Question

正如标题所述，我在查询时遇到了麻烦；

我尝试过更改temp_ob的排序规则以达到相同的效果。

请告知如何解决此问题。

请注意，我将在存储过程中使用它。

   $.get(newUrl, function (data) {
    $("#ProductsPartialView").empty();
    $("#ProductsPartialView").append(data);
    $('#loadingModal').modal('hide');

}).fail(function (xhr, err) {
    alert("readyState: " + xhr.readyState + "\nstatus: " + xhr.status);
    alert("responseText: " + xhr.responseText);
});

MYSQL版本 8.0.16

默认排序规则 utf8mb4_0900_ai_ci

默认字符集 utf8mb4

表排序规则 utf8mb4_unicode_ci

在Mysql Workbench中运行查询时收到的错误
