All Errors

This MySQL error occurs when you define an AUTO_INCREMENT column without a key constraint, or attempt to create multiple AUTO_INCREMENT columns. Fix it by adding PRIMARY KEY to your AUTO_INCREMENT column or ensuring only one auto column exists per table.

This error occurs when you attempt to create a database with CREATE DATABASE but a database with that name already exists. The fix is to use CREATE DATABASE IF NOT EXISTS to make the statement idempotent, or drop the existing database first if you want to start fresh.

MySQL Error 1073 occurs when trying to use a BLOB column as a key or index without specifying a prefix length. This happens because BLOB columns store variable-length data that MySQL cannot fully index, requiring either a table engine change, prefix length specification, or column type modification.

MySQL error 1022 occurs when you try to insert or update a row with a value that already exists in a column with a UNIQUE or PRIMARY KEY constraint. This guide shows how to identify duplicates, fix constraint conflicts, and safely update your data.

This error occurs when attempting to restore or migrate a key using Redis commands like RESTORE or MIGRATE, but a key with that name already exists at the destination. It prevents overwriting the existing key unless the REPLACE option is specified.

MySQL Error 1035 appears when the MyISAM storage engine detects a corrupted or outdated .MYI key file. Quick repair using REPAIR TABLE or myisamchk restores access to your table and prevents data integrity issues.

This error occurs when a query references a table that was not included in a preceding LOCK TABLES statement. Fix it by adding all required tables to your lock statement or by using UNLOCK TABLES to release locks and switch to transactions.

This error occurs when you try to create a table, index, or constraint with a name that already exists in the table. Common causes include running migrations twice or conflicting auto-generated index names. Fix it by checking existing indexes and either dropping the duplicate or using IF NOT EXISTS syntax in MySQL 8.0+.

MySQL Error 1074 occurs when a VARCHAR or CHAR column exceeds the maximum byte limit of 65,535 bytes. The actual character limit depends on your character set (UTF-8, GBK, Latin1), and can be reduced when using multi-byte encoding.

This MySQL error occurs when an INSERT statement tries to insert data into a table, but the number of columns specified doesn't match the number of values provided. The error is a validation check that prevents inserting incomplete or misaligned data. The mismatch typically happens when you don't explicitly list column names and provide the wrong number of values, or when you list columns but provide a different count of values.

ERROR 1010 occurs when MySQL cannot remove a database directory due to extra files or permission issues. The directory contains files that MySQL doesn't recognize or can't delete, preventing the DROP DATABASE command from completing successfully.

ERROR 1008 occurs when attempting to drop a database that doesn't exist on the MySQL server. The quickest fix is to use the IF EXISTS clause to prevent the error, or verify the database name and ensure it exists before dropping.

Error 1076 (ER_READY) is not actually an error but an informational message indicating that your MySQL server has successfully started and is ready to accept client connections. No action is required unless the message appears repeatedly, which could indicate server crashes.

This warning appears when dpkg tries to remove a package it doesn't recognize as installed. Usually harmless, but indicates a package state mismatch between apt and dpkg.

MySQL ERROR 1024 (ER_ERROR_ON_READ) occurs when MySQL cannot read a database file due to permissions, corruption, or disk issues. Fixes involve checking permissions, disk space, file integrity, and restarting the MySQL server.

MySQL Error 1045 occurs when connection credentials are incorrect, the user lacks privileges from the specified host, or authentication settings are misconfigured. Fix it by verifying credentials, checking user permissions, and adjusting authentication plugins on MySQL 8.0+.

MySQL Error 1104 occurs when a SELECT query would examine more rows than the max_join_size limit allows. This typically happens with unindexed joins on large tables. Fix it by optimizing your query with proper indexes, adding WHERE clauses, or temporarily enabling SQL_BIG_SELECTS.

ERROR 1032 occurs when MySQL cannot locate a record during DELETE or UPDATE operations, commonly due to replication drift, table corruption, or incorrect WHERE clauses. This guide shows how to identify the root cause and resync your databases.

The P2018 error occurs when Prisma cannot find the records you're trying to connect in a relation operation. This typically happens when you're using connect, connectOrCreate, or disconnect operations with IDs that don't exist, or when dealing with explicit many-to-many relationships.

ERROR 1005 occurs when MySQL cannot create a table, usually due to foreign key constraint issues. Most commonly, this happens when data types don't match, storage engines are incompatible, or referenced tables don't exist. Fix by ensuring matching column types, using InnoDB for both tables, and verifying all referenced objects exist.
