Database Table - Connect the HTML with a Column of a Database Table.
Expression - Fill the HTML with the result of an Expression.
After choosing the source of the data, you will need to fill in a data set in the fields below. Thus:
Database Table
There are two ways of connecting your HTML to a Database Table therefore presenting the value of a specific Column.
1 – You can do it by simply defining the "Table" and "Column" properties and then using the "First Record"/"Last Record"/"Next Record"/"Previous Record" and "Refresh"/"Refresh Plane"/"Refresh Control" Actions.
2 – The other way is to implicitly define a "Select" statement. To do so, you have to define the "Table", "Column", "Where the value of" and "It’s equal to" properties then use the Refresh", "Refresh Plane" or "Refresh Control" Action. This way you are telling Kalipso to perform a "Select" statement like this:
Select <Column> from <Table> where <Where the value of> = <It’s equal to>
Target (store the control's Value in) If this property is set, when Kalipso tries to use the value of this HTML for executing one of the above Actions, it checks if the value is non empty; if it’s not, Kalipso will produce an automatic error message.
Global Variable – Global Variable where to store the HTML value;
Local Variable – Local Variable where to store the HTML value;
Database
