SQL: MakeValid() 不适用于 SqlGeography 类型
SQL: MakeValid() not working on type SqlGeography
我正在尝试让 SQL MakeValid() 函数处理地理类型，但出现以下错误：
Could not find method 'MakeValid' for type 'Microsoft.SqlServer.Types.SqlGeography' in assembly 'Microsoft.SqlServer.Types'

感谢任何帮助
如前所述，对于SQL SERVER 2008
这适用于 SQL Server 2008。将形状加载为几何图形后，使用 MakeValid() 更正它，然后重新加载到地理中。
DECLARE @gt NVARCHAR(MAX)
DECLARE @gm GEOMETRY
