Removing duplicate records in MariaDB can be achieved using several different methods. Here are a few simple steps using one such method:
1. Create a new table with the same structure, but no indexes or keys:
\`\`\` CREATE TABLE sort_table LIKE original_table; \`\`\`1. Insert rows from the original table into this new table, but group them to avoid duplicates:
\`\`\` INSERT INTO sort\_table SELECT \* FROM original\_table GROUP BY column1, column2; \`\`\` Replace `column1, column2` with the columns by which you want to group. This operation will select only distinct records.1. Drop the original table:
\`\`\` DROP TABLE original\_table; \`\`\`1. Rename the new table to the name of the original table:
\`\`\` RENAME TABLE sort_table TO original_table; \`\`\`1. If the original table had indexes or keys, don’t forget to recreate them on the renamed table.
Warning: Always backup your data before performing such operations, as they can lead to data loss if not executed correctly!
