ERROR_DATABASE_DOES_NOT_EXIST - 1065 (0x429)

The database specified does not exist.

Updated: Feb 21, 2026

Technical Background

The error code ERROR_DATABASE_DOES_NOT_EXIST with the numeric value 1065 and hexadecimal representation 0x429 indicates that a specified database does not exist in the context of a database operation. This error is commonly encountered when working with SQL Server or other database management systems (DBMS) within a Windows environment.

Error Details

  • Error Name: ERROR_DATABASE_DOES_NOT_EXIST
  • Numeric Code: 1065
  • Hex Code: 0x429
  • Short Description: The specified database does not exist.

This error typically arises when a database operation is attempted on a non-existent database. It can occur in various contexts, such as executing SQL queries, performing administrative tasks, or accessing data through application programming interfaces (APIs).

Common Causes

The following are common causes that may lead to this error:

  • Invalid Database Name: The name of the database specified does not match any existing databases.
  • Database Deletion: The database has been deleted before the operation was attempted.
  • Incorrect Connection String: The connection string used in the application or API call is incorrect, leading to an attempt on a non-existent database.

Real-World Context

This error can occur in various scenarios, such as:

  • Executing SQL queries that reference a non-existent database.
  • Attempting to create a new database with a name already used by another resource.
  • Using incorrect connection strings in applications or scripts that interact with the database system.

Is This Error Critical?

The criticality of this error depends on the context. If the application relies heavily on the existence of specific databases, encountering this error can halt operations and require immediate attention to resolve the issue. However, if the application is designed to handle such errors gracefully, it may not be as critical.

How to Diagnose

To diagnose the cause of ERROR_DATABASE_DOES_NOT_EXIST, follow these steps:

  1. Review Operation Context: Ensure that the operation context is correct and matches the intended database name.
  2. Validate Parameters: Verify that all parameters, including the database name, are correctly specified in the application or API call.
  3. Confirm Object Types: Confirm that the object type (database) exists within the system. Use tools like SQL Server Management Studio to check for existing databases.
  4. Verify Input Data: Ensure that the input data is correct and does not contain typos or other errors.
  5. Check Limits or Constraints: Verify that there are no limits or constraints preventing the creation or access of a new database with the specified name.

How to Resolve

To resolve ERROR_DATABASE_DOES_NOT_EXIST, consider the following steps:

  • Correct Parameter Usage: Ensure that all parameters, including the database name, are correctly specified in the application or API call.
  • Adjust Operation Context: If the operation context is incorrect, adjust it to match the intended database.
  • Restore Data: If a database was accidentally deleted, restore the data from backups or other sources.
  • Retry Operation with Valid Inputs: Retry the operation using valid inputs and ensure that all parameters are correctly specified.

Developer Notes

Developers should handle this error by implementing robust validation logic to check for the existence of databases before performing operations. Additionally, providing meaningful error messages can help users understand and resolve issues more effectively.
