User Action

  1. View the statement causing the recompilation by running the following query. Replace the sql_handle, starting_offset, ending_offset, and plan_handle placeholders with the values specified in the error message. Note that the database_name and object_name columns will be NULL for ad hoc and prepared Transact-SQL statements.

    SELECT DB_NAME(st.dbid) AS database_name

    , OBJECT_NAME(st.objectid) AS object_name

    , st.text

    FROM sys.dm_exec_query_stats AS qs

    CROSS APPLY sys.dm_exec_sql_text (sql_handle) AS st

    WHERE qs.statement_start_offset = starting_offset

    AND qs.statement_end_offset = ending_offset

    AND qs.plan_handle = plan_handle;

  2. Based on the reason code description, modify the statement, batch, or procedure to avoid recompilations. For example, a stored procedure may contain one or more SET statements. These statements should be removed from the procedure. For additional examples of recompilation causes and resolutions, see Batch Compilation, Recompilation, and Plan Caching Issues in SQL Server 2005.

  3. If the problem persists, contact Microsoft Customer Support Services.
