Enter Data in SQL based on user input

shiny
1

I want to insert data in SQL Table based on user input. I need to add radiobutton (or checkbox) in each row of a column (let's say 'FLAG'). Value will be flagged 1 when user selects checkbox of a row. The whole row against the checkbox should be entered into SQL table.

I am able to update check box in each row. See the update code below -

library(shiny)
library(DT)

# FETCH DATA
cn = odbcDriverConnect(connection='driver={SQL SERVER}; Server=xxx; database=xxx;
                       port=xxxx; uid=xxx; pwd=xxxx')
mydata = sqlQuery(cn,"SELECT X1, X2,X3,X4 FROM DBO.Table1")
mydata$id = 1:nrow(mydata)

runApp(
  list(ui = pageWithSidebar(
    headerPanel('Sample FWA Table'),
    sidebarPanel(
      checkboxGroupInput('show_vars', 'Columns to show:', names(mydata),
                         selected = names(mydata))
    ),
    mainPanel(
      DT::dataTableOutput("mytable")
    )
  )
  , server = function(input, output, session) {
    rowSelect <- reactive({
      paste(sort(unique(input[["rows"]])),sep=',')
    })

    output$mytable = DT::renderDataTable({

      addCheckboxButtons <- paste0('<input type="checkbox" name="row', mydata$id, '" value="', mydata$id, '">',"")
      DT::datatable(cbind(Flag=addCheckboxButtons, mydata[, input$show_vars, drop=FALSE]),filter="top", 
                    selection="multiple", options = list(orderClasses = TRUE, 
                                                         lengthMenu = c(5, 10, 25, 50), pageLength = 5, 
                                                         callback = JS("function(table) {
      table.on('change.dt', 'tr td input:checkbox', function() {
          setTimeout(function () {
          Shiny.onInputChange('rows', $(this).add('tr td input:checkbox:checked').parent().siblings(':last-child').map(function() {
          return $(this).text();
          }).get())
          }, 10); 
          });
          }")),escape = FALSE,

      )
    } 
    )
  }
  )
)

I want to know how to INSERT INTO in SQL based on checkbox selection.
