Add NOLOCK syntax into Power Query

[Anonymous]

Hi,

We are connecting our dataset from SQL Server to Power BI and we want to include the NOLOCK syntax to avoid the lockage of DB during the scheduled data refresh time under Import mode.

Anyone can suggest how to put the syntax in place to make it work?

Already tried the following syntax in the Advance Editor but having error message in the below screen shot, tried many different ways to debug this but seems not working......anyone can suggest how to fix this?

=======================

let
 Source = Sql.Database("xxx.com", "XYZCompany"),
dbo_OrderedItemSummary = Sql.Database("xxx.com", "XYZCompany",[Query="SELECT * FROM dbo.OrdereditemSummaryPermissionGroup (NOLOCK)"]),

#"Duplicated Column" = Table.DuplicateColumn(dbo_OrderedItemSummaryPermissionGroup, "PermissionGroup", "PermissionGroup - Copy"),
#"Renamed Columns" = Table.RenameColumns(#"Duplicated Column",{{"PermissionGroup - Copy", "UserId"}}),
#"Expanded UserId" = Table.ExpandRecordColumn(#"Renamed Columns", "UserId", {"UserPermissionGroup"}, {"UserId.UserPermissionGroup"}),
#"Expanded UserId.UserPermissionGroup" = Table.ExpandTableColumn(#"Expanded UserId", "UserId.UserPermissionGroup", {"UserId"}, {"UserId.UserPermissionGroup.UserId"}),
#"Renamed Columns1" = Table.RenameColumns(#"Expanded UserId.UserPermissionGroup",{{"UserId.UserPermissionGroup.UserId", "UserId"}})
in
#"Renamed Columns1"

=======================

Here is how the table OrderedItemSummaryPermissionGroup looks like from DB.

Best regards,

Hi it seems using NOLOCK clause in direct query makes you to use a 'native query' mode that does not support query folding (needed for incremental refresh). It seems better option is to create a view from a table and add NOLOCK clause in there .

Hi @Anonymous 

You can always create views that include (NOLOCK) and use these views in Power Query

Hi @Mariusz 

Can I simply include NOLOCK in the Advance Editor in Power Query instead of creating new views?

Thanks.

Hi, did you figure out the syntax for adding NOLOCK to the Advanced Editor in Power Query?
