Query Question - Check Before Insert
Dec 1, 2003
I have a table, emailaddresses with an emailaddress field.
before i do an insert from a stored proc, i want to check if the emailaddress is already in the database.
pseudo-code:
if emailaddresssparameter is IN emailaddress then
do not insert
else
insert into table
end
i've got the insert statement and the stored proc, but how do i write the check to see if it's already there? I mean i could do a select * from emailaddress wehre emailaddress=emailaddressparam
but how to i test it? if the count=1 then skip?
here's my proc now:
ALTER PROCEDURE dbo.AddOneEmailAddress
(
@emailAddress varchar(255),
@emailID int=0 OUTPUT
)
AS
/* SET NOCOUNT ON */
insert into EmailAddresses
(email_address)
values
(@emailAddress)
set @emailID=@@identity
RETURN @@identity

I have a pretty standard form that inserts users name, office, and team. It generates a random 10 digit ID for them. How would i got about checking the table to make sure that ID doesn't exist?
Here's my insert code.
string strConnection = ConfigurationManager.ConnectionStrings["TimeAccountingConnectionString"].ConnectionString; SqlConnection myConnection = new SqlConnection(strConnection);
string usercode = GenPassWithCap(9);
String insertCmd = "INSERT into users (ID, firstname, lastname, office, team) values (@id, @firstname, @lastname, @office, @team)"; SqlCommand myCommand = new SqlCommand(insertCmd, myConnection);
myCommand.Parameters.Add(new SqlParameter("@id", SqlDbType.VarChar, 10)); myCommand.Parameters["@id"].Value = usercode;
myCommand.Parameters.Add(new SqlParameter("@firstname", SqlDbType.VarChar, 50)); myCommand.Parameters["@firstname"].Value = txtFirstName.Text;
myCommand.Parameters.Add(new SqlParameter("@lastname", SqlDbType.VarChar, 50)); myCommand.Parameters["@lastname"].Value = txtLastName.Text;
myCommand.Parameters.Add(new SqlParameter("@office", SqlDbType.VarChar, 75)); myCommand.Parameters["@office"].Value = dwnOffice.SelectedValue;
myCommand.Parameters.Add(new SqlParameter("@team", SqlDbType.VarChar, 20)); myCommand.Parameters["@team"].Value = dwnTeam.SelectedValue;
myCommand.Connection.Open();
myCommand.ExecuteNonQuery();
Do I run a completey different select command before hand and try to match that field?

I have 3 tables - Data, Facility and FacilityKey
The FacilityKey table will hold the Data ID and Facility ID based on a series of check boxes on a form.
My question is what is the best way to do the insert into the FacilityKey table from the form? If 5 facilities are checked I don't want to do 5 separate calls to the database for inserts, but I'm a bit confused on what the best method would be.
Thank you!

I need help thinking about this problem :-)
I have an SSIS pkg that automatically downloads financial extracts from an ftp site. Once the files are downloaded, I load the extract to a table. The table is first deleted before the insert, so that each time the table has "fresh" data (whatever was in the extract for that day).
Once the extract data is in the table, I load the data into yet another table that combines data from many tables. Simple enough.
Problem is, sometimes when I download the extract, it hasn't been updated yet, so I'm downloading an OLD extract. This old data then gets loaded into the first table. That's ok, because it doesn't really hurt anything. I can always delete the table and reload it if necessary.
The problem occurs when the old data goes from this table into the OTHER table. We don't want old data in this other table!
I need a way to check that I'm not loading the same data 2 days in a row into the OTHER table.
I realize that I might be able to solve this problem without using SSIS, but the solutions I've come up with so far aren't 100% satisfactory. I can use a query to check dates and that sort of thing, but it isn't foolproof, and would create problems if I need to manually force the process though, that is, if I need to override the date logic.
Anyways, I'm wondering if there's an SSIS approach to this problem... I can't rely on timestamps on the data files either. They're not accurate.
This is has been very perplexing to me.
Thanks

Can you tell me if this is possible? (and how to do it!!)
The application is VS2005, with sql database.
I want to check if a specific column exists in a specific table in the database and if not then add it, all via my application.
I'm happy knowing how to connect to the database & pass sql commands (as I'm doing that anyway to set off backups), but not the actual queries I'd need.

