I am back again with a small problem. Hope i get something here.
I am working on a report, SQL Server Reporting Services 2012 and Database is Sybase ASE.
One of my report parameter can have multiple values. Let's name the parameter as #Fruit. It can have multiple values. So if the user selects Apple and Mango from the list, it should pass to the query at backend.
The parameter gives the values as : Apple,Mango
Now i need to pass it to the query in the below way.
SELECT
COLUMN1,
COLUMN2,
COLUMN3
FROM DBO.TABLE_NAME
WHERE COLUMN2 IN ('Apple','Mango')
Problem: I am able to pass a single fruit name at a time. But not able to pass more than one value. I did a bit research and found it's problem with Sybase. It cannot take multiple value.
I believe someone might have found a work around. Just need to get it working.
Thanks In Advance.!
you can create a comma separated string from the list using join in a expression:
strFruits= Join(Parameters!fruits.Value,",")
then your where clause would look like:
WHERE CHARINDEX(',' + COLUMN2 + ',' , ',' + #strFruits + ',')>0
the ',' added at the beginning and end of the strings are to make sure the search string is found even if it is located at beginning or end of the comma separated list.

The environment I am currently working in is Snowflake.
As a matter of data sensitivty, I will be using pseudonyms for my following question.
I have a specific field in one of my tables called FIELD_1. The data in this field is structured as such:
I am trying to figure out how to automatically extract from my FIELD_1 the output I have in FIELD_2.
Does anyone have any idea what kind of query I would need to achieve this? Any help would be GREATLYappreciated! I am really quite stuck on this problem.
Thank you!
You seem to want everything up to the first four numbers. Then to replace the underscores with spaces. If so:
select replace(regexp_substr(field_1, '^[^0-9]*[0-9]{4}'), '_', ' ')
Or alternatively, if you want the first three components separated by underscores:
select replace(regexp_substr(field_1, '^[^_]+_[^_]+_[0-9]{4}'), '_', ' ')
If the data is as simplistic in reality as you've described here, you can use a variable-length LEFT() function in conjunction with REPLACE() to get the desired output:
SELECT FIELD_1, REPLACE(LEFT(FIELD_1, LEN(FIELD_1)-10),'_',' ') AS FIELD_2
FROM table_name

i've got a problem with transferring "real-World" data into my schema.
It's actually a "project" for my Database course and they gave us ab table with dog race results. This Table has a column which contains the name of the Dog (which itself consists of the actuall name and the name of the breeder) and informations about the Birthcountry, actual living Country and the birth year.
Example filed are "Lillycette [AU 2012]" or "Black Bear Lee [AU/AU 2013]" or "Lemon Ralph [IE/UK 1998]".
I've managed it to get out the first word and save it in the right column with split_part like this:
INSERT INTO tblHund (rufname)
SELECT
split_part(name, ' ', 1) AS rufname,
FROM tblimport;
tblimport is a table where I dumped the data from the csv file.
That works just as it should.
Accessing the second part of the Name with this fails because sometimes there isn't a second part and sometimes times there second part consists of two words.
And this is the where iam stuck right now.
I tried it with substring and regular expressions:
INSERT INTO tblZwinger (Name)
SELECT
substring(vatertier from E'[^ ]*\\ ( +)$')AS Name
FROM tblimport
WHERE substring(vatertier from E'[^ ]*\\ ( +)$') != '';
The above code is executed without errors but actually does nothing because the SELECT statement just give empty strings back.
It took me more then 3h to understand a bit of this regular Expressions but I still feel pretty stupid when I look at them.
Is there any other way of doing this. If so just give me a hint.
If not what is wrong with my expression above?
Thanks for your help.
You need to use atom ., which matches any single character inside capturing group:
E'[^ ]*\\ (.+)$'
SELECT
tblimport.*,
ti.parts[1] as f1,
ti.parts[2] as f2, -- It should be the "middle part"
ti.parts[3] as f3
FROM
tblimport,
regexp_matches(tblimport.vatertier, '([^\s]+)\s*(.*)\s+\[(.*)\]') as ti(parts)
WHERE
nullif(ti.parts[2], '') is not null
Something like above.
