an error, incorrect syntax, was generated when the following query was tried:
CREATE TABLE ASPNET2
(id smallint IDENTITY(1,1) PRIMARY KEY,
word nvarchar(50) NOT NULL,
definition nvarchar(MAX) NOT NULL)
I wanted to use nvarchar(MAX) because something I read suggested that I couldn't do editing with the controls if a variable was set to text.
Thanks.

Hello,
we have automated build on every night. In our solution is SSIS project, where each package is encrypted per password. We call build process per command line like this..
C:ProgrammeMicrosoft Visual Studio 8Common7IDEdevenv.exe (c:DevelopmentX3\X3.sln /build Release)' in 'c:DevelopmentProjectsDailyBuild
Through build process we get a error:
External Program Failed: C:ProgrammeMicrosoft Visual Studio 8Common7IDEdevenv.exe (return code was 1):
We think a reason is, that on build of SSIS project must be entered a password. You can wonder for what we need that SSIS packages are part of our build. We hope that on build process is also created Deployment Utility, if so set in dtproject.user. Is it so? Is there any way to create Deployment utility on automated build process? Can be a password provided pre command line?
with best regards

Hello to all,
I have now two tabels ( Ta and Tb). the tabel includes difference attributte. I want to build this two tables together.
I used this query:
select * from Ta where Ta.Id = @ID union all select * from Tb where Tb.IdOfa = @ID
but it doesn't work and the following error message comes
"All inquiries in an SQL application, which contain a union operator, must contain directly many expressions in their goal lists "
I am building my SELECT on the fly by use of IF statements something like:
SET @searchParam = @searchParam + ' AND tblXYZ.country = ' + @searchStringCountry
Then I am trying to use @searchParam as my WHERE clause:
WHERE@searchParam
How do I get the string out of @searchParam to use as my WHERE clause?
Thanks in advance!
I've got a table that stores individuals, and their organization all in one table, with basic information about each (contactId, name, primary address, phone, etc.). There is also, for each line, a true/false field 'PerOrg' that lets me know if it's a person (true), or an organization (false); and a 'OrgKeyCode' field that has the contactId for the person organization.
I'm looking to make an update query that will make the primary address for all individuals set to the primary address for their corresponding organization. Here's my queries to find the items:
This gets all of the organization, their contactId and their primary Address (as long as they have one).
SELECT ContactID, FullName, PrimaryAddressType
FROM tblContactInformation
WHERE PrimaryAddressType IS NOT NULL AND PerOrg = '0'
This gets a list of all of the individuals that have an organization assigned.
SELECT ContactID, FullName, OrgKeyContactID, PrimaryAddressType
FROM tblContactInformation
WHERE PerOrg = '1' AND OrgKeyContactID IS NOT NULL
Now I need to create an update query that sets the Primary Address for individuals to the primary address for their corresponding organization. Here's what I've got worked out so far: (just the basics).
UPDATE tblContactInformation
SET PrimaryAddressType =
WHERE PerOrg = '1'
At issue is, I'm not sure how to pull the primary address only from the organization into the SET line. Do I need to save my first query, then somehow call it in my update query, where the contactID = the OrgKeyCode? Or something like that?
I have a table which tracks changes by user, department and date. I want to construct a query which returns two numbers, the first is all the changes by department on a certain date. The second is all changes by user on the same date. I know that the queries seperately will look like,
SELECT COUNT(User) As NumberByUser
FROM Table
WHERE (Date = 'DateGoesHere') AND (User= 'UserGoesHere')
GROUP BY User
SELECT COUNT(Department) As NumberByDepartment
FROM Table
WHERE (Date = 'DateGoesHere') AND (Department = 'DepartmentGoesHere')
GROUP BY Department
But how do I go about linking the two in the same query? Any help would be appreciated, thanks!
Hello,I am using SQL 2005 and Cognos' Data Manager. It is an ETL tool fordata warehousing.I have a problem with time it takes to load new changes, and I amseeking advice on a better way to manage the data.I have a table that tracks student attendance and it contains about 13million records. On a daily basis, there are 5,000 - 20,000 inserts and10,000 - 50,000 updates.The daily data comes for two different text files from my operationsystem; current and historical (CLSFIL and CLSHIS).The data is loaded into a staging area from the operational system,where data cleansing and other fields are added to the table.The final step is delivering the table to my target database, which isused for reporting.Heres the situation: I find it takes 45 minutes to do a relationalupdate, where only the records that changed in the last day will beloaded. However, if I choose the native API load instead of aRelational Load, it can load all 13M records in 7 minutes. The table isheavly indexedAt some point, the API load will take more time than the relationalload, (the changes and new records will remain a constant, but the filewill continue to grow).I'm seeking another solution is more efficient. I'm considering twotables for history and current and creating a view for reporting via aunion.This a good idea? How can I make the view effeicent to use the whereclause? Looking to bounce around ideas.Other Ideas?Thanks in AdvanceRob(I maintain the key relationships in the tool, not the tables.

Hi there,
I am trying to build a proc that uses a loop to import data into several tables. The data is copied into the appropriate table according to the contents of the variable @PracticeCode. I am also trying to add a date value to each record as it is added to the table. I thought that the best way to do this would be t use the sp_executesql stored proc. but I am having difficulty getting it to work. Here's what I have done so far:
-- insert data into proper tables with extract date added
SET @SQLString ='INSERT INTO GMS_48hrAccess.dbo.tbl_Surgery'+@PracticeCode+' SELECT
SurgeryKey,'+
@extractDate+',
ClinicianCode,
StartTime,
SessionGroup,
[Description],
SurgeryName,
Deleted,
PremisesKey
FROM GMS_48hrAccess.dbo.tbl_SurgeryIn'
EXEC master..sp_executesql @SQLString
And here's the error message that I get:
Server: Msg 241, Level 16, State 1, Line 90
Syntax error converting datetime from character string.
I understand why I am getting this error I just can't seem to fix it. I've consulted BOl and have tried various Parameter combinations but to no avail.
Can anyone help?
Thanks
Hi GuysI don't want to keep asking for your help all the time on each individualquery, so could you please help me to break the myths on the following:1) I have 2 tables. Once is called ACCOUNTS and the other ACCOUNTBUDGET.ACCOUNTS includes all of the usual details for customers and suppliers, egthe account code (as ACCOUNTID), the account name (as NAME), etc.ACCOUNTBUDGET basically holds a transaction line for each month and it'scorresponding year to store the turnover for that month, eg one row containsACCOUNTID, PERIOD (ie the month), YEAR and TURNOVER.Now a lot of the SQL 6.5 tables that I deal with are in this vein and theusual query is that I want to list all of the ACCOUNTIDs and NAMEs thatexist in the ACCOUNTS table and then show for example what their TURNOVER isfor a applicable PERIOD and YEAR, which are all held in the ACCOUNTSBUDGETtable.Now if I do a quick query using MS Query all I get are rows that haverelated values in both the ACCOUNTS and ACCOUNTSBUDGET table when I havespecified say a certain PERIOD and YEAR.The main point of my current reporting problem is that I want to show allthe ACCOUNTIDs and NAMEs in ACCOUNTS that have zero TURNOVER for aparticular PERIOD and YEAR.I'm positive that I have to create a 2 step query/join, but I don't know howto do it. What is the method? People in this NG, can rattle one up inseconds, but I just don't see the logic. Can you help me with this queryand let me know how you manage to fathom it.2) Are there any good web sites that explain in kiddie form how to do thissort of thing?I really appreciate your help on this.RegardsLaphan

Hi Everyone,I'm drawing a blank here and I am hoping someone can point me in the right direction. I have a table with the following columns (some omitted)IDGUIDPageNameParentPageID I want to build a hierarchical navigation system (2-tier). The conceptual problem that I am running into was getting this information from the same table. Initially I was going to use a nested repeater but I am thinking a treeview would be better. Anyway, the problem is the query. How would I start with something like this? Let's use the following as an exampleRows(ID '1', GUID '888....', PageName 'Page A', ParentPageID '-1')(ID '2', GUID '111....', PageName 'Page B', ParentPageID '-1')(ID '3', GUID '222....', PageName 'Page C', ParentPageID '-1')(ID '4', GUID '375....', PageName 'Page 1', ParentPageID '1')(ID '5', GUID '562....', PageName 'Page 2', ParentPageID '1')(ID '6', GUID '874....', PageName 'Page 3', ParentPageID '2')
(ID '7', GUID '388....', PageName 'Page 4', ParentPageID '3') So, I want to be able to build a query so that I can do the followingPage A Page 1 Page 2Page B Page 3Page C Page 4 Any help would be greatly appreciated. Thanks!

