SP:Recompile Event Class
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
The SP:Recompile event class indicates that a stored procedure, trigger, or user-defined function has been recompiled. Recompilations reported by this event class occur at the statement level.
The preferred way to trace statement-level recompilations is to use the SQL:StmtRecompile event class. The SP:Recompile event class is deprecated. For more information, see SQL:StmtRecompile Event Class.

| DatabaseID | int | ID of the database in which the stored procedure is running. Determine the value for a database by using the DB_ID function. | 3 | Yes |
| DatabaseName | nvarchar | Name of the database in which the stored procedure is running. | 35 | Yes |
| EventClass | int | Type of event = 37. | 27 | No |
| EventSequence | int | The sequence of a given event within the request. | 51 | No |
| EventSubClass | int | Type of event subclass. Indicates the reason for recompilation. 1 = Schema Changed 2 = Statistics Changed 3 = Recompile DNR 4 = Set Option Changed 5 = Temp Table Changed 6 = Remote Rowset Changed 7 = For Browse Perms Changed 8 = Query Notification Environment Changed 9 = MPI View Changed 10 = Cursor Options Changed 11 = With Recompile Option |
21 | Yes |
| GroupID | int | ID of the workload group where the SQL Trace event fires. | 66 | Yes |

| IntegerData2 | int | Ending offset of the statement within the stored procedure or batch that caused recompilation. Ending offset is -1 if the statement is the last statement in its batch. | 55 | Yes |
| IsSystem | int | Indicates whether the event occurred on a system process or a user process. 1 = system, 0 = user. | 60 | Yes |
| LoginName | nvarchar | Name of the login of the user (either SQL Server security login or the Microsoft Windows login credentials in the form of DOMAIN\username). | 11 | Yes |
| LoginSid | image | Security identification number (SID) of the logged-in user. You can find this information in the sys.server_principals catalog view. Each SID is unique for each login in the server. | 41 | Yes |

| ServerName | nvarchar | Name of the instance of SQL Server being traced. | 26 | No |
| SessionLoginName | nvarchar | Login name of the user who originated the session. For example, if you connect to SQL Server using Login1 and execute a statement as Login2, SessionLoginName shows Login1 and LoginName shows Login2. This column displays both SQL Server and Windows logins. | 64 | Yes |
| SPID | int | ID of the session on which the event occurred. | 12 | Yes |
| SqlHandle | varbinary | 64-bit hash based on the text of an ad hoc query or the database and object ID of a SQL object. This value can be passed to sys.dm_exec_sql_text to retrieve the associated SQL text. | 63 | Yes |
| StartTime | datetime | Time at which the event started, if available. | 14 | Yes |