I have two tables from two different Databases
DB1.dbo.Table1 and DB2.dbo.Table2
eX:
Table 1
KEY LName FName Updated
1 GYM ABC Y
1 TIM ABC N
1 PIN ABC N
2 QWE SAD Y
......
....
Table 2
KEY LName FName Updated
1 JIM ABC Y
2 QWE SAM Y
....
....
1) Table 1 and Table 2 are of same structure.
2) In table2, as in above example, few changes have beeen done for KEY1 AND Update =Y, Similarly KEY= 2 AND UPDATED=Y, like for KEY= 1 LName was changed to JIM instead of GYM and for KEY= 2 FName has been changed to SAM instead of SAD.
3) Now I want to do this in SSIS where
a) Its going to process rows of Table2 and check in table1 according to KEY and UPDATE=Y and update the Table1 with Updated = N and Insert that particulra process row of Table2 into Table1
and hence Resultant of Table1 must be like this
Table 1
KEY LName FName Updated
1 GYM ABC N
1 TIM ABC N
1 PIN ABC N
1 JIM ABC Y
2 QWE SAD N
2 QWE SAM Y
......
....
Can somebody help me how to do this in SSIS. Thnaks a lot in advance

Hi,
How would I check if an insert via stored proc succeeded? Here's the proc I'm using:set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:<Author,,Name>
-- Create date: <Create Date,,>
-- Description:<Description,,>
-- =============================================
ALTER PROCEDURE [dbo].[showtube_addNewSUser]
-- Add the parameters for the stored procedure here
@UserId uniqueidentifier,
@FirstName nvarchar(32),
@LastName nvarchar(32),
@DescShort nvarchar(256),
@DescLong ntext,
@ClanID uniqueidentifier
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
Insert into dbo.Users (UserId, FirstName, LastName, DescShort, DescLong, ClanID)
values (@UserId, @FirstName, @LastName, @DescShort, @DescLong, @ClanID);
END
I tried adding a Return @@RowCount before the END statement, but it always seems to return -1. Could someone tell me what I'm doing wrong? Thanks.

I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:
---------------------------------
CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client]
FOR INSERT, UPDATE
AS
declare @currency as char(50)
declare @country as char(50)
declare cur cursor for SELECT currency, country
FROMinserted
OPEN cur
fetch cur into @currency, @country
WHILE @@FETCH_STATUS = 0
BEGIN
if not exists(select * from listinfoid where listname = 'currency' and listid = @currency)
begin
set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency')
CLOSE cur
DEALLOCATE cur
RAISERROR (@currency,16,-1) with log
return
end
if not exists(select * from listinfoid where listname = 'country' and listid = @country)
begin
set @country = (cast(@country as varchar (3)) + ' is not a valid contry')
CLOSE cur
DEALLOCATE cur
RAISERROR (@country,16,-1) with log
return
end
else
fetch cur into @currency, @country
END
CLOSE cur
DEALLOCATE cur
update Client set currency = UPPER(currency), country = UPPER(country)
---------------------------------
I use a cursor to handle multiple rows in an update query.
(SQL2000-server)
Is there an easier och better way to do this?
I´m a bit unsure of this code.
Thanx!

Is there a global variable or something of the sort that would tell me how long it took to execute a query??
I need to monitor my DB response times and we have a query that runs in under 2 seconds. So we want to run this query every couple of minutes and if it takes more than 12 sec to run, we want to send an email to our DB staff...
I know that I could take a time stamp before and after then subtract but I wanted to know if there was an easier way to do it..
Thanks.

i have a table which is having size and pieces information and say it is having following 4 records.
Size, pieces, sizeID, sizecombID (SizeCombination Id)
S, 1, 1, 1
M, 3, 2, 1
L, 3, 3, 1
XL, 1, 4, 1
Now suppose user enters all these 4 records which i will pass as xml string to my stored procedure.
Is there any way to check existense of all these 4 records in this table from the xml data which i pass by using one SQL statement ? Or what is the right way of checking it, Is it through using cursor ??
Finally after checking it should retrun SizeCombID for a existing record, and if record is not existent then it should add these 4 records in table and return the new SizeCombID.
Can somebody pls help on this..

