问题 I am using SQL Server 2008 DDL CREATE TABLE [dbo].[t]( [words] [varchar](1000) NULL, [id] [int] IDENTITY(1,1) NOT NULL ) ON [PRIMARY] DML insert into t(words)values('this is my laptop') insert into t(words)values('this does not contains headphone') SQL Query SELECT * FROM t as t JOIN CONTAINSTABLE(t, words,'"headphone*"', 10) fulltextSearch ON t.Id = fulltextSearch.[KEY] Results No record found I am expecting one records. Any Idea? 回答1: 'this' is very likely a noise word (like 'the', 'and',

问题 I'm trying to return a table with the depth of a node in a hierarchy represented using the nested set model, I'm following this tutorial but the query used in the section 'Finding the depth of Nodes' doesn't work for me: http://mikehillyer.com/articles/managing-hierarchical-data-in-mysql/ SELECT node.GroupName, (COUNT(parent.GroupName) - 1) AS depth FROM CompanyGroup AS node, CompanyGroup AS parent WHERE node.LeftID BETWEEN parent.LeftID AND parent.RightID GROUP BY node.GroupName ORDER BY

问题 The setup is like this: Col1 Col2 12345 12 12348 14 20145 16 00541 Null 51234 22 Simplified, obviously. What I want to do is update Col2 wherever it's Null by setting it to the Col2 value for whatever has the closest value in Col1 (so in this example, row four should have Col2 set to 12). This is how close I've gotten: UPDATE Temp.dbo.Sheet4 SET Col2 = (SELECT FIRST(Col2) FROM Temp.dbo.Sheet4 WHERE Col2 IS NOT NULL ORDER BY ABS(***Col1 from the outside of this select statement*** - Col1))

Can i get the output like below by using a query? I need the dates in one month to be

问题 I want to update some data in a specified case, else these columns are not to be updated. What can I write code in a stored procedure for this? 回答1: You can use a case to control whether you assign a new value or keep the old value. update <sometable> set field = case when <condition> then <newvalue> else field end where <condition> Example: update questions set reply = case when @input is not null then @input else reply end where answer = 42 回答2: Use Case statement in Update clause like SQL

问题 I have an application which creates datarequests which can be quite complex. These need to be stored in the database as tables. An outline of a datarequest (as XML) would be... <datarequest> <datatask view="vw_ContractData" db="reporting" index="1"> <datefilter modifier="w0"> <filter index="1" datatype="d" column="Contract Date" param1="2009-10-19 12:00:00" param2="2012-09-27 12:00:00" daterange="" operation="Between" /> </datefilter> <filters> <alternation index="1"> <filter index="1"

问题 I am relatively new to writing SQL. I have a requirement where I have to display the top 5 records as it is and consolidate the rest as 1 single record and append it as the 6th record. I know top 5 selects the top 5 records, but I am finding it difficult to put together a logic to consolidate the rest of the records and append it at the bottom of the result set. weekof sales year weekno ------------------------------------------------------------- 07/01 - 07/07 2 2012 26 07/08 - 07/14 2 2012

问题 I've implemented an auditing trigger on one of my tables, it basically copies the old record and the new record into a table called ..._Audit, along with date and user. I'll post my script further down. The problem is that, when I insert a new record in Access then tab across, it refreshes and shows the first record in the table. An example of this is below - I have added the first three records then refreshed, then I added three more of the exact same data After adding them I should be

问题 I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query
