inner join

For the past several editions. SQL Books On-Line (BOL) has helpfully included a script to rebuild or defragment (since 2000) an index. Being Microsoft this script is NOT located under the reindex or defragmentation topic it is included in the fragmentation analysis section. For SQL 2000 this is DBCC SHOWCONTIG. For SQL 2005 they rewrote it to use the new system views and stashed it under sys dm_db_physical_stats. It also uses the new ALTER INDEX command rather than the older DBCC DBREINDEX or DBCC INDEXDEFRAG command. However this script does not allow you to take advantage of online indexing My first attempt to modify the script consisted of dropping the defragmentation option and simply adding a WITH ONLINE = ON line to the script. As with most quick and dirty mods this failed miserably. I soon discovered that some indexes cannot be rebuilt online. There are two conditions that will prevent online reindexing both of which involve BLOB data types: You cannot online reindex a non-clustered index that contains a BLOB column. You cannot online reindex a clustered index of a table that contains a BLOB column. Pretty straightforward or so it seems. The code to identify BLOB columns from an index is a bit tricky but not too impossible. I used actual data type names rather than the internal data type IDs to make the code more readable. I also added a filter condition to remove "trivial" sized indexes. These are typically allocated into mixed extents and do not respond to defragmentation. There is no real harm in including them but they clutter up the result set when troubleshooting. I kept tweaking the number until I got it as low as possible without an index reappearing in subsequent runs. The test platform was a Microsoft CRM implementation. For those unfamiliar with the table design of MSCRM it uses GUIDs as primary keys and accepts the default of clustering the primary key. This makes for a nicely fragmented database to test especially if there is a lot of insert and delete activity. So without further ado here is the modified BOL code that allows for scripting online index rebuilds. FROM sys dm_db_index_physical_stats (DB_ID(). NULL. NULL. NULL. 'LIMITED') WHERE avg_fragmentation_in_percent > @MaxFragmentation -- arbitrary threshold. YMMV     and page_count > @TrivialPageCount -- ignore trivial sized indexes -- Declare the cursor for the list of partitions to be processed. SELECT @objectname = QUOTENAME(o name). @schemaname = QUOTENAME(s name)             JOIN sys schemas as s ON s schema_id = o schema_id         if @indexid = 1 -- only check here for clustered indexes ANY blob column on the table counts             Select @HasBlobColumn = case when max(so object_ID) IS NULL then 0 else 1 end                     on SO. Object_id = SC object_id                     on SC system_type_id = ST system_type_id                     and ST name in ('text'. 'ntext'. 'image'. 'varchar(max)'. 'nvarchar(max)'. 'varbinary(max)'. 'xml')                 where SO. Object_ID = @objectID             else -- nonclustered. Only need to check if indexed column is a BLOB             Select @HasBlobColumn = case when max(so object_ID) IS NULL then 0 else 1 end                 inner join sys index_columns SIC                     on SO. Object_ID = SIC object_id                     on SO. Object_ID = SI. Object_ID                     and SIC index_id = SI index_id                     on SO. Object_id = SC object_id                     and SIC. Column_id = SC column_id                     on SC system_type_id = ST system_type_id                     and ST name in ('text'. 'ntext'. 'image'. 'varchar(max)'. 'nvarchar(max)'. 'varbinary(max)'. 'xml')                 where SO. Object_ID = @objectID         SET @command = N'ALTER INDEX ' + @indexname + N' ON ' + @schemaname + N'.' + @objectname + N' REBUILD';             Set @command = @command + N' WITH( SORT_IN_TEMPDB = ON) ' SET @command = @command + N' PARTITION=' + CAST(@partitionnum AS nvarchar(10)); PRINT N'Executing: ' + @command + ' Has Blob = ' + convert(nvarchar(2),@HasBlobColumn); Geoff you should also add a check of the server version because Standard Edition and Woorkgroup Edition don't support Online Index operations. In my own script I useIF SERVERPROPERTY('EngineEdition')=3 --> Then online operation is possible

Hi all,I just written an inner join statement but would desire to run another INNER JOIN against the results of the first INNER JOIN. Is this possble? If so how?Thanks. Matt think of it just like joining two tables together. It is really the same thing. You are basically joining the result set of the first join with the 3rd table select * from tablea a inner join tableb b (on a id = b id) inner join tablec c on (b id2 = c id2);I accept this would work the same:select * from tablea a tableb b tablec c where a id = b id and b id2 = c id2There is also natural inner joins will give you a 'cleaner' create if the names are the same in the tables to do anything further you will undergo to give some more info This will only go results the match the 'on' restrictions in each join.

95% of visitors never choose ever! Vote for just 3 new links per day and you'll enjoy a better DZone. I have been playing with LINQ from quite a few days I should say I am impressed with it. It does nearly everything out of box. Yes nearly every thing out of box. And the ORM is also very very powerful. In This post I will dilate how to use Joins in LINQ queries.

i guess theres no difference between the two aside from declaring what write of join you want i anticipate theres no difference between the two aside from declaring what type of join you want yes i was thinking that way but i have tried join it self and it works and gives same create as inner join so i guess we move say join implies inner join because join clause work without declaring what type of join you be yes i was thinking that way but i have tried join it self and it works and gives same output as inner join so i guess we cant say join implies inner join because join clause bring home the bacon without declaring what type of join you want @fenwayyou said join JOIN implies INNER connect... but join it self works without inner join i can do something like thisselect * from tablejoin delay1 on etccc... also decide * from tableinner join delay1 on etccc... so i guess this question Can someone inform the difference between inner join v/s join. gratify be an answer (but not join connect implies INNER JOIN.... ) well my bad because the only difference i knew about the two is what i have stated above Fenway is saying that join and inner join are identical. The reason he said "implies" is because JOIN means INNER connect and never any other type of join. You've probably noticed that the results are identical for every example you try. That's because they ARE identical for every example in the universe 0 && this options[this selectedIndex] determine) window location href = smf_scripturl + this options[this selectedIndex] value substr(smf_scripturl indexOf('?') == -1 || this options[this selectedIndex] determine substr(0. 1) != '?' ? 0 : 1);">

Hi all,I am currently trying to feature 2 queries (ask 1 and query 2) together such that ask 2 automatically runs after query 1. I have gone through some of the previous threads on running a series of queries but undergo yet to attain my desired results. Before I act advance.. I undergo pasted my queries below for easier comprehension ask 1: PARAMETERS choice TEXT;decide * FROM [CustomerDetails delay] WHERE [branch] = choice;ps: (data from query 1 ordain go into SelectedRecords table)query 2:modify(SELECT [T1].*. [no] FROM (decide [ID]. [avg_age] FROM [table1]) AS [T1] INNER JOIN (decide [G].[ID]. Avg([R].[age]) AS [no] FROM [allcustomers] AS [G] INNER JOIN [SelectedRecords] [R] ON Contains([G].[ID]. [R].[ID]) GROUP BY [G].[ID]) AS [T2] ON [T1].[ID] = [T2].[ID])SET [avg_age] = [no];Thanks to Lorne and KlausDE. I managed to run ask 1 successfully using their prescribed wrapper technique that incorporates parameters (#46180). However query 2 failed to run due to it being an modify query. (i speculate this is the reason behind it but i am not sure) I have tried manipulating query 2 and have failed time and time again! =( To alter it worse. I understand that I would demand a vb script as well and I undergo no undergo in it. Can somebody pls help me? Disheartened,Crystaline