I want to update a column that contains a string like 12,43,433 I want to only replace 43 with another number say 54 so that the column value becomes 12,54,433.
How can I do that??
You can use REPLACE() function like this:
UPDATE YourTable a
SET a.StringColumn = REPLACE(a.StringColumn,',43,',',54,')
WHERE a.StringColumn like '%,43,%'
Storing lists as strings is a very bad idea. SQL has a great data structure for storing lists. It is called a table, not a string. The proper way to store lists is to use a junction table.
Sometimes we are stuck with other people's really bad design decisions. If so, you can do:
update t
set col = trim(replace(',' || col || ',', ',43,', ',54,'), ',')
where ',' || col || ',' like '%,43,%';
Notes:
This works regardless of where the "43" appears in the string (including at the beginning and end).
This maintains the format of the string with no commas at the beginning and end.
This only attempts to update rows that have the particular elements in the list.
Use of such a query should really be a stopgap while you figure out how to fix the data structure.
I have column store_name (varchar). In that column I have entries like prime sport, best buy... with a space. But when user typed concatenated string like primesport without space I need to show result prime sport. how can I achieve this? Please help me
SELECT *
FROM TABLE
WHERE replace(store_name, ' ', '') LIKE '%'+#SEARCH+'%' OR STORE_NAME LIKE '%'+#SEARCH +'%'
Well, I don't have much idea, and even I am searching for it. But may be what I know works for you, You can achieve this by performing different type of string operations:
Mike can be Myke or Myce or Mikke or so on.
Cat an be Kat or katt or catt or so on.
For this you should write a function to generate number of possible strings and then form a SQL Query using all these, and query the database.
A similar kind of search in known as Soundex Search from Oracle and Soundex Search from Microsoft. Have a look of it. this may work.
And overall make use of functions like upper and lower.
Have you tried using replace()
You can replace the white space in the query then use like
SELECT * FROM table WHERE replace(store_name, ' ', '') LIKE '%primesport%'
It will work for entries like 'prime soft' querying with 'primesoft'
Or you can use regex.
Here is my issue:
I have a column with the following data in an sql column:
Answers
=======
1:2:5: <--- notice my delimiter
I need to be able to break up the digits into a result set that i can join against a lookup table such as
Answers_Expanded
=======
1 apple
2 pear
3 cherry
4 mango
5 grape
and return
Answers
=======
apple pear grape
Any such way?
Thanks!
This is a bit of a hack (the LIKE, the XML PATH, and the STUFF), and it assumes that you want the answers ordered by their ID as opposed to matching up with the original order in the multivalued column...
But this gives the results you're looking for:
SELECT STUFF((
SELECT ' ' + ae.Answer
FROM
Answers_Expanded ae
JOIN Answers a ON ':' + a.Answers LIKE '%:' + CAST(ae.ID AS VARCHAR) + ':%'
ORDER BY ae.ID
FOR XML PATH(''))
, 1, 1, '') AS Answers
Sql Fiddle
This works because:
Joining with LIKE finds any Answer_Expanded rows that match the multivalued column.
XML PATH simulates a group concatenation... and allows for ' ' to be specified as the delimiter
STUFF removes the leading delimiter.
This blog post has a good example of a user defined function that will return a table with the values from your delimited string in a column. You can then join that table to your Answers_Expanded table to get your value.
This works fine if you are parsing reasonably short strings, and if you are doing it as a one time thing, but if you have a table with your answers stored in a column like that, you don't want to be running this on the whole table as it will be a large performance hit. Ideally you'd want to avoid getting delimited strings like this in SQL.
i would suggest that you save your answers in a way that one cell has only one number...not multible information in one cell. (violation of the 1st normal form).
otherwise you better use some higher sql language such as T-SQL.
