## 1.格式：
```
CREATE TABLE tableName(
    colName colType,
    ...
    colNameX colType,
    primary key (colName)
 )WITH(
    type ='sqlserver',
    url ='jdbcUrl',
    userName ='userName',
    password ='pwd',
    tableName ='tableName',
    parallelism ='parllNum'
 );

```

## 2.支持版本

|----|---|
| tableName| sqlserver表名称|
| colName | 列名称|
| colType | 列类型 [colType支持的类型](../colType.md)|
| primary key | updateMode为UPSERT时，需要指定的主键信息|

CREATE TABLE source1 (

    zookeeperQuorum ='172.16.8.107:2181/kafka',
    offsetReset ='latest',
    topic ='mqTest03',

    topicIsPattern ='false'
 );


CREATE TABLE source2(
    id int,
    address VARCHAR
)WITH(

CREATE TABLE MyResult(
    id int,
    name VARCHAR,
    address VARCHAR,
    primary key (id)
)WITH(
    type='sqlserver',
    url='jdbc:jtds:sqlserver://172.16.8.149:1433;DatabaseName=DTstack',
    userName='sa',
    password='Dtstack2018',
    tableName='user',
    schema = 'aaa',
    updateMode = 'upsert',
    batchSize = '1'
);

insert into MyResult
select 
	s1.id,
	s1.name,
	s2.address
from 
	source1 s1
left join
	source2 s2
on 	
	s1.id = s2.id

 ```
 
数据结果：

向Topic mqTest03 发送数据  {"name":"maqi","id":1001}  插入 (1001,"maqi",null)

向Topic mqTest04 发送数据  {"address":"hz","id":1001} 删除 (1001,"maqi",null) 插入  (1001,"maqi","hz")
