如果遇到这个错误,需要检查当前在存储函数或触发器中执行的SQL操作,看是否有上述导致隐式提交的语句。 4. 修改建议 为了避免在存储函数或触发器中进行提交操作,可以采取以下策略: 避免使用会导致隐式提交的语句:在编写存储函数或触发器时,应避免使用那些会导致隐式提交的SQL语句。 重新设计逻辑:如果确实需要在事务中...
Note that some data types can only be combined in a single expression by using an explicit conversion and that some data types are not compatible at all with or without an explicit conversion. ThisBooks Online pageincludes a compatibility matrix showing all of the possible data type combinations....
Corresponding columns in the result sets that are being combined with UNION, or any subset of columns used in individual queries, must be of the same data type, have an implicit data conversion possible between the two data types, or have an explicit conversion supplied. For example, a UNION...

First published on MSDN on Jun 05, 2008 In my last couple of posts, I wrote about how explicit conversions can lead to errors.

参考https://zh.cppreference.com/w/cpp/language/explicit 与隐式转换对应出现的就是explicit关键字,既然提供了隐式转换,那么肯定也有禁止隐式转换的方法。explicit关键字就是声明在构造函数前,明确指定,不允许隐式转换构造,必须是明确的 4.user-defined conversion ...
The problem happens not only withnull as col1, but also with varchar conversion like'' as col1or'42' as col1. As a workaround it is possible to use the explicit cast totinyint, it is trivial to do it in static T-SQL, and not so trivial in Entity Framework queries (can be done...
Same example is given below for explicit cursor but with For Loop, the For Loop cursors are more smart as there is no need to declare variables to fetch values in them and no need to open or close or to check whether the pointer is at end of the cursor. Here is the example: ...
If performance is affected, then you’ll need to rewrite the query to make any conversion explicit and to ensure that all your filter predicates are of the right datatype!Now we can query it for all plan_affecting_convert events, and include the text of the SQL batch that caus...
