OpenQuery Syntax Using Variables

May 23, 2007

I have an openquery statement with a parameter embeded as a variable:



declare @product varchar(3)

set @product= 'ABC'

select * from openquery(SomeServer,'

SELECT Description, Size

FROM Products

WHERE

Group = ''XY'' AND

Code = ''' + @product + '''')



When I run it I get the following message:



Msg 102, Level 15, State 1, Line 8

Incorrect syntax near '+'.



When I hard code the "Code" value, like so:



Code = ''ABC''')



...it works fine.



I am at a loss and would appreciate any help on this.



Thanks in advance

Syntax For Updating Table Variables

Jul 23, 2005

What would be the correct syntax, if any, that allows updating a tablevariable in a statement that uses the same table variable in a correlatedsubquery? Here's an example:DECLARE @t table (N1 int NOT NULL, N2 int NOT NULL)UPDATE @t SETN1 = (SELECT COUNT(1)FROM @t AS tWHERE t.N2 < @t.N2)This doesn't compile, complaining about "variable @t" in the WHERE clause.I'm not so interested in a way to rewrite this particular statement to makeit work, but rather in a general way to refer to table variables in thecontexts where correlation names cannot be used.Thank you.--remove a 9 to reply by email

Correct Syntax Using Variables Inside SQL Queries (SqlCommand)

Mar 30, 2008

I have a test page where I'm using SqlConnection and SqlCommand to update a simple database table (decrease a number).
I'm trying to figure out how to make a number in the database table to decrease by 1 each time a button is being pressed. I know how to update the number by whatever I want to, but I have no idea what the correct syntax is for putting variables inside the query etc. Like "count -1" for instance.
The database table is called "friday" and the one and only column is called "Tickets".
Here's the code behind the button:protected void Button1_Click(object sender, EventArgs e)
{SqlConnection conn;
conn = new SqlConnection("Data Source=***;Initial Catalog=***;Persist Security Info=True;User ID=***;Password=***");
conn.Open();int count = -1;
 SqlCommand cmd = new SqlCommand("select Tickets from friday", conn);
count = (int)cmd.ExecuteScalar();if (count > 0)
{
 string updateString = @"
update friday
set Tickets = 500" ;   <------ Here I want to set Tickets like "current count -1"SqlCommand cmd2 = new SqlCommand(updateString);
cmd2.Connection = conn;
cmd2.ExecuteNonQuery();
}
else
{
}
conn.Close();
}

Execute DTS 2000 Package Task Editor (Inner Variables Vs Outer Variables)

Sep 4, 2006

Hi,

I am not comfortable with DTS 2000 but I need to execute a encapsulated DTS 2000 package from a SSIS package. The real problem is when I need to pass SSIS variables to DTS 2000 package. The DTS 2000 package have 3 global variables that I can identify on " Execute DTS 2000 Package Task Editor - Inner Variables ". I believe the SSIS variables must be mapped on " Execute DTS 2000 Package Task Editor - OuterVariables ". How can I associate the SSIS variables(OuterVariables ) to "Inner Variables"? How can I do it? Much Thanks.

How To Design A Package With Variables So That I Can Run It By Dos Command Assigning Values To Variables?

Jan 24, 2006

Hi,

I would like to design a SSIS package, which have couple of variables. It loads a xls file specified in a variable [varExcelFileFullPath] .

I will run it by commands: exec xp_cmdshell 'dtexec /SQL ....' (pls see an example below).

It seems it does not get the values passed in for those variables. I deployed the package to a sql server.

are there any grammar errors here? I copied it from dtexecui. It worked inside Dtexecui not in dos command.

exec xp_cmdshell 'dtexec /SQL "LoadExcelDB" /SERVER test /USER *** /PASSWORD ****

/MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EW

/LOGGER "{6AA833A1-E4B2-4431-831B-DE695049DC61}";"Test.SuperBowl"

/Set Package.Variables[User::varExcelFileName].Properties[Value];"TestAdHocLayer"

/Set Package.Variables[User::varExcelWorkbookName].Value;"Sheet1$"

/Set Package.Variables[User::varExcelFileFullPath].Value;"D: estshareTestAdHocLayer.xls"

/Set Package.Variables[User::varDestinationTableName].Value;"FeaturesTmp"

/Set Package.Variables[User::varPreSQLAction].Value;"delete from FeaturesTmp"

'

Incorrect Syntax Near The Keyword CONVERT When The Syntax Is Correct - Why?

May 20, 2008

Why does the following call to a stored procedure get me this error:


Msg 156, Level 15, State 1, Line 1

Incorrect syntax near the keyword 'CONVERT'.




Code Snippet

EXECUTE OpenInvoiceItemSP_RAM CONVERT(DATETIME,'01-01-2008'), CONVERT(DATETIME,'04/30/2008') , 1,'81350'




The stored procedure accepts two datetime parameters, followed by an INT and a varchar(10) in that order.

I can't find anything wrong in the syntax for CONVERT or any nearby items.


Help me please. Thank you.

Which Is Faster? Conditional Within JOIN Syntax Or WHERE Syntax?

Mar 31, 2008

Forgive the noob question, but i'm still learning SQL everyday and was wondering which of the following is faster? I'm just gonna post parts of the SELECT statement that i've made changes to:

INNER JOIN Facilities f ON e.Facility = f.FacilityID AND f.Name = @FacilityName

OR

WHERE f.Name = @FacilityName


My question is whether or not the query runs faster if i put the condition within the JOIN line as opposed to putting in the WHERE line? Both ways seems to return the same results but the time difference between methods is staggering? Putting the condition within the JOIN line makes the query run about 3 times faster?

