All Errors

This error occurs when you try to use a table option or feature that your storage engine (InnoDB, MyISAM, etc.) does not support. Common causes include deprecated options like ROW_FORMAT=FIXED, unsupported INDEX DIRECTORY clauses, or engine-specific features being used with incompatible engines.

This error occurs when running prisma db pull (or prisma introspect) against a database that contains no tables. Prisma cannot generate models from an empty database, so introspection fails.

The NTILE() window function requires a positive integer argument representing the number of buckets. Error 22014 occurs when you pass an invalid argument type or value, such as zero, negative numbers, or non-integer types.

A PostgreSQL sequence has reached its maximum value, preventing new ID generation. This occurs when SERIAL columns exhaust their 4-byte integer range (~2.1 billion). Fix by altering the sequence to BIGINT or using CYCLE mode.

MySQL Error 1317 (ER_QUERY_INTERRUPTED) occurs when a long-running query is forcibly stopped by a KILL command, user interruption (Ctrl+C), or server shutdown. The error typically indicates an external interrupt rather than a query syntax or logic problem. Most cases resolve by allowing queries to complete or implementing proper timeout handling.

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.

PostgreSQL enforces a 63-character maximum length for all identifiers (table names, column names, index names, etc.). When you exceed this limit, PostgreSQL truncates the identifier silently, which can cause duplicate name errors or missing references when your application expects the full name.

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.
