Blockingīecause SPIDs define an atomic operation and are independent, they can often compete with each other depending on their Transaction Isolation levels, the objects they are accessing, and the operation they are performing. This comes in useful when sharing data between stored procedures. This is how separate stored procedures can share the temp table because any temp table created in a spid’s session is global to the session. Temp tables that are created within a SPID are accessible from any proceeding execution in that SPID. For more on isolation levels, view this Temp Table sharing When set within a connection, all proceeding executions maintain the same transaction isolation. SPIDs can have their own transaction isolation levels defined globally. In order to view the connections settings execute the SQL Statement shown above. If two different SPIDs come in with different connection settings, then they will not use the same execution plan defined for a SQL statement. This is important because execution plans that are generated for queries are dependent on the connection settings. Connection settings can be defined by the connection string or the default values for the SQL Server instance, so if two SPIDs come in through the same connection string, then they will also have the same connection settings. To find the SPID for your current execution window run this.Įach SPID can have it’s own connection settings. In order to view all the connections in SQL Server execute the following query.įrom here we see a session_id shown in the left hand column. The term SPID is synonymous with Connection, or Session. This connection has a defined scope and memory space and cannot interact with other SPIDs. Everytime an application connects to SQL Server, a new connection (or SPID) is created. These process ID’s are essentially sessions in SQL Server.
