I have a column Transactions in a SQL Server table A.
I have around 1000 rows in that table, and in each row I have strings which has combination of
"#transaction --space of 3 characters---1" or "#transaction --space of 3 characters---0" these strings may be even repeated n number of times within the single row.
Result - I want to check all the
"#transaction --space of 3 characters---1" ones how many times repeated.
"#transaction --space of 3 characters---0" zeros how many times repeated.
I tried with queries such as
Select * from A where transaction like '%#transaction --space of 3 characters---1%
Select * from A where transaction like '%#transaction --space of 3 characters---0%
But these can't give me the desired result because there may be more number of above strings in single column.
Can anyone suggest how to count all these two strings with ending 1 and 0 separately ?
Thanks in advance
Try this
SELECT count (*) as [Count], 'Strings with 1' as [Comment]
FROM A
WHERE transaction like cast (#transaction as varchar(50)) +'???1%'
UNION ALL
SELECT count (*) as [Count], 'Strings with 0'
FROM A
WHERE transaction like cast (#transaction as varchar(50)) +'???0%'

I am trying to extract a set of numbers from comments like
"on april-17 transactions numbers are 12345 / 56789"
"on april-18 transactions numbers are 56789"
"on may-19 no transactions"
Which are stored in a column called "com" in table comments
My requirement is to get the numbers of specific length. In this case length of 5, so 12345 and 56789 from the above string separately, It is possible to to have 0 five digit number or more more than 2 five digit number.
I tried using regexp_replace with the following result, I am trying the find a efficient regex or other method to achieve it
select regexp_replace(com, '[^0-9]',' ', 'g') from comments;
regexp_replace
----------------------------------------------------
17 12345 56789
I expect the result to get only
column1 | column2
12345 56789
There is no easy way to create query which gets an arbitrary number of columns: It cannot create one column for one number and at the next try the query would give two.
For fixed two columns:
demo:db<>fiddle
SELECT
matches[1] AS col1,
matches[2] AS col2
FROM (
SELECT
array_agg(regexp_matches[1]) AS matches
FROM
regexp_matches(
'on april-17 transactions numbers are 12345 / 56789',
'\d{5}',
'g'
)
) s
regexp_matches() gives out all finds in one row per find
array_agg() puts all elements into one array
The array elements can be give out as separate columns.
I am pulling data and when I pull in the text field my results for the "distinct ID" are sometimes being duplicated when there are multiple results for that ID. Is there a way to concatenate the results into a single column/row rather than having them duplicated?
It looks like there are ways in other SQL platforms but I have not been able to find something that works in HANA.
Example
Select
Distinct ID
From Table1
If I pull only Distinct ID I get the following:
ID
1
2
3
4
However when I pull the following:
Example
Select
Distinct ID,Text
From Table1
I get something like
ID
Text
1
Dog
2
Cat
2
Dog
3
Fish
4
Bird
4
Horse
I am trying to Concat the Text field when there is more than 1 row for each ID.
What I need the results to be (Having a "break" between results so that they are on separate lines would be even better but at least a "," would work):
ID
Text
1
Dog
2
Cat,Dog
3
Fish
4
Bird,Horse
I see Kiran has just referred to another valid answer in the comment, but in your example this would work.
SELECT ID, STRING_AGG(Text, ',')
FROM TABLE1
GROUP BY ID;
You can replace the ',' with other characters, maybe a '\n' for a line break
I would caution against the approach to concatenate rows in this way, unless you know your data well. There is no effective limit to the rows and length of the string that you will generate, but HANA will have a limit on string length, so consider that.
I need some help on this one. I have a query that I need to make work but I need to limit it by the results of another query.
SELECT ItemID, ItemNums
FROM dbo.Tables
ItemNums is a varchar field that is used to store the strings of the various item numbers.
This produces the following.
ItemID ItemNums
1 1, 4, 5
2 1, 3, 4, 5
3 2
4 4
5 1
I have another table that has each item number as an INT that I need to use to pull all ItemIDs that have the associated ItemNums
Something like this.
SELECT *
FROM dbo.Tables
WHERE ItemNums IN (4,5)
Any help would be appreciated.
If possible, you should change your database schema. In general, it's not good to store comma delimited lists in a relational database.
However, if that's not an option, here's one way using a join with like:
select *
from dbo.Tables t
join dbo.SecondTable st on ', '+t.ItemNums+',' like '%, '+st.ItemNumId+',%'
This concatenates commas to the beginning and end of the itemnums to ensure you only match on the specific ids.
I personally would recommend normalizing your dbo.tables.
It would be better as:
ItemID ItemNums
1 1
1 4
1 5
2 1
etc.
Then you can use a join or a sub query to pull out the rows with ItemNums in some list.
Otherwise, it's going to be a mess and not very fast.
I have a column that has multiple numbers separated by a comma. Example for a row:
`numbers`:
1,2,6,66,4,9
I want to make a query that will select the row only if the number 6 (for example) is in the column numbers.
I cant use LIKE because if there is 66 it'll work too.
You can use like. Concatenate the field separators at the beginning and end of the list and then use like. Here is the SQL Server sytnax:
where ','+numbers+',' like '%,'+'6'+',%'
SQL Server uses + for string concatenation. Other databases use || or the concat() function.
You should change your database to rather have a new table that joins numbers with the row of your current table. So if your row looks like this:
id numbers
1 1,2,6,66,4,9
You would have a new table that joins those values like so
row_id number
1 1
1 2
1 6
1 66
1 4
1 9
Then you can search for the number 6 in the number column and get the row_id
I have a process that needs to select rows from a Table (queued items) each row has a quantity column and I need to select rows where the quantities add to a specific multiple. The mulitple is the order of between around 4, 8, 10 (but could in theory be any multiple. (odd or even)
Any suggestions on how to select rows where the sum of a field is of a specified multiple?
My first thought would be to use some kind of MOD function which I believe in SQL server is the % sign. So the criteria would be something like this
WHERE MyField % 4 = 0 OR MyField % 8 = 0
It might not be that fast so another way might be to make a temp table containing say 100 values of the X times table (where X is the multiple you are looking for) and join on that
