QUESTION

Macro to rearrange columns in sequence

Asked 2020-Dec-01 at 10:31

I am new to VBA, Macro, Excel... all I am trying is to rearrange columns in sequence... so I have declared column name at first then the column range and tried to Cut, Insert/Paste the columns by their name one after another. The macro just executes does not give the desired output, as I am predicting that columns get shuffled. Then, I tried to cut all 24 columns at once and paste them in sequence one after another which unfortunately does not work. Then, I decided to cut a range of columns from that main sheet create a new sheet and paste there then cut single columns from that sheet and paste it back in the main sheet which is also not working. I am able to cut and paste the columns in the new sheet but not able to paste the columns in sheet "Main".

My Codes 1 - This is the code I tried to copy cut paste the column which executes but does not give the result.

Please, test the next code. The code should be very fast, using arrays, working only in memory and dropping the processing result at once. It will return the result at the end of the sheet range, after the existing rows. After testing the code and consider it reliable, you can simple change the cell where the arrFin array content is dropped. From sh.Range("A" & lastRow + 2) in sh.Range("A1"):

QUESTION

Alternative to database table joins while filtering data

Asked 2017-Sep-12 at 14:09

We have a portal where member signup. The members than participate in topics, discussions, get rewards etc. I guess similar to stackoverflow or other forums. Each of our client can customise the portal. One of the customisable option is member profile fields.

Any number of profile fieldS can be added in a portal, as this is done by clients. More than 10 is not uncommon.

Problem is related to filtering members based on these profile fields. If I have many profile fields in portal and the filter has lots of criteria the database query just doesn't work in realtime. For e.g. if the below database query takes 10.57 secs to complete with filter for 10 profile fields:

The EXPLAIN shows that your indexes do not cover the query. This means that for every filter field you add, the server has to do much more work; it also means that adding indexes that cover the query should speed up the index dramatically.

Database engines are really good at joins. The "relational" part in RDBMS is all about that; as long as your joins can use indexes, they can handle huge numbers of joins on massive data sets.

Try adding the following index:
