步骤一:导入ClickHouse JDBC驱动 首先,我们需要在项目中导入ClickHouse JDBC驱动。你可以在Maven项目中添加以下依赖: <dependency><groupId>ru.yandex.clickhouse</groupId><artifactId>clickhouse-jdbc</artifactId><version>0.3.1</version></dependency> 1. 2. 3. 4. 5. 步骤二:创建数据库连接 接下来,我们需要...
接下来,可以通过以下代码段来连接ClickHouse集群并执行查询: importjava.sql.Connection;importjava.sql.DriverManager;importjava.sql.ResultSet;importjava.sql.Statement;publicclassClickHouseExample{publicstaticvoidmain(String[]args){Stringurl="jdbc:clickhouse://localhost:8123/default";Stringuser="default";Stringpa...
<artifactId>clickhouse-jdbc</artifactId> <version>0.3.1</version> </dependency> </dependencies> 然后,您可以使用以下代码连接到ClickHouse集群的多个IP地址: import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; pu...
