ReplaceData(proxy1, long_sepal, resetPaging =ĭbWriteTable(con, "data", data. This extension to SQL allows an UPDATE statement to be driven by other tables. #necessary code to replace data once edited To perform an UPDATE with a join in SQLite, you can use the UPDATE FROM extension. Output$table2 <- renderDT(short_sepal, options = For number 2 a better method (if you are using an old version of SQLite3 that does not have UPDATE FROM) would be: update MyTable as dst set (vala, valb, valc) (select vala, valb, valc from MyTable where objectid dst. Output$table1 <- renderDT(long_sepal, options = Syntax Following is the syntax of the UPDATE statement in SQLite UPDATE tablename SET column1 value1, column2 value2. To update specific rows, you need to use the WHERE clause along with it. # Define server logic required for editable tables You can update the values of existing records in SQLite using the UPDATE statement. Ui <- dashboardPage(title = 'Iris Dashboard', ,DT::dataTableOutput(outputId = "table2", height = #sidebar with "Write to DB" reactive buttonĭiv(style="display:inline-block width:32% text-align:Ĭenter ",actionButton("action", label = "Write to Header <- dashboardHeader(title="Iris Dashboard") I would like to update a value in the master table with the value in the scheduled table if I run a query some time after due has occurred. I have an application using SQLite with two tables a master table and a scheduled table. Short_sepal <- filter(data, sepal_length<5.5) Update values in one table from data in another. I included a reprex using Iris data below. Should I be able to see the updates to the dataframe in the Global environment as they are made?.When the editable function works right, is it editing long_sepal or data?.My questions (beyond "How can this work?"): The UI side behaves as expected, but when I edit a page and hit my Write to Table button, then reload or close out of the app, it does not look like the DT or database has updated. My plan is to use the DT and DBI packages to edit specific values, then push the updates back to the SQLite table by dropping the old one and writing the new one in its place (haven't coded the drop table yet, but will go into button actions). I have created a for an editable SQLite membership database dashboard.
