mysql - Difference between inserto into in each line or just one per table -


i use 2 forms of backup on clients table. use mysqldump , use sqlyog backup.

sqlyog creates insert way:

insert  `tbb111`(`ppu_nome_usu`,`ppu_nome_prg`,`ppu_seq_prg`,`ppu_des_ppu`) values ('rachel','sdmw','0','todas     ;01012014;28022014;00001;;;'); insert  `tbb111`(`ppu_nome_usu`,`ppu_nome_prg`,`ppu_seq_prg`,`ppu_des_ppu`) values ('rachel','sdmw2251','0','01012013;31122014;'); insert  `tbb111`(`ppu_nome_usu`,`ppu_nome_prg`,`ppu_seq_prg`,`ppu_des_ppu`) values ('rachel','sdmw2290','0','todos;01012013;31122014;;;;00000000000;99999999999;;');

and mysqldump creates way:

insert `sdm638` values  ('1','1','201402','1002','computadores e periféricos','0','0','222222','0','733.4800','539.3200','1272.8000','0.0000','0.0000','0.0000','0.0000','0','0','0'),  ('1','1','201402','1008','veículos','0','0','222222','0','0.0000','42900.0000','42900.0000','0.0000','0.0000','0.0000','0.0000','0','0','0'), ('1','1','201402','2001','Água e esgoto','0','0','222222','0','458.6400','458.6400','917.2800','0.0000','0.0000','0.0000','0.0000','0','0','0'), ('1','1','201402','2002','combustível','0','0','222222','0','0.0000','237.6000','237.6000','0.0000','0.0000','0.0000','0.0000','0','0','0'), ('1','1','201402','2004','copa e cozinha','0','0','222222','0','463.2000','181.6998','644.8998','0.0000','0.0000','0.0000','0.0000','0','0','0')

mysqldump better since file lot smaller. tested on client mysqldump got 2.5gb while sqlyog 8gb.

i want know whats difference between them.the mysqldump work without insert in every line? performance same or mysqldump faster since have less code?

thanks guys.

functionally both same, performance point of view latter (mysqldump version) faster since parsing not performed every row rather bunch of rows @ once.