str3 3
str4 4
OnEnd :
Name value
===============
str5 11
str6 12

Hi all,I'm a newbie to SQL and I need help with investigating what ways arepossible to build an interface of some sort that wraps around a SQLquery script.I have a simple SQL query which we normally run inside Query Analyzerto update certain fields in the SQL DB based on FQDN provide by theuser. The user normally opens up the query, edit the script to replaythe xxxxx in the line "set @FQDN="xxxxx" with the node name and thenfires it off.I would like to know what are the ways to wrap a simple user interfacearound it so the user does not have to open and edit the scriptdirectly. A simple GUI or Excel type form interface that has a freeform text field for input and then a button to run the script.Obviously, I would like to see the output in some sort of output paneas well.Is this something that can be done in Query Analyzer ?Thanks in advance,Michael.

Hi all,
I have access to a stored procedure that was written previously for a process that uses the output from the stored procedure to provide input to a BCP operation in a bat file that builds a flat text file for use in a different system.
To continue with the set up, here is the stored procedure in question:
CREATE PROCEDURE [dbo].[HE_GetStks] AS
select top 15
Rating,
rank,
coname,
PriceClose,
pricechg,
DailyVol,
symbol
from
(selectf.rating,
f.rank,
s.coname,
cast ( f.priceclose as decimal(10,2)) as PriceClose,
cast ( f.pricechg as decimal(10,2)) as pricechg,
f.DailyVol,
f.symbol
from dailydata f, snames s
where f.tendcash = 0
and f.status = 1
and f.typ = 1
and f.osid = s.osid) tt
order by rating desc, rank desc
GO
The code in the calling bat file is:
REM *************************
REM BCP .WRK FILE
REM *************************
bcp "exec dailydb.[dbo].[HE_GetStks]" queryout "d:TABLESINPUTHE_GetStks.WRK" -S(local) -c -U<uname> -P<upass>
This works just peachy in the process for which it was designed, but I need to use the same stored procedure to grab the same data in order to store it in a historical table in the database. I know I could duplicate the code in a separate stored procedure that does the inserting into my database table, but I would like to avoid that and use this stored procedure in case the select statement is changed at some point in the future.
Am I missing something obvious in how to utilize this stored procedure from inside an insert statement in order to use the data it outputs? I know I cannot use an EXECUTE HE_GetStks as a subquery in my insert statement, but that is, in essence, what I am trying to accomplish.
I just wanted to bounce the issue of y'all before I go to The Boss and ask him to change the procedure to SET the data into a database table directly (change the select in the proc to an INSERT to a local table) then have the external BAT file use a GET procedure that just does the select from the local table. This is the method most of our similar jobs use when faced with this type of "intercept" task.
Any thoughts?
When importing a Microsoft Access97 database table, I noticed it imported Text fields as datatype NVARCHAR instead of VARCHAR. Why is this, and will this cause me any problems in the future (i.e. related fields in other tables may be VARCHAR,etc)? If so, what can I do about it?

View 3 Replies View RelatedHey folks, the question is fairly simple, unfortunately the answer has proven rather elusive.
Is it possible to declare a variable which would then be used to identify either a column or table in an SQL statement?
Here's a basic idea of what I'd like to do:
DECLARE @myVar AS NVARCHAR(50)
SELECT *
FROM @myVar
or
DECLARE @myVar AS NVARCHAR(50)
SELECT @myVar
FROM MyTable
I'm probably looking for some sort of built in function that will accept an argument here... like COLUMN(@myVar) or something of the like. I just don't know where to look...
I had this question for quite a long time.
It seems the latter one don't take any extra storage space than the previous one.
As long as the real string length is less than 10.
Is that mean the latter one not cost anything?
I once heard the different is when they are in memory. But not sure of it.
Can anyone explain it and provide some official reference on it?
Thank.
