Variable In Sql Satement Not Working - Hard Coding Does Work
Jan 10, 2008
I have a variable that is created dynamically that will be used as an input for a sql statement.
When I display the variable in a text box it looks like this:
(PROP_CLASS IN ('" & 100 & "','" & 101 & "' ))
The following works when I hard code the values into the SQL statement:
strSQL = "SELECT * FROM web_transfer WHERE (PROP_CLASS IN ('" & 100 & "','" & 101 & "' )) AND ........."But I get no values returned when I use the variable directly in the sql: strSQL = "SELECT * FROM web_transfer WHERE (PROP_CLASS IN (" & propertyClass & ")) AND ..........." The propertyClass variable is the text string “(PROP_CLASS IN ('" & 100 & "','" & 101 & "' ))“. How do I add this variable to the sql string so that it is recognized. I guess that it is adding some hidden characters. Any help please?? I am a newbie to this, s

See DDL and sample data below. What would be the easiest way to get the desired output without hard coding the values? Data in both tables may change over time.
DECLARE @num AS TABLE (
Id INT IDENTITY(1, 1)
,Price MONEY
)
DECLARE @range AS TABLE (
Id INT IDENTITY(1, 1)
,Rng MONEY
[code]....

Hi all,We're selecting data from our database, FirstName, LastName, MobileNumber etc.We're using the detaials view function to return it in a table upon selection. However all of the variables are returned as they are in the database, ie: without spaces. We tried putting in spaces by selecting "AS what ever", but MSSQL does not seem to like spaces.Any ideas?Thanks

Hi there,
The postage and packing scheme being used at the site I'm working on depends on the customer's location.
If they're in the UK they get once scheme and if they're in Ireland they get another. Furthermore, if they're anywhere else they get another scheme.
A customer's country is indicated by a 'countryID' stored in the main customer row in the database. (This ID references a country in the Countries table.)
Thus, I was wondering if it is acceptable to hard code the country pk of the UK and Ireland into the formular which works out the postage and packing?
At present, for a similar issue, I've even hard coded the the pk of UK and Ireland into some Javascript running at the client.
Is it fair design to work with a hard coded pk like this?
Cheers,

I got a report that seems to be limiting its displayed data to the first 8 records but not in the SQL statement itself. Although I have been working with SQL for many years I'm very new to Reporting Services so it may be something very simple, like perhaps a property that can be changed on the report for me to increase the amount of records the report is pulling from the database?
I don't seem to find any property set to 8 though.
Also the report is not pulling the records in the order the query pulls them, but in an apparent random order, I don't need to change this but it may help describe the report a bit better.

I have not been able to find the answer as to why the LEFT() function doesn't see the variable as being a variable.
I originally thought it did not accept a variable as the first parameter, however the definition says it can be a variable.
Anyone knows why this isn't working?
This is how I have the code:
SELECT LEFT(@tpatdata, CHARINDEX('^', Alert1) -1)
the variable @tpatdata is the column name (tablename.Alert1), iif I rewrite it like this:
SELECT LEFT(tablename.Alert1, CHARINDEX('^', Alert1) -1) it works.

I am trying to setup a query that receives input variables one being a number which could be null (could receive as string).
What I want to happen is if a number is sent the data is filtered by that number but if it is empty no filtering is performed I think this involves using a case statement in a where clause but can't work out the syntax I am using sql 200 server.
I think the case statement is something like this:
(week_no = CASE @week WHEN null THEN '#' ELSE @week END)
or maybe I am way off
I considered using like @inNumber + '%' but this would cause the problem of if I inoput 2 it would also return 20's 200's ...

How is the best way to check for No rows returned from a Select statement in a Stored Proc? I have see this:
Code Snippet
Declare @res int
set @res = NULL
Select @res = dbKeyColumn
From aTable
If @res is null
then no rows returned.
Surely there is a better way??

Hello to all,
I hope that somebody can help me.
I have written a sql query to search Partner. I have a wtcomValidRelationships Table. There are two Fields (IDMember(type: Int) and RelationshipIDs(type: varchar(1000)) in this table.
Example: 3418 has 3422 RelationshipID and 3422 has 4088 RelationshipID, if i want to check if there is a relationship between 3418 and 4088.
declare @IDM int;
declare @IDO char(100);
set @IDM = 3418;
set @IDO = '4088';
select B.IDMember
from wtcomValidRelationships as A, wtcomValidRelationships as B
where A.IDMember = @IDM and charindex(cast(B.IDMember as char(100)),A.RelationshipIDS) > 0
and charindex(@IDO,B.RelationshipIDs) > 0
Using this query i get nothing.
I try to use constant in charindex and i get result.
declare @IDM int;
declare @IDO char(100);
set @IDM = 3418;
set @IDO = '4088';
select B.IDMember
from wtcomValidRelationships as A, wtcomValidRelationships as B
where A.IDMember = @IDM and charindex('3422',A.RelationshipIDS) > 0
and charindex('4088',B.RelationshipIDs) > 0
So i think that charindex doesn't work with variable. But I must use variable. Can someone help me? What should i do ?
Thanks
Best Regards

I would like to run a simple select statement that pulls records from a table and returns a dataset. It is a dataset of teams. Then I want to populate a highly customized table with that dataset. The table will be a tournament bracket full of teams. Can I do something like this or do I have to display the dataset in a datagrid? Oh and this is a webmatrix project using MSDE. Anybody have any suggestions?

Hello,
I am trying to get the count of records in a file in a single round trip to the server. I tried T-SQL code similar to below and used SQLBindColumn to bind to argument #1. The code executes without error, but the result is never returned.
Any ideas what I am doing wrong?
Thanks!

