I tried flink 1.16.0 with the same env,now in sql-client can swiftly get the
exception："[ERROR] Could not execute SQL statement. Reason:
java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check
the manual that corresponds to your MySQL server version for the right syntax
to use near 'FROM `users1013a`' at line 1" ,then the collect job just failed
and never retry

> Hi, I use flink sql to make kafka records to mysql.
> so I create these 2 tables in flink sql,here is the mysql ,and I created the
> table in mysql before I did the insert action in flink sql.
> CREATE TABLE mysql_MyUserTable (
> id STRING,
> name STRING,
> age STRING,
> status STRING,
> PRIMARY KEY (id) NOT ENFORCED
> ) WITH (
> 'connector' = 'jdbc',
> 'url' = 'jdbc:mysql://10.19.29.170:3306/fromflink152',
> 'table-name' = 'users',
> 'username' = 'root',
> 'password' = '******'
> );
> In mysql, I created database "fromflink152" then created the table like this
> way
> CREATE TABLE `users` (
> `id` varchar(64) NOT NULL DEFAULT '',
> `name` varchar(255) DEFAULT NULL,
> `age` varchar(255) DEFAULT NULL,
> `status` varchar(255) DEFAULT NULL,
> PRIMARY KEY (`id`)
> )
> After executed insert sql,I found 'select * from mysql_MyUserTable' can get
> correct result,but ’select count(\*) from mysql_MyUserTable‘ or ’select
> count(id) from mysql_MyUserTable‘ ,the collect job in flink app keep
> restarting again and again.The exception is:
> !image-2022-10-10-15-31-34-341.png!
> So I wonder which config that I missed about the table in flink or mysql side
> :(
