How do I concat two columns with new line in between in Netezza not SQL?
Use the CHR function, and get the argument value from https://www.asciitable.com/ depending on what you mean by ‘new line’. Unix/windows/Mac unfortunately has different definitions, but let’s go with the Unix style:
Select
FNAME,
LNAME,
FNAME||chr(10)||LNAME
FROM YOURTABLE

I'm creating a SSIS package which has two variables that is going to assign values into another SQL Command variable. The data source is an ODBC connector and the destination is an OLEDB connector.
Variables name:
vPurchaseType (multiple values)
vTransactionDate (single value)
vPSourceQuery (SQL statement that is receive the others two variables)
One variable is a single row, this one it's working. The other variable is multiple values that is going to be ingested in a IN clause. But I'm not being able to pass multiple values in this one, I already tried Single row or Full result set but also doesn't work.
First variable result (vPurchaseType):
Query example:
SELECT Head FROM TableB
Head
12
9C
AA
The second variable must be between single quotes in order to work.
Second variable result (vTransactionDate):
Query example:
SELECT Head FROM TableA
Head
2020-01-01
Third variable:
SELECT
ColA,
ColB,
ColC,
ColD
FROM TableC
WHERE ColC >= '"+ #[User::vTransactionDate] + "'
AND ColD IN ("+ #[User::vPurchaseType] +")
My package:
Basically I'm using the solution of this article from MyTecBits - SQL Server: Concatenate Multiple Rows Into Single String, and applying that to my variable vPurchaseType, and receiving the values as Single Row. But I had to change the query a little bit, by using the function CAST AS VARCHAR (4000) to accept all the data from my column.
After that I changed my Data Flow, and did the swap from OLEDB Destination to ADO Net Destination, I also had to mark the option ValidadeExternalMetadata as False, and that's it! Now is working.
I want to create a report in MS SQL Server BIDS (SSMS and Visual Studio). The user would enter a list of email addresses as a parameter. So #pEmails would be 'foo#bluh.com', 'bar#meh.org', etc. These email addresses may or may not be in a table.
I can simply do:
and Table.Email in (#pEmails)
and that works, except I need to return the email address if it's NOT found as well. So the results would be something like:
|email |found in table|
|------------|--------------|
|foo#bluh.com| Y |
|bar#meh.org | N |
I was thinking I could take the list of values entered as the #pEmails parameter and create a temp table with them, which I could then left join with, but my attempts to do so have not worked out.
declare #pEmails table (EmailAddress varchar(255));
insert into #pEmails values (#ReportParameter1);
select
*
from
#pEmails
The above works if only a single value is put into #ReportParameter1, but not if multiples are in it.
I am using SQL Server 2008. Any suggestions on how best to proceed?
As has been stated, you need some kind of split function, for analysis on the performance of various methods Split strings the right way – or the next best way is an excellent read. Once you have your function, you then need to define your query parameter as a string, rather than a table:
So your query would actually become:
DECLARE #pEmails TABLE (EmailAddress varchar(255));
INSERT #pEmails (EmailAddress)
SELECT Value
FROM dbo.Split(#pEmallString);
Then go to your dataset properties, and instead of passing the multivalue parameter #pEmails to the dataset, instead create a new one #pEmailString, and set the value as an expression, which should be:
=Join(Parameters!pEmails.Value, ",")
This turns your multivalue parameter into a single comma delimited string. It seems pretty backwards that you need to convert it to a delimited string, only to then split it in SQL, unfortunately I don't know of a better way.
Here are some learnings on this topic (standing on the shoulders of the information elsewhere in this thread).
Set a parameter (select 'multiple values' checkbox):
InputList
Establish dataset query:
SELECT *
INTO #InputTemp
FROM STRING_SPLIT(#InputListJoin, ',')
SELECT value as ValueName
FROM #InputTemp T2
WHERE NOT EXISTS (
SELECT MyValue
FROM MyTable T1
WHERE T1.MyValue = T2.value
)
Establish dataset parameters:
Name: #InputList | Value: [#InputList]
Name: #InputListJoin | Value(expression): =Join(Parameters!InputList.Value,",")
The element names can be changed as needed.
Somewhat on topic, other details that might be helpful:
[#InputList.IsMultiValue] --> true/false whether your parameter is multi-value (not whether there are multiple values)
[#InputList.Count] --> count of items in input list (excludes blank lines)
=Parameters!InputList.Value(2) --> return third value from list (counting from zero)
I am going round in circles with a bit of SQL and would appreciate some help.
I've looked up creating temp tables, nested Select statements (where advice seems to be to avoid these like the plague) and various uses of Case statements but I can't seem to find a solution that works. I'd say I'm beginner level for SQL.
