OUTPUT clause with INSERT - sql-server

I have a vacation request program that will ultimately save the vacation request data to the DB and then send an email to the users supervisor.
I use the following query to INSERT a row into the DB.
String strSQLNew = "INSERT INTO tblWP_TS_VacRequest (VacReqID, ReqStatus, ApproveDate, SubmitDate, CreateDate, VacNotes, HRVacNotes)
OUTPUT Inserted.VacReqID
VALUES(NEWID(), '" + sReqStatus + "', NULL, GETDATE(), GETDATE(), '" + sVacNotes + "', '" + sHRVacNotes + "'); ";
sVacReqID = Cm.ex(Cm.pld, strSQLNew, "5000", null, null, null, null, null, null, null, true);
Cm.ex is a routine we use thoughout our code to access the DB.
I use OUTPUT Inserted.VacReqID because I need the newly created VacReqID for the next step in my program. As soon as the data is inserted, I want to display the data to the user. I use a SELECT statement WHERE VacReqID = this new ID. In the table I have a column called VacReqNum. This is a sequential number that is displayed to the user for reference. This column has the following properties: IsIdentity, Identity Increment = 1, Identity Seed = 1.
Most times everything works fine. The problem comes in on the rare occasion when two people, User A and User B, happen to use the program at the same time and hit SUBMIT at the same time.
User A will receive an email with her name and correct VacReqNum but with User B's requested days off.
User B will receive an email with all correct data.
When I look at tblWP_TS_VacRequest I see the inserted row for User B but nothing for User A. I am not understanding how this happens. I know that User A's data is inserted because of the VacReqNum that is on the email. To confirm this User B's VacReqNum is 1 more than User A. This is the first time that I have used OUTPUT and a column that is automatically incremented at one time. Is there something wrong with my INSERT/OUTPUT query?
I don't access the DB when I create the email. After the data is inserted I get the data and put in an array using the VacReqID. I use the array to populate the body of the email. This is the query I use to get the data to fill the array.
SELECT VacReqNum, CONVERT(nvarchar(10), ReqDay, 101) AS ReqDate, CAST(ReqHours AS decimal(4,1)) AS ReqHours, VacReqDay.VacReqID, VacReqDayID
FROM tblWP_TS_VacRequestDay VacReqDay
JOIN tblWP_TS_VacRequest VacReq ON VacReq.VacReqID = VacReqDay.VacReqID
WHERE VacReqDay.VacReqID = sVacReqID
ORDER BY CONVERT(nvarchar(10), ReqDay, 101)

How to insert username in VS2008(report edition)

I'm creating a new report (*.rdl), and there I want to add username who runs the script (insert).
I've tried on VS2008 through "built-in-fields" function which is "User ID", but it didn't work:
CREATE TABLE #Some_Table
(
Plan_date date null,
Plan_customer int null,
creator_id nvarchar(55) null
)
INSERT INTO Some_Table
(
[Plan_date] ,
[Plan_customer],
[creator_id]
)
SELECT
#p_plan_monthly,
#p_plan_clients,
#creator_id ="user id" --from built-in-fields
Expected result is: Column creator_id is filling with value of username from active directory who made insert through my report.
To reiterate my comment, as it's is incredibly important:
"You need to use a different account to access your data #whitefang. The sa account should never be used for something as mundane as a report. In truth it should never be used unless you really need sysadmin privileges, or you're doing something like recovering the server. You should have a service account that can do the respective tasks it needs to. If you can suffer injection through those reports, you're service is like an open book to whomever has access."
Now, onto your problem. I would add a further internal parameter on your report. Change the value of the parameter to have the default value of =User!UserID; this will be the ID of the user running the report (perhaps something like StackOverflow\Larnu).
Then map that report parameter to your dataset parameter #creator_id and change your INSERT statement to:
INSERT INTO Some_Table ([Plan_date],
[Plan_customer],
[creator_id])
VALUES (#p_plan_monthly, #p_plan_clients, #creator_id);
Q: "and there I want to add username who runs the script (insert)"
You can use these functions.
-- database user name
SELECT USER_NAME()
-- login identification name
SELECT SUSER_NAME()

