could someone please help me to write a query to substitute hyphens in rails DB field with space?
For eg:
If I have a field called 'name' in a table User having a value 'asdc-sd bc', and want to remove special characters like '-' and replace it with space to match with a given name 'asdc sd bc'.
I tried using lower to convert the name to lowercase but am not able to find out how to substitute the hyphens with space. Please help!
You can use SQL REPLACE function to replace - with spaces(' ').
For example, if you are querying on name column of User model, you can write your query like below:
query_str = 'asdc sd bc'
User.where("REPLACE(name, '-', ' ') = ?", query_str)
I have a list of data with a title column (among many other columns) and I have a Power BI parameter that has, for example, a value of "a,b,c". What I want to do is loop through the parameter's values and remove any rows that begin with those characters.
For example:
Title
a
b
c
d
Should become
Title
d
This comma separated list could have one value or it could have twenty. I know that I can turn the parameter into a list by using
parameterList = Text.Split(<parameter-name>,",")
but then I am unsure how to continue to use that to filter on. For one value I would just use
#"Filtered Rows" = Table.SelectRows(#"Table", each Text.StartsWith([key], <value-to-filter-on>))
but that only allows one value.
EDIT: I may have worded my original question poorly. The comma separated values in the parameterList can be any number of characters (e.g.: a,abcd,foo,bar) and I want to see if the value in [key] starts with that string of characters.
Try using List.Contains to check whether the starting character is in the parameter list.
each List.Contains(parameterList, Text.Start([key], 1)
Edit: Since you've changed the requirement, try this:
Table.SelectRows(
#"Table",
(C) => not List.AnyTrue(
List.Transform(
parameterList,
each Text.StartsWith(C[key], _)
)
)
)
For each row, this transforms the parameterList into a list of true/false values by checking if the current key starts with each text string in the list. If any are true, then List.AnyTrue returns true and we choose not to select that row.
Since you want to filter out all the values from the parameter, you can use something like:
= Table.SelectRows(#"Changed Type", each List.Contains(Parameter1,Text.Start([Title],1))=false)
Another way to do this would be to create a custom column in the table, which has the first character of title:
= Table.AddColumn(#"Changed Type", "FirstChar", each Text.Start([Title],1))
and then use this field in the filter step:
= Table.SelectRows(#"Added Custom", each List.Contains(Parameter1,[FirstChar])=false)
I tested this with a small sample set and it seems to be running fine. You can test both and see if it helps with the performance. If you are still facing performance issues, it would probably be easier if you can share the pbix file.
This seems to work fairly well:
= List.Select(Source[Title], each Text.Contains(Parameter1,Text.Start(_,1))=false)
Replace Source with the name of your table and Parameter1 with the name of your Parameter.
I have a data set with 100+ variables for each of many people.
I have two variables for the person's name: lastname and firstname.
How can I create an output file using the names (i.e., the values of the variables lastname and firstname)?
I would like to do a split file by lastname firstname and export the data for each person into a text file that uses the person's name as the file name.
Below is what my spss command file is doing now. How can I get the command file to spit out separate files for each person?
SORT CASES BY lastname firstname .
SPLIT FILE BY lastname firstname .
PRINT / " ".
PRINT /
"===================================================================".
PRINT / "Report of Selected Responses from the".
PRINT / "Survey Form Document".
Print /"Responses for Candidate: " .
Print / firstname.
Print / lastname.
PRINT /
"===================================================================".
DO IF (Q1.5month EQ "" OR sysmis(q1.5day) OR sysmis(q1.5year) ).
Print
/ "1.5. Some or all of date of birth left blank".
END IF.
[More such print statements.]
EXECUTE.
SPLIT FILE OFF.
First create an empry string variable and populate it:
String firstname_lastname (A100).
Compute firstname_lastname=concat(rtrim(firstname),"_",rtrim(lastname)).
EXECUTE.
Then go to Data menu, Split into files, select your new firstname_lastname variable as the split variable, and.under options select "value labels". Pick a folder and you are done. Maybe click paste, to have everything in syntax 😉
Assume a Node "Properties". I am using "LOAD CSV with headers..."
Following is the sample file format:
fields
a=100,b=110,c=120,d=500
How do I convert fields column to having a node with a,b,c,d and 100,110,120,500 respectively as the properties of the node "Properties"?
LOAD CSV WITH HEADERS FROM 'file:/sample.tsv' AS row FIELDTERMINATOR '\t'
CREATE (:Properties {props: row.fields})
The above does not create individual properties, but sets a string value to props as "a=100,b=110,c=120,d=500"
Also, different rows could have different set of Key values. That is the key needs to be dynamic. (There are other columns as well, I trimmed it for SO)
fields
a=100,b=110,c=120,d=500
X=300,y=210,Z=420,P=600
...
I am looking for a way to not split this key-value as columns and then load. The reason is they are dynamic - today it is a,b,c,d it may change to aa,bb,cc,dd etc.
I don't want to keep on changing my loader script to recognize new column headers.
Any pointers to solve this? I am using the latest 3.0.1 neo4j version.
First things first: Your file format currently defines a single header/property: fields:
fields
a=100,b=110,c=120,d=500
Since you defined a tab as field terminator, that entire string (a=100,b=110,c=120,d=500) would end up in your node's props property:
To have properties loaded dynamically: First set up proper header:
"a","b","x","y"
1,2,,
,,3,4
Then you can query with something like this:
LOAD CSV WITH HEADERS FROM 'file:///Users/David/overflow.csv' AS row
CREATE (:StackOverflow { a:row.a, b:row.b,x:row.x,y:row.y})
Then when you run something like:
match(so:StackOverflow) return so
You'll get the variable properties you wanted:
I am trying to get answer for the last few weeks. I want to give a textfield to users in the app and ask them to enter a id number and this number will be checked with the uploaded csv file columns. If it matches then display an alert saying that its found a match or else it doesn't.
A csv file is basically a normal file in which items are separated by commas.
For example:
id,name,email
1,Joe,joe#d.com
2,Pat,pat#d.com
To get the list of IDs stored in this csv files, simply loop through the lines, and grab the first item after splitting the string (use comma to split)
id = line.split(",").get(0); // first element ** Note this depends on what language you're using
Now, add this id to a collection of ids you are storing, like in a list.
IDs.add(id);
When you take the user input, all you need to do is to check if the id is in your list of ids.
if (IDs.contains(userId)) { print "Found"; }
