Hi Guys, The quickest one is to write a query that does that or else write a script that will remove your duplicates. Lets check on how we can achieve this using a query and introducing a UNIQUE index on our solumn Say for example I have a table as shown below And I have data such as the one shown below (lat, lng columns removed) id street_name city_id state_id display_name last_modified_on 1434419 Moorefields Rd 224 2 Moorefields Road, Sydney NSW 2209, Australia 1359946138 1434420 Kingsgrove Rd 701 2 Kingsgrove Road, Clemton Park NSW 2206, Australia 1359946139 1434421 Dewar St 13260 8 Dewar Street, Armadale WA 6112, Australia 1359946140 1434423 Dewar St 13151 8 Dewar Street, Morley WA 6062, Australia 1359946142 1434424 Dewar St 9793 4 Dewar Street, Point Arkwright QLD 4573, Australia 1359946143 1434425 Dewar St 13929 8 Dewar Street, Lake Grace WA 6353, Australia 1359946144 1434426 Dewar St 681 2 Dewar Street, Campsie NSW 2194, Australia 1359946145 1434428 Dewar St 10990 4 Dewar Street, Mission Beach QLD 4852, Australia 1359946147 1434429 Anglo Rd 342 2 Anglo Road, Greenwich NSW 2065, Australia 1359946148 1434430 Anglo Rd 681 2 Anglo Road, Campsie NSW 2194, Australia 1359946150 1434445 Anglo Rd 681 2 Anglo Road, Campsie NSW 2194, Australia 1359946150 1434450 Anglo Rd 681 2 Anglo Road, Campsie NSW 2194, Australia 1359946150 As you can see that entry Anglo Road, Campsie NSW 2194, Australia is repeated three times and data other than my row ID is pretty much the same so how do I get rid of duplicates Here is a quick query to do that   mySQL query [crayon-6483388ea9884569988486/] This will remove my duplicates rows. Most important part of above query is using ALTER with IGNORE More details can be found here But to wrap things up this here is a quick explanation from above … [Read more...]
