Re: Problem in reading From JDBC SOURCE
Hi
Below is the script I used to create table in Mysql
CREATE TABLE `sample` (
`id` varchar(45) NOT NULL,
`a` decimal(10,3) DEFAULT NULL,
`b` decimal(10,3) DEFAULT NULL,
`c` decimal(10,3) DEFAULT NULL,
`d` decimal(10,3) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
Table data
Id- 1
a- 0.002
b- 2.250
c- 0.789
d- 0.558

Re: Problem in reading From JDBC SOURCE
Vishnu,
I think is hard to troubleshoot things without the proper context. In
your case, could you please share an example of the rows contained in
the table `sample`? As well as its DDL?

Re: Problem in reading From JDBC SOURCE
I go through that documentation
Where it described like DECIMAL is not supported in MySQL like this .
And also no example for MySQL so is there any other sample with MySQL

Problem in reading From JDBC SOURCE
Hi Guys,
I am having some problem while reading from MySQL using JDBC source and
received like below
Anyone know what is the reason and how to solve this ?
"a": "Aote",
"b": "AmrU",
"c": "AceM",
"d": "Aote",
Instead of
"a": 0.002,
"b": 0.465,
"c": 0.545,
"d": 0.100
It's my configuration
{
"name": "sample",
"config": {
"connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector",
"connection.url": "jdbc:mysql://localhost:3306/sample",
"connection.user": "",
"connection.password": "xxx",
"topic.prefix": "dample-",
"poll.interval.ms": 360,
"table.whitelist": "sample",
"schemas.enable": "false",
"mode": "bulk",
"value.converter.schemas.enable": "false",
"numeric.mapping": "best_fit",
"value.converter": "org.apache.kafka.connect.json.JsonConverter",
"transforms": "createKey,extractInt",

}
}
