Writing Query To Dynamically Select A Database Table
Sep 24, 2006
Is there a way I can write a query to dynamically select a database table. That is, instead of having a variable for a certain column like customerId which would be €ścustomerID = @customerID€? I want to use the variable to select the table. I assume I may have to use a stored procedure but I am unclear as to how this would be coded.
Thanks

All- I would greatly appreciate some assistance in creating a SELECT statement for table headcount in the following problem:
First, find the schema here: http://home.pacbell.net/eulimi/schema_headcount.GIF
The problem:
Given a person_id (a record in the person table), list all headcount records WHERE:1) headcount.person_id = person.person_id AND2) the headcount.act_session_id belongs to a activity (from the activity_session table) that the person is allowed to attend by virture of the person's membership in a subexpedition.
Note that:
- A person can be a member of one or more circles (via the circle_person table)- Each circle belongs to exactly one subexpedition.- A persons who is a member of a subexpedition (via one or more circles) is entitled to sign up for one or more activities (activity_sessions) associated with the subexpedition.
So, put yet another way, the SELECT command should show, for a given person_id, the list of records in headcount that includes the activities (act_session_id) that the person is entitled to join by virtue of the persons membership in the subexpedition via his circle. (Whew!)
I hope this is enough information. I think the problem would be fun if I knew what I was doing. (SQL newbie here.) I suspect I need several INNER JOINs and a compound WHERE clause.
Thanks in advance!!!

I have written several scripts to pull in nested info to the analyzer window. How do I get this data to write to the new table I have created in the database? here is the current script:
select Hierarchy_List.Hierarchy_Label as Hierarchy_Name,
Hierarchy_List.hierarchy_ID as Hierarchy_ID,
Hierarchy_List.Parent_ID as Parent_ID,
frequency_item.manufacturer as Motor_Make,
frequency_item.model as Frame
from hierarchy_list full outer join Frequency_item
ON HIERARCHY_LIST.HIERARCHY_ID = frequency_item.HIERARCHY_ID
where parent_id in (select hierarchy_id from hierarchy_list where parent_id in
(select hierarchy_id from hierarchy_list where parent_id in
(select hierarchy_id from hierarchy_list where parent_id in
(select hierarchy_id from hierarchy_list where parent_id=0)
and parent_id<>0) and parent_id<>0) and parent_id<>0)
and parent_id<>0 and frequency_item.description = 'motor'
I need to move this data to the VAER.Al_Machines and the column names are the same. I can move data via DTS, but it won't work on this because the nested info. Is there a script addendum I can add to this to execute both the search and the transfer in one job so I can automate it? Thanks for any help.

I am building a dashboard features that allows user to select reports from a dropdownlist. It is pulling from a table called Reports (cols: ReportID, Description, sqlView) In this Report table the report is associated to a view that queries the report.
And the user's selections are stored in table called UserReport (cols: userID, ReportID, createDt) .
I need to get a Dataset to contain datables of all reports selected. (for example a user select 3 reports, the dataset should contain 3 datables that represent the report).
I want to accomplish this by create a store procedure that queries the Reports table and then dynamically executes the views that related to the user selected reports. Can anyone give me an example on how to create the storeprocedure?
Thanks,
CG

writing a cross join query with one table:
Cities(City_name, X_coordinate, Y_coordinate)
the result should be all combinations without reverse column returns
SELECT * FROM [dbo].[Cities] as P1
Cross JOIN [dbo].[cities] as p2
where (p1.City_name != p2.City_name) and ???
for example if there are three Cities as A,B,C the result should be: A->B, A->C, B->C (without the returns B->A, C->A, C->B)

Hello,
I am not sure if this possible, but I have store procedures that access to multiple databases, therefore I currently have to hardcode my database name in the queries. The problem start when I move my store procedures into the production, and the database name in production is different. I have to go through all my store procedures and rename the DBname. I am just wonder if there is way that I could define my database name as a global variable and then use that variable as my DB name instead of hardcode them?
something like
Declare @MyDatabaseName varchar(30)
set @MyDatabaseName = "MyDB"
SELECT * from MyDatabaseName.dbo.MyTable
Any suggestion? Please.
Thanks in advance

I have the folowing databases DB1,DB2,DB3,D4,DB5........
I have to loop through each of the databases and find out if the database has a tablename with the word 'Documents'( like 'tbdocuments' or 'tbemployeedocuments' and so on......)
If the tablename having the word 'Documents' is found in that database i have to add a column named 'IsValid varchar(100)' against that table in that database and there can be more than 1 'Documents' table in a database.
can someone show me the script to do it?

Hello,
I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post.
I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table.
This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off.
So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining?
Thanks in advance,
Andy

I have set up a 'Parameters' table that solely stores all pre-assigned selection values for a webform. I customized a stored query to Select the values from the Parameters table. I set up the webform. The result is that the form1.apsx automatically populates each DropDownList task with the pre-assigned values from the 'Parameters' table (for example, the stored values in the 'Parameters' table 'Home', 'Business', and 'Other' populate the drop down list for 'Type').
The programming to move the selected data from form1.aspx to a new table in the SQL database perplexes me. If possible, I would like to use the form1.aspx to Postback (or Insert) the "selected" data to a *new* column in a *new* table (such as writing the data to the 'CustomerType' column in the 'Customers' table; I clearly do not want to write back to the 'Parameters' table). Any help to get over this hurdle would be deeply appreciated.

