SQL Append table queries -
i have 2 tables, table1 2 rows of data row11 , row12 , table2 3 rows of data sat row21, row22, row23
can provide me sql create query returns
row11 row12 row21 row22 row23 note: dont want create new table return data.
use union all, based on example data:
select * table1 union select * table2 union removes duplicates - if both tables each had row values "rowx, 1", query return 1 row, not two. makes union slower union all, because union all not remove duplicates. know data, , use appropriately.
