Re: qpython to select columns from table

[rocuinneagain]

Some ways:

q("{((),x)#y}", numpy.string_("iq"), numpy.string_("t")) 
q("{value"select ",string[x],"from ",string y}", "iq", "t") 
q("select %s from %s" % ("iq","t")) 
q("{?[y;();0b;{x!x}(),x]}", numpy.string_("iq"), numpy.string_("t"))

 

 

1. Using # https://code.kx.com/q/ref/take/
2. Using value https://code.kx.com/q/ref/value/
3. Python string formatting
