我正在使用 IBM BigInsights 4.1.0 版。

我使用以下命令从 teradata 中提取数据。

LOAD HADOOP USING JDBC CONNECTION URL 'jdbc:teradata://<<ip_address>>/database=<<db_name>>' WITH PARAMETERS ('user' = '<<user_name>>','password'='<<password>>') FROM TABLE <<table_name>> COLUMNS (<<COL1, COL2, COL3, .... COLN>>) SPLIT COLUMN <<COLM>> INTO TABLE <<Target_bigsql_schema>>.<<target_bigsql_table>> APPEND WITH LOAD PROPERTIES ('tdch.enable'='true');

执行上述命令时出现的错误如下

有没有可能的解决方案？

TDCH 不支持 Teradata 的本机 CHAR 和 VARCHAR。
