Docs – SAVE TRANSACTION (Transact-SQL) Stack Overflow – SAVE TRANSACTION vs BEGIN TRANSACTION (SQL Server) how to nest transactions nicely 假设我们用 Stored Procedures 来封装小事务. 那在Stored Procedures 里面会是这样控制的. 1. 先查看当前是否有正在运行的 transaction. 通过 @@TRANCOUNT <> 0 来...
Temporary tables need this re-resolution so the table can be referenced from a nested stored procedure. Table variables avoid this step completely, so stored procedures can use plan that is already compiled, thus saving resources to process the stored procedure. Transactions involving table variables...