Hey all. I'm trying to create a stored proc that will update a variable column, depending on the parameter I pass it. Here's the stored proc:
CREATE PROCEDURE VoteStoredProc
(
@PlayerID int,
@VoteID int,
@BootNumber nvarchar(50)
)
AS
DECLARE @SQLStatement varchar(255)
SET @SQLStatement = 'UPDATE myTable SET '+ @BootNumber+'='+ @VoteID + ' WHERE (PlayerID = '+ @PlayerID +')'
EXEC(@SQLStatement)
GO
I get the following error:
Syntax error converting the nvarchar value 'UPDATE myTable SET Boot3=' to a column of data type int
The update statement is good, because if I use the stored proc below (hard-coded the column), it works fine.
CREATE PROCEDURE VoteStoredProc
(
@PlayerID int,
@VoteID int,
@BootNumber nvarchar(50)
)
AS
UPDATE
myTable
SET
Boot3 = @VoteID
WHERE
PlayerID = @PlayerID
GO
Is there a way to dynamically choose a column/field to select from? Or is my syntax incorrect..?
Thanks!

For each customer, I want to add all of their telephone numbers to a different column. That is, multiple columns (depending on the number of telephone numbers) for each customer/row. How can I achieve that?
I want my output to be
CUSTOMER ID, FIRST NAME, LAST NAME, TEL1, TEL2, TEL3, ... etc
Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.
I want to do it using SELECT. Is it possible?

The below code is ASP 1.0 to dynamically search a database and I want to use the same concept for a ASP.Net 2.0 solution. Do I do this in the code behind or on the aspx page and if on the aspx page what controls do I use for the array split? Basically where do I start. It took me a long time to get this old code working, I am hoping it is simpler in 2.0.
Thank you

Hello,
I m writing a stored procedure to query a table Population that has the following fields - CityId, CityName, Plus0, Plus10, Plus20, Plus30, Plus40, Plus50, Plus60, Plus70, Plus80. The field Plus0 contains the number of people of age > 0 living in the city, Plus10 contains the number of people of age > 10 living in the city and so on. Given the city id and age groups like 20To40, 50To60, 40Plus, etc., I should be able to query the number of people in the city corresponding to the requested age group. Note that if the requested age group was 20To60, I need to make use of only 2 fields Plus20 and Plus60 in the table to compute this value. And if the requested age group was 40Plus, then I need only the value in the field Plus40. The problem is that a wide variety of age groups can be requested like 0Plus, 10Plus, ... , 80Plus, 0To10, 0To20, 0To30, .... 70To80.
Which is the most effecient way to handle this ?
1. Have a stored procedure that returns all the fields even though only 1 or 2 of them would be actually used ?
In this case, if I returned data for a large number of cities then there would be a lot of unnecessary information that was returned by the query. Lots of data would be passed through the network though most of it would not be used.
2. Have a stored procedure that takes in parameters @Plus0, @Plus10, @Plus20, .. @Plus80 that are bits indicating whether the field was required or not and then using a CASE statement to return values for a field only if the corresponding bit parameter was set, and returning NULL if the corresponding bit paramter was not set ?
In this case, I would be returning NULL for all those fields that were not required for a particular age group. This would save some network bandwidth, wouldn't it ?
3. Pass in the age group itself (ex: 0To20) as a parameter to the stored procedure and have lots of IF statements, one for each age group, that return only the fields that are needed for that age group.
This leads to a lot of code repitition.
4. Use a similar approach as above but use dynamic SQL queries to avoid code repitition.
But using dynamic SQL queries can affect the performance of the stored procedure as they need to be compiled each time.
5. Any other possible approaches ??
Looking forward to your responses,
Thanks much,
bmgun.

I have a remote report ...
I need to call one of two stored procedures depending on which parameters were passed to the report. (Both stored procedures return the same fields.)
Does SQL Reporting Services allow you to switch the dataset or stored procedure name dynamically? If so, where do I put the logic? Right now I have it working with one stored procedure.
I'm thinking that I should just make one stored procedure that takes all parameters and calls one of the other two stored procedures. Do I have any options besides this?
Thanks in advance!

Hi Friends,
I need help on writing an optimized query for the following problem..
Consider a table with columns "Date Emp1 Emp2"
Date Emp1 Emp2
1-feb 1 . . 2
2-feb 3 . . 4
3-feb 6 . . 1
4-feb 1 . . 2
5-feb 1 . . 5
6-Feb 5 . . 7
Now, I want search for records with employee id 1 in a way that if column emp1 contains 1 then I want the data in column emp2, and if column emp2 contains 1, then I want data in column emp1.
The output has to be a single column with no duplicate values. In the above example, for employee id 1, the output would be, 2,5 and 6 only.
This table has lakhs of records. I have to scan both columns for a given employee id. What will be the most optimized way to retrieve the data faster. Also, do I need to restructure this table for faster data retrieval?
I have indexes on emp1 and emp2 columns. Do we need union here and if yes, what is the best optimized query for the same?
