The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Asked by No_hope in SQL Query Syntax, Microsoft Access Database

Tags: , ,

Since I posted my question in wrong zone and did not get answer I was hoping for I repeat my question.
So, I have two tables

T_1
WELL1            DT_1                    TEMP          MEAS_ID_NUM
A1                 3.7.2007                 5                 1
A1                 2.9.2007                 4.5              2
A5                 15.4.2006               6                 3
etc.

T_2
WELL2              DT_2                    WTRLVL
A1                  3.7.2007                 88
A1                  30.8.2007               88.5
A1                  3.11.2007               88.1
A1                   1.12.2007              88.4
A5                  20.4.2006               76
A5                  7.6.2006                 76.3
A5                  13.9.2006               75.9

Is it possible to create sql statement where I can find just the nearest match for wells and dates in table T_1 from table T_2 and join these two tables:

WELL1              DT_1                        DT_2            WTRLVL          TEMP                MEAS_ID_NUM
A1                  3.7.2007                  3.7.2007         88                    5                         1
A1                  2.9.2007                  30.8.2007       88.5                 4.5                      2
A5                15.4.2006                  20.4.2006       76                    6                         3
etc.
