Can someone tell me how to store the results of a multi-row query in a text or varchar variable so that I might do something like this:
declare @var1 text
select @var1 = {results of select date, count(*) from testtable2 group by date)
Thanks!

I'm new to sql stored procedures but I would like to store the results
of an sql statement in a variable such as:
SET @value = select max(price) from product
but this does not work, can someone tell me how I would go
about in storing the results in a variable.
@value is declared as int
Thanks in advance,

I'm working on a reporting tool that could bring back hundreds of thousands of results back at once. I need some way to run the actual query only once a day, and then the reporting tool would just pull back this cached results. To be short, I need to figure out how to do this using a minimum amount of resources. Would a DataView work with something like this? How would I have it update only once a day? I appreciate any advice!

We have some queries that are long and intensive. We have thought about running the queries and storing the data in a text file for lookup from our website.
Example: Our online store only displays items that are in stock so when a user selects a category a query runs and grabs only items that are in stock and then displays them. There could be thousands of items the query needs to sort through before displaying the items that are in stock. What if we ran this query once every hours an stored the results in a txt file? The asp page would then go to the text file to grab the results instead of having to run the query every time a user selects a category. Will this speed up the site by not having to query every time? Would this be a correct way to eliminate queries that run thousands of times a day?
thanks

Hi.
I am trying to store the column value to a variable from a distributed query.
The query is formed on the fly.
i need to accomplish something like this
declare @id int
declare @columnval varchar(50)
declare @query varchar(1024)
@Query = "select @columnval = Name from server.database.dbo.table where id ="+convert(varchar,@ID)
exec (@query)
print @Columnname

Hello all:
Here is a sample query:
DECLARE @KEYID NVARCHAR (50) ; SET @KEYID = '1074958'
DECLARE @ENTITY NVARCHAR (100); SET @ENTITY = 'HouseDimension'
DECLARE @KeyCol NVARCHAR(50);
SET @KeyCol = (SELECT LEFT(@ENTITY, (SELECT CHARINDEX( 'DIM', @ENTITY) -1)) )+ 'Key'
DECLARE @KeyValue NVARCHAR (1000)
SET @KeyValue = 'SELECT '+ @KeyCol + ' FROM HouseManagementFact WHERE HouseKey = ' + @KEYID +
' GROUP BY ' + @KeyCol + ' HAVING SUM(TotalClaimCount) > 0 OR SUM(HouseCount) > 0 '
The value resulting from Executing @KeyValue is an integer.
I want to store this value in a new variable say @VAR2
When I do this
DECLARE @VAR2 INT
SET @VAR2 = execute sp_executesql @KeyValue
its giving me an error.
can somebody let me know the correct form of storing the value resulting from @KeyValue in some variable ?
Can anyone tell me or point me in the direction of how I can store select query results to a variable in VB.NET? Im using the SqlDataSource control with dropdowns and textboxes for searching. I want to store the search results in a variable on the button click event.

Could anyone help me please,
I need a select to add the results into a variable of type string
id(int) name (varchar2)
1 a
2 b,c
3 d,e,f,g
tried wit the following:
DECLARE @variable1
SELECT @variable1 = name
FROM table
The problem with this sentece is that the only value assigned to @variable1 is the last row value, i.e.
@variable1 = "d,e,f,g"
What I need is to concatenate all values returned by the query, i.e.
@variable1 = "a,b,c,d,e,f,g"

