All Errors

The "Must be owner of table" error occurs when a user attempts to alter, drop, or modify a table they do not own. Only the table owner (or superuser) can perform schema modifications on a table in PostgreSQL.

PostgreSQL error 42501 "insufficient privilege" occurs when a user attempts an operation without the necessary permissions on a database object. This role-based access control error requires granting appropriate privileges via GRANT statements.

MySQL Error 2026 occurs when SSL/TLS handshake fails between client and server, typically due to protocol version mismatches, missing or expired certificates, or configuration mismatches. Fix it by verifying SSL is enabled on both sides, updating client libraries, and ensuring certificate files are accessible.

The MySQL client runs out of memory while processing a query result set or allocating memory for operations. This error occurs when the result set is too large for available client memory, the client application is 32-bit, or when memory is poorly configured.

The reserved name error occurs when using PostgreSQL reserved keywords as column or table names without proper quoting. PostgreSQL distinguishes between reserved and non-reserved keywords, and reserved words cannot be used as identifiers unless wrapped in double quotes.

MySQL Error 1030 "Got an error reading communication packets" occurs when the server cannot properly read data packets from a client connection. Common causes include network interruptions, timeout settings, oversized packets, improperly closed connections, and proxy/load balancer issues. Fixing requires adjusting timeout values, increasing max_allowed_packet, and ensuring proper connection handling.

MySQL Error 2006 (HY000) occurs when the connection between your client and MySQL server is lost. Common causes include connection timeouts, large packets, firewall issues, server crashes, and killed connections. Fixing requires adjusting wait_timeout, increasing max_allowed_packet, checking network connectivity, and verifying server health.

This error occurs when PostgreSQL encounters an identifier (table name, column name, function name, etc.) that violates naming rules. Identifiers must start with a letter or underscore, contain only alphanumeric characters and underscores, and be 63 characters or fewer. Reserved keywords used as identifiers without proper quoting also trigger this error.

A check constraint violation occurs when you attempt to insert or update data that doesn't meet the boolean condition defined by a CHECK constraint on a table column. This is PostgreSQL's way of enforcing data integrity rules at the database level.

MySQL error 1305 occurs when you try to call a stored function that doesn't exist in the database. This commonly happens due to spaces between the function name and parentheses, incorrect database context, misspelled function names, or calling a stored procedure as a function.

MySQL Error 1364 occurs when inserting or updating a row with a NOT NULL column that has no default value and you fail to provide an explicit value. This error is triggered by MySQL's STRICT_TRANS_TABLES mode. Solutions include providing explicit values, adding defaults to columns, using AUTO_INCREMENT, or altering table definitions.

The "Numeric value out of range" error occurs when a numeric value exceeds the valid range for its data type. This typically happens when inserting large numbers into INTEGER/BIGINT columns or when NUMERIC/DECIMAL precision is insufficient.

Window functions in MySQL cannot have ORDER BY redefined when the named window already contains an ORDER BY clause. Remove the redundant ORDER BY from the OVER clause to resolve this error.

MySQL Error 2005 occurs when the MySQL client cannot resolve or connect to the specified hostname. Common causes include typos in the hostname, incorrect hostname format (including protocol), DNS resolution failures, network connectivity issues, or the port being included in the hostname. Fixing requires verifying the hostname spelling, using correct connection syntax, and testing network connectivity.

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.
