问题 In MS Excel, if you create a QueryTable with Microsoft Query, and your SQL query cannot be visually presented by Microsoft Query, then you are not allowed to provide parameters for that query. Which is a shame, so there is this awesome technique that allows parameters anyway: {CALL sp_executesql (N'select top (@a) * from mytable', N'@a int', ?)} You provide the query in the ODBC CALL form and it works with parameters. Unless it does not. While on some computers it works flawlessly, on other

问题 Goal: Return a dataset showing time differences between successive events of the same type Table Structure: CREATE TABLE [dbo].[Event]( [EventID] [int] IDENTITY(1,1) NOT NULL, [JobID] [int] NOT NULL, --FK to Job Table [LastRun] [datetime] NOT NULL, [LastRunEnd] [datetime] NULL, [LastRunResult] [int] NOT NULL, --FK to Result ) ON [PRIMARY] --Event ID is PK Since the data comes from sequential events, LastRun will always increase for each job.

问题 we are trying to transfer data from DB2 -> SQL Server 2014 database. When using SSIS to transfer data between tables, the timestamp -> datetime2 is failing due to data type mismatch. Found couple of links related to that, but not sure if they have the source db2 Timestamp column data converted to string format before applying those conversions or data is coming in as Timestamp type and those conversions could still work? please share how to handle this Timestamp -> Datetime2 mismatch in SSIS.

问题 This question "Need a case insensitive collation where ss != ß" solves it for varchar type column, but mine has to be nvarchar . As far as I can gather, SQL_Latin1_General_Cp437_BIN differentiates between ß and ss . But it is also case-sensitive. Mine is a primary key column which also needs to be case INsensitive: I need e.g. weiß / Weiß to be considered equal, and also weiss / Weiss , but NOT weiß / weiss nor Weiß / Weiss nor weiß / Weiss etc. I've searched a lot for this, and is it really

问题 We have a SQL Server 2012 instance, with auto-statitics set to ON for the DB: But then i ran a query to check some statistics, and some haven't been updated in a while: Why is this the case? Is there a rule to whether SQL Server updates statistics that haven't been triggered by these indexes? Do i need to care? How do i know if i need to update them, or if they are causing performance issues for me? Thanks! 回答1: Even though you set Auto update statistics to true, they will update only when a

问题 When you use default value for a column in SQL Server Management Studio table designer, SSMS change your default and stand Parenthesis around of that (In all editions and all versions of SQL Server). For example if you set 0 as default value, this default changed to (0) . I don't know why sql server use parenthesis, and is there a practical reason. Thanks in advance. 回答1: There are certain types of objects, such as DEFAULT s and CHECK constraints that SQL Server doesn't store the original,

问题 I've got a very huge table with hierarchy which can not be modified. Nodes in the table have an Id , ParentId , a Level and some data. The Level means that node with level N can be a child not only for level N-1 but also for level N-2 , N-3 etc. The good news are that the number of levels is limited - there are only 8 of them. Level 1 is on the top of the hierarchy and level 8 is the end of it. And now I need to flatten that table with respect to the place of the levels. The result should be
