instesd of displaysing GroupId, SystemId,DeviceId i need to diplay the SensorName,GroupName,SystemName,DeviceName. so please give me some example query to join multiple tables please
Hi all, I am trying to join 2 tables in my database on an encrypted column. I am using a symmetric encryption, but because of the IV, a string encrypted at 2 different times produces 2 different encrypted strings. Therefore, I can not merely join the 2 tables on the encrypted columns. Has anyone any insight on techniques for solving this problem? The most naïve way, would be to decrypt both tables, join them, and re-encrypt them again. But, the tables are quite large, and this would be very processor (and time) intensive. Any help would be greatly appreciated. Thanks in advance for any suggestions.
I need to write a sql query which is a master-detail query. Here's the example structure of tables:
Master table: ColID as longint, ColA as int, ColB as int, ColPartID as longint, ColPartName as longint
Child table -- Wheel: ColID as longint, ColA as int, ColB as int Child table -- Door: ColID as longint, ColA as int, ColB as int Child table -- Window: ColID as longint, ColA as int, ColB as int ..... etc
From the master table, it needs to join with its child in order to get the detailed information. However, there're more than one child table for it to join. In other words, the query has to choose the correct child table to join for each row selectively. The use of correct child depends on one of the columns in its master table (ColPartName).
My question is: Does it worth of me keep finding a solution for this query or should I abandon this? I really need some advice, please.
I find that joining to the same table twice is OK, but as soon as you do it 3 or more times you get a massive performance hit. Does anyone know the reason for this? Whats special about 3? What's the best approach to do this sort of thing? (I've used the SQL Server 2005 Tuning Advisor to add indexes for the query).
Rather than: Select ..., sum(a1.<column>), sum(a2.<column>), sum(a3.<column>) from master_table left join table_1 a1 on ... left join table_1 a2 on ... left join table_1 a3 on ... group by ...
I have to select all the table and filter it using case: Select ..., sum(case when table_1.<column> = '...') as a1, sum(case when table_1.<column> = '...') as a2, sum(case when table_1.<column> = '...') as a3, from master_table left join table_1 group by ...
Hi All,Bit of a newbie question i'm afraid, so sorry if this is a reallystupid question,I am not sure if I am trying to do this in the right place as I am sureSQL Server has a far better way of doing thisWhat I am trying to do is join the contents of several columns andpresent the entry into a new column. the entries of all the columns Iam trying to join are different types such as dates and numbers. I wantto join all columns as a text string. To make it just a even moretricky I wish to insert a # between all fields.Just in case my poor description has got you thinking What the F*&Khere is an example of what I am trying to doC1 C2 C3 C4 C5Ian 1234 22/02/2006 123456789 Ian#1234#22/02/2006#1234567890I have been trying to do this in the Formula in the design veiw of thetable.Any Advice would be fantastic.Many ThankIan

this is the Select statment I am trying to use so that I can update the Asset in Assets table and the ESN number in the ESN table. But using ESNId and AssetId.
This is my query that returns the ones are not assigned to and Asset
SELECT DISTINCT EsnId, EsnNumber FROM dbo.ESNTracking WHERE (EsnId NOT IN (SELECT EsnId FROM dbo.EsnAsset))
I imported data into a database and the first character in an ID Field starts with %. This is causing many problems for the application. Unfortunately, this field exists in 72 of 128 tables in the database. Is there a way to LTRIM every ID field where the first character is %? This is easy in 1 Table but how do I apply it to all 72 tables at once? Thanks for for your assistance
Hi,I have a 2 tables called 1.tblRisk which consists of Ref(pk), subject, status, staff & Dept(fk)2.tblDept which has Ref(Pk) & DepartmentHow do i get it to populate Department, when tblRisk Ref's Dept matches the Ref in tblDept i am using SQL Server 2000best regards
I have two tables tbl1 and tbl2, which I do a full outer join between tbl1 and tbl2 on recordId field. The recordId field is not a key in either of the tables.
If there is one row each for a recordId 123 in both tables, the select query would return one combined row.