I have a table with 10 relevant records. The query that works to return all the relevant entries in the table is:
SELECT
TblServAct.ServActId
,TblServAct.ServActName
FROM TblServAct
WHERE TblServAct.ServActExclude IS NULL
ORDER BY TblServAct.ServActName
Here is where I run into problems:
When the parameter (#YESNOActivity) = Yes, I want all the rows in the table to be returned. I have managed to do this with a CASE statement
...however when the parameter (#YESNOActivity) = No, I want ONLY ONE row to be returned which doesn't actually exist in the table (and should not be inserted into the actual table). The values that I need to insert are: ServActId = 101 and ServActName = 'Select YES in Parameter2 to filter by Service Activity'
For background, the reason I am doing this is because I have found SSRS report parameters to be especially difficult to conditionally format. I want to use the dataset above to return a message in a parameter (lets call it parameter2) that the user needs to select yes in (#YESNOActivity) in order to see the full selection list in parameter2.
If I can get this to work I can see lots of potential for re-use so all advice appreciated
Thanks

I believe this should do the job, just include your parameter in the WHERE clause and UNION it with your own row of data.
SELECT
TblServAct.ServActId
,TblServAct.ServActName
FROM TblServAct
WHERE TblServAct.ServActExclude IS NULL
AND #YESNOActivity = 'Yes'
UNION ALL
SELECT
ServActId = 101
,ServActName = 'Select YES in Parameter2 to filter by Service Activity'
WHERE #YESNOActivity = 'No'
ORDER BY TblServAct.ServActName
One way is to use this query:
SELECT
TblServAct.ServActId
,TblServAct.ServActName
FROM TblServAct
WHERE TblServAct.ServActExclude IS NULL
AND 'Yes' = #YESNOActivity
UNION ALL
SELECT
101 AS ServActId
,'Select YES in Parameter2 to filter by Service Activity' AS ServActName
WHERE 'No' = #YESNOActivity
ORDER BY TblServAct.ServActName
Another way would be to create two data flows and use your variable in a constraint to send the processing to one or the other.
A third way would be to put an expression on the SQL command and use your variable to switch between two SQL statements.
I am trying to use DATEADD function in a derived column transformation but it seems the expression i am using is wrong. Initially, i was using this in my SQL query which works fine but i want to use it now in a derived column so i can transform the date value before i bring it into my table. Here is the sql i was using:
select DATEADD(day,myDate,'19600101') as NewDate from myTable
but i want to use it now in derived column so i am replacing the column and using this in the expression:
DATEADD("day", myDate, "19600101" )
I just had the same problem, here is the fix:
instead of:
DATEADD("day", myDate, "19600101" )
try:
DATEADD("day", (DT_DBDATE)myDate, (DT_DBDATE)"19600101")
This will return a database datestamp, which can be cast back to a string if needed. In my case, I am converting from Epoch time (milliseconds since 1/1/1970), so I need this:
DATEADD("s",(DT_I8)[Index Time],(DT_DBTIME)"1/1/1970")
Please see the documentation for dateadd: http://msdn.microsoft.com/en-us/library/ms141719.aspx. I am not sure what you are tryinmg to do with this expression. If you wanted to add one day then it would be:
select DATEADD(d,1,myDate) as NewDate from myTable
If you wanted to subtract one day then it would be:
select DATEADD(d,-1,myDate) as NewDate from myTable
Please explain what you are trying to do. I do not think the first arguement should be inside double quotes. Also "day" is not allowed according to the remarks section in my link.
I know how to use CONVERT function in SELECT statement to change the format of the Date column:
SELECT
StationID
, CONVERT(varchar, [Date], 101) as Date
, Value
FROM my_table
But I was wondering if I can set the date format in general before running the SELECT statement, when I don't know the name of the date column in the following SELECT statement:
SELECT * from FROM my_table
Is any SET statement or other T-SQL that I can run before my SELECT statement so that I can change the Date format temporarily?
Thank you
No.
In particular, any date columns which you select are not actually formatted at all, but are instead returned down the wire as an actual piece of date data in a binary "format" which is used for dates. If you are seeing them formatted, it's because your client (either management studio or some other tool) is converting them to strings to display.
When you use SELECT *, there is obviously no way to tell SQL Server to do any conversions on any particular columns, so the data is going to be returned in whatever the data types of the underlying query returns. So regardless of whether your data types are really date or not, no manipulation is going to happen at that point anyway.
I'm pretty sure there's no way to do what you're asking. However, there are ways to format the date string when you output it using your programming language.
