Errors when Transferring MS Access data to SQL Server 2014 Express

SQL Server Administration
1

My experience with SQL is limited and was hoping someone could give me some advice. Needing some suggestions on how to combat the below errors in order to have a successful transfer of an Access database file onto SQL 2014 Express server. I have been utilising the SQL Server Import and Export Wizard to complete this which has returned several errors. A copy of the errors are shown below. Any advice would be greatly appreciated.

  • Copying to [dbo].[Tbl_*****] (Error)

Best to first stage your data in a staging table with all the columns defined as nvarchar(max) and retry then from staging to final destination table

Thanks yosiasz, never used a staging table before but will look into this as an option.

Any other suggestions anyone ?

The problem is that you have something defined in your Access database that SQL Server is not able to convert to a valid SQL Server data type. This could be something as simple as the default string length being assigned - where SQL Server is defining that as 50 characters but Access has more than 50 characters in the source column.

It could also be a string column in Access that contains only numbers - and SQL Server is attempting to convert that to an integer but the string value is larger than allowed for the integer data type.

The best way to handle this is to build the table in SQL Server first - verifying the columns data types are correct, then importing the data from Access into the existing table.
