Question

I am using an SQL Server that is connected with

• Service Type: Database Engine
• Server name: cloudquotedev.database.windows.net
• Authentication: SQL Server Auth with given User name and Password

When I run following SQL statement I am getting an error:

insert into attachments 
values (1, 'Holiday List 2022', 'PDF',
        (select * 
         from Openrowset(BULK 'C:\temp1\export_holiday_list.pdf', SINGLE_BLOB) as pdf))

Error:

Msg 4861, Level 16, State 1, Line 1
