我有一个文本格式配置单元表，例如：
CREATE EXTERNAL TABLE op_log (
time string, debug string,app_id string,app_version string, ...more fields)
PARTITIONED BY (dt string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'
STORED AS TEXTFILE;
现在我创建一个具有相同字段的兽人格式表，例如
CREATE TABLE op_log_orc (
time string, debug string,app_id string,app_version string, ...more fields)
PARTITIONED BY (dt string)
STORED AS ORC tblproperties ("orc.compress" = "SNAPPY");
op_log当我从to复制时op_log_orc，出现以下错误：
hive> insert into op_log_orc PARTITION(dt='2016-08-09') select * from op_log where dt='2016-08-09';
FAILED: SemanticException [Error 10044]: Line 1:12 Cannot insert into target table because column number/types are different ''2016-08-09'': Table insclause-0 has 62 columns, but query has 63 columns.