If tble1 had two rows for recordId 123, and tbl2 had one row for the same, it would return to rows repeating the data in tbl2.
If tbl2 had two rows and bl1 had one row, it would return two rows in output repeating the data in tbl1.
Is the above correct? Would the result be different if it was an inner join instead of full outer join?
Is it ever possible that one of the two records with recordId 123 will be dropped from the result?
I'm managing an amature online university and I've been charged with creating a deans list. I have a table for exam results for each course.. currently totaling 5. I have an employeeID column and a total_points column in each table. Sooooo I need to join all the tables and get an average for total_points where the employeeID matches across tables. I have no idea how to write this select.. any help?
Is there a way ,(if so what is the syntax?), to set up a DTS package that loads a table that has an identity column. I am trying to load the data from another table, (leaving the identity field unmapped), and de-selecting the "enable identity insert" from the advanced tab of the Data Transformation Properties window. I keep getting errors due to the table not allowing null values. I tried using the set_identity command, but this still did not work. Any help would be appreciated. TB
This is feeling very hard for me, but is surely very easy for many of you. I have 2 Tables. "Events" and "Meals". Both have a columns named "EventDate" and "EventTime". I need to be able to compile a list of both and sort by event date and time. For example, a Meal @ 5:30 would place itself between a 4:00 Event, and a 6:30 Event.
I know there is some kind of rule against the following SQL statement, but I was wondering what to do to get around this problem (some kind of grouping). Sorry for the stupid question.
SELECT * FROM Table1, Table2 WHERE Table1.ID IS NOT NULL AND Table2.ID IS NOT NULL
Basically I want to select all records from the two tables (they have the same fields, but are just different specialties) and then output them, but there is nothing in common between the two to reference one another, and it ends up in some kind of loop. Thanks. for the help.
I have a table activity which show the activities of the site. An activity could be related with no other entity or it could be related with an account, or with a contact or with an opportunity. An opportunity and a contact could be also related with an account.
My problem is that I need to show the activity and the related account (if there is any) but because the relationship with an account could be done by different ways, I dont know how to do it without join the account table several times.
This is my current query:
SELECT AC.IdActividad, CU.idcuenta FROM Actividades AC LEFT JOIN Tareas TA ON TA.IdActividad = C.IdActividad LEFT JOIN ActividadesXCuenta AXC ON AC.IdActividad = AXC.IdActividad LEFT JOIN dbo.Cuentas CU ON axc.IdCuenta = CU.IdCuenta LEFT JOIN dbo.ActividadesXOportunidad axo ON AC.IdActividad = axo.IdActividad LEFT JOIN dbo.Oportunidades o ON axo.IdOportunidad = o.IdOportunidad LEFT JOIN dbo.Cuentas CU1 ON o.IdCuenta = CU.IdCuenta LEFT JOIN dbo.ActividadesXContacto axco ON AC.IdActividad = axco.IdActividad LEFT JOIN dbo.Contactos con ON axco.IdContacto = con.IdContacto LEFT JOIN dbo.Cuentas CU2 ON o.IdCuenta = CU.IdCuenta
As you see, I have the table Cuenta joined 3 times. That means that I need to put the ActivityID field 3 times but based on how the report was developed, I could not do that.
