What is wrong with this MySQL UPDATE syntax? [duplicate] - mysql

This question already has answers here:
What is the difference between the backtick and the square bracket in SQL statements?
(2 answers)
Closed 7 years ago.
SET #currentID = (SELECT MIN(ExperimentID) FROM Jobs_t WHERE JobStatus = 'ToRun');
UPDATE [Jobs_t]
SET [JobStatus] = 'Pending'
WHERE ExperimentID = #currentID;
SELECT #currentID
Jobs_t is a table with two columns, ExperimentID and JobStatus. My SQL syntax is wrong on line 2, UPDATE [Jobs_t], but I can't seem to find out why.
I updated the syntax to:
SET #currentID = (SELECT MIN(`ExperimentID`) FROM `Jobs_t` WHERE `JobStatus` = 'ToRun');
UPDATE `Jobs_t`
SET `JobStatus` = 'Pending'
WHERE `ExperimentID` = #currentID;
SELECT #currentID
But it still fails on that second line.
The full error message is:
System.Data.Odbc.OdbcException: ERROR [42000] [MYSQL][ODBC 5.3(a) Driver][mysqld-5.7.9-log]
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 'UPDATE Jobs_t SET JobStatus = 'Pending' WHERE `ExperimentID = #currentID; S' at line 2

Trying this as an answer. Change
[Jobs_t]
to
`Jobs_t`
The character below the ~ on the top left of your keyboard. Change that for all instances of your brackets.

Update records with JOIN command

I have the following query that works great and shows me where the tbl_staff.staff_id and tbl_lead.rlog_create_user_id values do not match.
SELECT
tbl_staff.staff_id,
tbl_staff.username,
tbl_lead.rlog_create_user_name,
tbl_lead.rlog_create_user_id
FROM
tbl_staff
JOIN tbl_lead ON tbl_staff.username = tbl_lead.rlog_create_user_name
AND tbl_staff.staff_id <> tbl_lead.rlog_create_user_id;
The query returns values like this where you can see the 1014 does not match the 1004.
1014 bubba bubba 1004
I want to update the value in the tbl_lead.rlog_create_user_id to the same value as is found in tbl_staff.staff_id.
I tried to insert a SET command but it's giving me a generic syntax error:
SELECT
tbl_staff.staff_id,
tbl_staff.username,
tbl_lead.rlog_create_user_name,
tbl_lead.rlog_create_user_id
FROM
tbl_staff
JOIN tbl_lead ON tbl_staff.username = tbl_lead.rlog_create_user_name
AND tbl_staff.staff_id <> tbl_lead.rlog_create_user_id
SET tbl_lead.rlog_create_user_id=tbl_staff.staff_id ;
The actual error is:
[Err] 1064 - 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 'SET tbl_lead.rlog_create_user_id=tbl_staff.staff_id' at line
10
I tried to change the SELECT to and UPDATE command using this question but still could not get it working: How can I do an UPDATE statement with JOIN in SQL?
Try this
UPDATE tbl_lead
JOIN tbl_staff ON tbl_staff.username = tbl_lead.rlog_create_user_name
SET tbl_lead.rlog_create_user_id = tbl_staff.staff_id
WHERE tbl_staff.staff_id <> tbl_lead.rlog_create_user_id;
Have you tried like this ?
UPDATE tbl_staff, tbl_lead
SET tbl_lead.rlog_create_user_id = tbl_staff.staff_id
WHERE tbl_staff.username = tbl_lead.rlog_create_user_name

Syntax error when updating columns

I'm trying to use the following code to update columns:
UPDATE user_profiles
SET range = '20', colResize = 'flex'
WHERE uid='472';
I get the following error:
Failed to execute SQL : SQL UPDATE user_profiles SET range = '20', colResize = 'flex' WHERE uid='472'; failed : 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 'range = '20', colResize = 'flex' WHERE uid='472'' at line 1
What am I overlooking?
range is a reserved keyword in MySQL. Use backticks to escape the name or use another column name.
SET `range` = 20

UPDATE with logical AND operator

I tried running this sql
UPDATE table
SET read = 1
WHERE col1_id = 2
AND col3_id = 1;
and it return an error (error in your sql syntax)
#1064 - 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 'read = 1 WHERE team_notification_id = 2 AND listener_id = 1' at line 1
But when I used thesame WHERE and AND :), in a SELECT statement no error was returned.
SELECT *
FROM read
WHERE col1_id = 2
AND col3_id = 1
please what did I do wrong, I am no seeing it.
After keyword UPDATE there should be a table name. If your table has actually name table (that's a bit strange) you should escape it to let MySQL know it's not a keyword "table" but actual table name.
The same thing is about read.
Both table and read are MySQL keywords (the full list is here http://dev.mysql.com/doc/refman/5.7/en/keywords.html) so if it's your actual table and column names then you should escape it.
Better to escape all table and column names to prevent issues like that.
Escaping in MySQL is done with backtick symbol ` so your query will looks like:
UPDATE `table`
SET `read` = 1
WHERE `col1_id` = 2
AND `col3_id` = 1;
UPDATE tablename
SET `field_name` = 1
WHERE col1_id = 2
AND col3_id = 1;
UPDATE table
SET [read] = 1
WHERE col1_id = 2
AND col3_id = 1;

SQL Syntax Error in PHP code - adding together two values

I keep getting this syntax error in my MySQL code within a PHP file. I'm simply trying to increment/add to the value already in the table with this time variable. If anyone could help me out I'd greatly appreciate it.
PHP:
$sql = "UPDATE Aircraft
SET MaintenanceFlightTime = (MaintenanceFlightTime + $MaintenanceDuration),
WHERE AircraftID = $AircraftID";
Error:
UPDATE Aircraft SET MaintenanceFlightTime = (MaintenanceFlightTime + 00:10:00), WHERE AircraftID = 8
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ':10:00), WHERE AircraftID = 8' at line 2
You cannot just add a string like '01:01:01' to a time column but you can use ADDTIME()
$MaintenanceDuration = '00:10:00';
$sql = "UPDATE Aircraft
SET MaintenanceFlightTime = ADDTIME(MaintenanceFlightTime, '$MaintenanceDuration')
WHERE AircraftID = $AircraftID";

mySQL UPDATE failed. What is wrong with this mySQL UPDATE query?

here's the generated query:
UPDATE namelist
SET 'submitterName' = 'Jim'
,'actorName' = 'dingle'
,'setYear' = '1103'
,'country' = 'tanata'
,'blink' = 'on'
,'crush' = 'on'
,'initialize' = 'on'
,'entered' = 'on'
,'stuck' = 'on'
,'catapult' = 'on'
,'ruck' = 'on'
WHERE id = 31
it generates this (less than helpful) 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 (query snippet) at line 1
for the life of me, i can't spot where the problem is. yes, column names match, yes
TIA for helping out.
WR!
You have used single quotes before and after columns in the query, replace those single quotes with backquotes.
So the query like
UPDATE namelist
SET `submitterName`='Jim',
`actorName`='dingle',
`setYear`='1103',
`country`='tanata',
`blink`='on',
`crush`='on',
`initialize`='on',
`entered`='on',
`stuck`='on',
`catapult`='on',
`ruck`='on'
WHERE id=31;
user ` instead of '
like this
UPDATE namelist SET `submitterName`='Jim',`actorName`='dingle',`setYear`='1103',`country`='tanata',`blink`='on',`crush`='on',`initialize`='on',`entered`='on',`stuck`='on',`catapult`='on',`ruck`='on' WHERE id=31
