so if the source table doesn't have either pk or unique index.. what will be syntax to enable the table?

is it

USE Db

GO

EXEC sys.sp_cdc_enable_table

@source_schema = N'DBO',

@source_name = N'tbl_Name',

@role_name = NULL;

GO

Or we need to specify some value for @supports_net_changes

USE Db

GO

EXEC sys.sp_cdc_enable_table

@source_schema = N'DBO',

@source_name = N'tbl_Name',

@role_name = NULL

@supports_net_changes = ??;

GO

Am attempting CDC for the first time.. please point out if am missing something.

TIA
