Hi,
I have a user-defined function which returns a table (call it '@a'),
and has another table defined as a variable (call it '@b'). When I try
to do the following query, I get "Must declare the variable '@b'" and
"Must declare the variable '@a'." How do I remedy this?
The query:
UPDATE @a
SET
stuff =
(SELECT otherStuff From @b
WHERE @b.someID = @a.someID)
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

Hi,
I am trying to build a website in C# for a university project, and am having trouble updating a table from the code (at which I'm not too hot on writing). I can manage to get the SQL syntax to work in SQL Server 2005, but when I transfer it to the Visual Web Developer page it doesn't update. Would anyone be able to kindly point out where I am going wrong? My code (apologies for the amount) is;protected void CalculateEmissionsAndTotal()
{
//Create the ConnectionSqlConnection sqlConn =
new SqlConnection("server=Acer-Laptop\SQLEXPRESS; database=NeuCar; Trusted_Connection=true");
//Open the connection
sqlConn.Open();
//Create the Command, passing in the SQL statement and the ConnectionString queryString = "DECLARE @Today DATETIME SELECT @Today = Current_Timestamp Declare @TotalCharge int DECLARE @EmissionsUrban int DECLARE @EmissionsCountry int SELECT @TotalCharge = ((MemberPayment.MileageUrban * Vehicle.EmissionsPerGramUrban) * 0.05) + ((MemberPayment.MileageCountry * Vehicle.EmissionsPerGramUrban) * 0.05) FROM [NeuCar].[dbo].[MemberPayment] JOIN [NeuCar].[dbo].[Vehicle] ON MemberPayment.Registration = Vehicle.Registration JOIN [NeuCar].[dbo].[Member] ON Vehicle.UserName = Member.UserName WHERE (Member.UserName = @myUserName) AND (MemberPayment.PaymentDate >= DATEADD(dd,-(DAY(DATEADD(mm,-1,@Today))-1),DATEADD(mm,0,@Today))) SELECT @EmissionsUrban = ((MemberPayment.MileageUrban * Vehicle.EmissionsPerGramUrban) * 0.05) FROM [NeuCar].[dbo].[MemberPayment] JOIN [NeuCar].[dbo].[Vehicle] ON MemberPayment.Registration = Vehicle.Registration JOIN [NeuCar].[dbo].[Member] ON Vehicle.UserName = Member.UserName WHERE (Member.UserName = @myUserName) AND (MemberPayment.PaymentDate >= DATEADD(dd,-(DAY(DATEADD(mm,-1,@Today))-1),DATEADD(mm,0,@Today))) SELECT @EmissionsCountry = ((MemberPayment.MileageCountry * Vehicle.EmissionsPerGramCountry) * 0.05) FROM [NeuCar].[dbo].[MemberPayment] JOIN [NeuCar].[dbo].[Vehicle] ON MemberPayment.Registration = Vehicle.Registration JOIN [NeuCar].[dbo].[Member] ON Vehicle.UserName = Member.UserName WHERE (Member.UserName = @myUserName) AND (MemberPayment.PaymentDate >= DATEADD(dd,-(DAY(DATEADD(mm,-1,@Today))-1),DATEADD(mm,0,@Today))) UPDATE MemberPayment SET TotalCharge = @TotalCharge, EmissionsUrban = @EmissionsUrban, EmissionsCountry = @EmissionsCountry WHERE (Registration = @myRegistration); ";

