在MySQL中删除ID字段

Question

I am new to MySQL databases and I have just imported my Access database into MySQL. When I did so, my primary key (ID) filed for one particular table is a bit messed up.

I would like all primary keys to be a number, but there is on that is showing up as a the height of a person. This is not present in the Access database.

I would add a picture but I cannot because I do not have the reputation yet... There is a 5' 7" in the ID place of an actual ID. When I attempt to delete this entry using the command

DELETE FROM actor_demographics WHERE ID=5' 7";

I am not able to delete the ID key. Any ideas?

Answer 1

DELETE FROM actor_demographics WHERE ID=5' 7";

MySQL不正确，应该是

DELETE FROM actor_demographics WHERE ID="5' 7\"";

Answer 2

It seems likely your ID column has a stringlike, not numberlike, data type.

Try using a string literal in your DELETE statement, thus

 DELETE FROM actor_demographics WHERE ID='5'' 7"';

Because you need a ' character in your string constant, double it to escape it.
