sql - Using cast on a view in a Derby database that has multiple columns -


this question quick one. know select cast(somecolumn othertype) myview, myview view in derby database, combinable other statements in select statement? in other words, select columna, cast(columnb othertype), someothercolumns myview, or have cast entire query? //i have been looking online might help, no examples of this. have tried on w3schools.com, complaining database read-only (somehow, cast() changing database!). otherwise, have found no working examples has done asking here.

i have found answer question: yes, can have said above in derby. here example: http://www.ibm.com/developerworks/library/os-ad-trifecta6/ //although still couldn't use methods on database on w3schools.com!

you not have cast entire freaking table; cast 1 column @ time! heck, in derby, double(23), , return 23.000000!
