问题 I have a web-service that calls a stored procedure from a MS-SQL2005 DB. My Web-Service was timing out on a call to one of the stored procedures I have (this has been in production for a couple of months with no timeouts), so I tried running the query in Query Analyzer which also timed out. I decided to drop and recreate the stored procedure with no changes to the code and it started performing again.. Questions: Would this typically be an error in the TSQL of my Stored Procedure? -Or- Has

问题 I have a table which has hierarchy in it. Lets start with Id = 5 ; this is the child. (a given start parameter - from user) Algorithm: give me the first value which you have encountered for id = 5 if you haven't found value for id = 5 , go to its parent and give me his id if this parent also doesn't have a value - go to its parent ... etc (until parent has no parent - parentId = 0 ) p.s. the result here should be 7. if 7 value was empty so : 9 end if 9 was also empty so : 1 I'm trying to do

问题 Using SQL Server 2008.

This all works fine, but I'm wondering how efficient it is. i.e. does SQL server need to read in the whole blob to its memory,

问题 I have a table in which there are two columns : 1. import type, 2. Excel import template. The second column - "Excel import template" should store the whole excel file. How would I save excel file in databse...can I use binary datatype column, convert excel file to bytes and save the same ? Thanks in advance ! 回答1: Yes, you can use a binary file type.
