All Errors

MySQL Error 1050 occurs when attempting to CREATE a table that already exists in the database. Fix it using IF NOT EXISTS clause or by checking/dropping the existing table first.

ERROR 1054 occurs when MySQL cannot find a column you referenced in your query. This is usually caused by a typo, missing quotes around string values, or referencing a column that does not exist in the table.

PostgreSQL error 25006 occurs when your session attempts to write to the database while in read-only mode. Read-only mode can be enabled at the database, session, or transaction level, preventing any INSERT, UPDATE, DELETE, or DDL operations. Disable read-only mode or connect to the primary server to resolve this.

ERROR 1055 occurs when a SELECT statement includes non-aggregated columns not in the GROUP BY clause while ONLY_FULL_GROUP_BY mode is enabled. Fix by adding missing columns to GROUP BY, using aggregate functions, or applying ANY_VALUE() to accept arbitrary values.

This error occurs when a column name referenced in your query exists in multiple joined tables, and MySQL cannot determine which table the column comes from. Qualify column names with table or alias prefixes to resolve the ambiguity.

This error occurs when you try to create an index or key on a column that doesn't exist in your MySQL table. It's typically caused by typos in column names, case sensitivity issues, or referencing a non-existent column in your ALTER TABLE or CREATE TABLE statement.

PostgreSQL raises this error when you attempt a write operation (INSERT, UPDATE, DELETE, CREATE, etc.) on a standby/replica server that is in recovery mode. Only the primary/master server accepts write transactions. Route write operations to the primary server to resolve this.

This error occurs when a GROUP BY query selects columns that are not aggregated or included in the GROUP BY clause. Add missing columns to GROUP BY or wrap them in aggregate functions like MAX(), MIN(), or ANY_VALUE().

MySQL ERROR 1036 occurs when the database cannot write to a table due to permission issues or read-only settings. This usually happens after copying database files, incorrect ownership, or enabling global read-only mode. Most commonly resolved by fixing file permissions.

SQLITE_MISUSE (error code 21) indicates the SQLite library is being used incorrectly, typically from using finalized statements, accessing connections from multiple threads, or calling API functions in the wrong order.

This Prisma Migrate error occurs when a database migration fails during execution and is automatically rolled back. The migration remains in a failed state and must be resolved before new migrations can be applied.

P1017 occurs when your database server unexpectedly closes the connection to Prisma. This can happen during migrations, query execution, or seed operations due to network issues, connection limits, or database server problems.

PostgreSQL terminates idle transactions to prevent locks and table bloat. Configure idle_in_transaction_session_timeout to set a maximum idle period, or disable it (0ms) for maintenance operations.

This warning appears when a PostgreSQL procedure returns multiple dynamic result sets using refcursors. It's informational, not an error, indicating that multiple cursors were opened and returned.

This PostgreSQL error occurs when CREATE TABLE or ALTER TABLE statements contain conflicting clauses, syntax errors, or violate table design rules like defining multiple primary keys or mixing incompatible table types.

This error occurs when PostgreSQL receives a value that doesn't match the UUID format (FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF). Common causes include empty strings, malformed UUIDs, or passing non-UUID data types to UUID columns.

A transaction rollback occurs when PostgreSQL automatically cancels all changes in a transaction block due to an error or constraint violation. Understanding the causes and recovery methods helps prevent data inconsistency and application crashes.

This error occurs when attempting to send a Firebase Cloud Messaging notification without properly specifying the recipient token, topic, or condition. The message cannot be delivered because FCM doesn't know where to send it.

This error occurs during Prisma introspection when your database has cross-schema foreign key references or multiple schemas that aren't properly configured in your Prisma schema file.

This error occurs when an insert, update, or delete operation violates a foreign key relationship between tables. Foreign key constraints must be explicitly enabled in SQLite and violations happen when referenced data is missing or incorrectly modified.
