How to assign ID to multiple rows based on a value in 1 column in 1 row duplicating a value in a DIFFERENT column in a d

Hope this helps When a call is placed to an emergency line, it is given a CallNo (a unique to the event); however, sometimes, multiple calls are placed and different call takers accidentally assign them different call numbers. Later, the CallNo of the other call (the DupCallNo) is appended on to EACH call. , How about creating a unique ID from the two columns:

df %>% rowwise() %>%  
  mutate(Combined = paste0(min(CallNo, DupCallNo, na.rm = TRUE), max(CallNo,DupCallNo, na.rm = TRUE))) 

# A tibble: 4 x 5
# Groups:   Combined [2]
  CallNo DupCallNo Priority Unit    Combined
   <int>     <int> <fct>    <fct>   <chr>   
1    123       255 A        Bravo12 123255  
2    255       123 A        Bravo44 123255  
3    366       476 B        Xray22  366476

Duplicating rows based on a column value in each row

Tag : sql-server , By : ArdentRogue
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further This will support over 7,400 repeats for any individual job (on my system). If you need more, you can use a different system table or a cross join.
DECLARE @d TABLE (Job INT, Quantity INT, Status VARCHAR(12), Repeat INT);

INSERT @d SELECT 1, 100, 'OK'  ,2
UNION ALL SELECT 4, 450, 'OK'  ,3;

  OVER (ORDER BY [object_id]) 
  FROM sys.all_columns 
  ORDER BY [object_id]
WHERE x.rn <= d.Repeat + 1

Splitting (duplicating rows of) an SQL table based on the values in one column

Hope that helps I have a table which is the result of an export and has the columns and values like the following
with cte as (
    select Name, cast(null as int) as AliasStartPosition, cast(0 as int) as AliasEndPosition, Aliases + ' ' as Aliases, cast(null as int) as RankStartPosition, cast(0 as int) as RankEndPosition, Ranks + ' ' as Ranks
    from (
        values ('Ben', 'BenA BenB BenC', '1 5 3'),
               ('Jerry', 'JerryA JerryB', '7 3')
    ) t (Name, Aliases, Ranks)

    union all

    select Name, AliasEndPosition + 1, charindex(' ', Aliases, AliasEndPosition + 1), Aliases, RankEndPosition + 1, charindex(' ', Ranks, RankEndPosition + 1), Ranks
    from cte
    where charindex(' ', Aliases, AliasEndPosition + 1) != 0
select Name, substring(Aliases, AliasStartPosition, AliasEndPosition - AliasStartPosition) as Alias, substring(Ranks, RankStartPosition, RankEndPosition - RankStartPosition) as Rank 
from cte
where AliasStartPosition is not null

like below fixes the issue I would advise against VBA when you can achieve the required results easily with worksheet formulas
Put the following formula into cell D1 and drag down

Python, dataframes : duplicating elements in a column of lists and attributing to them rows in another column

Tag : python , By : BooTeK

this one helps. I think you can use numpy.repeat for repeat values by legths by str.len and flat values of nested lists by chain:
from itertools import chain

df2 = pd.DataFrame({
        "columns_B": np.repeat(df.columns_B.values, df.columns_A.str.len()),
        "columns_A": list(chain.from_iterable(df.columns_A))})

print (df2)
   columns_A        columns_B
0          1      [bob, mary]
1          2      [bob, mary]
2          3      [bob, mary]
3          4      [bob, mary]
4          7  [banana, apple]
5          9  [banana, apple]
df2 = pd.DataFrame(df.columns_A.values.tolist())
        .reset_index(level=1, drop=True)
print (df2)
0    1
0    2
0    3
0    4
1    7
1    9
Name: columns_A, dtype: int32

print (df.drop('columns_A', axis=1).join(df2).reset_index(drop=True))
         columns_B  columns_A
0      [bob, mary]          1
1      [bob, mary]          2
2      [bob, mary]          3
3      [bob, mary]          4
4  [banana, apple]          7
5  [banana, apple]          9

Duplicating rows in R dataframe based on splitting cells in a column

Tag : r , By : Jeskl

With these it helps I have a dataframe as such: , If it is a string column, we can make use separate_rows
df1 %>%
   separate_rows(Col2, convert = TRUE)
#   Col1 Col2
#1    a    2
#2    b    1
#3    b    3
#4    c    4
df1 <- structure(list(Col1 = c("a", "b", "c"), Col2 = c("2", "1, 3", 
"4")), class = "data.frame", row.names = c(NA, -3L))
