In the project, use the addAll () method for operations, and enable transaction processing. Roll back if the addAll () method is not completely inserted successfully. How can I determine whether all addAll () is successfully inserted. Maybe there are other good solutions? In the project, use the addAll () method for op
The AddAll () method is used in the project, and transaction processing is turned on.
If the AddAll () method is not fully inserted successfully, it is rolled back.

Maybe there are other better options?

First, the four-dimensional array is converted into a two-dimension array.
In this case, you have to handle the array yourself.
Use Array_reduce () down to two-dimensionalThen use
When the author wrote a simple interface to create a problem in the project, he accidentally stepped on the thinkphp's two pits. It's called a pit, but it's not familiar to the document. The interface code is as follows:
Public Function Createproblems () { $problems = I (' json. '); if (empty ($problems)) { $this->error ($problems, ' JSON format does not conform to specification '); } foreach ($problems as $problem) { $data = D (' problem ')->create ($problem, self::o
In the Java Collection framework, there are three similar methods, addall (), retainall () and removeall (). addall (), the retainall (), and The removeall () methods are equivalent to the set theoretic union, intersection, and complement operators, respectively. these are already strated in the following picture. In my local machine, just for these methods, I made a test for them respectively. Package
There are two sets, if one of the parameters of set A is repeated with the parameters of the other set B, then subtract their repeated arguments, and the remaining parameters form a new set C.Set1.removeall (Set2)You can delete all parameters that are duplicated inside Set1 and Set2.If you need a collection, it can be simple.Set1.addall (Set2); So the Set1 inside is all the parameters.The Java code is as follows:Package com.javaCode.package05;Import j

Background: There are often such requirements, we need to copy the value of the set A to set B, or to the collection of multiple arrays to the statistical value, then it is not feasible, just yesterday a friend encountered a mistake, we discussed together.
Normally, we implement adding the value of collection A to the set B, which is the case:
listList3.add ("1");listList4.add ("2");List3.
