In table A -> Column X there is some data which has numbers, alphabets and special characters. Most of the records has single line of data but some of them has 2 or 3 lines of data.
1 this is a sample description of data 01/11/2017 # 123'~
Records with two lines of data
1 this is a sample description
2 of data 22/11/2017 #~ 12##'
I need to do a select query to get the records which has 2 lines of data in Column X of table A.
I use TOAD and the above mentioned sample data is from the Grid popup editor
thanks
You could select those rows that contain a new line (do not know your sample data, either chr(10) or chr(13)):
select *
from tableA
where instr(columnX, chr(10)) > 0;

I have a stream with a column with a variable number of semicolon deliminated values with a layout like
activities ticket_id
1;2;3 1
4;5 2
6; 3
7;8;9;10 4
. How can I get a new row for ever activity, like this
activity_id ticket_id
1 1
2 1
3 1
4 2
and so on?
In case I formatted this question wrong, here's an image
Simply use the "Split field to rows" step, use the Activities column as the field to split and ";" as the Delimeter.
Remenber that when you have a single value AND the delimeter, the step will output an additional row with an empty string. In this scenario the step will auto adjust the ticket_id column to repeat the values.
This solution in the screenshot below worked too
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 have a powerpivot table that contains 2 columns:
Column 1 contains strings.
Column 2 contains comma delimited strings.
I would like to be able to display all the rows from column 1 when rows from column 2 contains the selection from a filter or slicer. For example:
String Values
ABCD A,A,B
EFGH A,C
if A is selected I would display both rows, if B is selected I would display only row 1...etc.
I know I can split the records - but this is not practical for me - the above is only the top of the iceberg. VBA is out of the question since this will published in SharePoint. Anybody has an idea on how I could do that ? Thanks.
I found the solution in a blog from Javier Guillem:
http://javierguillen.wordpress.com/2012/02/10/simulating-an-approximate-match-vlookup-in-powerpivot/
If in my example the name of the table is "facts", I create a second unlinked table called dimRef that I populate with all possible values that I am interested to match: A,B,C,D...etc.
Then I define the measure M as:
M:=If ( Hasonevalue(facts[Values] ),
Calculate (
LASTNONBLANK (dimRef[String], 1 ),
Filter ( dimRef, SEARCH(dimRef[String],Values(facts[String]),1,0) > 0 )
)
)
I can then use the string column of the facts table and the measure in a pivot table and use dimRef as a selector. If filters the row as per the selection.
One small detail: the measure is not available in PowerView...Anybody knows why ?
I have text field in my pgsql DB which contains users identificators. One field can contain one or more ids separated by #. On saving numbers are imploded using PHP, so I can have for example:
Row 1: 3#36#66#33
Row 2: 5#56#33#55.
How should I prepare SQL query to select field with one or more ids without any ambiguity?
Example:
SELECT product FROM cms_product WHERE product_mod LIKE '3'
Both row 1 and 2 can be selected which I don't want. How I can fix it?
EDIT:
I will have to select all rows that contains user ID in this filed, for example:
UserId: 3
Field 1:
55#64#333#2
Field 2:
12#3#55#6423
Field 3;
654#33#11#98
Only field 2 should be selected.
Although you should really work to normalize your DB this is the answer to the posted question
select product
from cms_product
where '3' = any(regexp_split_to_array(product_mod, '#'))
I have data in one column that I want to separate into two columns. The data is separated by a comma if present. This field can have no data, only one set of data or two sets of data saperated by the comma. Currently I pull the data and save as a comma delimited file then use an FoxPro to load the data into a table then process the data as needed then I re-insert the data back into a different SQL table for my use. I would like to drop the FoxPro portion and have the SQL query saperate the data for me. Below is a sample of what the data looks like.
Store Amount Discount
1 5.95
1 5.95 PO^-479^2
1 5.95 PO^-479^2
2 5.95
2 5.95 PO^-479^2
2 5.95 +CA8A09^-240^4,CORDRC^-239^7
3 5.95
3 5.95 +CA8A09^-240^4,CORDRC^-239^7
3 5.95 +CA8A09^-240^4,CORDRC^-239^7
In the data above I want to sum the data in the amount field to get a gross amount. Then pull out the specific discount amount which is located between the carat characters and sum it to get the total discount amount. Then add the two together and get the total net amount. The query I want to write will separate the discount field as needed, see store 2 line 3 for two discounts being applied, then pull out the value between carat characters.
For SQL Server:
You can use ChardIndex(',',fieldname) in a sql statement to find the location of the comma and then Substring to parse out the first and second field.
For Oracle you can use a case statement like this in your select clause. Use one for each of the two discounts:
CASE WHEN LENGTH(foo.discount) > 0 AND INSTR(foo.discount,',') > 0 THEN
SUBSTR(foo.discount,1,INSTR(foo.discount,',',1,1)) ELSE foo.discount END AS discount_column_1
I finally figured out exactly how to separate the fields as I need them. Below is the code that breaks the discount field into two. I can now separate the fields as needed and insert the data separated into a temp table then use a similar set of code to pull out the exact amount enclosed by the carat characters. Thanks for the help in the two answers above. I used a combination of both to get exactly what I needed.
CASE LEN(X.DISCOUNT)-LEN(REPLACE(X.DISCOUNT,',',''))
WHEN 1 THEN SUBSTRING(X.DISCOUNT,1,CHARINDEX(',',X.DISCOUNT)-1)
ELSE X.DISCOUNT
END 'FIRST_DISCOUNT',
CASE LEN(X.DISCOUNT)-LEN(REPLACE(X.DISCOUNT,',',''))
WHEN 1 THEN SUBSTRING(X.DISCOUNT,CHARINDEX(',',X.DISCOUNT)+1,LEN(X.DISCOUNT)-CHARINDEX(',',X.DISCOUNT)+1)
ELSE ''
END 'SECOND_DISCOUNT'
This alternative solution uses LEFT and RIGHT functions for split the column.
select Store, Amount,
Discount1 = CASE
WHEN CHARINDEX(',',Discount) > 1 THEN LEFT(Discount, CHARINDEX(',',Discount)-1 )
ELSE Discount END,
Discount2 = CASE
WHEN CHARINDEX(',',Discount) > 1 THEN RIGHT(Discount, LEN(Discount) - CHARINDEX(',',Discount)-1 )
END
