Unknown column in 'field list' error on MySQL Update query
MysqlSqlMysql Error-1054Mysql Problem Overview
I keep getting MySQL error #1054, when trying to perform this update query:
UPDATE MASTER_USER_PROFILE, TRAN_USER_BRANCH
SET MASTER_USER_PROFILE.fellow=`y`
WHERE MASTER_USER_PROFILE.USER_ID = TRAN_USER_BRANCH.USER_ID
AND TRAN_USER_BRANCH.BRANCH_ID = 17
It's probably some syntax error, but I've tried using an inner join instead and other alterations, but I keep getting the same message:
Unknown column 'y' in 'field list'
Mysql Solutions
Solution 1 - Mysql
Try using different quotes for "y" as the identifier quote character is the backtick (`). Otherwise MySQL "thinks" that you point to a column named "y".
See also MySQL 8 Documentation
Please use double-/single quotes for values, strings, etc. Use backticks for column-names only.
Solution 2 - Mysql
Enclose any string to be passed to the MySQL server inside single quotes, e.g.:
$name = "my name"
$query = " INSERT INTO mytable VALUES ( 1 , '$name') "
Note that although the query is enclosed between double quotes, you must enclose any string in single quotes.
Solution 3 - Mysql
You might check your choice of quotes (use double-/ single quotes for values, strings, etc and backticks for column-names).
Since you only want to update the table master_user_profile
I'd recommend a nested query:
UPDATE
master_user_profile
SET
master_user_profile.fellow = 'y'
WHERE
master_user_profile.user_id IN (
SELECT tran_user_branch.user_id
FROM tran_user_branch WHERE tran_user_branch.branch_id = 17);
Solution 4 - Mysql
In my case, it was caused by an unseen trailing space at the end of the column name. Just check if you really use "y" or "y " instead.
Solution 5 - Mysql
Just sharing my experience on this. I was having this same issue. The insert or update statement is correct. And I also checked the encoding. The column does exist. Then! I found out that I was referencing the column in my Trigger. You should also check your trigger see if any script is referencing the column you are having the problem with.

While working on a .Net app build with EF code first, I got this error message when trying to apply my migration where I had a Sql("UPDATE tableName SET columnName = value");
statement.
Turns out I misspelled the columnName.
Solution 7 - Mysql
Just sharing my experience on this. I was having this same issue. My query was like:
select table1.column2 from table1
However, table1 did not have column2 column.
Solution 8 - Mysql
If it is hibernate and JPA. check your referred table name and columns might be a mismatch
Solution 9 - Mysql
In my case, the Hibernate was looking for columns in a snake case, like create_date
, while the columns in the DB were in the camel case, e.g., createDate
.
Adding
spring:
jpa:
hibernate:
naming: # must tell spring/jpa/hibernate to use the column names as specified, not snake case
physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
implicit-strategy: org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
to the application.yml
helped fix the problem.
Solution 10 - Mysql
In my case, I used a custom table alias for the FROM
table, but I used the default table alias (MyTable
) in the field list instead of the custom table alias (t1
). For example, I needed to change this...
mysql> SELECT MyTable.`id` FROM `MyTable` t1;
...to this...
mysql> SELECT t1.`id` FROM `MyTable` t1;
Solution 11 - Mysql
A query like this will also cause the error:
SELECT table1.id FROM table2
Where the table is specified in column select and not included in the from clause.
Solution 12 - Mysql
I too got the same error, problem in my case is I included the column name in GROUP BY
clause and it caused this error. So removed the column from GROUP BY
clause and it worked!!!
Solution 13 - Mysql
I got this error when using GroupBy via LINQ on a MySQL database. The problem was that the anonymous object property that was being used by GroupBy did not match the database column name. Fixed by renaming anonymous property name to match the column name.
.Select(f => new
{
ThisPropertyNameNeedsToMatchYourColumnName = f.SomeName
})
.GroupBy(t => t.ThisPropertyNameNeedsToMatchYourColumnName);
Solution 14 - Mysql
In my case I had misspelled the column name in the table's trigger. Took me a while to connect the error message with the cause of it.
