php - Generating duplicate value mysql query -


edited--

table1 name ownership_profile
table2 name socity_unit

colum in table1: name , unit_id

colum in table2: wings , unit_no

how join in 1 table

if there n rows in table socity_unit same socity_id (as sid in table ownership_profile) see cartesian product of socity_unit x ownership_profile.

thus, every row in ownership_profile each matching row in socity_unit.

now, because have '*' in select statement columns both tables. if first table has many-many columns there illusion rows duplicated, till scroll right, in order see columns second table ...

is case?
