Question

我有一个与1个输入参数配合使用的SQL查询例如

mydf1=dbGetQuery(con2, paste0("select month from incoming where to_char(TO_TIMESTAMP(vessel_servertimestamp, 'YYYY-MM-DD HH24:MI:SS'), 'MON') in  '",input$dataset1,"' 
group by  month "))

如何构造一个SQL查询以传递多个输入参数？下面是selectInput ..

output$dataset1 =renderUI({
      selectInput("dataset1", "Choose month:", 
                  choices  = as.list(c("JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP","OCT","NOV","DEC")),
                  multiple = TRUE)
    })

Answer 1

您需要将输入$ dataset的sql部分更改为

in (", paste0("'", input$dataset1, "'", collapse = ","), ") group_by month"

传递多个输入sql查询闪亮
