Update / Answer
To fix this issue, I added the keyword BINARY to each side of the comparison operator. This generated the expected results. Also note that I set the variable to empty string. Setting this to NULL did not resolve the issue.
SET #previousstate = '';
SELECT
if(**BINARY** #previousstate != **BINARY** frm.fi_details_temp.PortfolioCode,
End Update / Answer
This is somewhat related to MYSQL Stored Procedure - Concat Row Value. That thread was based on Mysql 5.7.
The following statement worked under MySQL 5.7. I am in the process of trying to get it to work in MySql 8. I had to update the SET statement to 'SET #previousstate = NULL;' otherwise I get "Illegal mix of collations (utf8mb4_0900_ai_ci,IMPLICIT) and (utf8mb4_unicode_ci,IMPLICIT) for operation '<>'". This error was way above my understanding. I am just a marketing guy working in a small firm. So that is why I set it to NULL.
With that said, after updating the SET statement the result set returns but the if() statement is not working like it did under 5.7. The very first row returned should have the first column of data marked with '*' at the beginning and end, and as the data in the column changes it should mark it too.
So it should look like this:
*brownfdn*
brownfdn
*brownfmi*
brownfmi
But I am getting this:
brownfdn
brownfdn
brownfmi
brownfmi
Do you have any thoughts about what I am doing wrong? I appreciate your help!! Getting to MySql 8 has been a struggle.

I wish to retrieve around 200 million profiles using PDO.
It is a partitioned table, so it does not have a primary key, it's sorted with INNODBs internal primary key.
I need to retrieve the data in internal sort order for performance, so using SORT BY some_id and to continue from there would not work for performance reasons.
Using LIMIT OFFSET would not work at all, OFFSET 100 million or more would take ages, the RAM is by far not enough to take all the terrabyte of table data into cache.
I would need something that fetches a chunk of rows, remembers the internal position and continues with next call.
Update
I was digging a bit and the problem seems familiar, it was solved in Oracle by having ROWID and ROWNUM which refer to the internal id.
It seems we have such an id in innodb as well but it's not queryable ?!
That sounds like a significant disadvantage of mysql for performant query.

So, I have two tables filled with for the most part very similar data, for example, a row in each table may have the same first name, last name, and address, but have a different phone number or email address based on the most recently available data which was updated in a separate excel worksheet (out of my hands, my job is just to merge this data into our latest database which they plan to use from here on out, not the excel sheet). I just need a good way to merge these tables with the same column names without doing it manually (about 24,000+) records.
Here is the Create Table Syntax for both tables:

As you can see, they are basically the same exact tables, I just need to merge them correctly.
Perhaps this is helpful.
update Users
set ADDR = (
select ADDR from UsersUpdated uu
where uu.FULLNME = Users.FULLNME and uu.DOB = Users.DOB
), STNME = (
select STNME from UsersUpdated uu
where uu.FULLNME = Users.FULLNME and uu.DOB = Users.DOB
) ...
;
You can add all the columns to a single update. Depending on the size of the database it might just be as easy to do them individually.
Many platforms allow for a from clause with update that permits a join and a shorter query but it can be problematic. This way you will get errors if any of the subqueries don't return just a single value.
I would modify the Users table to add a UNIQUE key on the fields that should be the same (presumably FSTNME, LSTNME and ADDR from your description but perhaps you might use some other columns e.g. DOB as suggested by #shawnt00), then INSERT the data from UsersUpdated into Users using an ON DUPLICATE KEY UPDATE clause to copy updated data into Users where the user already exists in that table. This query will also work when there are users in UsersUpdated who are not already in Users. So,
ALTER TABLE Users ADD UNIQUE KEY NameAddr (FSTNME, LSTNME, ADDR);
INSERT INTO Users
SELECT * FROM UsersUpdated
ON DUPLICATE KEY UPDATE
FULLNME=VALUES(FULLNME),
LSTNME=VALUES(LSTNME),
FSTNME=VALUKES(FSTNME),
...
LTR=VALUES(LTR),
REGISTERED=VALUES(REGISTERED);
I have google the problem I guess I am not the expert in sql thats why I cant seem to solve it.
I am exporting database from dedicated server and trying to import into google cloud instance apache / sql
I get error like below even I tried all answers in stackoverflow

As additional
I manage to create all tables manual, as much as from my sql knowledge.
I run below commands

But at the end when I try to import from old SQL gives same error of startup.
quite frustrated :(
Try replacing with:
CREATE TABLE islemler ( islemID int(11) NOT NULL, islemKullaniciID int(11) NOT NULL, islemTarih timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, islemBitisTarihi datetime DEFAULT NULL, islemDurum varchar(500) COLLATE utf8_turkish_ci NOT NULL, islemNot varchar(500) COLLATE utf8_turkish_ci NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_turkish_ci MySQL said: Documentation

That runs just fine. However, my Perl script that accesses the database does:
SELECT * FROM glinks_Sales WHERE (TransactionID = ?) ORDER BY Order_Date ASC'
...and it spits out the error:
Illegal mix of collations (utf8mb4_bin,IMPLICIT) and
(utf8_general_ci,COERCIBLE) for operation '='
I'm confused as to where it would be getting utf8_general_ci from? I must be missing something stupid, but I can't see it. Hopefully a fresh pair of eyes will help!
Thanks for any suggestions!
Collation mixes can be a pain. Try to SET collation_connection = 'utf8mb4_bin' before the query:
SET collation_connection = 'utf8mb4_bin';
SELECT * FROM glinks_Sales WHERE (TransactionID = ?) ORDER BY Order_Date ASC';
This sets the collation for the connection, before you run your query.
If that do not work, check other possible collation settings for database, server or connection. You find some hints here: https://stackoverflow.com/a/37298732/1363190