I am writing some functions that work on a time series database of prices, ie volatility, correlation. I need to use the SELECT TOP syntax, but cannot do this with a variable, ie 'SELECT @x TOP * from prices'. My solution is to simply have a function for each potential period that will be looked at - 30day_volatility, 60day_volatility, etc. I looked at setting the ROWCOUNT variable but this is not allowed in functions. I haven't posted any DDL because I think the question is general enough - How do I return n ordered rows from a function without using SELECT TOP, or is there a way to use SELECT TOP with a variable that I am not aware of.
Thanks!

Hi,
I have an Execute Process Task that calls a batch file.
I need to pass in a date value to the batch file.
If I enter the value 20071018 in the "Arguments" section, it works fine.
However, I use the "Standard Input Variable", User::MyDate (which gets assigned in a previous Execute SQL Task), it bombs. The query I am using returns the date back in the format yyyymmdd. It gets assigned to a string variable, called MyDate.
e.g.)
SELECT TOP 1 CONVERT(VARCHAR, MyDate, 112) AS MyDate
FROM myTable
which result is mapped to User::MyDate
Is there any obvious reason why this doesn't work?
Thanks

Has someone managed to pass successfully a variable from a parent package to a child package? I€™ve tried a zillion permutations and I can€™t get it to work. The strange thing was that I was able to successfully do this with pre-RTM builds. Basically, what I am trying to do is:
The parent package has a variable, e.g. ExecutionID which I set using a script to System::ExecutionInstanceGUID. I verified that the variable is set correctly by dumping it to a SQL Server table.
I created a child package variable with the same name.
In the child package, I€™ve created a parent package configuration that points to the ExecutionID variable.
I am trying to read the variable in a Derived Column Task in which I have a column linked to @ExecutionID.
This doesn€™t work. Step-by-step instructions from someone who managed to concur this will be greatly appreciated.
Oh, I didn€™t have any luck hitting a breakpoint in a script task inside a child package with both in and out of process execution also.

I'm attempting to copy data from an Epicore server with multiple company
databases to another server. All this data will be placed in a single
table on the receiving server with the addition of an database identifier,
so that the receiving department will know, to which company the data
belongs. I have code that will dynamically create the SQL and then
execute it using EXEC (@SQL), and this works just fine acrosss multiple
databases. I've read in my Transact-SQL Programming book that using
EXEC() is not limited to 255 characters, but it still appears that my
dynamically created SQL is being shortened. The insert statement and the
select statement list each column, and here is that code:

Hello,
I have the following code and it seems that it is not comparing the request_close_date. What I want to do is compare the request_close_date between two tables and if it is less than the date from the TEAM3B_PULL_TOTAL_TST then insert the data into RDD_UPDATE_TST. Any help will be appreciated. It also needs to insert data into RDD_UPDATE_TST if a request exists in REQUEST_BUS_REQ and BUS_REQ_DESCRIPTION. I think that I have that coded correctly but I am not certain.
Thanks in advance,
Anne
begin
Insert into RDD_UPDATE_TST(request,business_req_id,test_case_i d,test_case_descr,request_close_date)
select distinct request,business_req_id,test_case_id,test_case as test_case_descr,request_close_date
from TEAM3B_PULL_TOTAL_TST A
where not exists (select * from BUS_REQ_DESCRIPTION_TST B where A.REQUEST = B.REQUEST)
and not exists (select * from REQUEST_BUS_REQ_TST C where A.REQUEST = C.REQUEST)
and not exists (select * from RDD_UPDATE_TST D where A.REQUEST = D.REQUEST)
and exists (select * from RDD_UPDATE_TST where REQUEST_CLOSE_DATE <>B.REQUEST_CLOSE_DATE)

Hello,
I'm coding a stored procedure. I am creating a search function where I search multiple resultsets of data. I'm getting stuck on one part of the query, and I don't know what the best option is. Basically the query looks like this:
select * from Table where ...
and Official in (... problem area ...)
What I want is if the parameter passed in is null, return all of the valid values from the table that references this field (for example, if null is passed in, I want to pass in 'T', 'F', etc.). If the value is there, I want to pass in the value. I've been stuck on this and can't figure it out.
Any ideas? I don't want to use a dynamic query. Thanks,
Brian

Hey it's not often the blindman asks for advice on sql coding (never, I think), so here is an opportunity to solve a problem I've been knocking my head against for two days.
Here is sample code for setting up the problem:create table #blindman
(pkey smallint primary key,
fkey char(1),
updateddatetime)
insert into #blindman (pkey, fkey, updated)
select1, 'A', '1/1/2006'
UNION
select2, 'B', '1/1/2006'
UNION
select3, 'A', '1/2/2006'
UNION
select4, 'B', '1/2/2006'
UNION
select5, 'A', '1/4/2006'
UNION
select6, 'B', '1/2/2006'
UNION
select7, 'A', '1/3/2006'
UNION
select8, 'B', '1/3/2006'
UNION
select9, 'A', '1/5/2006'
UNION
select10, 'B', '1/5/2006'
drop table #blindman
Notice that for fkey 'B', there are two entries with '1/2/2006', and for fkey 'A' the updated values are not in synch with the order of the primary key.
The challenge: determine the next pkey for each pkey value, ordered by [updated], and using pkey as a tie-breaker when two records have the same [updated] value.
Here is the desired output for the sample data:pkey fkey updated nextpkey
------ ---- ---------- --------
1 A 2006-01-01 3
3 A 2006-01-02 7

Records 9 and 10 are missing because they have not succeeding records, though I'd be just has satisfied to include them with NULL as their nextpkey value.

Who's up for the challenge?
