sql - Postgresql regular expression matching function: regexp_matches -

-

given string want extract expression matching regexp (e.g. email) array. here actual code, using postgresql 9.4 :

select regexp_matches('user1@gml.com lorem ipsum user2@yho.com',                       '([a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4})',                       'g')

the output 2 records:

 regexp_matches    -----------------  {user1@gml.com}  {user2@yho.com}  (2 rows)

what want have matches in 1 array e.g.:

regexp_matches   ----------------- {user1@gml.com, user2@yho.com} (1 row)

how achieve that?

you can unnest each result array, array_agg lot of them together.

it's bit ugly:

select array_agg(x) (     select unnest(        regexp_matches('user1@gml.com lorem ipsum user2@yho.com',                       '([a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4})',                       'g')     ) ) a(x);

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
