Is their an issue with importing Excel files with null rows into SQLServer 2005 tables -


i using openrowset() function import excel file temporary sqlserver 2005 table.

it works fine in cases. if first 10 rows of excel file null, remaining non-null rows imported null.

has encountered issue previously? thoughts on how overcome it?

this caused how oledb driver determines datatypes in excel. default scans first 8 rows determine datatype of fields.

  • you used able set "maxscanrows" in connection string configure rows scan in worksheet. setting unfortunately not work anymore since jet 4.0. way force set th registry key [hklm\software\microsoft\jet\4.0\engines\excel\typeguessrows]. possible values 1-16 or 0 scan whole file.
  • there imex setting (which means importmixedtypes) when set 1 means "importmixedtypes=text". solves lot of issues driver determines datatype based on amount of values in type finds.
