rsqlite_send_query(conn@ptr, statements) 中的错误：“.”附近：语法错误

Question

q1<- dbGetQuery(conn,
                "SELECT UNIQUELETTERCODE_y , 
                        COMPLETION.MODE, 
                        COMPLETED.BY, 
                        Current.Status, 
                        Completed.by.which.group 
                    FROM Daily_Returns 
                      WHERE AgentName IS NULL AND
                            CASEID IS NULL AND
                            Completed.by.which.group = OUTBOUND AND
                            Current.Status = Completed AND
                            (COMPLETED.BY = CALL OR
                            COMPLETED.BY = CISCO OR
                            COMPLETED.BY = MOBILE) AND
                            COMPLETION.MODE =CALL 
                        GROUP BY UNIQUELETTERCODE_y
                ")

使用上面的代码一直提示这个Error: Error in rsqlite_send_query(conn@ptr, statements) : close ".": 语法错误，知道如何解决这个问题吗？

Answer 1

您的查询中有拼写错误。这是一个固定的查询：

"
SELECT DISTINCT UNIQUELETTERCODE_y, 
                                 COMPLETION_MODE, 
                                 COMPLETED_BY, 
                                 Current_Status, 
                                 Completed_by_which_group 
                  FROM Daily_Returns 
                  WHERE AgentName IS NULL AND
                        CASEID IS NULL AND
                        Completed_by_which_group = 'OUTBOUND' AND
                        Current_Status = 'Completed' AND
                        (COMPLETED_BY = 'CALL' OR
                         COMPLETED_BY = 'CISCO' OR
                         COMPLETED_BY = 'MOBILE') AND
                        COMPLETION_MODE = 'CALL'
"

1. 您必须为每个 where 参数添加

   '

   ，例如

   'OUTBOUND'

   、

   'Completed'

   等
2. 防止在列名称上使用

   .

   。在 SQL 中，句点 (.) 通常用于限定表名或列名，并且列名不直接支持点表示法。在大多数情况下，列名称不能包含句点。
