insert into select语句【可以复制geometry字段】
sql server自带的导入导出功能可以导普通的属性表：
但是，如果你要复制的表中存在geometry字段，如果用sql server自带的导入导出表的功能将无法导入带geometry字段的表。可以用insert into select语句将一个表中的数据复制到另一表中：
两个表在同一中：
insert into mapping_geodata_boundary_code(code, name, description, type, parent_code, boundary, center_point, boundary_hole, boundary_hole_id, is_thematicmap, supportfile_code, boundary_all)
select code, name, description, type, parent_code, boundary, center_point, boundary_hole, boundary_hole_id, is_thematicmap, supportfile_code, boundary_all from mapping_geodata_boundary
两个表在不同数据库中（ openquery)：
insert mapping_geodata_boundary
(code, name, description, type, parent_code, boundary, center_point, boundary_hole, boundary_hole_id, is_thematicmap)
select code, name, description, type, parent_code, boundary, center_point, boundary_hole, boundary_hole_id, is_thematicmap from openquery([10.10.1.31],'select code, name, description, type, parent_code, boundary, center_point, boundary_hole, boundary_hole_id, is_thematicmap from epro30.dbo.mapping_geodata_boundary')
