SQL Server Error Msg 8622 – Query processor could not produce a query plan because of the hints defined in this query

In this blog post, let’s learn about the error message “8622 – Query processor could not produce a query plan because of the hints defined in this query. Resubmit the query without specifying any hints and without using SET FORCEPLAN.” in Microsoft SQL Server, the reason why it appears and the solution to fix it.

SQL Server Error Message

8622 – Query processor could not produce a query plan because of the hints defined in this query. Resubmit the query without specifying any hints and without using SET FORCEPLAN.

Reason for the Error

The SQL Server Error Msg 8622 occurs when a query submitted to the SQL Server query optimizer contains hints or the SET FORCEPLAN option. These hints and options override the query optimizer’s usual processes for generating a query plan, which can cause the optimizer to be unable to produce a valid plan for the query. Specifically, the error message states “Query processor could not produce a query plan because of the hints defined in this query. Resubmit the query without specifying any hints and without using SET FORCEPLAN.”

Here are some examples of what can cause this error message to appear:

  1. Using the FORCESEEK hint to force the query optimizer to use an index seek operation.
  2. Using the FORCESCAN hint to force the query optimizer to use a table scan operation.
  3. Using the SET FORCEPLAN option to force the query optimizer to use a specific plan for the query.

Solution

To fix the SQL Server Error Msg 8622, the query needs to be resubmitted without any hints or the SET FORCEPLAN option. This will allow the query optimizer to use its usual processes to generate a query plan for the query.

Here is an example of how to fix the SQL Server Error Msg 8622:

Let’s say we have a query that includes the hint FORCESEEK to force the query optimizer to use an index seek operation. The query looks like this:

SELECT * FROM Customers WITH (FORCESEEK) WHERE CustomerID = 1

When we execute this query, we receive the error message:

“Msg 8622, Level 16, State 1, Line 1 Query processor could not produce a query plan because of the hints defined in this query. Resubmit the query without specifying any hints and without using SET FORCEPLAN.”

To fix the error, we can remove the FORCESEEK hint from the query and resubmit it. The corrected query looks like this:

When we execute this query without any hints, the query optimizer can generate a query plan based on its usual processes, and the query should execute successfully.
