How To Retrieve Two Columns From Different Tables As A Single Result Set
May 16, 2008
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.

I need to retrieve columns names(instead of select * from) as single row from table in dynamic way.
i m using following query.
its working fine while using from selected database. but its not working when i m running from different database.
DECLARE @columnnames varchar(max)
select @columnnames = COALESCE(@columnnames,'')+column_name+',' from INFORMATION_SCHEMA.COLUMNS(nolock)
where table_name='table_20141224'
select @columnnames
I need to pass database name dynamically like using by variable.
Is this possible to use variable after from clause. or any other methods?
eg:
DECLARE @columnnames varchar(max)
DECLARE @variable='db_month11_2014'
select @columnnames = COALESCE(@columnnames,'')+column_name+',' from @VARIABLE.INFORMATION_SCHEMA.COLUMNS(nolock)
where table_name='table_20141224'
select @columnnames

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?

Till recently we were using the following code to retreive schema information of columns of tables
Dim schemaTable = connection.GetOleDbSchemaTable( _
System.Data.OleDb.OleDbSchemaGuid.Columns, _
New Object() {Nothing, Nothing, tableName, Nothing})
Now instead of getting the name of table (which i was using as param for filtering) i'm going to receive a sql-query. Now my question is if I were to get a query like the following :
SELECT
[EmployeeID],
[Title] + ' ' + [LastName] + ' ' + [FirstName] AS FullName,
[BirthDate],
[Address],
[City] + ', ' + [Region] + ', ' + [Country] + ' - ' + [PostalCode] AS FullAddress
FROM [dbo].[Employees]
Then how can I retrieve the schema information of only the columns present in the query.
(Its possible that i might get a query with multiple tables with joints)...

I want to select columns from different tables into a single table...Not sure if a temp table is suited for this and if so how I should implement it (NOTE: this query will be executed many times by different users at the same time, so I'd rather avoid temp tables!)I have:TABLE1idfirstnamedescriptioncreatedateTABLE2idcarnamespecificationsimportdateNow, I want a resultset that has the columns (columns from other tables from which the values should be retreived are behind the desired columns):id (TABLE1.id, TABLE2.id)title (TABLE1.firstname , TABLE2.carname)description (TABLE1.description , TABLE2.sepcifications)date (TABLE1.createdate , TABLE2.importdate)Thanks!

I am using SQL Server 2005.
I have a table with records like this:
Date EmpID ADCode ADAmount
----------------------------------------------------------------------
01-Jul-07 101 GPF 150
01-Jul-07 102 GPF.ADV 100
01-Jul-07 103 GPF 250
01-Jul-07 103 GPF.ADV 200
01-jul-07 104 GPF 300
I want to show results like this using a single SQL query:
Date EmpID GPF GPF.ADV
-----------------------------------------------------------
01-Jul-07 101 150 0
01-Jul-07 102 0 100
01-Jul-07 103 250 200
01-Jul-07 104 300 0
I tried:
select PaySlipDate,EmpID,
case ADCode when 'GPF' then ADAmount else 0 end GPF,
case ADCode when 'GPF.ADV' then ADAmount else 0 end 'GPF.ADV'
from EmpSalaryRecord
It is showing like this:
Date EmpID GPF GPF.ADV
-----------------------------------------
01-Jul-07 101 0 0
01-Jul-07 101 150 0
01-Jul-07 102 0 100
01-Jul-07 103 0 0
01-Jul-07 103 250 0
01-Jul-07 103 0 200
It is showing multiple records of each employee for each date. First a record with GPF and GPF.ADV both zero and then records with values. I want a single record for each date and employee.

Hi All: I'm just trying to migrate from vbScript to .net and am trying to retrieve a single value from a dB based on a value passed in a form. I can't seem to find the right tutorial to explain this to me, and am open RTFL'ing any links!
What I have thus far is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim strConn As String = "server=myServer;uid=myUID;pwd=myPWD;database=myDB"
Dim myQuery As String = "Select myVal FROM myTable WHERE myID= " & lbmyID.SelectedValue
Dim myConn As New SqlConnection(strConn)
Dim myObj As SqlDataReader
Dim cmd As New SqlCommand(myQuery, myConn)
myConn.Open()
myObj = cmd.ExecuteReader(System.Data.CommandBehavior.SingleRow)
Dim myReturnedValue As String = myObj.....
myConn.Close()
end sub
I feel like I'm close, but I'm stuck on how to get the value returned by the query into "myReturnedValue"...if this is the wrong approach please let me know!

