[mysql] Unknown column in 'field list' error on MySQL Update query

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' 

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.ymlhelped fix the problem.

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.

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!!!

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.

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);

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.

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.

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);

If it is hibernate and JPA. check your referred table name and columns might be a mismatch

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.

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.
