Default How to write T-SQL to retrieve the required Output

Hi all!

I am using tables "OptionsMapping" (Id, Category, Name), "Person" (Id, Name, Add etc) and "STRENGTHANDCONDITIONINGDAILY" (PersonId, Date, MorningId, AfterNoonId) to retrive required results through T-SQL.



OptionsMapping table



Id Category Name

1 1 Pre-activation

2 1 Lower Body Strength

3 1 Upper Body Strength





Person Table



Id Name Add

1 Amit New Delhi

2 Sachin New Delhi

3 Santosh New Delhi





STRENGTHANDCONDITIONINGDAILY



PersonId Date MorningID AfterNoonId

2 2008-06-23 00:00:00 1 2

2 2008-06-24 00:00:00 3 1

3 2008-06-23 00:00:00 2

3 2008-06-24 00:00:00 3 1







I want to output as follows with T-SQL -



Player Pre-Activation Lower Body Strength Upper Body Strength Total

Sachin 2 1 1 4

Santosh 1 1 1 3





In above, Except Player and Total headers all are comming dynamically from optionsMapping tables and it's calculated values are comming from "STRENGTHANDCONDITIONINGDAILY" table. How to calculate For example Person id 2 is Sachin has attempt option Pre-Activation 2 times, Lower Body Strength 1 times and Upper Body Strength 1 times. So total activity is 4. Similarlly for all person I want to display through T-SQL.



Please help me to write T-SQL?



Thanks in advance

This could be really easy if you know ahead of time that you only care about ID's 1,2,3 in the OptionsMapping table. But assuming that this table is dynamic--that you can add new options in new categories at any time--then it's much much more difficult.

So... ARE the categories FIXED? Or do you need to handle dynamic mappings??

[ Your design for StrengthAndConditioningDaily is also less than ideal for the purposes of this task, but it's at least usable. ]

First of all thanks for quickly reply....

No categories are not fixed. I need handle it dynamic mappings.

Here I want result(Output) columns except "Player" and "Total" columns all come dynamically from the OptionsMapping table.

If you are talking about "Cetegory" column of "OptionsMapping" table. It can be fixed if easier to implement T-SQL. Since I am inserting options in "STRENGTHANDCONDITIONINGDAILY" only for one category.But options are not fixed it can be any number for one cetegory.


Thanks a million ton

I think this will be really tough to do all in SQL.

The only way I see to do it is to first build the SQL statement needed to create a TEMP table with the appropriate columns. You do that by examining your OptionsMapping table for the given category.

And then you'll create one row in your TEMP table for each person from the Person table.

And then finally you'll have to run a cursor through the StrengthAndConditioningDaily table that UPDATEs the appropriate row and columns in the TEMP table.

This would be 10 times easier to code in some reporting system, such as ASP or PHP or JSP or ASP.NET, than it is in SQL code. *MUST* it be in T-SQL???
