阅读更多关于 Copying large amounts of data into a SQL CE database

问题 If I have a large amount of data in memory, what is the best way to copy it into a SQL CE table? The current technology stack is C#, ADO.net, and SQL CE. My initial idea was to do one INSERT statement for each row of data, but this is time-consuming. Is there an easier way? 回答1: The first thing that popped into my head was to do a sync/merge with a desktop or server database, though that doesn't sound like it really fits your needs. So here is my second thought: BULK INSERT table_name FROM

阅读更多关于 Why is BCP so fast?

问题 So BCP for inserting data into a SQL Server DB is very very fast. What is is doing that makes it so fast? 回答1: In SQL Server, BCP input is logged very differently than traditional insert statements. How SQL decides to handle things depends on a number of factors and some are things most developers never even consider like what recovery model the database is set to use. bcp uses the same facility as BULK INSERT and the SqlBulkCopy classes.

Does sybase 15 support the bcp api in java?

阅读更多关于 Does sybase 15 support the bcp api in java?

A long time ago I figured out that bcp is just a little C program that calls the special bit of the sybase client api to do mass data moving into the database. It lies cheats and steals and skips check constraints all in the name of speed. Great, I'm all for it. In sybase 12 I noticed that the api was exposed in the C client library, but not the java one. I've been looking but I haven't found anything that says they've yet implemented it in the sybase 15 java client library. Does anybody know if this is available or not in sybase 15? I disagree with your comments on Java using a BCP api.