We have a sort of complex user structure in the sense that depending on the type of user the data resides in different tables. Therefor I needed a stored procedure that finds out what table to look for a certain column in. Below is such a stored procedure and it works like it should but my problem is that I don't know how to retrieve the result (which should be a string so can't use RETURN).
I've tried using an OUTPUT variable but since I just run EXEC (@statement) in the end I can't really set an output variable the common way (as in EXEC @outputVariable = PMC_User_GetUserValue(arg1, arg2..)) or can I?
I have also tried to use SELECT to catch the result somehow but no luck and Google didn't help either so now I'm hoping for one of you... Notice that you don't have to bother about much of the code except for the end of it where I want it to return somehow or figure out a way to call this stored procedure and retrieve the result.
Thanks in advance

Hello,
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)
Any suggestions?
TIA

Hi everyone,
On daily basis I need to generate excerpts by mean of Excel. Prior to sql25k I used to play with Enterprise Manager and pick up the name of all the columns for a table very easily doing this
select top 1 f1,f2,-.. from table
name age
enric 80
How do I such thing from Sql Management Studio??
It's a silly thing, I know, but it's very useful for me because when I've got those columns then I can do paste them perfectly into .XLS.
Otherwise I see forced to write one by one and sometimes tables have more than 60 columns
It's not useful generate a CREATE TABLE script or launch SP_HELP <MYTABLE> because I obtain the name of the columns in vertical no horizontal.
Thanks a lot!!!

Hello all. I need to extract the column names that form the primary key group on a table in SQL Server. I have a table called Account and it contains ten columns. The primary key consists of two columns - MasterAccountID, AccountID. This primary key is a unique constraint and is clustered (it acts as an index as well as a primary key group). I have tried the following to no avail:exec sp_pkeys Account -> returns no rowsexec sp_helpindex Account -> throws an error stating that the object 'Account' does not existIf I run the following SQL statement, I can see all of the PK_* constraints in the database, so I know they are there:select * from information_schema.table_constraintswhere constraInt_type IN ('PRIMARY KEY','FOREIGN KEY') Again, I need to be able to specify a table name and have it return the columns (don't care if it returns extra fields) that make up the primary key fields for that table. Thanks!

I have the following table
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,

So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.

Hi,
SQL Server 2005 has a new very useful feature for creating non-clustered indexes called INCLUDE <columns> which are very helpful when trying to create covering indexes.
Does anyone know of a way to retrieve these INCLUDE columns through any of the system metadata tables? The sp_helpIndex stored procedure is what I currently use but that only returns the (sorted) index columns and not the include columns.
Thanks in advance,

I am using Query Writer (should be SQL 2005) and have included the following code.
The end result: -should retrieve columns and display the count for two different data sources that were added by personnel in a specific department.
Problem: results are returned but not accurate. The code below works just fine and returns the results for all spot buy orders added by personnel in the sales department. However, I want to add a column in the same report that also counts blanket orders from the exact same table added by personnel in the sales department. The database uses views (v) in lieu of dbo.
Parameters:
@Add_Date_From SMALLDATETIME='',
@Add_Date_To SMALLDATETIME='',
@Last_name VARCHAR(50)='',
@First_Name VARCHAR(50)=''
Query:
SELECT
T1.Last_name,
T1.First_name,
T2.Position,
T3.Add_date,
COUNT(T4.PO_Type) AS 'Spot Buy Added'
[Code] ....
If I substitute COUNT(T4.PO_Type) AS 'Spot Buy Added' with COUNT(T4.PO_Type) AS 'Blanket Added' I also get accurate results for the blanket order. IE separately they work just fine. If I try to combine the two that is where the trouble begins.
What am I doing incorrectly when I try to add the criteria/code for the additional column to count the blanket orders?
