<< Click to display table of contents >> TRVReportTableCellData.DataQuery |
A string containing a data query.
property DataQuery: TRVUnicodeString;
An example of a DataQuery is a SQL query, like 'SELECT * FROM MyTable'.
TRVReportGenerator creates a query processor for this data query. This query processor returns data for this query, and the report generator replicates a content of this cell as many times as many records in the returned data. Then the report generator processes these replicated contents, replacing data fields in them accordingly.
This string may contain field codes that will be replaced on report generation before creating a query processor.
A direct assignment to this property cannot be undone by the user. Use Table.SetCellDataQuery to assign a new value to this property as an editing operation.
Default value:
'' (empty string)
