rondog Posted June 12, 2010 Share Posted June 12, 2010 I have a database with like 3000 entries that all have the full state name like "California"...I need to change all these to the abbreviated version like "CA". Can someone help me come up with a script to just run once and have it update all the entries? I already have an array of state info with both full name and abbreviation: $states_arr = array('AL'=>"Alabama",'AK'=>"Alaska",'AZ'=>"Arizona",'AR'=>"Arkansas",'CA'=>"California",'CO'=>"Colorado",'CT'=>"Connecticut",'DE'=>"Delaware",'FL'=>"Florida",'GA'=>"Georgia",'HI'=>"Hawaii",'ID'=>"Idaho",'IL'=>"Illinois", 'IN'=>"Indiana", 'IA'=>"Iowa", 'KS'=>"Kansas",'KY'=>"Kentucky",'LA'=>"Louisiana",'ME'=>"Maine",'MD'=>"Maryland", 'MA'=>"Massachusetts",'MI'=>"Michigan",'MN'=>"Minnesota",'MS'=>"Mississippi",'MO'=>"Missouri",'MT'=>"Montana",'NE'=>"Nebraska",'NV'=>"Nevada",'NH'=>"New Hampshire",'NJ'=>"New Jersey",'NM'=>"New Mexico",'NY'=>"New York",'NC'=>"North Carolina",'ND'=>"North Dakota",'OH'=>"Ohio",'OK'=>"Oklahoma", 'OR'=>"Oregon",'PA'=>"Pennsylvania",'RI'=>"Rhode Island",'SC'=>"South Carolina",'SD'=>"South Dakota",'TN'=>"Tennessee",'TX'=>"Texas",'UT'=>"Utah",'VT'=>"Vermont",'VA'=>"Virginia",'WA'=>"Washington",'DC'=>"Washington D.C.",'WV'=>"West Virginia",'WI'=>"Wisconsin",'WY'=>"Wyoming"); Quote Link to comment Share on other sites More sharing options...
kenrbnsn Posted June 12, 2010 Share Posted June 12, 2010 Make another array with the state names as the keys and the abbreviations as the values: <?php $states_abbr = array(); foreach ($states_arr as $abbr => $state) { $states_abbr[$state] = $abbr } ?> The simply retrieve each record and use the $states_abbr array to get the correct abbreviation and update the record.

ignace Posted June 12, 2010 Share Posted June 12, 2010 Update the table: $case = ''; foreach ($states_arr as $country_code => $country_name) { $case .= "WHEN '$country_name' THEN '$country_code' "; } $query = "UPDATE table SET country_code = (CASE country_name $case END)"; echo $query;//check if query was properly constructed Or use ken's solution to map states to their abbreviations at run-time.

kenrbnsn Posted June 12, 2010 Share Posted June 12, 2010 I definitely have to learn about the CASE in MySQL... Thanks. Ken Quote Link to comment Share on other sites More sharing options...

jcbones Posted June 13, 2010 Share Posted June 13, 2010 I would have suggested. $search_term = 'California'; $abbr = array_keys($states_arr,$search_term); echo $abbr[0]; This would run at runtime, I don't know if I would change all of those columns. If I wanted to input them into the Base, I would add a column. Quote Link to comment Share on other sites More sharing options...
