Table-Valued Parameter without using a stored procedure

阅读更多关于 Table-Valued Parameter without using a stored procedure

问题 It seems all I can find online are examples of table-valued parameters that require using a stored procedure. I recall doing this in the past without the stored procedure. Is that possible? This code keeps throwing an error about the type not being specified. SqlCommand cmd = new SqlCommand(@" UPDATE t1 SET t1.ScheduledStartUTC = t2.ScheduledStartUTC FROM ScheduleTickets AS t1 INNER JOIN @SetScheduledStart AS t2 ON t1.ScheduleId = t2.ScheduleId AND t1.PatchSessionId = t2.PatchSessionId ", c);

I have an application that uses SqlBulkCopy to move data into a set of tables. It has transpired recently that users that are using SQL2016 are reporting problems with their harddrives being filled with very large databases (that should not be that large). This problem does not occur in SQL2014. Upon inspection it appears that running TableDataSizes.sql (script attached) showed large amounts of space in UnusedSpaceKB. I would like to know if a) There is some bug in SQLServer 2016 or if our use of SQLBulkCopy has "clashed" with a new feature. I note that there has been some changes to Page
