So I followed the directions that I was given to me in my live lecture word for word and also researched this in my textbook and I've done everything (So I think) properly but I keep getting a error Which I have looked up to see what it means and it didn't help me at all and I've been working on it for a whole day so I'm reaching out to you guys to see if you can see my mistake anywheres in my code
This is the question that I am trying to complete:
Using the BOOK_CUSTOMER table and the NVL function, create a query that will return a list containing the customer number, first name, last name, and the characters ‘NOT REFERRED’ if the customer was not referred by another customer. Give the derived column an alias of REFERRED BY. Do not list any customers that were referred by another customer.
MY CODE =
SELECT CutomerID, FirstName, LastName,
NVL(TO_CHAR(Referred), 'Not Referred'))
FROM Book_Customer;
I also realize that I haven't completed the whole question. I'm just trying to get my NVL to work first and then go onto the Alias and the last part of the question because I do not know how to do either of those yet, any tips on that would be greatly appreciated as well
There's an extra (unmatched) closing paren in your SQL text, and that's going to throw a syntax error.
NVL(TO_CHAR(Referred), 'Not Referred'))
^
There's no matching opening paren for that last paren.
To assign an alias to an expression in the SELECT list, follow the expression with the keyword AS and an alias.
SELECT t.foo AS bar
The resultset will contain a column named bar.
SELECT b.CustomerID
, b.FirstName
, b.LastName
, NVL(TO_CHAR(b.Referred),'Not Referred') AS ReferredBy
FROM Book_Customer b
WHERE b.Referred IS NULL
I finally figured it out! The proper code was:
SELECT CustomerID, FirstName, LastName,
NVL(TO_CHAR(Referred), 'Not Referred') AS "Referred By"
FROM Book_Customer
WHERE Referred IS NULL;
Thank you everyone for all your helpful comments that helped me figure out this problem.

I am trying to match a list of range with certain criteria in a google spreadsheet. I am using DGET function for the same. Everything is working fine but the problem comes when there are many entries that contain the whole string and I receive "More than one match found in DGET evaluation.".
For the better understanding look below:
Sheet "Form Responses 1":
B
-------
Ronald
Ronaldo
Ronaldinho
Rebarto
Matching sheet entries:
A
------
Ronald
Rebarto
Juhino
My Formula is:
=DGET('Form Responses 1'!B:H,"Date",{"Email Address","Logging In or Logging out ?","Date";A2,$B$1,$H$1})
Now the problem is Ronald is matching with "Ronald","Ronaldo" and "Ronaldinho" and I am receiving the error which says "multiple entries found".
How do we solve this?
I solved the problem by Concatenating a constant variable before and after the name. For example Ronaldo becomes mRonamdom and Ronald becomes mRonaldm. This makes the Names Unique and solves the problem.
If you don't want to modify the data but to fix the formula so it doesn't get confused with similar entries in your database parameter you can add a character to the criteria field of the dget function as shown below (I'm using an '=' sign concatenated to the value I want to match with in the database parameter)
=dget(database!$A$1:$B$11,$M$1,{"columnName";"="&F2})
where
A1:B11 is my database
M1 is the matching column name
and "="&F2 is the field with the caracter I chose that I want to match with to retrieve values from the matching database column, now even if the there are more than one matches found (becuase matching substrings"), the addition of the caracter contatenated with the matching value, should take care of the in-accurate error.
I am currently using this formula to get all the data from everyone whose first name is "Peter", but my problem is that if someone is called "Simon Peter" this data is gonna show up on the formula output.
=QUERY('Data'!1:1000,"select * where B contains 'Peter'")
I know that for the other formulas if I add an * to the String this issue is resolved. But in this situation for the QUERY formula the same logic do not applies.
Do someone knows the correct syntax or a workaround?
How about classic SQL syntax
=QUERY('Data'!1:1000,"select * where B like 'Peter %'")
The LIKE keyword allows use of wildcard % to represent characters relative to the known parts of the searched string.
See the query reference: developers.google.com/chart/interactive/docs/querylanguage You could split firstname and lastname into separate columns, then only search for firstnames exactly equal to 'Peter'. Though you may want to also check if lowercase/uppercase where lower(B) contains 'peter' or whitespaces are present in unexpected places (e.g., trim()). You could also search only for values that start with Peter by using starts with instead of contains, or a regular expression using matches. – Brian D
It seems that for my case using 'starts with' is a perfect fit. Thank you!
I want to create a TFS query to show all the Work Items of type "Issue" & "Requirement" created by person "A" & "B".
I have the below query but it doesn't give me the expected results:
Can someone please tell me what changes I need to make?
Change the Created By clauses to "Or" and grouping them together. That should give you your expected results. Like this:

Thank you !
