问题 Currently I receive a daily file of around 750k rows and each row has a 3 character identifier at the start. For each identifier, the number of columns can change but are specific to the identifier (e.g. SRH will always have 6 columns, AAA will always have 10 and so on). I would like to be able to automate this file into an SQL table through SSIS. This solution is currently built in MSACCESS using VBA just looping through recordsets using a CASE statement, it then writes a record to the

问题 I am working with a big table (~100.000.000 rows) in SQL Server 2008. Frequently, I need to add and remove batches of ~30.000.000 rows to and from this table. Currently, before loading a large batch into the table, I disable indexes, I insert the data, then I rebuild the index. I have measured this to be the fastest approach. Since recently, I am considering implementing table partitioning on this table to increase speed. I will partition the table according to my batches. My question, will
