I know it's tricky, but that a very generic way of parameterizing KNIME workflows which get even more powerful when embedded into loops. The node will then replace this setting always with the variable value during execution time. The MDB/ACCDB Viewer comes with advanced technique integrated into it that allows previewing corrupt database too. Last step, configure the node as usual in the dialog and switch over to the Flow Variables tab, in the URL-property combobox choose the variable that you have just created. MS Access viewer is a powerful free tool to repair corrupt ACCDB/MDB files and preview the original records present within Microsoft Access files. In order to get the home directory, one could use the Extract System Properties node and filter by using the Row Filter then you need to append the database file name as well as the protocol, for example with the String Manipulator, translate the single row into a variable using the TableRow to Variable node and inject this into the Database Reader node (enable flow variables ports from the node context menu). Filter on specific column Data (With many options) Sort table data by column View Row Detail Form support Big database (Tested on 350MB 2,5 million Rows). I see two possibilities to have such generic workflow: either you create a ODBC/JDBC system resource and link to the database the URL in the KNIME Database Reader is then simply jdbc:obdc:yourID or you make use of KNIME's flow variable concept that allows to inject parameters into any node. Features Open All ms Access database Version open ACCDB database or MDB database.
