The sqlstate 08001 error code happens when a connection to a SQL Server cannot be established. This can be caused by a number of things, including:

  • the SQL Server being down

  • the server name being incorrect

  • the port number being incorrect

  • a firewall blocking access to the SQL Server

This error can be frustrating to track down, but once the cause is found it can usually be easily fixed.

Other common searches for this error include:

  • sql state 08001 error code
  • sqlstate 08001

1. Ensure that the server is running and that you have the correct hostname and port number in your connection string

  1. Verify that the server is running.
  2. Confirm that you are connecting to the correct server by checking the hostname and port number in your connection string.
  3. If you are still encountering sqlstate 08001, then there may be a problem with the server configuration or the connection string.

2. If you are using SSL, check that your client supports SSL and that you have the correct server certificate

  1. Check if your client supports SSL. If your client does not support SSL, you will need to upgrade to a newer version.
  2. Verify that you have the correct server certificate. The server certificate must be signed by a trusted certificate authority.
  3. Fix the sqlstate error by reinstalling the server certificate.

3. Check that the username and password you are using are correct

  1. In a web browser, open the Oracle Database Connector for Microsoft SQL Server website.
  2. In the Connector for Microsoft SQL Server section, click the Login button.
  3. In the Login form, enter your username and password.
  4. If the username and password are correct, the sqlstate value in the Login form will be 08001. If the value is not 08001, the username and password are not correct, and you will need to change them.

4. Check that the database you are trying to connect to exists

To check that the database you are trying to connect to exists, you can use the following command: SELECT name FROM sys.databases If the database name does not exist, then you will get an error message that states "The database '<database name>' does not exist."

5. Check that your client supports the protocol you are trying to use

Check that the MySQL server is running with the correct version of the MySQL client software. If the MySQL server is running a version of the MySQL client that is not compatible with the protocol you are using, you will get an error message stating that sqlstate 08001 was encountered. Check that the MySQL server has the correct SLLIB connection string configured. If the MySQL server does not have the correct SLLIB connection string configured, you will not be able to connect to the MySQL server using the protocol you are trying to use. Check that the MySQL server is configured to allow the connection you are trying to use. If the MySQL server is not configured to allow the connection you are trying to use, you will not be able to connect to the MySQL server using the protocol you are trying to use.
