篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Sybase IQ 12.7 isql命令疑问？相关的知识，希望对你有一定的参考价值。
新公司有用Sybase IQ，主管让安装一个sybase数据库，但是安装完后，isql不能用，不知为何。HQYWAPP-TEST1:sybase > isqlPassword: CT-LIBRARY error: ct_connect(): directory service layer: internal directory control layer error: Requested server name not found.看了网上说要配置interfaces文件，但是具体不知道如何配，目前该文件是空的。环境：AIX5.3
参考技术A 应该是环境没设好：Requested server name not found. 参考技术B isql -Uxxx -Pxxx -Sxxx这些要一起写好才行呀。将查询从 Sybase IQ 转换为 impala

上述查询失败，在 impala 中出现以下错误：
AnalysisException：第 4 行中的语法错误：undefined: where f.gaotag = o.gaotag ^ 遇到：WHERE Expected: DEFAULT, IDENTIFIER CAUSED BY: Exception: Syntax error
我浏览了以下 cloudera 链接： https://www.cloudera.com/documentation/enterprise/5-4-x/topics/impala_subqueries.html 但无法完成这项工作。
我是 Sybase IQ 和 Imapala 的新手。
【问题讨论】：
至少尝试以可读的方式格式化代码 @deb 。 . .简化！尝试在 Impala 中逐个、逐列、逐表地构建查询。 【参考方案1】：你可以尝试用下面的查询替换最后一个查询并尝试运行它 -

【讨论】：
您能否运行每个单独的查询并告诉我们哪个特定查询有问题.. 取 union all 的每个部分并尝试获取结果 问题似乎出在内部联接或 where 子句上，其余的查询在单独运行时运行良好。 问题是我添加的连接语法，你现在可以再检查一下吗以上是关于Sybase IQ 12.7 isql命令疑问？的主要内容，如果未能解决你的问题，请参考以下文章
