??CREATE TABLE user_account( uid BIGINT, system_unique_id STRING, name STRING,
account STRING, passwd STRING, salt STRING, type INT, avatar STRING, source
STRING, ksjk_existing TINYINT, created_at INT, updated_at INT, deleted_at INT,
PRIMARY KEY (uid) NOT ENFORCED ) WITH ( 'connector' = 'jdbc', 'url' =
'jdbc:mysql://10.10.15.17:3306/haohuan_db', 'table-name' = 'user_account',
'driver' = 'com.mysql.jdbc.Driver', 'username' = 'canal', 'password' =
'lOCHvm86gUKSXmLVb3qg' );??
This is my SQL statement and connection information, the information is
correct, tested, and then I will execute the query uid field, because he is
biginteger type, and then it will send an error:
