I have completed the variable declaration, and I don't think there's anything missing.
What should I fix?

Mysql 5.7 Issue in declare handler for duplicate key

We are facing an issue in declaring handlers in MYSQL 5.7 stored procedure.
Using the documentation present in https://dev.mysql.com/doc/refman/5.7/en/get-diagnostics.html, I'm trying to create handler in my stored procedure to do the following:
If a duplicate key appears, log it and move on insert good row.
End of the stored proc, get me all the error and success rows inserted.
As you can see below, we don't have primary key for table, however have the unique key constraint.
Input
CALL userTableInsert('{"userid":100, "username":"Hello"}, {"userid":102, "username":"World"}, {"userid":102, "username":"World"}', #got_dups)
Expected Output
100:Hello should get inserted and 102:World should get errored out and status needs to be corrected depicted in the output of the stored procedure.

MySQL Regex pattern for ***.leave this.*** doesnt work

What pattern to use to leave the characters between dots in string
"12395.KS_TH014.001239" so what would be left only "KS_TH014", if its dynamical var.
I tried pattern ".\K.*?(?=.)" but it doesnt work in mysql (mariadb 10.0.10 server)

There are no regex groups up and including mysql-5.7. However one can use UDF(user defined function) to achieve similar behavior:
SELECT REGEX_REPLACE(REGEX_CAPTURE_LEFTMOST('12395.KS_TH014.001239', '[[.period.]].*[[.period.]]'), '[[.period.]]', '');
The function below replaces the leftmost regex in a string:
DELIMITER $$
CREATE FUNCTION REGEX_REPLACE(var_original VARCHAR(1000), var_pattern VARCHAR(1000),
var_replacement VARCHAR(1000)) RETURNS VARCHAR(1000)

DECLARE var_replaced VARCHAR(1000) DEFAULT var_original;
DECLARE var_leftmost_match VARCHAR(1000) DEFAULT

Could it be a false error as it can not compile as you have no "END" to the overall procedure?. You close out your loops and block, but not the procedure.
