mysql - Is it possible to create group_id using repeating text information from another column -


let's have table like

id      |   group_id    |   text    | -------------------------------------- 1       |                   |   nba -------------------------------------- 2       |                   |   nhl -------------------------------------- 3       |                   |   nba -------------------------------------- 4       |                   |   nhl -------------------------------------- 5       |                   |   nhl --------------------------------------

is possible create group_id mysql function or query or :) using fact of repeating (duplicate) text in column text ? have table that

id      |   group_id    |   text    | -------------------------------------- 1       |       10      |   nba -------------------------------------- 2       |       11      |   nhl -------------------------------------- 3       |       10      |   nba -------------------------------------- 4       |       11      |   nhl -------------------------------------- 5       |       11      |   nhl --------------------------------------

you try use hex function:

select id, hex(text) group_id, text tbl

if want decimal value, can conver hex:

select id, conv(hex(text), 16, 10) group_id, text tbl

result:

id  group_id    text 1   5128769 nba 2   5128769 nba 3   5130316 nhl 4   5130312 nhh 5   5130316 nhl 8   4342081 baa 9   4342081 baa

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
