I have a table in that table there is a column called eq1.sources in that column, entries are like mentioned below. Now I would like to extract the string from the left side to till card slot number only.
Example:
fdn:realm:pam:network:55.150.40.841:shelf-1:cardSlot-1:card:daughterCardSlot-1:daughterCard
for this entry I need only
fdn:realm:pam:network:55.150.40.841:shelf-1:cardSlot-1
similarly
fdn:realm:sam:network:35.250.40.834:shelf-1:cardSlot-1:card
for this entry I need
fdn:realm:sam:network:35.250.40.834:shelf-1:cardSlot-1
I have tried substring(eq1.sources,0,position (':card:daughter' in eq1.sources)). this is working only for row numbers 1,2,4,5,6,7,9,10 but row number 3,8,11 not working as the entries not continued with ':card:daughter'.
The column name for the below entries is eq1.sources.
1.fdn:realm:pam:network:55.150.40.841:shelf-1:cardSlot-1:card:daughterCardSlot-1:daughterCard

First split the string into an array with : as a delimiter (this is the t subquery) and then pick the first 7 array elements and join them again into a string with : delimiter.
select array_to_string(arr[1:7], ':') as sources
from
(
select string_to_array(sources, ':') as arr
from the_table
) as t;
See demo.
I tried
myTable.MyField{:}='AAA'
myTable.MyField(:)='AAA'
myTable.MyField{:}={'AAA'}
myTable.MyField{:}=deal('AAA')
but all failed.
Is there any way?
MATLAB requires:
To assign to or create a variable in a table, the number of rows must match the height of the table.
So it would be:
myTable.MyField = repmat('AAA', length(myTable.MyField), 1);
or if you know the column number of MyField, you can do:
myTable(:,colnum) = {'AAA'}; %where colnum is the column number
or otherwise if you don't know the column number, you can directly use the column name as well:
myTable(:,'MyField') = {'AAA'};
Similar to Excel, I need to find out how to filter out rows of a table that do not contain a certain string.
For example, I need only rows that contain the letters "MX". Within the sheet, there are rows with strings like ZMX01, MX002, and US001. I would want the first two rows.
This seems like a simple question, so I am surprised I couldn't find any help for this!
It is similar to the question Filter on words in Matlab tables (as in Excel)
You may not find a lot of information on tables in MATLAB, as they were introduced with version R2013a, which is not that long ago. So, about your question: Let's first create a sample table:
% Create a sample table
col1 = {'ZMX01'; 'MX002'; 'US001'};
col2 = {5;7;3};
T = table(col1, col2);
T =
col1 col2
_______ ____
'ZMX01' [5]
'MX002' [7]
'US001' [3]
Now, MATLAB provides the rowfun function to apply any function to each row in a table. By default, the function you call has to be able to work on all columns of the table.
To only apply rowfun to one column, you can use the 'InputVariables' parameter, which lets you specify either the number of the column (e.g. 2 for the second column) or the name of the column (e.g. 'myColumnName').
Then, you can set 'OutputFormat' to 'uniform' to get an array and not a new table as output.
In your case, you'll want to use strfind on the column 'col1'. The return value of strfind is either an empty array (if 'MX' wasn't found), or an array of all indices where 'MX' was found.
% Apply rowfun
idx = rowfun(#(x)strfind(x,'MX'), T, 'InputVariables', 'col1', 'OutputFormat', 'uniform');
The output of this will be
idx =
[2]
[1]
[]
i.e. a 3-by-1 cell array, which is empty for 'US001' and contains a positive value for both other inputs. To create a subset of the table with this data, we can do the following:
% Create logical array, which is true for all rows to keep.
idx = ~cellfun(#isempty, idx);
% Save these rows and all columns of the table into a new table
R = T(idx,:);
And finally, we have our resulting table R:
R =
col1 col2
_______ ____
'ZMX01' [5]
'MX002' [7]
I have two columns of dates and I want to run a query that returns TRUE if there is a date in existence in the first column and in existence in the second column.
I know how to do it when I'm looking for a match (if the data entry in column A is the SAME as the entry in column B), but I don't know know how to find if data entry in column A and B are in existence.
Does anyone know how to do this? Thanks!
If data in a column is present, it IS NOT NULL. You can query for that on both columns, with and AND clause to get your result:
SELECT (date1 IS NOT NULL AND date2 IS NOT NULL) AS both_dates
FROM mytable;
So, rephrasing:
For any two entries in table x with date columns a and b, is there some pair of rows x1 and x2 where x1.a = x2.b?
If that's what you're trying to do, you want a self-join, e.g, presuming the presence of a single key column named id:
SELECT x1.id, x2.id, x1.a AS x1_a_x2_b
FROM mytable x1
INNER JOIN mytable x2 ON (x1.a = x2.b);
I have two seperate sheets
Sheet 1
Column A is a list of Drugs
Column B is the identity code for that drug
Column C is to be the equation
Sheet 2
Column A is the Idendity code as in B above
Column B is the funding value for this medicine.
I would like to create a function that matched Sheet1 B with Sheet2 A and then prints the value in Sheet2 B on sheet1 C.
