i'm using select below. select a.bada, b.boom, ' ' '---', * ... there's bunch of joins along way , have data need but rows repeated respect bada , boom . not exact duplicates because values brought in star differ. however, not relevant case. the solution i'm applying listing interesting columns explicitly wonder of there's smooth way eliminate rows have bada , boom repeated (keeping 1 occurrence of such row). most databases support ansi standard window , ranking functions. such, can choose particular or arbitrary rows in set rows same values in columns: select t.* ( select t.bada, t.boom, row_number() on (partition bada, boom order bada) seqnum, t.*, table t) t seqnum = 1; this works first adding sequence number of each row over partition of original table. row number consecutive respect selected columns. once that's done, it's possible pick value of consecutive counter, e.g. 1. s...

essentially opposite of create table workspace variables . i.e. table containing var1, var2, ... , assign var1, var2 base environment, or if called within function, assign these variables calling environment. for example: load patients patients = table(age,gender,height,weight,smoker,... 'rownames',lastname); patients has 5 variables, assign them workspace. e.g. age = patients.age , gender = patients.gender ... there way without manually typing everything? the example given in documentation think should you're looking for. completeness, i'll create table can verified: create table: load patients patients = table(age,gender,height,weight,smoker,... 'rownames',lastname); extract data table , assign variable a : a = patients{1:5,{'height','weight'}}; a 5x2 array of height , weight of patients 1-5, can seen from: whos a; hope helps!
