All Errors

PostgreSQL error 34000 occurs when you reference a cursor that does not exist, has not been declared, or is not accessible in the current scope. Ensure the cursor is declared before use and accessed within the same transaction where it was created.

When creating stored functions in MySQL with binary logging enabled, you must explicitly declare how the function interacts with data using DETERMINISTIC, NO SQL, or READS SQL DATA. Without one of these declarations, MySQL raises ERROR 1418 to ensure safe replication.

MySQL ERROR 1217 occurs when you try to delete or update a parent table row that is referenced by foreign keys in child tables. This error protects data integrity by preventing orphaned records. Fix it by using CASCADE options, deleting child records first, or restructuring your foreign key constraints.

MySQL error 1216 occurs when you try to insert or update a row in a child table with a foreign key value that does not exist in the parent table. This happens because MySQL enforces referential integrity to prevent orphaned records.

Error 1273 occurs when your MySQL server doesn't recognize a collation used in your database dump, typically because the dump was created with a newer MySQL version than your target server. You can resolve this by replacing the unsupported collation with a compatible one or upgrading MySQL.

ERROR 1296 indicates a MySQL NDB Cluster error occurred during query execution. This generic error wraps underlying cluster-specific errors like cluster failure, connection loss, or transaction abort. Fixes depend on the specific NDB error code and typically involve verifying cluster status, checking connectivity, or adjusting transaction handling.

MySQL throws error 1406 when an INSERT or UPDATE attempts to write a value longer than the column's defined size. Fix by resizing the column, validating input data, or correcting the data type.

MySQL error 1304 (ER_SP_ALREADY_EXISTS) occurs when you try to create a stored procedure, function, trigger, or event with a name that already exists. The fix is to drop the existing routine first or use CREATE OR REPLACE on MySQL 8.0.13+.

ERROR 1297 indicates a temporary issue in MySQL NDB Cluster that may resolve on retry. Common causes include resource exhaustion, node failures, or overloaded REDO logs. Adjusting cluster configuration parameters can prevent recurrence.

MySQL ERROR 1300 occurs when the database encounters character data that doesn't conform to the expected character set encoding, typically during data import or string operations. This error is resolved by aligning character set configurations and ensuring your data uses the correct encoding.

ERROR 1367 occurs when MySQL tries to parse a value that is out of range or invalid for its data type, commonly with DOUBLE/FLOAT overflow or incorrect spatial data. Fix it by validating data types, checking numeric ranges, and using explicit CAST() functions when needed.

MySQL deadlock errors occur when two or more transactions are waiting for each other to release locks. This guide explains why deadlocks happen and provides actionable strategies to prevent, diagnose, and recover from them.

MySQL Error 1451 occurs when you try to delete or update a row in a parent table that has child rows referencing it through a foreign key constraint. This error protects referential integrity but can be resolved by deleting child rows first, using CASCADE rules, or modifying your constraint strategy.

This error occurs after upgrading MySQL versions or when views contain non-ASCII characters. Views lose metadata context during upgrades. Recreating affected views resolves the issue.

MySQL error 1598 occurs when the server cannot write to the binary log, usually due to transaction isolation level conflicts with statement-based logging or filesystem permission issues. Fixing it requires changing the binary log format or transaction isolation level.

MySQL ERROR 1503 occurs when a unique or primary key on a partitioned table doesn't include all columns used in the partition function. Fix it by adding partitioning columns to your unique keys.

This error occurs when you attempt ALTER TABLE partition operations (DROP, REORGANIZE, ANALYZE, etc.) on partitions that do not exist. The most common cause is automated partition maintenance scripts that reference partition names which no longer exist or have been misspelled. Fix by verifying partition names with SHOW CREATE TABLE before running ALTER TABLE commands.

MySQL Error 1614 (XAER_NOTA) occurs when you try to commit, rollback, or prepare an XA distributed transaction that doesn't exist or has already been completed. This commonly happens in replication scenarios or when another connection already committed the transaction.

This error occurs during database backup when PostgreSQL terminates the pg_dump connection prematurely. Common causes include idle transaction timeouts, network interruptions, statement timeouts, and firewall issues. Check server logs and adjust timeout parameters to resolve.

This error occurs when you try to query a materialized view that was created with the WITH NO DATA clause but has never been populated. PostgreSQL requires the underlying query to be executed and the results stored before the view can be queried. Fix it by running REFRESH MATERIALIZED VIEW.