Again, forgive my lack of understanding, but could someone agree or disagree and give me the cliff-notes version of why or why not?

Thanks!

Converting Rrom Access Syntax To Sql Syntax

Sep 23, 2007


Ok I am tying to convert access syntax to Sql syntax to put it in a stored procedure or view..
Here is the part that I need to convert:

SELECT [2007_hours].proj_name, [2007_hours].task_name, [2007_hours].Employee,
IIf(Mid([task_name],1,3)='PTO','PTO_Holiday',
IIf(Mid([task_name],1,7)='Holiday','PTO_Holiday',
IIf(Mid([proj_name],1,9) In ('9900-2831','9900-2788'),'II Internal',
IIf(Mid([proj_name],1,9)='9900-2787','Sales',
IIf(Mid([proj_name],1,9)='9910-2799','Sales',
IIf(Mid([proj_name],1,9)='9920-2791','Sales',

)
)
)
)
) AS timeType, Sum([2007_hours].Hours) AS SumOfHours
from................

how can you convert it to sql syntax

I need to have a nested If statment which I can't do in sql (in sql I have to have select and from Together for example ( I can't do this in sql):
select ID, FName, LName
if(SUBSTRING(FirstName, 1, 4)= 'Mike')
Begin
Replace(FirstNam,'Mike','MikeTest')
if(SUBSTRING(LastName, 1, 4)= 'Kong')
Begin
Replace(LastNam,'Kong,'KongTest')
if(SUBSTRING(Address, 1, 4)= '1245')
Begin
.........
End
End

end




Case Statement might be the solution but i could not do it.






Your input will be appreciated

Thank you

Using Functions In Openquery

Jul 20, 2001

I'm trying to use the date() function in an openquery statement in query analyzer and I keep getting an illegal symbol ")" error. The statement is :

select *
from openquery([Big Blue], 'select cde_date, cde_item from acch1 where cde_date < date()')

The objective is to find records where cde_date is prior to today. The syntax works fine if I execute it on the mainframe in QMF and the ODBC connection works fine if I hard code the value. What I need is the ability to use the function so I can run the query on subsequent days without having to edit it.

Any suggestions??

OpenQuery Using A Variable

Jan 29, 2004

Hi,

Here's what I did:

1) I declared a new VARCHAR(2000) variable called CQUERY like this:
DECLARE @CQUERY VARCHAR(2000)
2) I put a string query in the variable:
SET @CQUERY = 'SELECT ...'

Now, when I try to execute the OpenQuery method using that variable, it fails.

Here's the call:
SELECT * FROM OPENQUERY(OracleSource, @CQUERY)

I get the following error:
Server: Msg 170, Level 15, State 1, Line 13
Line 13: Incorrect syntax near '@CQUERY'.

Don't tell me I can't use a variable instead of a static query? What am I doing wrong?

Thanks,

OPENQUERY &&amp; Permissions

Oct 23, 2007

I have a dataming stored procedure. it works fine on it own, thanks to help from this forum. However, when i try to run aggregate funtions on the table it returns using sql server I get:

"The OLE DB provider "MSOLAP" for linked server "DM" indicates that either the object has no columns or the current user does not have permissions on that object."

This works:

CALL Assemby.Namespace.MyFunction('[model]', 'db','table',0)

And this works:

SELECT SUM([prediction]) as value, count([prediction]) as count FROM OPENQUERY(DM,'
--DMX query that sproc produces and executes
')

but this:
SELECT SUM([prediction]) as value, count([prediction]) as count FROM OPENQUERY(DM,'
CALL Assemby.Namespace.MyFunction(''[model]'', ''db'',''table'',0)
')

gives this:

The OLE DB provider "MSOLAP" for linked server "DM" indicates that either the object has no columns or the current user does not have permissions on that object.

Could anyone point me in the right direction?

Problem With OPENQUERY

Issues With OpenQuery

May 19, 2008

We are running the following query against a MYSQL database that runs a third party software.


SELECT Email, CONVERT(INT, count) AS clicks, date AS Last_Clicked_Date
FROM OPENQUERY(MYSQL, 'SELECT Email, SUM(count) count, MAX(date) date FROM tracking WHERE action="click" GROUP BY Email')

We are upgrading that software to the latest version. This requires a migration from MYSQL to PostGres.
There are some schema changes involved

Current MYSQL field name New PostGres field name
email email_address
date tracking_date
action action_name

I've modified the query to use the new fields

SELECT Email_address, CONVERT(INT, count) AS clicks, date AS Last_Clicked_Date
FROM OPENQUERY(MYSQL, 'SELECT Email_address, SUM(count) count, MAX(tracking_date) date FROM tracking WHERE action_name="click" GROUP BY Email_address')

and I get the following error message -

Msg 7399, Level 16, State 1, Line 1

The OLE DB provider "MSDASQL" for linked server "test" reported an error. The provider reported an unexpected catastrophic failure.

Msg 7350, Level 16, State 2, Line 1

Cannot get the column information from OLE DB provider "MSDASQL" for linked server "test".



When I run this query it works -

select email_address, tracking_date

from openquery(test, 'select * from tracking')


What am I doing wrong?
