i need to create a script which update the mysql records
i have this table
ID CODE 1000 abcd 1001 abcd 1002 abcd 1003 abcd 1004 abcd ....... 1049 abcd 1050 qwer 1051 qwer 1052 qwer 1053 qwer ....... 1098 qwer 1099 qwer 1100 38xs ...... 17037 djaso 17038 djaso
i need to update only the IDs. There are like 25.000 rows in this table, the IDs are not all sequential (1,2,3,6...49,80,81...129,283,284...24800,24801...24810,25000) then the ID's will start from last ID+1 (25001)
each CODE is present in this table 50 times and the IDs corresponding to each code are sequential
How can i do that?
Thank you!
