Table probe icon

Table Probe

The Table Probe icon indicates that data from the table is needed to be processed and selected for this query. The table is probed using a key derived from the ordinal number or relative record number associated with each row in the table. The ordinal number is used to calculate what pages of data need to be retrieved and brought into main memory in order to satisfy this probe request. The ordinal number used for the probe operation was provided by another data access method previously processed for this query.
