#Mysql change column manual#

I've never been able to successfully alter a VARCHAR in this DB, if I specify collation. changing column name has the same error.) And I've had this problem before on other tables. It doesn't matter what I attempt to change (e.g. It doesn't matter what values I use for VARCHAR length.Something about the COLLATE? But that is the collate we use throughout this DB. I can change INT columns in the same table (e.g. In MySQL, the ALTER COLUMN subclause can only be used for setting or dropping the default value of the column (SET DEFAULT literal or DROP DEFAULT).I see nothing in the release log about this behaviour. This happened on MySQL 5.7.19, but as far as I can remember it did not happen locally on MySQL 5.7.18, I add to modify each column as per this answer. Is just something wrong with that ALTER TABLE syntax. I noticed that just changing table charset/collation automatically changes the columns charset/collation no need to change individual columns. Works fine if I delete the column, then recreate it with these same settings.All I did was change the VARCHAR length.I don't see what is wrong with the query, and would like to know what is wrong.

#1064 - You have an error in your SQL syntax check the manual that corresponds to your MYSQL server version for the right syntax to user near '=latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL' at line 1. When attempt to execute that SQL, get error message via phpmyadmin: This line of code was generated automatically by phpmyadmin (perhaps an old version running on my company's website, but I don't want to deal with that right now): ALTER TABLE `lc_error_logs` CHANGE `OneDetailedMessage` `OneDetailedMessage` VARCHAR(5000) CHARSET=latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL
