-Inyathelo ngenyathelo ➡️ Uzilawula njani iitafile kwindawo egciniweyo kaMariaDB?

• Isinyathelo se1: Ukulawula iitafile kwi-database ye-MariaDB, kufuneka uqale ufikelele kwiseva yedatha.
• Isinyathelo se2: Nje ukuba ungaphakathi kwiseva, khetha isiseko sedatha ethile ofuna ukulawula iitafile usebenzisa umyalelo SEBENZISA igama_lesiseko sedatha;
• Isinyathelo se3: Ukujonga zonke iitafile ngaphakathi kwedatha ekhethiweyo, ungaqhuba umyalelo BONISA IITHEBILE;
• Isinyathelo se4: Ukuba ufuna ukubona ubume betafile ethile, ungasebenzisa umyalelo CHAZA itheyibhile_igama;
• Isinyathelo se5: Ukwenza itafile entsha, sebenzisa umyalelo YENZA itheyibhile_igama (udidi lwekholamu1, uhlobo lwekholamu2, ...);
• Isinyathelo se6: Ukuba ufuna ukucima itafile esele ikhona, ungenza njalo ngomyalelo YILAHLISA ITABILE_igama;
• Isinyathelo se7: Ukuguqula isakhiwo setafile, sebenzisa umyalelo ALTER TABLE table_name…;
• Isinyathelo se8: Ukuba ufuna ukwenza imibuzo okanye uhlengahlengiso kwidatha ekwitafile, ungasebenzisa imiyalelo efana KHETHA ukujonga idatha, BHALA ukongeza iirekhodi ezintsha, UPDATE ukuhlaziya iirekhodi ezikhoyo, kunye SUSA ukucima iirekhodi.
