CheckLastOnOpen

Flag indicating whether a get-last should be performed on an open in order for fetchNext to detect that we are on the last row. This is necessary to make the QueryPosition attribute reliable.

Data type: LOGICAL

Notes:

Read and Write.
The DataColumsByTable property that stores in different tables delimited by CHR(1) instead of a comma in order to identify which columns are from which table in the event of a join. For example, if the query is a join of customer and order and the Name field from customer and the OrderNum and OrderData field from Order are selected, then the property value becomes equal to Name<CHR(1)>OrderNum,OrderDate.
This function replaces CHR(1) with "," returns just a comma-delimited list.
