SQL Query 3rd term date - mysql

INSERT INTO `empleado` VALUES ('100', 'Alfonso', '1999-11-22', '100', '11');
INSERT INTO `empleado` VALUES ('101', 'Encarna', '2001-11-12', '100', '15');
INSERT INTO `empleado` VALUES ('102', 'Paco', '1999-10-16', '101', '12');
INSERT INTO `empleado` VALUES ('103', 'Juan Carlos', '1999-01-12', '101', '10');
That's my Date Type ,I need to select some codes that got into the company in the 3rd term of 1999
"select nombre,coddep,fecha_ingreso from
empleado where fecha_ingreso >1999;"
-that was my initial query, but it's wrong since it selects the name,cod and datetime >1999


This will fetch rows in the 3rd calendar quarter of 1999:
SELECT nombre, coddep, fecha_ingreso
FROM empleado
WHERE fecha_ingreso BETWEEN '1999-07-01' AND '1999-09-30'
If the field is DATETIME rather than DATE, change the second date to 1999-09-30 12:59:59


SELECT nombre, coddep, fecha_ingreso
FROM empleado
WHERE YEAR(fecha_ingreso) = 1999 AND QUARTER(fecha_ingreso) = 3
;

I am receiving duplicate column name, but based on values. When i change the value, there is no error

I am trying to use this query, but when there are the same value in different columns, I receive this error:
1060 - Duplicate column name "123"
For example here:
INSERT INTO chiro(in_out,chirocov,chirocov2,chiroded,chiromet,
chirocovp,chirooop,chirooopmet,chirooopcp,
chirovisit,chirouse,chiromax,chirodedapply,
chironum1,chironum2)
SELECT * FROM (SELECT 'in', 'no','individual','123','123','20',
'213','21243','10','14','5','2000','yes',
'0','1') AS tmp
WHERE NOT EXISTS (SELECT in_out,chirocov,chirocov2,
chiroded,chiromet,chirocovp,chirooop,
chirooopmet,chirooopcp, chirovisit,chirouse,
chiromax,chirodedapply,chironum1,chironum2
FROM chiro
WHERE chirocov='no'
AND chirocov2='individual'
AND chiroded='123'
AND chiromet='123'
AND chirocovp='20'
AND chirooop='213'
AND chirooopmet='213'
AND chirooopcp='10'
AND chirovisit='14'
AND chirouse='5'
AND chiromax='2000'
AND chirodedapply='yes'
AND chironum1='0'
AND chironum2='1')
LIMIT 1
But when i change the value, there won"t be any errors. like:
INSERT INTO chiro(in_out,chirocov,chirocov2,chiroded,
chiromet,chirocovp,chirooop,chirooopmet,
chirooopcp, chirovisit,chirouse,chiromax,
chirodedapply,chironum1,chironum2)
SELECT * FROM (SELECT 'in', 'no','individual','123','231','20',
'213','21243','10','14','5','2000',
'yes', '0','1') AS tmp
WHERE NOT EXISTS (SELECT in_out,chirocov,chirocov2,
chiroded,chiromet,chirocovp,chirooop,
chirooopmet,chirooopcp, chirovisit,chirouse,
chiromax,chirodedapply,chironum1,chironum2
FROM chiro
WHERE chirocov='no'
AND chirocov2='individual'
AND chiroded='123'
AND chiromet='123'
AND chirocovp='20'
AND chirooop='213'
AND chirooopmet='213'
AND chirooopcp='10'
AND chirovisit='14'
AND chirouse='5'
AND chiromax='2000'
AND chirodedapply='yes'
AND chironum1='0'
AND chironum2='1')
LIMIT 1
Could you help me and let me know what I am doing wrong?

Just remove the outer SELECT from:
SELECT * FROM (SELECT 'in', 'no','individual','123','123','20',
'213','21243','10','14','5','2000','yes',
'0','1') AS tmp
because it retrieves all the unnamed columns from the inner select with names that are their values, so there are 2 columns with the same name 123.
See a simplified demo of the problem.
Use this:
INSERT INTO chiro(
in_out, chirocov, chirocov2, chiroded, chiromet, chirocovp, chirooop, chirooopmet, chirooopcp,
chirovisit, chirouse, chiromax, chirodedapply, chironum1, chironum2
)
SELECT 'in', 'no', 'individual', '123', '123', '20', '213', '21243', '10', '14', '5', '2000', 'yes', '0', '1'
WHERE NOT EXISTS(
SELECT in_out, chirocov, chirocov2, chiroded, chiromet, chirocovp, chirooop, chirooopmet, chirooopcp,
chirovisit, chirouse, chiromax, chirodedapply, chironum1, chironum2
FROM chiro
WHERE chirocov='no' AND chirocov2='individual' AND chiroded='123' AND chiromet='123' AND chirocovp='20'
AND chirooop='213' AND chirooopmet='213' AND chirooopcp='10' AND chirovisit='14' AND chirouse='5'
AND chiromax='2000' AND chirodedapply='yes' AND chironum1='0' AND chironum2='1'
)
Also LIMIT 1 is not necessary.