Hello,
I have a dynamic query in the stored procedure, and the code looks something like this:
SET @section_test = 'SELECT sectioncode FROM ' + @tablename + ' WHERE sectioncode = "' + @condition + '"'
EXEC (@section_test)
What I need to do is try to check if the query returns any values using EXISTS (possibly), but at the same time I don't want to return the results of that dynamic query's select statement in my stored procedure. Is it possible?
Thanks.

we tried out the following code in query analyser -
create procedure TrialProc
as
select * from sakjdhf
when we executed this piece of TSQL in query analyser, we expected it to give an error or warning that no object by the name of sakjdhf exists ( as actually there is no such table or view in the database ). however to our surprise we got "command completed successfully " !!
does this mean the SQL server does not check for necessary objects when creating a stored procedure ? or is there some setting that we missed out whihch is causing SQL server to overlook the error in the code ?

i'm pretty familiar w/ mysql, but relatively new to ms sql. Since i can do a lot more w/ ms sql, I have been trying to do all tasks in sql queries or scripts, but i'm stumped on this one. I have a table that links two things together. t1 has rows id1 and id2. When a row has these two id's, there is a "link" between them. I'm trying to make a command or script that will see if there is only 2 links for any given id.
for example, it would loop through each row, and run this command:
SELECT COUNT(*) AS Expr1
FROM links
WHERE (Id1 = this_rows_id1) OR (Id2 = this_rows_id1)
and again w/ id2
and then i would be interested in any row that only had a count of 2. is this possible?

Hi,
I have come across this problem with SQL server both on 2000 and 2005. I am stating an example here.
I have two partitioned tables and a view on top of both tables as below:
create table [dbo].[Table_1]
(
[TableID] INTEGER PRIMARY KEY NONCLUSTERED
CHECK NOT FOR REPLICATION ([TableID] BETWEEN 1 AND 999),
[AnyOtherColumn] int NOT NULL ,
) ON [Primary]
GO
create table [dbo].[Table_2]
(
[TableID] INTEGER PRIMARY KEY NONCLUSTERED
CHECK NOT FOR REPLICATION ([TableID] BETWEEN 1000 AND 1999),
[AnyOtherColumn] int NOT NULL ,
) ON [Primary]
GO
create view TableView
as
select * from Table_1
union all
select * from Table_2
GO
Note the NOT FOR REPLICATION clause on the check constraint on the TableID column.
I then ran the query execution plan for the following query on both SQL server 2000 and 2005.
select * from TableView where TableID = 10
On both the versions the execution plan shows and Index seek on both the tables in the view. This means that my partitioning is not working. If I remove the primary key constraint from the TableID column, the same query on the view shows a table scan on all the underlying tables. This is even worse.
Next, create the same tables and views again, now without the NOT FOR REPLICATION clause on the check constraint as show below:
create table [dbo].[Table_1]
(
[TableID] INTEGER PRIMARY KEY NONCLUSTERED
CHECK ([TableID] BETWEEN 1 AND 999),
[AnyOtherColumn] int NOT NULL ,
) ON [Primary]
GO
create table [dbo].[Table_2]
(
[TableID] INTEGER PRIMARY KEY NONCLUSTERED
CHECK ([TableID] BETWEEN 1000 AND 1999),
[AnyOtherColumn] int NOT NULL ,
) ON [Primary]
GO
create view TableView
as
select * from Table_1
union all
select * from Table_2
GO
Now run the query execution plan for the same query again.
select * from TableView where TableID = 10
This time you would see that it does an index scan only on the first parititon table. This time it proves that the partitioning works.
I would like to know why does the NOT FOR REPLICATION clause in the check constraint make such a huge difference?
Is it a bug in SQL server?
Or am I missing any thing?
Any help appreciated.
Thanks

I am using the following approach to enable dynamic date calculations: [URL] ...
However, some measures I work with are percentages (not numeric values) and demand a different formula.
See example snippet bellow (first IIF statement)
/*Calendar*/
[Date Calculation].[Calculation].[Calendar Actual versus PY WK %] =
IIF
(
[measures].Name = "HSP2 %", -- < ThIs is where I am trying to check if the measure is a percetgae type
0, -- < When this is the case then do something different

Hi All,
Is it possible to check the local system date format and then change the format to another format using SQL command in VB.
Eg.
-check current system format dd/MM/yyyy
-change current system format to MM/dd/yyyy format
Thanks
Jam.
