问题 We've been using SQL Server merge replication for a few years to synchronise data between our data centres, but we are now suffering with a big performance issue. This may be because the amount of data we are synchronising has increased a lot this year. Our publisher is an always-on data centre in the UK. Our subscriber is a mobile data centre that travels around the world and is on for periods of up to a week at a time, approx. 25 times a year. However, it also spends the same amount of time

问题 I have a table (Customer_Master_File) that needs to updated from flat files dumped into a folder. I have an SSIS package that runs to pick up the flat files and imports them into a temp table (temp_Customer_Master_File) What I have been unable to do is this: for each record in the temp table, if the Customer_Number exists in the Master table, update it, if not insert the contents of the temp table. I'm updating all fields of the record, not looking for individual field changes. I tried the

问题 I'm trying to check if there's an existing record on the day before the selected schedule date. How do we do this? I tried using LAG() , but I'm having problem when it comes to sorting out the data because of the NULL . DATEDIFF() won't solve my problem as well because I need to check if there's an existing data on that date, and not -1 the date. What I want to query if example. Day before 2020-01-02 has recordin and recordout , it should reflect NULL if necessary. Is there a way to do this?

问题 I have been created new database and the log file groth very past, and I get error mesaage that the log is full due to 'BACKUP'. I looked in the differences between this Database and other databases in the SERVER, and I seen that in all databases log_reuse_wait is 0 and log_reuse_wait_desc is NOTHING and in my database log_reuse_wait is 0 and log_reuse_wait_desc is LOG_BACKUP. I want to change this property in my database to 0 and NOTHING. How can I do that? 回答1: This is a read-only status

问题 I have XML data which I need to convert to relational form. I use XQuery cause I don't know the number of address nodes. I'd like to get the whole address/adresses separeted by a comma. I guess I need to use LET clause but I'm still receiving an error. Here's my code: declare @xml as xml = '<root> <Row> <proceeding> <signatures>V GU 86/18</signatures> <signatures>V GUp 9/19</signatures> <signatures>V GUp 8/19</signatures> </proceeding> <entity> <info> <cleaned_name>Kate Smith</cleaned_name> <

问题 I have a problem with sys.columns for inline functions. Maybe an error of SQL Server or I'm missing something? Let's start from beginning, I have a simple table and a simple function like these: DROP TABLE [dbo].[SimpleTable] GO CREATE TABLE [dbo].[SimpleTable]( [id] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED, [descr] [varchar](50) NULL ) GO DROP VIEW SimpleView GO CREATE VIEW SimpleView AS SELECT * FROM SimpleTable GO DROP FUNCTION SimpleFunction GO CREATE FUNCTION SimpleFunction(

问题 I am using Sql Profiler all the time to capture the SQL statements and rerun problematic ones. Very useful. However, some code uses the SqlBulkCopy API and I have no idea how to capture those. I see creation of temp tables, but nothing that populates them. Seems like SqlBulkCopy bypasses Sql Profiler or I do not capture the right events. 回答1: Capturing event info for bulk insert operations ( BCP.EXE , SqlBulkCopy , and I assume BULK INSERT , and OPENROWSET(BULK... ) is possible, but you won't