How to update the SQL Server table based on different column value

I would like to update table called people from:
to
Could you please help?
You need to parse out the beginning of the email address to add it to the domain name. Do that by finding the CHARINDEX of the # symbol, then subtracting one. Use that value as the length parameter in a LEFT function call.
Once you have the name from the email address, CONCATenate it to the static value of your domainname\.
I included a WHERE clause that you may want to use if you have a large number of rows where the Username is already correct and you don't want to waste a bunch of writes replacing a string with a duplicate of that same string. You could leave the WHERE off if you prefer.
UPDATE People
SET Username = CONCAT('domainname\',LEFT([E-mailAddress],CHARINDEX('#',[E-mailAddress])-1))
WHERE
Username <> CONCAT('domainname\',LEFT([E-mailAddress],CHARINDEX('#',[E-mailAddress])-1));
If you are working on earlier versions (cause CONCAT() is for 2012+ versions) and also if you have NULLs in the UserName column, you can do like
CREATE TABLE T(
[E-MailAddress] VARCHAR(50),
UserName VARCHAR(45)
);
INSERT INTO T VALUES
('abc#domainname.com', 'abc'),
('zxc#fhlbdm.com', NULL),
('MNO#domainname.com', 'MNO'),
('pqr#domainname.com', 'pq'),
('tyu#domainname.com', 'domainname\tyu');
UPDATE T
SET UserName = 'domainname\' + LEFT([E-MailAddress], CHARINDEX('#', [E-MailAddress])-1)
WHERE 'domainname\' + LEFT([E-MailAddress] , CHARINDEX('#', [E-MailAddress])-1) <> UserName
OR
UserName IS NULL;
SELECT *
FROM T;

Where is Access form data populating data from

I am currently trying to help a friend out with their invoicing Access database. I have rarely ever used Access and I am having problems figuring out the location of where the form (frmEntry) is pulling its data from. I did not create this setup so I am unsure of how it works. I am trying to figure out where the address information is being pulled from for when a customer is selected in a drop down on a form. I checked the query and it is only pulling the CustomerID and CustomerName, no address. The table does have address fields but none of the customers in the table have any listed, yet there address is populated along with their name in the form.
I do see where there is another form (frmCustomer) that has customer and there addresses but I am not sure if the other form is pulling from here, and if so, why can I not find the addresses in any of the tables or datasheet views?
Any direction would be very much appreciated. My end goal is to obtain the customer information (address etc) so that I can insert it into a new database that I am working on
Your data contains linebreaks and a combobox only shows one line per record.
To show the data you can replace the linebreaks in rowsource.
SELECT Replace([CustomerName],vbCrLf, " ") as CName FROM table
' vbCrLf is the VBA constant for linebreaks (Cr - Carrige Return, Lf - LineFeed)
This is poor database normalization (imagine you want to search for a customer name that is equal to a city, e.g. Paris). Each line should be a separate field in table (and Postcode too). If there is a linefeed for every data (e.g. no street -> empty line), you can just split the data into the new fields.
'Put this code in a module
'Split function
Public function splitCustomerName(ByVal strCustomerName as String, ByVal index as long) as String
Dim arrCustomerName As Variant ' or declare a fixed array if you know the number of lines
arrCustomerName = Split(strCustomername,vbCrLf)
splitCustomerName = arrCustomerName(index)
End Function
The query
UPDATE table SET newCustomerName = splitCustomerName([table].[CustomerName],0)
, newCustomerStreet = splitCustomerName([table].[CustomerName],1)
, newCustomerCity = splitCustomerName([table].[CustomerName],2);
Just create the necessary columns for name, street and city, then run the query.
If you delete the CostumerName column and rename the table (e.g. newTable) you can create a query with the oldname of the table, that behaves like your old table.
SELECT *
, newCustomerName & vbCrLf & newCustomerStreet & vbCrLf & newCustomerCity as CustomerName
FROM newTable

Muli-Option MS Access Reports

I am very new to MS Access and yet have been working (loosely) on a DB for a while. We have a DB that tracks membership. There is a table with all of the member info in there. When new and current customers are added, or pay for the current year, the info is applied to a 'PaidYear' column. For years now, I have been adding a query listing the current years' members and adding a report that displays the output of the query.
I would like to create a report where I could (using a drop-down maybe) select the active year and other options such as City, Company Name, Phone Number, etc. Is there any way to simply set this up? It has to be easy enough for my replacements to intuitively use. ie:
Member Report for [Choose Year] <-- Dropdown
[City] [Company] [Phone] [Select Option]<--- Extra Options for reporting
I have been playing with it for a while and while I can get the design set up, I can't set up the functionality. Thank you so much!!!
Yup, if you want to filter down your report, you can write a little bit of VBA to open your report with a filter (you don't need to use a parameter query for this. It may be more efficient to do this at the query execution level, but as far as i've noticed, the performance is the same to just run the full query and filter it at runtime of the report open (Access might actually just do this behind the scenes, again, I don't really know.
Anyways, lets get to it. Here's a code snippet that you can kind of use as a starting point and adapt.
Create a button that says 'Run Report', let's call it cmdRunReport
In the On Click event for that button, you will put some code. I'm just writing this up now, so I might have some syntax errors (don't have Access on this PC).
dim multiple as boolean
dim filtering as string
filtering = ""
if me.yearDropdown is not null then
filtering = filtering + "[myYearField] = " & me.yearDropdown
multiple = true
end if
if me.cityDroPDown is not null then
if multiple then
filtering = filtering + "AND [myCityField] = '" & me.cityDropdown & "'"
else
filtering = filtering + " [myCityField] = '" & me.cityDropdown & "'"
set multiple = true
end if
end if
if me.CompanyDropDown is not null then
if multiple then
filtering = filtering + "AND [myCompanyField] = '" & me.CompanyDropdown & "'"
else
filtering = filtering + " [myCompanyField] = '" & me.CompanyDropdown & "'"
set multiple = true
end if
end if
DoCmd.OpenReport "yourReport", acViewPreview, , filtering
This is the basis of what you can do. I may have a couple if syntax errors and concatenated the filtering string incorrectly (untested), but that's where you could start.
In english, it just looks at your form's dropdowns that you use to filter. It checks if they are not null, and then concatenates their values into the "filtering" string. This string is used as a parameter in your OpenReport method.
Hope this helps.

