动态 SQL - EXEC(@SQL) 与 EXEC SP_EXECUTESQL(@SQL)
在 SQL Server 中使用存储过程执行动态 SQL 命令的现实世界的利弊是什么
What are the real world pros and cons of executing a dynamic SQL command in a stored procedure in SQL Server using
EXEC (@SQL)
对比
EXEC SP_EXECUTESQL @SQL
?
推荐答案
sp_executesql 更有可能促进查询计划的重用.使用 sp_executesql 时，参数在调用签名中明确标识.这篇优秀的文章描述了这个过程.
sp_executesql is more likely to promote query plan reuse. When using sp_executesql, parameters are explicitly identified in the calling signature. This excellent article descibes this process.
