I am using 3 tables: projects, project_manager and project_employee
projects
- project_id (int, PK)
- project_name
project_manager
- project_id (int, PK)
- manager_id (int, PK)
project_employee
- project_id (int, PK)
- employee_id (int, PK)
Assume that a manager is currently logged in (so we know what is his ID), what I trying to do is write a query that will display a grid-view showing:
project_id, project_name and number of employees in project.
I tried these quires to test:
SELECT project_id, count(emp_id) as NumberOfEmployees into #tempTable FROM project_employee WHERE project_id IN (SELECT project_id FrOM projects) GROUP BY project_id
SELECT projects.project_id, projects.project_name, NumberOfEmployees FROM projects, #tempTable WHERE projects.project_id = #tempTable.project_id
Problems are:
1 - I used two queries not one
2 - The result is for all projects of all managers, I just want to display projects for a specific manager (for example mag_id = 5)
3 - it created a temporary table - which I dont want.
Is there anyway to get what I want in a single query?
I have two tables that have no relation. However, both have a column which has a field of nvarchar(50) that I want to retrieve together in one operation and bind to a DropDownList in a sorted fashion. So, what I'm trying to achieve is this: 1. SELECT name FROM table1 2. SELECT name FROM table2 3. Join the two results together and order them alphabetically 4. Return the result set I'm not sure how to do this or even if it's possible. Ideally I'm hoping it can be done in a stored proc.
hello i am a beginner i it possible to get this result by single query ?
i got a int column and a datetime column is it possible to get the sum(int column) for all the year 2007 and by the april2007 and by the month n year by the person name Tony
I have a table with 1 column containing numeric values, and I need to create a query which displays the count of values for each set of conditions. For example, if the table contains the values 1,2,3,4,5 and 6, the output of the query should look like this:
L M H ----------------------- 3 2 1
(L are values below 4, M between 4 and 5, H is 6 and above)
Here the SELECT query is fetching the records corresponding to ITEM_DESCRIPTION in 5 separate transactions. How to change the cursor to display the 5 records in at a time in single transactions.
CREATE TABLE #ITEMS (ITEM_ID uniqueidentifier NOT NULL, ITEM_DESCRIPTION VARCHAR(250) NOT NULL)INSERT INTO #ITEMSVALUES(NEWID(), 'This is a wonderful car'),(NEWID(), 'This is a fast bike'),(NEWID(), 'This is a expensive aeroplane'),(NEWID(), 'This is a cheap bicycle'),(NEWID(), 'This is a dream holiday') --- DECLARE @ITEM_ID uniqueidentifier DECLARE ITEM_CURSOR CURSOR
dear all i need to write SQL Query that compares 2 tables as folows: lets say i have: table A with A.A, A.B, A.C columns (Table A with Columns A,B,C) table B with B.A, B.B, B.C columns (Table B with Columns A,B,C)
i need to compare and to mark (get in result Query) each row lets say in table B that was changed from table A
For Example Table A A B C 12 15 hello 15 17 adv asd 19 23 14 rer 89
Table B A B C 12 15 hello 15 19 adv *** 19 23 14 rer 89
the result is the records which was changed from A to B
Is there any way to update multiple tables in a single query. I know we can write triggers. Apart from triggers, is there any other way available in SQL Server. I am using 2008R2.
Here with the below query iam binding my gridview with industry name,company name,Plant Name,Group Name related to the IDs in Audit table.Select Aud.Ad_ID_PK,Aud.Audit_Name,Ind.Industry_Name,Cmp.Company_Name,Pla.Plant_Name,Gr.Groups_Name,Aud.Audit_Started_On,Aud.Audit_Scheduledto,Aud.Audit_Created_On from Industry Ind, Company Cmp, Plant Pla, Groups Gr, Audits Audwhere Ind.Ind_Id_PK =Aud.Audit_Industry and Cmp.Cmp_ID_PK =Aud.Audit_Company and Pla.Pl_ID_PK =Aud.Audit_Plant and Gr.G_ID_PK =Aud.Audit_Group and Ad_ID_PK in (select Ad_ID_PK from Audits) Now i want to edit these names. when i click on edit in gridview these names will be filled into textboxes and when i change the names it should compare the name with particular tables and should get the Id of that and store in Audits table. For example: i have this data in my audits table:
Commercial83312
2 2 2 1 Here Commercial83312 is ID of that Audit and 2,2,2,1 are the Industry,Company,Plant and group Ids for that particular audit.In the front end i can see the names of this particular IDs. when i edit the industry name in the UI it must check the name with industry table and get the ID of the changed name and store it in audit table. so the data may be changed in audits table as :
Commercial83312
4 2 2 1
so here the industry ID is changed I need the stored procedure for this. please help me,its very urgent...
This a microsoft SQL 2000 server. I have a DB with mutliple tables that have a column called "Date_stamp", which is used as a primary ID. Here is my problem: Some of tables have a bad datetime entry for the "Date_stamp". The bad entry is '2008-3-18". I need to delete this entry from every single table that has a name similary to 'Elect_Sub%Daily'.
I know how to get the user table names from the DB as follows:
SELECT name FROM dbo.sysobjects WHERE xtype = 'U' and name like 'Elect_Sub%Daily'
What I need to do is have a query that will basically scroll through the tables name produced by the above query and search and delete the entries that read '2008-3-18".
delete from tableName where Date_Stamp = '2008-3-18'
HI, I ran a select * from customers where state ='va', this is the result...