I have been looking at the project Real reference implementation for doing auditing of data uploads. The tables and store procedures are in place using identical field and variable names. However, when running the package it does not update the relevant log entry with the end time and status.
I have performed the process manually running the stored procedures, providing the values directly and everything works fine.
I can only assume that the LogID variable is not being updated during the run and therefore the onEnd procedure cannot update the relevant log entry.
One side effect is that it does update the record when it€™s the first record entered into the table but not on any other inserts. Clearing the table each time is not an option.
This has become rather frustrating and would appreciate any assistance.
Thanks.
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();
}
I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?
How do I use table names stored in variables in stored procedures?
Code Snippetif (select count(*) from @tablename) = 0 or (select count(*) from @tablename) = 1000000
I receive the error 'must declare table variable '@tablename''
I've looked into table variables and they are not what I would require to accomplish what is needed.
After browsing through the forums I believe I need to use dynamic sql particuarly involving sp_executesql. However, I am pretty new at sql and do not really understand how to use this and receive an output parameter from it(msdn kind of confuses me too). I am tryin got receive an integer count of the records from a certain table which can change to anything depending on what the user requires.
Code Snippet
if exists(Select * from sysobjects where name = @temptablename)
drop table @temptablename
It does not like the 'drop table @temptablename' part here. This probably wouldn't be an issue if I could get temporary tables to work, however when I use temporary tables i get invalid object '#temptable'.
Heres what the stored procedure does.
I duplicate a table that is going to be modified by using 'select into temptable'
I add the records required using 'Insert into temptable(Columns) Select(Columns)f rom TableA'
then I truncate the original table that is being modified and insert the temporary table into the original.
Heres the actual SQL query that produces the temporary table error.
Code Snippet
Select * into #temptableabcd from TableA
Insert into #temptableabcd(ColumnA, ColumnB,Field_01, Field_02)
SELECT ColumnA, ColumnB, Sum(ABC_01) as 'Field_01', Sum(ABC_02) as 'Field_02',
FROM TableB
where ColumnB = 003860
Group By ColumnA, ColumnB
TRUNCATE TABLE TableA
Insert into TableA(ColumnA, ColumnB,Field_01, Field_02)
Select ColumnA, ColumnB, Sum(Field_01) as 'Field_01', Sum('Field_02) as 'Field_02',
From #temptableabcd
Group by ColumnA, ColumnB
The above coding produces
Msg 208, Level 16, State 0, Line 1
Invalid object name '#temptableabcd'.
Why does this seem to work when I use an actual table? With an actual table the SQL runs smoothly, however that creates the table names as a variable problem from above. Is there certain limitation with temporary tables in stored procedures? How would I get the temporary table to work in this case if possible?
Thanks for the help.
I am trying to update one table when records are inserted in another table.
I have added the following trigger to the table “ProdTr” and every time a record is added I want to update the field “Qty3” in the table “ActInf” with a value from the inserted record.

Hello friends,
I am new to the SQL Server 2005 development.
From last 1 week or so, i have been facing very strange problem with my sql server 2005s database
which is configured and set on the hosting web server. Right now for managing my sql server 2005 database,
i am using an web based Control Panel developed by my hosting company.
Problem i am facing is that, whenever i try to modify (i.e. add new columns) tables in the database,
it gives me error saying that,
"There is already an object named 'PK_xxx_Temp' in the database. Could not create constraint. See previous errors.
Source: .Net SqlClient Data Provider".
where xxx is the table name.
I have done quite a bit research on the problem and have also searched on the net for solution but still
the problem persist.
Thanks in advance. Any help will be appreciated.

hi all!
I am using table variables instead of creating a temp table because it seems to be faster
But now I need qualify the table variable so I can join it with another table having a field with same name of a field from the table variable. U know if I can do that?
ex: with temp table
create table #tmp.... (F1...)
#tmp.f1
with table variable
declare @temp table(...
@table.f1 - can´t do it
the first question is if I can join the table variable with another table and how to do that qualifying the variable table, that is, putting the name of the var temp with the field, because the other table has a field with same name
thank to all and happiness for all 2004
Hello, all. I'm attempting to insert data into a table variable using dynamic SQL created at runtime.
However, with a Table variable, SQL server will not allow the EXEC method to be used in an INSERT statement.
How do I go about this?
I am trying to add a variable to a temporary table name. Throughout a stored procedure, I do a lot with this table. I delete, insert, update, and query this table. Is there a way to do the following without having to set the entire 'select * from ...' line as a variable? Below is what I am trying to accomplish. It all works until the select * line. Is there a way to accomplish what I am trying to do below?
Declare @table varchar(255),
@PassedID integer
set @passedID=5
set @table="test"+CONVERT(varchar(20), @passedID)
select * from @table
Thanks,
Jon
I have a cursor which populates a variable with the name of each user table within my DB.
I'm trying to copy the tables one at a time by using a command like this:
SELECT * INTO @NewTable FROM @OrigTable
Query analyzer tells me that there's incorrect syntax near the keyword 'INTO'.
This seems fair enough to me as I assume it's trying to put the data into the variable rather than the table name which is held within the variable. Does any know how I can get around this?
Are there any alternative ways of copying the table structure (preferable without the data)?
BTW both variables are of type char(100)
I have a table that has two columns POLICY_NUMBER and POLICY_TYPE
POLICY_NUMBER POLICY-TYPE
123 1
123 1
123 1
567 2
567 2
789 1
789 1
345 1
345 1
345 1

policy_type_count policy_type
3 1
