All Errors

MySQL ERROR 1566 occurs when you attempt to modify binary log format settings while temporary tables are open in the session. This replication safety mechanism prevents data inconsistency between primary and replica servers. Fixing requires closing all temporary tables before changing binlog_format settings.

Replication slots become inactive when the connected replica or client disconnects, causing PostgreSQL to retain WAL files indefinitely. This leads to disk space bloat and prevents autovacuum from cleaning dead tuples. Reconnect the subscriber or safely drop unused slots.

This error occurs when the database provider in your Prisma schema differs from the provider recorded in migration_lock.toml. It prevents applying migrations created for a different database system.

Prisma detects that your schema changes would cause data loss. This occurs when adding required fields without defaults, dropping columns, or changing field constraints. Resolve it by modifying your schema, using the --accept-data-loss flag carefully, or customizing migrations.

MySQL Error 1212 occurs when attempting to create a MERGE table with constituent tables located in different databases. MERGE tables are a special storage engine (MRG_MyISAM) that combines multiple identical MyISAM tables into a single virtual table. This error indicates that all underlying tables must reside in the same database for the MERGE table to function correctly.

MySQL received a network packet larger than the max_allowed_packet limit. Increase max_allowed_packet in your MySQL configuration to handle larger queries, database imports, or BLOB data uploads.

MySQL error 2007 (CR_VERSION_ERROR) occurs when the client and server use incompatible protocol versions or when connecting to the wrong port. This commonly happens with Docker port mapping errors or version mismatches between old clients and new servers. Fixing it requires checking port configuration and ensuring client/server version compatibility.

MySQL Error 2013 occurs when the connection between your client and database server is unexpectedly terminated while executing a query. This happens due to timeouts, oversized packets, network instability, or server overload. Solutions include increasing timeout values, optimizing slow queries, raising max_allowed_packet, and ensuring stable network connectivity.

MySQL Error 2002 occurs when the client cannot locate or access the Unix socket file used for local MySQL connections. This typically means the MySQL server is not running, the socket path is incorrect, or there are permission issues. Fix it by checking if the server is running, verifying socket file location and permissions, or using TCP/IP instead of socket connections.

MySQL Error 2004 (CR_IPSOCK_ERROR) occurs when the MySQL client cannot create a TCP/IP socket to connect to the server. This is a client-side error caused by resource exhaustion, system limits, permission issues, or network configuration problems. Fixing requires checking file descriptor limits, system resources, and network settings.

The MySQL client cannot establish a connection to the MySQL server at the specified host. This commonly occurs when the server isn't running, firewall rules block the connection, the bind address is misconfigured, or network connectivity is unavailable.

ERROR 1205 occurs when a transaction waits longer than the innodb_lock_wait_timeout limit (default 50 seconds) to acquire a row lock held by another transaction. This typically happens when transactions are slow, lock contention is high, or connections are idle but uncommitted. Fix by optimizing query performance, reducing transaction duration, increasing the timeout threshold, or killing blocking connections.

MySQL Error 1034 (ER_NOT_KEYFILE) indicates that MySQL cannot read the index (key) file for a table, usually due to corruption caused by disk issues, crash interruption, or filesystem problems. Common causes include insufficient disk space, permission errors, and MyISAM table corruption. Fixing requires checking disk space, repairing tables, and verifying filesystem health.

The "no data found" error occurs when a PL/pgSQL SELECT INTO STRICT statement returns zero rows. Handle it using the FOUND variable or catch the NO_DATA_FOUND exception in your stored procedures.

This error occurs when a trigger updates the same table that triggered it, causing infinite recursion until PostgreSQL hits the stack depth limit. Fix it by adding conditional checks or using pg_trigger_depth() to prevent the trigger from re-executing on its own updates.

This error occurs when you attempt to add a replica to a DynamoDB global table in a region where one already exists. Each global table can only have one replica per AWS region. Resolve this by checking existing replicas or removing orphaned ones before recreating.

PostgreSQL crash shutdown (57P02) occurs when the server crashes and terminates all client connections during recovery. The server automatically restarts and replays the write-ahead log (WAL) to restore data integrity.

A socket timeout occurs when redis-py cannot read a response from Redis within the configured time limit. This typically happens with slow networks, blocking commands, or idle connections closed by the server.

This error occurs when attempting to modify a PostgreSQL configuration parameter that cannot be changed at runtime. Most parameters require server restart or configuration file changes rather than SET commands.

The auth/missing-phone-number error occurs when calling Firebase phone authentication methods without providing a valid phone number. This is thrown when the phone number parameter is missing or not passed to signInWithPhoneNumber or verifyPhoneNumber.