Adding details as suggested in the comments by #ios82
The main thing I had to do was to use the "grouped clauses" as described in the link above.
You do that by selecting the parameters you want to group by, right clicking and selecting the option of "Group Clauses". Screenshot below.
In my case I grouped both the "work item type" clauses together & the "created by". clauses together.
Also, the Condition on the CreatedBy (B) Should be changed to "OR" instead of "AND". That did it !!
I wanna update my table for all persons whoes activity lasted toooo long. The update should correct one time and for the subsequent rows I need to deal with new result. So thought about something like
UPDATE summary_table st
SET st.screen_on=newScreenOnValue
st.active_screen_on=st.active_screen_on-(st.screen_on-newScreenOnValue) --old-value minus thedifference
FROM (
SUB-SELECT with rowid, newScreenOnValue ... JOIN ... WHERE....
) nv
WHERE (st.rowid=nv.rowid)
I know that I can update the first and the second value directly, by rerunning the same query. But my problem is the costs of the subselect seems quite high and therefore wanna avoid a double-update resp. double-run of the same query.
The above SELECT is just a informal way of writting what I think I would like to get. I know that the st doesn't work, but I left it here for better understanding. When I try the above statement I always get back a SyntaxError at the position the FROM ends.
This can be achieved as follows:
UPDATE summary_table st
SET (st.screen_on, st.active_screen_on) =
((SELECT newScreenOnValue, st.active_screen_on-(st.screen_on-newScreenOnValue)
FROM ...
JOIN...
WHERE..))
[WHERE if any additional condition required];
The above query works perfectly fine on informix tried and tested until you make any errors in the FROM, JOIN, WHERE clauses.
Cheers !
Syntax error because a comma is missing between the first and second columns you're updating.
Never use ROWID's, they're volatile and also not used by default with IDS, unless you specify so.
Why are you using a subquery?
Symptoms:
Searching for a single word (i.e. "Snap") works
Searching for another word contained in the same field (i.e. "On") also works
Searching for "Snap On" at the same time returns 0 results, even though it shouldn't.
The setup:
SQL Server 2008 R2 with Advanced Features
nopCommerce 3.0
Things I have done:
I added the Product.MetaKeywords column to the full text search catalog
I added a bit into the Stored Procedure that performs the search to search through the MetaKeywords
Now the nopCommerce boards are fairly slow, but I'm positive the problem is within the SQL Stored Procedure anyway, so I figured I would ask for some SQL Server help here, even if you aren't familiar with the nopCommerce web app, you may have some information you can help me with.
The stored procedure in question is too large to post entirely here, but basically it dynamically adds "OR" or "AND" in between the keyword searches to generate the phrase used in a Contains clause. It selects through several unions various searchable fields by using Contains.
Here is the bit I added into the stored procedure
SET #sql = #sql + '
UNION
SELECT p.Id
FROM Product p with (NOLOCK)
WHERE '
IF #UseFullTextSearch = 1
SET #sql = #sql + 'CONTAINS(p.[MetaKeywords], #Keywords) '
ELSE
SET #sql = #sql + 'PATINDEX(#Keywords, p.[MetaKeywords]) > 0 '
#Keywords, at this point, if I am reading the procedure correctly, has a value of: "Snap* AND On*"
I don't understand why my query of "Snap On" returns 0 results, but "Snap" and "On" individually work fine.
The minimum search length is set to 1, so it's not that.
I should add that searching for "Snap* OR On*" works, but I cannot use OR because then searching for "Snap On" will also return "Snap Dragon" and other unrelated things.
--EDIT--
The problem wasn't any of that. I got some advice elsewhere and the problem was actually the stoplist. I managed to fix my issue simply by changing the stoplist on the product table from <system> to <off>.
To do this, follow these steps.
browse to your table in SQL Server management studio
Right click on the table and select "Full-Text Index"
Select "Properties" under "Full-Text Index"
In the "General" Tab, change "Full-Text Index Stoplist" to <off>
I had to do it this way because I was unable to get the transact SQL to work. It kept telling me there was no such object as the table I was attempting to modify. If anyone can provide any insight on how the Alter fulltext index statement works, I'm interested, because I was following the example on the MSDN page to the T and it just kept telling me there was no such object named Product.
The asterisk is not a plain old wildcard. If you are using it anywhere other than at the end of a search term, you're probably not using it correctly. See answers to a similar question
SQL Contains Question
In your case, each search term must be quoted separately. See this example from the docs http://technet.microsoft.com/en-us/library/ms187787(v=sql.90).aspx
SELECT Name
FROM Production.Product
WHERE CONTAINS(Name, '"chain*" OR "full*"');