Hi,
I'm trying to put the results from a SQL query that returns only one filed but one or more rows into a local variable in a comma separated format.
Any help is appreciated.
Thanks.
I have the following code which is incomplete. Where it says: txtVendorID = I need it to equal the results of the field VendorID from my query...here is my code. What do I need to add there?
Dim cmdSelect As SqlCommandDim intRecordIDintRecordID = Request.QueryString("RecordID")strConn = ConfigurationManager.AppSettings("conn")conn = New SqlConnection(strConn)cmdSelect = New SqlCommand("spMfgRepListAddaspxByRecordID", conn)cmdSelect.CommandType = CommandType.StoredProcedurecmdSelect.Parameters.AddWithValue("@RecordID", intRecordID)conn.Open()cmdSelect.ExecuteReader()txtVendorID.Text = conn.Close()
I am attempting to sort the results of a query executed against a table variable in descending order. The data is being inserted into the table variable as expected, however when I attempt to order the results in descending order, the results are incorrect. I have included the code as well as the result set.
DECLARE @tblCustomRange AS TABLE
(
RecordID INTEGER IDENTITY(1,1),
RangeMonth INTEGER,
RangeDay INTEGER
)
DECLARE @Month INTEGER
DECLARE @Day INTEGER
-- Initialize month and day variables.
SET @Month = 8
SET @Day = 11
-- Insert records into the table variable.
INSERT INTO @tblCustomRange
(RangeMonth, RangeDay) VALUES (1,2)
INSERT INTO @tblCustomRange
(RangeMonth, RangeDay) VALUES (1,27)
INSERT INTO @tblCustomRange
(RangeMonth, RangeDay) VALUES (6,10)
INSERT INTO @tblCustomRange
(RangeMonth, RangeDay) VALUES (9,22)
INSERT INTO @tblCustomRange
(RangeMonth, RangeDay) VALUES (12,16)
-- Select everything from the table variable ordering the results by month, day in
-- descending order
SELECT * FROM @tblCustomRange
WHERE (RangeMonth < @Month) OR
(RangeMonth = @Month AND RangeDay <= @Day)
ORDER BY RangeMonth, RangeDay DESC
I am getting the following resultset:
RecordID RangeMonth RangeDay
----------- ----------- -----------
2 1 27
1 1 2
3 6 10
I am expecting the following resultset:
RecordID RangeMonth RangeDay
----------- ----------- -----------
3 6 10
2 1 27
1 1 2
I need to manage the number of rows affected by a query.
If I run this script on my database:
SELECT COUNT(*)
FROM TABLE_NAME
WHERE TABLE_NAME.FLAG = 'I'
AND NOT EXISTS
(SELECT*
FROMERR_TABLE_NAME
WHERE ERR_TABLE_NAME.FIELD_1 = TABLE_NAME.FIELD_1
AND ERR_TABLE_NAME.FIELD_2 = TABLE_NAME.FIELD_2)
the query analyzer gives me back the number of lines affected:
-----------
4,00
(1 row(s) affected)
I need to manage this amount (4,00), so I applied this modification:
DECLARE @NUM_ROWS INT
SET @NUM_ROWS = (SELECT COUNT(*)
FROM TABLE_NAME
WHERE TABLE_NAME.FLAG = 'I'
AND NOT EXISTS
(SELECT*
FROMERR_TABLE_NAME
WHERE ERR_TABLE_NAME.FIELD_1 = TABLE_NAME.FIELD_1
AND ERR_TABLE_NAME.FIELD_2 = TABLE_NAME.FIELD_2)
)
but it doesn't work!! the SRV returns me this:
Server: Msg 107, Level 16, State 3, Line 3
The column prefix 'TABLE_NAME' does not match with a table name or alias name used in the query.
Do you know another way to store the number of rows affected?
SQL 2012R2 Std. I have a sql statement to retrieve data in XML format. I have to use EXPLICIT because I have to use tag <CDATA>
I would like to store the XML returned into 1 column containing the XML tags.
For example:
#tmpXML
row 1: <DOC><NET_INFO net_ID=34><NOTES><![CDATA[description]]></NOTES></NET_INFO></DOC>
row 2 <DOC><NET_INFO net_ID=35><NOTES><![CDATA[description2]]></NOTES></NET_INFO></DOC>
select *
into #tmpXML
FROM (SELECT 1 AS Tag
[Code] ....
But I keep getting an error message:
The FOR XML clause is invalid in views, inline functions, derived tables, and subqueries when they contain a set operator. To work around, wrap the SELECT containing a set operator using derived table syntax and apply FOR XML on top of it.
I have tried a couple of other ways but continue to get an error message.
All,
I'm trying to store the results of my store procedure in a temp table. when I try it, I got the error saying...

syntax of my code...
create table #Temp1 (ID int)
insert into #Temp1
EXEC SP1
when I try to run the above code I get the error "Insert exec cannot be nested"

I just read something interesting here: http://www.informit.com/library/content.asp?b=STY_Sql_Server_7&seqNum=101
A column type that helds an expression, and in queries returns the results.
That sounds excelent in my database, to save some code in my client applications. E.g adding price totals, and taxes of an order.
I can't find any info about this in later versions of SQL server. Is this not possible anymore?
I know this can be done, because I saw it and tried it once. But did not use it at the time and consequently forgot how.
I am storing an expression to a variable @Var Varchar(50)
@Var = ('aa','bb','cc')
I want to:
Select * from Table WHERE Field IN @Var
Substituting my variable for the " ('aa',bb','cc') which I can build dynamically...thus the use.
Purpose:
I have an aggregate query that currently has a CASE statement based on the contents of ('aa',bb','cc'). However, those contents can change. The aggregate will not allow the subquery (SELECT Field FROM Table).
What I remember looked something like:
SELECT * FROM Table WHERE field in ' & @Var &'.

View 1 Replies View RelatedHello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist.
My current SQL statement is as follows.
SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))"
So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated.
Thanks,
James.
Hello all
I have a database query which will return a single value
SELECT COUNT(DISTINCT(Level_id)) FROM RoleSkill WHERE Route_ID = 1
obviously this will return only a single value and not an array of data like most database queries, therefore i would like it to be sent directly to an integer variable.
I tried doing this directly with a sqlcommand but get error that it cannot be converted to integer. Is there a good way of solving this problem?
thanks for your help

I have an aggregate transform that outputs two columns, a group by (DT_STR) and a count(column name) (DT_UI8). The results are put into a Recordset Destination. When I attempt to map these columns to variables in a Foreach Loop Container (using a Foreach ADO Enumerator), I get the error:
Error: 0xC001F009 at ExtractNNRPersonUpdates: The type of the value being assigned to variable "User::NNRPersonCount" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
Error: 0xC001C012 at Foreach Household Loop Container: ForEach Variable Mapping number 2 to variable "User::NNRPersonCount" cannot be applied.
The variable mentioned in the error message is setup as a UInt64. I've tried all other integer data types and nothing works. I also tried changing the data type of the count coming out of the Aggregate transform but received a warning stating this isn't possible.
Any idea what I may be doing wrong?

I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT;
SET @DV = (SELECT MAX(DateValue) FROM tblTG);
DECLARE @PV INT;
SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT;
SET @DV = ?;
DECLARE @PV INT;
SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.
