以下HQL在HDP 2.6.1＆amp; Hive 1.2.1000。它是直线问题还是Hive版本？
Error: Error while compiling statement: FAILED: ParseException line 1:133 cannot recognize input near 'KEY' '(' 'string_id' in column type (state=42000,code=40000)
错误
ALTER TABLE `aravind_stg_platform_nw_northwind_nwdb.strings` ADD CONSTRAINT string_id_PK PRIMARY KEY (`string_id`);
甚至ALTER命令也会出现相同的错误
