I am writing a stored procedure in which I have a query that selects the Headings of Columns from another table...
I want to then create a loop that will contain a variable with the value of the column heading and then set the column to a value of NULL...
Is there any way to accomplish this???
I thought about placing these values into a temp table...
This is what I have so far...
Declare @QueryX nvarchar(500)
Declare @FieldName varchar(20)
Create Table #UpdateRejDoc
(
Abbreviation varchar(20)
)
Insert into #UpdateRejDoc
Select Abbreviation
From tbl_Titles
left JOIN tbl_TitleRouting on tbl_Titles.Title_ID = tbl_TitleRouting.Title_ID
Where tbl_TitleRouting.Application_ID = @Application_ID
While Exists (Select Abbreviation from #UpdateRejDoc)
Begin
Set @QueryX = 'Update DBLandfillUser.tbl_ObjectApprovals' +
'@AppName + Set @FieldName = null Where object_id =' + Cast(@object_id as VarChar(20))
End
I have a quick question on SQL Server. Lets say I have table Order which has column names OrderId, CustomerName, OrderDate and NumberofItems. To select the OrderID values from the table I say
Select OrderId from Order.
But in the select if I want the column name to be variable how do I do it. I tried the following code through a stored procedure.
declare @order_id nvarchar(10)
select @order_id = 'OrderID'
SELECT @order_id from Order.
The code above gave me the string "OrderID" as many times as there were rows in the table but I could never get the actuall values in the OrderId column. Can you please send me some ideas or code where I can get values from the column names and at the same time change the column name dynamically.
I do a SELECT * from table command in an ASP page to build a text fileout on our server, but the export is not to allow a field name rows ofrecords.

View 1 Replies View RelatedIs there a SELECT statement that will return a the column names of a given table?
View 5 Replies View RelatedI would like to provide the names of columns in an insert statement from a schema table, so that when running through a number of Bus Rule checks I can reference the schema table and only maintain the columns in the schema table rather than maintain named columns in multiple insert statements. So my query for one check looks like below. I'm using dynamic sql to execute the insert statement. My question is, is there a better way or different way to do this without using dynamic sql? Ie, Is there a way that I can use the columns parameter like this instead?
Insert
('+@columns+',KickoutID) Values('+@columns+',1);
Dynamic code:
Declare @columns as nvarchar(max);
Declare @InvSQL as nvarchar(max);
SELECT @columns =
STUFF ((
SELECT ', [' + name + ']'
FROM syscolumns WHERE id = OBJECT_ID('dbo.table_pvt')

View 3 Replies View RelatedHello everyone,
I'm still quite new ASP.net, Visual Web Developer 2008, and SQL. It has been a fun learning experience so far. Anyways, the site I am designing needs to allow its users to extensively search several different databases (MS SQL databases). I have followed many of the tutorials and have found it rather easy to add table adapters, gridviews and other data features that use basic SQL Select statements. One of the major database tables contains several columns which I would like to include as a search parameters from a drop down list. I was wondering if there is any way I can write a select which will pass a variable to be used as a column name to the statement? For example:
SELECT DATE, GAME, EXACT, @COLNAMEFROM HistoryWHERE @COLNAME = @SOMEVARIABLE
This obviously doesnt work, but thats the gist of what I want to do. Any suggestions? I need this to be simple as possible, Most everything I'm doing is done through the visual design mode. Im still slow to learn C# and apply it in the codebehind files unless I have very detailed step by step instuctions.
Thanks

How do I use a variable to specify the column name in a select statement?
declare @columnName <type>
set @columnName='ID'
select @columnName from Table1
Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized?
SET NOCOUNT ON
Declare @RandomRecordCount as int, @Counter as int
Select @RandomRecordCount = 1000
Declare @Type table (Name nvarchar(200) NOT NULL)
Declare @Source table (Name nvarchar(200) NOT NULL)
Declare @Users table (Name nvarchar(200) NOT NULL)
Declare @NumericBase table (Number int not null)
Set @Counter = 0
while @Counter < @RandomRecordCount
begin
Insert into @NumericBase(Number)Values(@Counter)
set @Counter = @Counter + 1
end
Insert into @Type(Name)
Select 'Type: Buick' UNION ALL
Select 'Type: Cadillac' UNION ALL
Select 'Type: Chevrolet' UNION ALL
Select 'Type: GMC'
Insert into @Source(Name)
Select 'Source: Japan' UNION ALL
Select 'Source: China' UNION ALL
Select 'Source: Spain' UNION ALL
Select 'Source: India' UNION ALL
Select 'Source: USA'
Insert into @Users(Name)
Select 'keith' UNION ALL
Select 'kevin' UNION ALL
Select 'chris' UNION ALL
Select 'chad' UNION ALL
Select 'brian'
select
1 ProviderId, -- static value
'' Identifier,
'' ClassificationCode,
(select TOP 1 Name from @Source order by newid()) Source,
(select TOP 1 Name from @Type order by newid()) Type
from @NumericBase
SET NOCOUNT OFF
How do I pass a single column of values from a successful merge join to an EXECUTE SQL statement so it can be used with an "IN" criteria of the WHERE clause? Here's an example of my update statement with two random key values:
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK IN ("XYZ123", "DEF890")
Is this even possible in SSIS, or am I better off using a loop and running the update EXECUTE SQL Statement for each individual key value, as in the following example?
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "XYZ123"
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "DEF890"
Hi
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.
Thanks.
I'm looking for a way to refer to a package variable within any
Transact-SQL code included in either an Execute SQL or Execute T-SQL
task. If this can be done, I need to know the technique to use -
whether it's something similar to a parameter placeholder question
mark or something else.
FYI - I've been able to successfully execute Transact-SQL statements
within the Execute SQL task, so I don't think the Execute T-SQL task
is even necessary for this purpose.
Can I do something like the following with SQL Server?
DECLARE @Table_Name varchar(100)
SET @Table_Name = 'Accounts'
SELECT * FROM @Table_Name
Hi,
I have an Execute SQL Task (OLE DB Connnection Manager) with a SQL script in it. In this script I use several SQL variables (@my_variable). I would like to assign an IS variable ([User::My_Variable]) to one of my SQL variables on this script. Example:
DECLARE @my_variable int
, <several_others>
SET @my_variable = ?
<do_some_stuff>
Of course, I also set up the parameter mapping.
However, it seems this is not possible. Assigning a variable using a ? only seems to work in simple T-SQL statements.
I have several reasons for wanting to do this:
- the script uses several variables, several times. Not all SQL variables are assigned via IS variables.
- For reading and mainenance purposes, I prefer to pass the variable only once. Otherwise every time the script changes u need to keep track of all questionmarks and their order.
- Passing the variable once also makes it easier to design the script outside IS using Management Studio.
- This script only does preparation for the actual ETL, so I prefer to keep it in one task instead of taking it apart to several consecutive Execute SQL Tasks.
- I prefer to use the OLE DB connection manager because it's a de facto standard here.
Could anyone help me out with the following questions:
- Is the above possible?
- If so, how?
- If not, why not?
- If not, what would be the best way around this problem?
Thanx in advance,
Pipo