I have two tables: TestA and TestB. Both tables have 3 fields: ID,Name, and RunDate. I need to create a query which will join the twotables first on Name but then I need to match up the RunDates eventhough the RunDates won't be the same.CREATE TABLE TestA (ID INT IDENTITY, Name VARCHAR(255), RunDateDATETIME)CREATE TABLE TestB (ID INT IDENTITY, Name VARCHAR(255), RunDateDATETIME)INSERT INTO TestA VALUES ('Account 1', '9/1/2004 12:00PM')INSERT INTO TestB VALUES ('Account 1', '9/1/2004 12:15PM')INSERT INTO TestA VALUES ('Account 1', '9/2/2004 1:00PM')INSERT INTO TestB VALUES ('Account 1', '9/2/2004 1:15PM')INSERT INTO TestA VALUES ('Account 1', '9/3/2004 3:00PM')INSERT INTO TestA VALUES ('Account 2', '9/5/2004 4:00PM')INSERT INTO TestB VALUES ('Account 2', '9/5/2004 4:15PM')Here's a common scenario:User updates TestA data for Account 1 on 9/1/2004 at 12:00pm. Thenthe user updates TestB data for Account 1, 15 minutes later. I wantthese two records to match. The user must always update TestA databefore they update TestB data. Therefore, there might be more rows inTestA then in TestBHere's what the results should look like for the above data.Name TestA Date TestB Date---- ---------- ----------Account 1 9/1/2004 12:00pm 9/1/2004 12:15PMAccount 1 9/2/2004 1:00pm 9/2/2004 1:15PMAccount 1 9/3/2004 3:00pm (NULL)Account 2 9/5/2004 4:00pm 9/5/2004 4:15PMAny help would be much appreciated!!!!
I want to group by a fields value in a table. I have a purchase table where contracts and orders are stored in together. Now what I need is, I have to group only by the rows that contain an identical contract_no and order_no as those records represent the actual contract. the other rows contain order data-sets which need to be subtracted from the contracts values.
Here is my situation. I am building a report that has three different tables each with their own dataset. Example: Opportunities, Leads, Activities. All three of these datasets/tables have a common field - SalesID. I would like the report to show the first SalesID, then all Opportunities for that SalesID in the Opportunities table, followed by all Leads for that SalesID in the Leads table, followed by all Activities for that SalesID in the Activities table, and then rollover to the next SalesID and repeat that for all SalesIDs. Any suggestions on how I could achieve this? Thanks in advance for all help!!!
I have a sql query that I am using to populate a datagrid. The problem is one of the tables is a month table. and the other tables are full of data. So there is no common column name to match using a inner join "on".
I am trying to join two tables together, on the same field except they have different data types, see the properties below
Code: TableCOLUMN_NAMEDATA_TYPECHARACTER MAXIMUM LENGTHCHARACTER OCTET LENGTHCHARACTER SET NAMECOLLATION NAME 1itemClassnvarchar 512 1024 UNICODE Latin1_General_CI_AI 2PGCode varchar 3 3 iso_1 Latin1_General_CI_AS in the code for the join,
Code: left join common.dbo.qryPRDGroupDets on CAST(qryData_GB1_ByColumn.itemclass as varchar(3)) = Cast(common.dbo.qryPRDGroupDets.PGCode as varchar(3))
I have tried using the CAST function on one side of the join then on both, to no avail...
I have a script that is supposed to run thru 2 joined tables and update a field in the 3rd table. The script works but takes approx. 4 hours to run against 250k records.

I need to migrate data from one sql database to another. The second DBis a newer version of the "old" database with mostly the same tablesand fieldnames. In order support some reporting queries in the "new"version I needed to change the datatype of a few fields from varchar toint(the data stored was integers already as they were lookup tables).DTS works great except in the cases of about 10 fields which I changedthe datatypes on from varchar to int.DTS seems to drop the data if the fieldname and datatype are not anexact match. Is there any way to use DTS and have it copy data from afield call subsid type varchar to a field call subsid type int?

Conditional Update of a field from multiple tables..I have a target table with two fields: Date and ID..There three source tables: S1, S2, S3, each of them has three fields: Date, ID, and Score...Now I want to update the target table: put the ID into the ID field which has the highest Score from the three tables on each day.
I am trying to create 2 tables, one (Table 1) having:
Id DateCreated DateUpdated RequestType RequestTypeId StatusType StatusTypeIsClosed
The other (Table 2) with:
Id DateCreated Key Value
Ultimately, these 2 table will be joined on Id. Here is the SQL, Table 1 creates properly, and Table 2 creates, but right now 'Id' comes in as NULL. How do I add the Id field from the upper node into Table 2 (excuse my terminology if it is incorrect) ?Â
