加入四個具有相同列，不同條件的MySQL查詢

Question

我有四個查詢，每個查詢有6列。除WHERE子句在每種情況下略有不同外，每個查詢都是相同的。我希望看到的是eachother旁邊的每個列的每個查詢結果進行比較。示例結果表頭：time（only one），calls1，calls2，calls3，calls4，work1，work2，work3，work4，tele1，tele2，tele3，tele4，comm1，comm2，comm3，comm4，techs1，techs2 ，techs3，techs4。

實際查詢如下。請幫我做一個比較性的查詢。牛逼

你可以使用「CREATE TEMPORARY TABLE TableName1」爲每個表，然後編寫一個查詢把列順序然後刪除該表時，你完成。