Why triggers try to insert NULL value when using a field from 'inserted' table?

I have to sync changes done in MSSQL with a remote MySQL database. The changes to be synced are adding invoices and users to the system. The remote server is not expected to be always reachable so I'm trying to set up a kind of log table for storing changes done in MSSQL.
Here is a fully working trigger for that:
CREATE TRIGGER [dbo].[dokument_insert]
ON [dbo].[dokument]
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO [bcg_ekodu].[dbo].[sync_stack] (event,sql, table_name, import_priority)
SELECT
'INSERT',
'INSERT INTO bills SET
date = "'+CONVERT(VARCHAR(19),dok_kuup,120)+'",
total = "'+CAST(kokkusum AS nvarchar)+'",
number = "'+RTRIM(dok_nr)+'",
created = "'+CONVERT(VARCHAR(19),savetime,120)+'",
rounded = "'+CAST(ymardus AS nvarchar)+'",
currency = "'+CAST(valuuta AS nvarchar)+'",
due_date = "'+CONVERT(VARCHAR(19),tasupaev,120)+'",
pk_joosep = "'+CAST(dok_kood AS nvarchar)+'",
joosep_hankija = "'+CAST(hankija AS nvarchar)+'";
UPDATE
bills, users, companies
SET
bills.user_id = users.id,
bills.imported = NOW()
WHERE
bills.imported IS NULL
AND companies.id = users.company_id
AND companies.pk_joosep = 10
AND bills.user_id = users.pk_joosep',
'bills',
'200'
FROM inserted
END
It inserts a row into 'sync_stack' table every time a row is inserted to 'dokument' table. The 'sql' column will contain an SQL to create the same kind of row in another (MySQL) database.
But this trigger is not working:
CREATE TRIGGER [dbo].[klient_insert]
ON [dbo].[klient]
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO [bcg_ekodu].[dbo].[sync_stack] (event,sql, table_name, import_priority)
SELECT
'INSERT',
'INSERT INTO users SET
username =10'+CAST(kl_kood as nvarchar)+',
password = NULL,
name ="'+LTRIM(RTRIM(kl_nimi))+'",
email ="'+CAST(LTRIM(RTRIM(kl_email)) as nvarchar)+'",
reference_no ="'+CAST(LTRIM(RTRIM(kl_viide)) as nvarchar)+'",
phone ="'+CAST(LTRIM(RTRIM(kl_tel1)) as nvarchar)+'",
logins ="'+CAST(0 as nvarchar)+'",
last_login = NULL,
created ="'+CONVERT(VARCHAR(19),savetime,120)+'",
updated = NULL,
deleted ="0",
address ="'+CAST(LTRIM(RTRIM(kl_aadr1)) as nvarchar)+'",
pk_joosep ="'+CAST(kl_kood as nvarchar)+'"',
'users',
'210'
FROM inserted
END
While the execution of the above SQL to create that trigger completes just fine, when I try to insert some rows to the 'triggered' table, I get the following error:
No row was updated.
The data in row 175 was not committed.
Error Source: .Net SqlClient Data Provider.
Error Message: Cannot insert the value NULL into column 'sql', table 'mydb.dbo.sync_stack'; column does not allow nulls. INSERT fails.
The statement has been terminated.
Correct the errors and retry or press ESC to cancel the change(s).
If I delete this trigger, this error does not occur.
If I insert just plain text for 'sql' column, it works as expected.
If I use any field from the inserted row, even just a text field, it fails again.
If I allow NULL values in 'sql' column, inserting rows succeeds but I get a NULL value in 'sql' column.
How to make the second trigger work as expected, too?
I suspect that at least one of the values from inserted that you are concatenating into your SQL statement is NULL. You can circumvent this by using COALESCE, e.g.
username =10'+COALESCE(CAST(kl_kood as nvarchar), '')+',
Of course you shouldn't be declaring nvarchar without specifying a length, right?
Bad habits to kick : declaring VARCHAR without (length)
Concatenating any value to NULL is NULL:
select 'test' + NULL
Results in null, you should use something like that for your columns:
select isnull(column, '')
This would result in an empty string.