As the topic suggests I need the end results to show a list of shows and their dates ordered by date DESC. Tables I have are structured as follows:
SHOWS showID showTitle
SHOWACCESS showID remoteID
VIDEOS videoDate showID
SQL is as follows:
SELECT shows.showID AS showID, shows.showTitle AS showTitle, (SELECT MAX(videos.videoFilmDate) AS vidDate FROM videos WHERE videos.showID = shows.showID) FROM shows, showAccess WHERE shows.showID = showAccess.showID AND showAccess.remoteID=21 ORDER BY vidDate DESC;
I had it ordering by showTitle and it worked fine, but I need it to order by vidDate. Can anyone shed some light on where I am going wrong?
CREATE Table #Table1 ( ID INT, Name VARCHAR(50), Class VARCHAR(10) ) INSERT INTO #Table1 Select 1, 'name1', 'a' UNION ALL Select 2, 'name1', 'a' UNION ALL
[Code] ....
Is it possible to have each name and its corresponding class in a single line separated by commas to give a result like the one below in #table2 ?
CREATE Table #Table2 ( ID INT, CommaSeparated VARCHAR(100) ) INSERT INTO #Table2 Select 1, 'name1, a' UNION ALL
[Code] ...
What I have
Select * FROM #Table1
Final Result Select * FROM #Table2
Note that I still want to see all the IDs regardless.
If that is not possible to see all the IDs, I think the results below in #Table3 should suffice.
CREATE Table #Table3 ( CommaSeparated VARCHAR(100) ) INSERT INTO #Table3 Select 'name1, a' UNION ALL Select 'name2, b, c, d' UNION ALL Select 'name3, e, f' Select * FROM #Table3
Hello, I have an SQL problem that is hard to describe so here's an example scenario:
a) company has a personnel database, identifying each person in the company and their assigned role(s).
b) tblPersonnel has a row per person, key is 'PersonnelID' c) tblRoles is a list of all the roles in the company (administrator, clerk, shipper, truck-driver, etc.), key is 'RoleID'
d) tblPersonnelRoles is a cross-reference of all the roles assigned to each person - in simple format of:
PersonnelID | RoleID
Given all the above, I need to have a select statement that produces one row per person, and list all the fields from tblPersonnel AS WELL AS identifies each role assigned to the person.
I'm no SQL guru .. is this even possible?
I know there are alternative solutions (e.g., to write code that for each Personnel does a lookup in Roles) but for one particular situation I need a single SQL statement, or even Stored Procedure.
Thanks in advance, Rick Piovesan Detaya Corp Aurora, Ontario, Canada

I set up a connection to mysql using ADO.NET's ODBC Data Provider. And I'm running a simple query to return one table's maximum ID(int32 unsigned).But when I bind the result to a variable and excute task. It gives out error message: "An error occurred while assigning a value to variable "MaxAuditLogID": "Result binding by name "MaxID" is not supported for this connection type. " I tried to change the type of variable around but with no luck.

I have a problem figuring out how I should do the following in SQL. I have 2 tables
table 1
M_Name, M_Application A applA b applB c NULL d applD
table 2
O_Name, O_Application A applA b applXX c applC d NULL
Now I need to somehow combine this to tables where M_Name and O_name should be the where clause e.g. where M_name = O_name and the result should look something like this
Name (M_name and O_name), M_Application, O_Application A ApplA ApplA B ApplB ApplXX C NULL ApplC D ApplD NULL
I also would like to have NULLS included in the result
I have an SqlDataSource that has SelectCommand as Stored Procedure. This stored procedure returns two tables. But my SqlDataSource can see first table only. How can I see second table in Selected event of my SqlDataSource for example ? SqlDataReader has method NextResult() for this task. How in SqlDataSource ? I'm sorry for my English.

Can someone please help me figure out how I can write a select statement that returns a row from one table and the count of records from the second table using the row name from the first table?
In other words: First table has only one column "name" and that table name is called "namelist" Second table has multiple columns, and the table is called "name" so, what i want to do is something like: select name from namelist and select count(*) from [name]
Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data. When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!
I need a query to publish the front page of a blog. Each blog post needs to show BlogTitle, BlogText, PublishDate, PublishBy, Primary Image and number of comments. I would like to be able to do this in one sql statement, if possible.
The table structure is below, you can assume the first image returned from the image table is the primary image.
When I run query in excel it gives result with different column sequence. The same query gives result with different column sequence when used in query analyzer or VBA Macro. E.g., Select * from ABC.
I hope I am not asking about something that has been done before, but Ihave searched and cannot find an answer. What I am trying to do is torun a query, and then perform some logic on the rowcount and thenpossibly display the result of the query. I know it can be done withADO, but I need to do it in Query Analyzer. The query looks like this:select Varfrom DBwhere SomeCriteriaif @@Rowcount = 0select 'n/a'else if @@Rowcount = 1select -- this is the part where I need to redisplay the resultfrom the above queryelse if @@Rowcount > 1-- do something elseThe reason that I want to do it without re-running the query is that Iwant to minimize impact on the DB, and the reason that I can't useanother program is that I do not have a develpment environment where Ineed to run the queries. I would select the data into a temp table, butagain, I am concerned about impacting the DB. Any suggestions would begreatly appreciated. I am really hoping there is something as simple as@@resultset, or something to that effect.
I have a column colC in a table myTable that has a value (e.g. '0X'). The position of a non-zero character in column colC refers to the ordinal position of another column in the table myTable (in the aforementioned example, colB).
To get a column name (i.e., colA or colB) from table myTable, I can join ("ON cte.pos = cn.ORDINAL_POSITION") to INFORMATION_SCHEMA.COLUMNS for that table catalog, schema and name. But I want to show the value of what is in that column (e.g., 'ABC'), not just the name. Hoping for:
COLUMN_NAME Value ----------- ----- colB 123 colA XYZ
I've tried dynamic SQL to no success, probably not executing the concept correctly...
