Key-ins for Joins

Joins can be created by using key-ins as described:

Key-in	Description
MAP JOIN ADD feature1.property1=feature2.property2	Adds a join between feature 1 and feature 2. Note that the feature and property names are case-sensitive. Example: map join connect Hydrants.WmainID=Watermains.WmainID
MAP JOIN CLEAR	Removes all joins.
MAP JOIN CONNECT <filename>	Establishes a connection to the specified file such as a SHP or VRT file. This key-in is typically followed by the MAP JOIN ADD key-in. Example: map join connect d:\shp\watermains.shp Example: map join connect d:\imports\watermains.vrt
MAP JOIN REMOVE feature1.property1=feature2.property2	Removes the specified join. The key-in should respect f1.p1=f2.p2 format. Note that the feature and property names are case-sensitive. In addition, f1 must always be specific, while wild cards can be used for other parameters. Example: map join remove Hydrants.WmainID=Watermains.WmainID Example: map join remove Hydrants.=.*
MAP JOIN SHOW	Opens the Defines Joins dialog and selects the left and right side features as the first feature found.