I am attempting to export data on a daily basis via DTS to an XLspreadsheet. I would either like to: a) have a separate worksheet inthe spreadsheet for each export or b) a completely differentspreadsheet for each export. Whenever I attempt to use a variable asthe name of my table in the DTS package, it will not let me.Constructing a string and attempting to execute it also fails,although both of these work in query analyzer. Any advice?Peter
View 1 Replies View RelatedGreetings!I am now doing one type of analysis every month, and wanted to creattable names in a more efficient way.Here is what happens now, everytime I do the analysis, I will create atable called something like customer_20050930, and then update thetable by using several update steps. Then next month I will create atable called customer_20051031. Does anyone know if there is a betterway to do it? like using a macro variable for the month-end date? Noweverytime I have to change the table name in every single update step,which would cause errors if I forget to change one of them. By using amacro, I would only need to change it once.Thanks!

and psss only 1 Variable name to the second stored PROCEDURE
like this i don't get this error
The variable name '@Start_Date' has already been declared. Variable names must be unique within a query batch or stored procedure.
Msg 134, Level 15, State 1, Line 146
The variable name '@End_Date' has already been declared. Variable names must be unique within a query batch or stored procedure.

Is there anyway to determine what the resulting Field Names are going to be from a SQL Statement?
For example:
SELECT TABLE1.FIELD1, TABLE1.FIELD2, TABLE1.FIELD3, TABLE2.FIELD1 AS ANOTHERNAME
FROM TABLE1 INNER JOIN TABLE2 ON TABLE1.PK = TABLE2.FK
resulting field names:
FIELD1
FIELD2
FIELD3
ANOTHERNAME
Seems easy enough splitting all values before "FROM" by comma and doing some manipulation to remove table names and anything before the word "AS". However, it gets more difficult when you have complex CASE statements embedded in you query that may also contain commas.
Just a shot in the dark because I don't know if anyone has already done something like this before.
Thank you in advance,
Jeff
Ok I am faced with working with XML on a regular basis, which is fine.
DECLARE @ViewSN INT
IF NOT EXISTS (select null from tblviews where viewcode = 'loadAtTerm') --<workflowEventType>loadAtTerminal</workflowEventType>
insert into tblviews (ViewName,Description,OutBoundForm,StoredProcSN,TriggersReply,ViewCode,DispXactLayer,DispXactViewType,DispXfcTag,Comments)
select 'QC:WF-LoadAtTerminal','This View Corresponds to the XML for loadAtTerminal in Omnitracs Workflow','0',NULL,'0', 'loadAtTerm','MCOM','MCOM',NULL,NULL
[code]...
What would be really useful is to be able to present any xml file and automatically parse the NODE names into a memory variable table and then the fields of each node in another.
Hey all,
I trying to figure out if you can get a list of table names from a particular database by writing a single SQL statement.
E.G. In Oracle, from SQLPlus - you can say:
Select table_name from user_tables;
Is there anything like that SQL that I could run from Query Analyser to get a list of table names from a particular SQL Server database?
Thanks in advance,
Tommy

I have a variable SYear with the data type Integer and the value 2005.
Connection type is OLE DB, and my sql statement is:
DECLARE @MyYear Int
SET @MyYear = ?
I have set the variable User::Syear as Input with the parameter name=0, there is no result set. I set BypassPrepare both True and False. However, this simple statement does not work. I keep having an error. If I put integer value directly into @MyYear, it is fine. What is wrong in here? Somebody help me!
