hive 建表语句 解析为 List<SQLStatement>

可以使用阿里巴巴的开源项目Druid来解析Hive建表语句，具体代码如下：

import com.alibaba.druid.sql.SQLUtils;
import com.alibaba.druid.sql.ast.SQLStatement;
import com.alibaba.druid.sql.ast.statement.SQLCreateTableStatement;
import com.alibaba.druid.sql.dialect.hive.parser.HiveStatementParser;

import java.util.List;

public class HiveDDLParser {

    public static List<SQLStatement> parse(String ddl) {
        HiveStatementParser parser = new HiveStatementParser(ddl);
        List<SQLStatement> statementList = parser.parseStatementList();
        return statementList;
    }

    public static void main(String[] args) {
        String ddl = "CREATE TABLE test_table (\n" +
                "  col1 string,\n" +
                "  col2 int,\n" +
                "  col3 double\n" +
                ") ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE;";
        List<SQLStatement> statementList = HiveDDLParser.parse(ddl);
        for (SQLStatement statement : statementList) {
            if (statement instanceof SQLCreateTableStatement) {
                SQLCreateTableStatement createTableStatement = (SQLCreateTableStatement) statement;
                System.out.println(createTableStatement.getTableSource().getExpr().toString());
            }
        }
    }
}

其中，`HiveStatementParser`是Druid提供的Hive语法解析器，`parseStatementList()`方法可以将Hive建表语句解析为多个`SQLStatement`对象，然后可以通过`instanceof`判断其具体类型，再进行相关操作。以上代码演示了如何解析Hive建表语句，并获取表名。
