问题 I would like to set a stored procedure to always execute as a specific domain user. Regardless of the user calling or trying to execute the procedure, can I force the procedure to be executed as another user.

Unfortunately we cannot be storing the csv files on the local database server and need to place them on a network share. Therefore I need to set these procedures

问题 I was happy to find you can use an Excel-like YEARFRAC function in MS SQL server (http://technet.microsoft.com/en-us/library/ee634405.aspx), but for some reason I get an error that states: 'yearfrac' is not a recognized built-in function name when I try to run my query. Here is my code: SELECT CUSTOMER_ID, PRODUCT_SKU, SUB_START_DATE, SUB_EXP_DATE, YEARFRAC(sub_start_date, sub_exp_date) AS START_TO_END FROM ... For the record, I have double-checked the dates are in proper datetime format, and

问题 A 3rd party application accessing a SQL Server 2012 database is getting [Microsoft][ODBC SQL Server Driver]Query timeout expired errors after executing for about 20 mins. This is what I see on the database after the application starts receiving the errors: SPID 102 is not shown in the query above. It is another connection from the same application for the same process. I was able to capture some details of this in the screenshot below. It is the one in the topmost row in this screenshot.

问题 I have a #temp table where I have names of stored procedures. DECLARE @object VARCHAR(200) SET @object = (SELECT Top 1 Te.[this Object...] From #Temp Te) IF OBJECT_ID(@object) IS NOT NULL DROP PROCEDURE @object But on last step I get error Incorrect syntax near '@object'. Is this because @object is of type VARCHAR or what ? This is for SQL Server 2012 回答1: you can't do it like that. You need to use dynamic sql. Something like : DECLARE @object NVARCHAR(200) DECLARE @sql NVARCHAR(max) SET

问题 I've the following problem I need to solve in SQL. Let's say that I have a table with 2 columns: Date | Code -------- 0 | 25 1 | 22 2 | 23 3 | 25 4 | 23 5 | 21 And I need to keep a count of them, as the Date is relevant for me.

问题 we developed a WCF service ( running on windows server 2012) and client API which are connected each other with client certificate authentication. They were running cool up to we made a stress test on system. We try to load system with giant data then the system responds so slowly. So we interrupt the process and try to clear DB. The clearing and reindexing DB took more than 6 hours. After that the WCF service stoped responding! But we did not change any code block! Therefore, I think that

问题 I'm trying to write a function to replace the Romanian diacritic letters ( ĂÂÎȘȚ ) to their Latin letter equivalents ( AAIST , respectively). SQL Server's replace function deals with Ă , Â , and Î just fine. It seems to have a weird problem with Ș and Ț , though: they are only replaced if they are found at the beginning of the string. For example: select replace(N'Ș', N'Ș', N'-') -- '-' # OK select replace(N'ȘA', N'Ș', N'-') -- '-A' # OK select replace(N'AȘ', N'Ș', N'-') -- 'AȘ' # WHAT??
