MYSQL Truncated incorrect DOUBLE value

When the SQL query below is executed:

UPDATE shop_category 
SET name = 'Secolul XVI - XVIII' 
    AND name_eng = '16th to 18th centuries' 
WHERE category_id = 4768

The following error is raised:

1292 - Truncated incorrect DOUBLE value: 'Secolul XVI - XVIII'

How to fix this?

shop_category table structure:

category_id   mediumint(8)
name        varchar(250)
name_eng      varchar(250)

You don't need the AND keyword. Here's the correct syntax of the UPDATE statement:

UPDATE 
    shop_category 
SET 
    name = 'Secolul XVI - XVIII', 
    name_eng = '16th to 18th centuries' 
WHERE 
    category_id = 4768

I was getting this exception not because of AND instead of comma, in fact I was having this exception just because I was not using apostrophes in where clause.

Like my query was

update table set coulmn1='something' where column2 in (00012121);

when I changed where clause to where column2 in ('00012121'); then the query worked fine for me.

What it basically is

It's incorrect syntax that causes MySQL to think you're trying to do something with a column or parameter that has the incorrect type "DOUBLE".

Learn from my mistake

In my case I updated the varchar column in a table setting NULL where the value 0 stood. My update query was like this:

UPDATE myTable SET myValue = NULL WHERE myValue = 0;

Now, since the actual type of myValue is VARCHAR(255) this gives the warning:

+---------+------+-----------------------------------------------+
| Level   | Code | Message                                       |
+---------+------+-----------------------------------------------+
| Warning | 1292 | Truncated incorrect DOUBLE value: 'value xyz' |
+---------+------+-----------------------------------------------+

And now myTable is practically empty, because myValue is now NULL for EVERY ROW in the table! How did this happen?

Over 30k rows now have missing data.

Thank goodness for backups. I was able to recover all the data.

The corrected query is as follows:

UPDATE myTable SET myValue = NULL WHERE myValue = '0';
                                                  ^^^
                                                  Quotation here!

I wish this was more than just a warning so it's less dangerous to forget those quotes.

Try replacing the AND with ,

UPDATE shop_category 
SET name = 'Secolul XVI - XVIII', name_eng = '16th to 18th centuries' 
WHERE category_id = 4768

The UPDATE Syntax shows comma should be used as the separator.
