IsNoRecord

IsNoRecord()

This function tells whether a report has returned a record or not. If the report has no value returned, the function will return True, otherwise False.

Note: A formula which calls this function cannot be applied to queries, and this formula only takes effect when laying out this report which contains it.

Example

When using this function, you should refer to a DBField to identify whether this formula is a record level formula so that it can be calculated when fetching the record. For example,

@"Customers_Customer ID";
if(IsNoRecord())
return "There is no data"
else
return "Total number of records="+@"Count_Customer Name5"

In this example, if no data returned, a tip "There is no data" will be displayed. If data is returned, the Total number of records will be displayed.
