为什么'sqlmock”无法匹配查询，即使查询相同并且日志显示它们相同？

Why is `sqlmock` failing to match a query even though the queries are identical and the logs show them to be the same?

sqlmock 不匹配查询，但查询相同且日志输出显示相同

在编写使用 Gorm 和 sqlmock 测试代码时遇到一个问题，主要是有关更新函数。

第一个工作流部分仅从数据库中查询记录。即使日志输出显示它们相同，我也无法使其与我的 SQL 匹配。

错误信息如下：

(database.go:263)
[2020-01-08 10:29:40]  查询：无法匹配实际 SQL：“SELECT * FROM "storage_pools" WHERE "storage_pools"."deleted_at" IS NULL AND ((poolid = ?)) ORDER BY "storage_pools"."id" ASC LIMIT 1” with expected regexp "SELECT * FROM "storage_pools" WHERE "storage_pools"."deleted_at" IS NULL AND ((poolid = ?)) ORDER BY "storage_pools"."id" ASC LIMIT 1"

我也尝试使用 ExpectExec 插入 ExpectQuery。

  for _, c := range cases {
    db, mock, err := sqlmock.New()
    if err != nil {
      t.Fatal(err)
    }
    DB, err := gorm.Open("sqlite3", db)
    if err != nil {
      t.Fatal(err)
    }
    DB.LogMode(true)

    mock.ExpectQuery(`SELECT * FROM "storage_pools" WHERE "storage_pools"."deleted_at" IS NULL AND ((poolid = ?)) ORDER BY "storage_pools"."id" ASC LIMIT 1`)

    err = UpdateStoragePool(DB, &c.givenPool)
    if !reflect.DeepEqual(c.wantedError, err) {
      t.Fatalf("expecting errror %q, got %q", c.wantedError, err)
    }

    // 如果事务期间没有发生任何错误，则检查是否满足所有预期
    if c.wantedError == nil {
      if err := mock.ExpectationsWereMet(); err != nil {
        t.Fatalf(err.Error())
      }
    }
  }

我也试过：

mock.ExpectQuery(`SELECT * FROM "storage_pools" WHERE "storage_pools"."deleted_at" IS NULL AND ((poolid = '1')) ORDER BY "storage_pools"."id" ASC LIMIT 1`).WithArgs(1)  
mock.ExpectExec(`SELECT * FROM "storage_pools" WHERE "storage_pools"."deleted_at" IS NULL AND ((poolid = ?)) ORDER BY "storage_pools"."id" ASC LIMIT 1`)  
mock.ExpectExec(`SELECT * FROM "storage_pools" WHERE "storage_pools"."deleted_at" IS NULL AND ((poolid = '1')) ORDER BY "storage_pools"."id" ASC LIMIT 1`).WithArgs(1)