Create WordPress User With MySQL Query

Trying to create a new WordPress user directly through MySQL by running a query. I keep seeing an error message popup :
1292 - Incorrect datetime value: '0000-00-00 00:00:00' for column 'user_registered' at row 1
How can include what is missing?
INSERT INTO `wp_users` (`user_login`, `user_pass`, `user_nicename`, `user_email`, `user_status`)
VALUES ('adminuser2', MD5('adminuser2password'), 'adminfirstname adminlastname', 'adminuser2#mywebsite.com', '0');
INSERT INTO `wp_usermeta` (`umeta_id`, `user_id`, `meta_key`, `meta_value`)
VALUES (NULL, (Select max(id) FROM wp_users), 'wp_capabilities', 'a:1:{s:13:"administrator";s:1:"1";}');
INSERT INTO `wp_usermeta` (`umeta_id`, `user_id`, `meta_key`, `meta_value`)
VALUES (NULL, (Select max(id) FROM wp_users), 'wp_user_level', '10');

Follow this syntax, it's the recommended way to insert data while you're using WordPress
$wpdb->insert( $table_name, array('column_name_1'=>'hello', 'other'=> 123), array( '%s', '%d' ) );
define a variable:
$blogtime = current_time( 'mysql' ); then add 'user_registered' column to your query
$wpdb->insert( 'wp_users' , array(
'user_login' => 'adminuser2',
'user_pass' => MD5('adminuser2password'),
'user_nicename'=> 'adminfirstname adminlastname',
'user_email'=> 'adminuser2#mywebsite.com',
'user_status'=> '0',
'user_registered'=> '$blogtime'
));

My code is only returning two of the five entries I need, how can I fix this problem?

I am trying to create a list of employees showing their first name, hire date, and the city where they work. There are five employees listed but when I run my problem it only returns the first two from the location data entry.
Shown first is my employee data entered. When I run a select * statement for this table everything appears as it should. The problem comes when I try to run the second script shown, where it only shows the first two entries from the employee table.
first
INSERT INTO `salon`.`employee`
(`employee_id`,

mysql: find newest non null values

I have a huge table with 100 fields. Each row is timestamped. I want to find the latest non null value for all columns. I'm using MySql 5.6 InnoDB
e.g.
create table tester(
pub_id int,
pub_name varchar(20),
pub_city varchar(20),
country varchar(20),
no_of_branch varchar(20),
estd datetime
);
insert into tester (pub_id, pub_name, pub_city, country, estd)
values
(1, 'a', 'xyz', 'abcity' , 'a', '1970-01-01 00:00:01'),
(2, 'a', 'xyz', '' , 'a', '1971-01-01 00:00:01'),
(3, 'a', 'xyz', 'abcity1', 'b', '1972-01-01 00:00:01'),
(4, 'a', 'xyz', '' , 'a', '1973-01-01 00:00:01'),
(5, 'a', 'xyz', 'abcity2', '' , '1974-01-01 00:00:01'),
(6, 'b', 'lmn', 'abcity' , 'a', '1974-01-01 00:00:01'),
(7, 'b', 'xyz', '' , 'a', '1975-01-01 00:00:01'),
(8, 'b', 'sdf', 'abcity1', 'b', '1976-01-01 00:00:01'),
(9, 'b', '' , '' , 'a', '1977-01-01 00:00:01'),
(10, 'b', '' , 'abcity2', '' , '1978-01-01 00:00:01');
I want to query that would give me:
'a', 'xyz', 'abcity2', 'a'
'b', 'sdf', 'abcity2', 'b'
I don't want to use a query where i find empty values for each column of the table individually and then take a join as this would be a very cumbersome task given that my actual table has 100 columns.
I have searched for a solution for the past of couple of ours and found nothing. ANy help would be greatly appreciated.
Thanks

This might be the "tricky" way you are looking for.
First create a twin table (tester2) to receive the aggregated data. This new table must have a primary key on pub_name and all the columns you want to aggregate. Then do an INSERT INTO ON DUPLICATE KEY UPDATE. This query will basically rebuild the tester table but without duplicate and with aggregated data. In fact something like this :
insert into tester2 (pub_name, pub_city, country, no_of_branch)
select pub_name, pub_city, country, no_of_branch FROM tester order by estd desc
on duplicate key
update
pub_city = coalesce(tester2.pub_city,tester.pub_city),
country = coalesce(tester2.country,tester.country),
no_of_branch = coalesce(tester2.no_of_branch,tester.no_of_branch)
The content of tester2 will be :
PUB_NAME PUB_CITY COUNTRY NO_OF_BRANCH
a xyz abcity2 a
b sdf abcity2 a
Have a look the DB Fiddle.
Note : I assume you mean real NULL values and not empty string like the sample you provided.

INSERT in some tables's Simultaneous in MYSQL

I try to insert my data to some table's of database I have tried the following:
INSERT INTO tbl_18189 (a,b,c,d,e) VALUES ( '1', '4 B', '%', '0', '0')
INSERT INTO tbl_3823 (a,b,c,d,e) VALUES ( '24000', '30 M', '34%', '885', '12.05')
INSERT INTO tbl_67126 (a,b,c,d,e) VALUES ( '3.99 M', '10 B', '10%', '530', '14.41')
INSERT INTO tbl_4247 (a,b,c,d,e) VALUES ( '1', '170 M', '%', '271', '22.77')
INSERT INTO tbl_23838 (a,b,c,d,e) VALUES ( '320000', '400 M', '7%', '407', '6.91')
but I got
Error creating table: 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 'INSERT INTO tbl_38232 ...
where is the problem in my code

UNION ALL joins SELECTs and you have none in your example. Remove them.

INSERT INTO tbl_18189 (a,b,c,d,e) VALUES ( '1', '4 B', '%', '0', '0');
INSERT INTO tbl_3823 (a,b,c,d,e) VALUES ( '24000', '30 M', '34%', '885', '12.05');
INSERT INTO tbl_67126 (a,b,c,d,e) VALUES ( '3.99 M', '10 B', '10%', '530', '14.41');
INSERT INTO tbl_4247 (a,b,c,d,e) VALUES ( '1', '170 M', '%', '271', '22.77');
INSERT INTO tbl_23838 (a,b,c,d,e) VALUES ( '320000', '400 M', '7%', '407', '6.91');
