user2','2019-10-10 09:18:39',5,'hello');
In mysql 5.6 this query works as anticipated:
select groups.id,send_to,messages.name,max(send_time) from groups
inner join messages on groups.id=messages.grouper left join
groupmembers on groups.id=groupmembers.group_id where
groupmembers.username='user1' group by groups.id ORDER BY
MAX(send_time)
in mysql 5.7 this returns an error
Error Code: 1055. Expression #2 of SELECT list is not in GROUP BY
clause and contains nonaggregated column 'messages.send_to' which is
not functionally dependent on columns in GROUP BY clause; this is
incompatible with sql_mode=only_full_group_by
What do I need to do to get this to work in MySQL 5.7 without adjusting the SQL Mode?
See SQL Fiddle here: http://sqlfiddle.com/#!9/9061da/4
It works as expected on the SQL fiddle as that is running 5.6.
Just a guess...
SELECT DISTINCT g.id
, m.send_to
, m.name
, m.send_time
FROM groups g
JOIN messages m
ON m.grouper = g.id
JOIN
( SELECT send_to
, name
, MAX(send_time) send_time
FROM messages m
GROUP
BY send_to
, name
) x
ON x.send_to = m.send_to
AND x.name = m.name
AND x.send_time = m.send_time
JOIN groupmembers gm
ON gm.group_id = g.id
WHERE gm.username = 'user1'
ORDER
BY send_time;

when I run the following query I get the first table's record correctly but the second table's record showing NULL values
SELECT * FROM users
LEFT JOIN installments
ON users.id=installments.installment_id
WHERE users.cnic='37406-3140185-1';
Is there anything missing in the above query or is there another way to get the record from both tables simultaneously
id user_name password father_name phone cnic email address introducer date reg_number installment user_level installment_id month prv_arrear amount total receive arrear fk_users_id

I am also using the following query to inserting the record for getting primary key value and insert into foreign key
INSERT INTO `installments`(`id`, `month`, `prv_arrear`, `amount`, `total`, `receive`, `arrear`, fk_users_id)
SELECT NULL,now(),1000,2500,3500,3000,500, id
FROM users
WHERE cnic = '37406-3140190-1'
please help me thanks in advance and sorry if there is something wrong in my question because I am new in sql.
I suspect the right join condition is on fk_users_id. So this might do what you want:
SELECT *
FROM users u LEFT JOIN
installments i
ON u.id = i.fk_users_id
WHERE u.cnic = '37406-3140185-1';
