Joining doesn't work when columns include apostrophes

I'm trying to update id's in a table where the corresponding unique id is currently stored in another table.

Currently, the table structure is something like this:

Table 1

id name
1 As
2 Bs
3 C's

Table 2

id name pay
null As 100
null Bs 200
null C's 300
UPDATE table2 t2
JOIN table1 t1 ON t2.name = t1.name
SET t2.id = t1.id

When I update the id's in table 2 by joining the names using the query above As and Bs get the correct id's, but all fields like C's don't find a match and result in having null id fields like below.

Result

id name pay
1 As 100
2 Bs 200
null C's 300

Desired Result

id name pay
1 As 100
2 Bs 200
3 C's 300

Any way to get mySQL to correctly join names with apostrophes in them?

CodePudding user response:

Apostrophe types were inconsistent.

In the comments @ysth mentioned there were different characters that are sometimes used as apostrophes, so replacing them all with the standard (') fixed most of the issues.
