Msg 7403, Level 16, State 1, Line 1
The OLE DB provider " Microsoft.ACE.OLEDB.12.0" has not been registered.

But when the File Path is static i.e., file path ,sheet name etc are fixed..

select *from OPENDATASOURCE('Microsoft.ACE.OLEDB.12.0','Excel 12.0;IMEX=1;Hdr=Yes;
database=E:\GCS Appl\GCS\Data\excel file\Anugul\Anugul-Anugul.xlsx')...[code$]

It works
