User Guide

If MapMarker attempts to lock a row that is already locked, MapMarker follows the default behavior
of the database. Usually this means waiting until that row is released. MapMarker does not use any
deadlock detection beyond that provided by the database.

L

You are responsible for maintaining the relationship of the street address and the
latitude/longitude for that address. For example, whenever you change any street address
information, you must re-geocode that record.

If rows are deleted from your table after MapMarker opens the table, MapMarker reports an error
when it tries to geocode that deleted row.

Remote Database Views

You may only geocode views of a remote table when you are doing a table-to-table geocode. See

Writing Geocoding Output to Another Table on page 191

, for more information.

Rollback Segment Limit

Be sure that you set your database rollback segment or temp space to be sufficiently large enough
to accommodate the size of your database.

Supported Unique Index and Primary Key Data Types by Database

The following table identifies the supported data types by RDBMS. A Primary Key must also be
defined for your table.

If MapMarker encounters a mappable table with a spatial type it does not support, an error message
is displayed and the table is not geocoded.

SQL Server) see your product-specific MapMarker Release Notes.
