Since I have been using the reporting service for a while, I have always felt that My SQL statements have become very popular.
It was a very simple thing that made me think about the morning.
When neededBatch update a field in an existing tableLet's do it. I thought it was very simple. I had a lot of problems.
If a problem occurs, it is not the point. The point is that my attitude towards the problem is incorrect. Therefore, we need to record it for future reflection.
People should be modest and not proud. If you are a little achievement, you will not know the depth of the sky. I think that the second child of the earth is my old three. The necessary self-motivation is needed, but we should also avoid self-arrogance mistakes.
Always remind myself that I am the best, and be mentally alert that I cannot be arrogant. There are still many things to learn.
Finally, post this small question:
Code
Update Table1
Set col=T2.colvalue
From Table1
Inner join (select table2.idkey, table2.colvalue
From table2) T2
On table1.idkey=T2.idkey
In a person's entrepreneurial journey, we will have a lot of achievements. It is worth noting how to deal with these achievements.
We have to be sure of it. Only by being sure of yourself can you be more confident and motivated to meet more challenges. But at the same time, remind yourself that this is just the beginning, there are still many things to do, and the road is still very good.
Long. To avoid yourself from being comfortable, arrogant complacency is the biggest resistance in the process of moving forward. This is actually a small problem, so no one pays attention to it. Once you do not pay attention to changing your mindset, many things may change.
The journey to start a business is far away. We need to try our best to avoid making small mistakes. Mentality affects decisions to a large extent. An inadequate battle may be initiated due to a burst of enthusiasm.
Loss of a great business opportunity.
