So I have this table:
When I try with IsEmpty([Rented Books].[When Returned]) I don't get any results in the Query Design.
It also doesn't work with IsNull or Len.
Can somebody give me a hand on how to filter those?
Is Null in the Criteria Field did the job. I didn't do it correctly before that.

I have a column workId in my table which has values like :
W1/2009/12345, G2/2018/2345
Now a user want to get this particular id G2/2018/2345. I am using like operator in my query as below:
select * from u_table as s where s.workId like '%2345%' .
It is giving me both above mentioned workids. I tried following query:
select * from u_table as s where s.workId like '%2345%' and s.workId not like '_2345'
This query also giving me same result.
If anyone please provide me with the correct query. Thanks!
Why not use the existing delimiters to match with your criteria?
select *
from u_table
where concat('/', workId, '/') like concat('%/', '2345', '/%');
Ideally of course your 3 separate values would be 3 separate columns; delimiting multiple values in a single column goes against first-normal form and prevents the optimizer from performing an efficient index seek, forcing a scan of all rows every time, hurting performance and concurrency.
SELECT House__r.Name, House__r.House_Owner__r.person__r.Email__c, (SELECT Name, Total_Balance__c, Total_Expense__c FROM Expenses__r Where Type__c='Yearly' AND AND CALENDAR_YEAR(CreatedDate) = CALENDAR_YEAR(System.today() ) FROM Member__c
Error=> Unknown parsing error.
Kindly suggest what else can I do.
You have two 'AND' in a row. Also, if you are using query editor, you can't use System.today().
(on mobile, formatting will be poor, sorry)
SOQL supports only "field - operator - value_or_function” style for conditions. You try to make it "function - operator - another function", won't work.
For your particular scenario try with WHERE Created date = THIS_YEAR. It's a special literal, see https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql_select_dateformats.htm
More generic way would be to write what you need as a formula field, you could compare to YEAR(TODAY()). (that could be poor performance to filter by formula, often it results in full table scan, you would have to test, maybe add more filters using indexed columns...).
Or write it as WHERE CreatedDate >= :start AND CreatedDate <= :stop, put right bind variables for your range.
How would I take apart a column that contains string:
92873-987dsfkj80-2002-04-11
20392-208kj48384-2008-01-04
Data would look like this:
Filename Yes/No Key
Abidabo Yes 92873-987dsfkj80-2002-04-11
Bibiboo No 20392-208kj48384-2008-01-04
Want it to look like this:
Filename Yes/No Key
Abidabo Yes 92873-987dsfkj80-20020411
Bibiboo No 20392-208kj48384-20080104
whereby I would like to concat the dates in the end as 20020411 and 20080104. From the right side, the information is the same always. From the left it is not, otherwise I could have concatenated it. It is not an import issue.
As mentioned in the comments already, storing data like this is a bad idea. However, you can obtain the dates from those strings by using a RIGHT function like so:
SELECT RIGHT('20392-208kj48384-2008-01-04', 10)
Output:
2008-01-04
Depending on the SQLSERVER version you are using, you can use STRING_SPLIT which requieres COMPATIBILITY_LEVEL 130. You can also build your own User Defined Function to split the contents of a field and manipulate it as you need, you can find some useful examples of SPLIT functions in this thread:
Split function equivalent in T-SQL?
Assuming I'm correct and the date part is always on the right side of the string, you can simply use RIGHT and CAST to get the date (assuming, again, that the date is represented as yyyy-mm-dd):
SELECT CAST(RIGHT(YourColumn, 10) As Date)
FROM YourTable
However, Panagiotis is correct in his comment - You shouldn't store data like that. Each column in the database should hold only a single point of data, be it string, number or date.
Update following your comment and the updated question:
SELECT LEFT(YourColumn, LEN(YourColumn) - 10) + REPLACE(RIGHT(YourColumn, 10), '-', '')
FROM YourTable
will return the desired results.
Have been trying to understand this for a while ...
How can I specify NOT clause in the following query?
{!field f=schedule op=Intersects}[2016-08-26T12:30:00Z TO 2016-08-26T18:30:00Z]
{!field f=schedule op=Contains}[2016-08-26T12:30:00Z TO 2016-08-26T18:30:00Z]
Like, without LocalParams, we can specify -DateField:[2016-08-26T12:30:00Z TO 2016-08-26T18:30:00Z] to get an equivalent NOT clause. But, I need a NOT Contains Date Range query.
I have tried a few options but I end up getting parsing errors. Surely there must be some obvious way I am missing.
Assume that I had the following t-sql:
select * from customer where contains(suburb, '"mount*"').
Now it brings back both: "Mount Hills" and "Blue Mountain". How do I strict it to search only the very beginning of the word which in this case is only "Mount Hills"?
thanks
'contains' is used for exactly that. Use
select * from customer where charindex('mount', suburb)=1
or
select * from customer where suburb like 'mount%'
but that's slower.
Your query works correctly, you asked server "give me all record where ANY word in column 'suburb'" starts with 'mount'.
You need to be more specific what are you trying to accomplish. Match beginning of the entire value stored in column? LIKE is your friend then.
