SQL Server : scenario with two tables -


i'm new sql server , learning. ive encountered problem. here scenario of problem.

there 2 tables, 1 addresses , other members.

previously, got 2 columns collecting dates addresses, 1 month , other year.

but decided add 2 columns collect date format (mm/dd/yyyy), instead of inserting data. use old data 2 old date columns month , year. , use identifying id members table , address table g1, g2, g3. identifying id primary key.

i decided manually realized got tons of data , take forever finish if 1 one. idea how this? using microsoft sql server management studio.

so should this.

  • month column = june
  • year column = 2015
  • fulldate column = 06/01/2015

all g1 should

given table like

create table dbo.addresses (     monthcolumn varchar(30),     yearcolumn int )

you add computed column table. since have month name, best bet going to concatenate date string , convert date (note, if integer, use dateadd() or, if you're running sql 2012 or more recent, datefromparts()

alter table dbo.addresses add monthyear convert(date, '01 ' + monthcolumn + ' ' + cast(yearcolumn char(4)), 106) -- 106 mask "dd mon yyyy"

this rely on months being standard datenames. again, if you're able store months ints, life gets easier. is, how i'd approach it.
