问题 I am trying to select certain customers from a contacts table if they do not have a guardian listed. ClientId | ContactId | Guardian 123 | 1 | Y 123 | 2 | N 123 | 3 | N 456 | 4 | N 456 | 5 | N 456 | 6 | N Desired output: ClientId | ContactId | Guardian 456 | 4 | N 456 | 5 | N 456 | 6 | N So my goal is that Client 456 would show up in my query results, but not Client 123. I have written the following: select * from Contacts where Guardian <> (case when Guardian = 'Y' then Guardian else '' end)

问题 For an application, I need to show search results based upon multiple columns. Searching in multiple columns is not that hard, but I also want to know which column(s) the search query matches the text. Imagine following 'Blabla' table: --------------------------------------------------------------------------------------- | column1 | column2 | column 3 | --------------------------------------------------------------------------------------- | Animals are beautiful | Some text regarding music

问题 The Scenario Let's suppose we have a set of database tables that represent four key concepts: Entity Types (e.g. account, client, etc.) Entities (e.g. instances of the above Entity Types) Cohorts (a named group) Cohort Members (the Entities that form up the membership of a Cohort) The rules around Cohorts are: A Cohort always has at least one Cohort Member. A Cohorts Members must be unique to that Cohort (i.e. Entity 5 cannot be a member of Cohort 3 twice, though it could be a member of

问题 I have this query SELECT CASE WHEN dbo.CFE_PPHY.P77 IS NOT NULL OR dbo.CFE_PPHY.P77 <>'' THEN MONTH(dbo.CFE_PPHY.P77) WHEN dbo.CFE_PPHY.P70 IS NOT NULL OR dbo.CFE_PPHY.P70 <>'' THEN MONTH(dbo.CFE_SERVICE_EVTS.C10_2) ELSE COALESCE(CONVERT(VARCHAR,dbo.CFE_PPHY.P77)+ CONVERT(VARCHAR,dbo.CFE_SERVICE_EVTS.C10_2),'toto') END AS CFELiasse_DateEffetEIRL_MM_N FROM CFE_PPHY LEFT JOIN CFE_SERVICE_EVTS ON CFE_PPHY.colA = CFE_SERVICE_EVTS.colB The ELSE part is giving me headaches. The columns CFE_PPHY.P77

问题 I have a source table that looks like this: +--------------+----------+------+------------+-----------+ | vehicleindex | parentid | year | make | model | +--------------+----------+------+------------+-----------+ | 1 | 1 | 2007 | TOYOTA | SIENNA LE | | 2 | 1 | 2005 | VOLKSWAGEN | JETTA GLS | +--------------+----------+------+------------+-----------+ I'd like to select from this table such that the output looks like this: +-------+--------+-----------+-------+------------+-----------+ |

问题 I need to replicate a simple procedure from Java code to SQL Server stored procedure. It will go into a SQL Azure db in production, but I'm testing it against my local SQL Express 12 install. A part of this stored procedure is to concatenate some values into a string. This is my example Java code: import java.sql.Timestamp; import java.text.DateFormat; import java.text.ParseException; import java.text.SimpleDateFormat; import com.google.common.base.Strings; public static String concat() { /

问题 I need a stored procedure to generate @n records, each with a unique random 8 digit number. This number must not be incremental and must not exist already in the table. CREATE TABLE Codes ( ID UNIQUEIDENTIFIER PRIMARY KEY, Code INT, CONSTRAINT UQ_Code UNIQUE(Code) ); I can generate random numbers: DECLARE @min int = 0, @max int = 99999999, @n INT = 100; SELECT TOP (@n) FLOOR(CAST(CRYPT_GEN_RANDOM(4) AS BIGINT) / 4294967296 * ((@max - @min) + 1)) + @min FROM sys.all_objects s1 CROSS JOIN sys

问题 I am trying to get some sorting and keep together (not really grouping) working. In my sample data I would like to keep the DealerIDs together, sorted by IsPrimaryDealer DESC, but show the group (ok maybe it is grouping) of dealers by the ones with the most recent entry. Result set 2 is the closest, but Grant and his brother should be displayed as the first two rows, in that order. (Grant should be row 1, Grants Brother row 2 because Grants Brother was the most recently added) DECLARE @temp
