解决方法
此脚本将显示具有引用要删除的行的行的所有表：
declare @RowId int = 1
declare @TableName sysname = 'ParentTable'
declare @Command varchar(max)
select @Command = isnull(@Command + ' union all ','') + 'select ''' + object_name(parent_object_id) +
''' where exists(select * from ' + object_name(parent_object_id) + ' where ' + col.name+ ' = ' + cast(@RowId as varchar) + ')'
from sys.foreign_key_columns fkc
join sys.columns col on
fkc.parent_object_id = col.object_id and fkc.parent_column_id = col.column_id
where object_name(referenced_object_id) = @TableName
execute (@Command)
假设外键不复合.
