MYSQL Truncated incorrect DOUBLE value

Question

When the SQL query below is executed:

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


        

Answer 1

I did experience this error when I tried doing an WHERE EXIST where the subquery matched 2 columns that accidentially was different types. The two tables was also different storage engines.

One column was a CHAR (90) and the other was a BIGINT (20).

One table was InnoDB and the other was MEMORY.

Part of query:

[...] AND EXISTS (select objectid from temp_objectids where temp_objectids.objectid = items_raw.objectid );

Changing the column type on the one column from BIGINT to CHAR solved the issue.
