I am trying to load a file using the SQL Server Import Data function

  • 0

I am trying to load a file using the SQL Server Import Data function – appending rows to an existing table.

my existing table is created like this:

CREATE TABLE [dbo].[load](
    [Long] [varchar](50) NULL,
    [Lat] [varchar](50) NULL,
    [Geog]  AS ([geography]::STGeomFromText(((('POINT('+[Long])+' ')+[Lat])+')',(4326)))
)

however when the load tries to execute i see the following error messages. I believe the issue is around the computed column ‘Geog’ as the data loads fine when i take this out of the table definition.

    So it would appear that having a computed column which contains the geography type in the definition is not supported (i tried with other types including the POINT type and it worked fine). This could be down to the lack of support that SSIS has for the spatial data types or down to the way that SQL Server processes the computed column during a batch insert.

    Either way i had to create a solution to my issue and came up with the following work around.

    In my SSIS package i start by removing the computed column which is causing the issues.
    Then i run the data load process
    Then i re-add the computed column to the table using the ALTER statement.

    This works fine for the time being, although it could cause some issues with off-line data during a run-time scenario. however, it should be simple enough to address this issue.

    This did mean that i had to create a more complex SSIS package than just using the simple ‘Import data’ wizard provided by SQL Server, and i still feel a little frustrated that i dont know the actual cause of my issue. I just found a way to work around it and move on. I would still appreciate if someone could point out why i was seeing this failure.
