I want to create a database with 5000 entries (coupons) and 6 columns for each entry. The first column entry is to be numbered from 1 to 5000. The second column in each entry is a unique 11 digit code. All other column entries are identical for every coupon.
If i create an entry in phpMyadmin, then copy it and change the first column entry to increment it by one for the new coupon, and add the new 11 digit code to the second column entry and save as new entry, it is faster than creating an entirely new entry from scratch, but it will still take ages to repeat this 5000 times.
I have each of the 5000 unique codes in a word file. Is there a way to duplicate one of my coupon code entries 5000 times incrementing the first column entry by 1 (ie from 1-5000), then uploading the 5000 unique 11 digit codes, and assign a unique 11 digit code to the second column of each of the 5000 entries?
Why not just turn your .word file into a .csv file and then upload it into your database using the "import" option? You could get all your coupons on the database,since I'm guessing you will be using them later on anyways?

Summary
I have a database of ~1500 entries. Some of them have more than one entry (up to 5) under the same identifier. I have a pre-set list of IDs I would like to check to see if they have multiple records, and if so, pull all of them, so I can compare them for differences.
Current solution
I currently have this working correctly, using a method to pull the 1st, 2nd, 3rd, 4th and 5th response respectively. The current formula is:
=INDEX('DATABASE'!$B:$B,SMALL(IF($A2='DATABASE'!$A:$A,ROW('DATABASE'!$A:$A)-ROW('DATABASE'!$A$1)+1),1)) for the 1st result, =INDEX('DATABASE'!$B:$B,SMALL(IF($A2='DATABASE'!$A:$A,ROW('DATABASE'!$A:$A)-ROW('DATABASE'!$A$1)+1),2)) for the second, and so on. In this case, the above code would check the value in A2 (ID2Check), and then do a match for it on the 'DATABASE' sheet in column A. If it matches, it will return the first value that matches from column B. The second piece of code above does the same, except it returns the second match from column B. ID2Check is populated by me, and the Results 1-5 are the code output. For example:
Database:
ID
Data Item
AAA
Lemons
111
Greenhouse
FOO
Computer
AAA
Monitor
CAT
Coffee
ORANGE
Pintglass
123
Birthday
FOO
Avengers
AAA
Plasters
FOO
NachoTaco
Code output:
ID2Check
Result 1
Result 2
Result 3
Result 4
Result 5
AAA
Lemons
Monitor
123
Birthday
FOO
Computer
Avengers

Problem
This solution works correctly, and will pull the expected values as required. The problem is, as this code needs to be entered 5 times per identifier, and there are ~1500 records to check, I need to flash fill 7500 formulas. Unsurprisingly, this leads to Excel crashing and becoming unresponsive for the best part of 30 minutes. I am looking to find a solution that would be more efficient and stable when running en-mass. Any assistance would be appreciated.
Final Notes / Info
I'm using MSO 365, version 2202 (I cannot update beyond this). This will be run in the Desktop version of Excel. I would prefer this is done exclusively using formulas, but I am open to using Visual Basic if it would be otherwise impossible or incredibly inefficient.
=UNIQUE(C5:C15)
=TRANSPOSE(FILTER($D$5:$D$15;$C$5:$C$15=F5))
If you have access to HSTACK() function then could try-
=HSTACK(UNIQUE(A2:A11),TEXTSPLIT(TEXTJOIN("/",FALSE,BYROW(UNIQUE(A2:A11),LAMBDA(x,TEXTJOIN("|",TRUE,FILTER(B2:B11,A2:A11=x))))),"|","/",,,""))
I'm using this formula =IF(B24="","",IFERROR(INDEX(Sheet3!$C$3:$EE$3,,MIN(IF(Sheet3!$C$4:$EE$23=(Sheet2!C24&$K$18),COLUMN(Sheet3!$C:$EE)))-2),"NF")) to return a cell value in the top row of an array - a date in this case.
The search criteria is a combination of a unique project number and a 2 digit status alphanumerical code for the project. The array consists of 23 rows where combinations of the unique numbers are found, each with different status codes.
So essentially, I'm building a FILTERED project status dashboard that returns dates linked to the relevant project status.
The code above is inspired from ( LINK ) that uses a very similar layout, but it uses town suburbs linked to postal codes instead of project numbers and status codes. The formula works well (though, not entered as an array formula), but I don't have a single formula in the sheet, I have 3 300 occurrences of this formula.
The problem comes in when the user changes the FILTER - Excel recalculates the entire dashboard and that takes anywhere from 2 to 5 minutes to run. You hit the escape button and cancel the calculation after setting the filter, but Excel just starts calculating again after a few seconds. After that, Excel's response is sluggish and almost unusable. Yes - our hardware is pretty weak ...
I tried XLOOKUP as well, but can't set the "lookup_array" to an array ( Sheet3!$C$4:$EE$23 ) because it doesn't match the "return-array" ( Sheet3!$C$3:$EE$3 ) Concatenating the lookup arrays with & works, but then you'd have to do that for all 23 rows, and again, multiply that by 3 300.
I thought of creating a UDF, but the function will still be called every time Excel recalculates after filtering... 3 300 calls ...
Any ideas on how to make the INDEX version run faster, or make the XLOOKUP accept the lookup_array as Sheet3!$C$4:$EE$23 in the hopes that it'll run faster?
Thank you!
Not really an elegant solution, but it works.
I imported the dataset into a helper sheet, where I combined the cell value with the corresponding value in Column A for each row ( a name in this case ) and the date from row 1 for each column, using underscore as a delimiter.
This new data range was then given a unique name, EE in this case.
On a second helper sheet, using this formula =INDEX(Filtered,1+INT((ROW('Sheet1'!C3)-1)/COLUMNS(Filtered)),MOD(ROW('Sheet1'!C3)-1+COLUMNS(Filtered),COLUMNS(Filtered))+1) and drag it down till it returns an REF! error and going back one row before the error.
This transposes all the data into a single column G. Using =UNIQUE(SORT(FILTER(B3:B3240,B3:B3240<> "",""))) then gives me a filtered list of unique values in column H that I then run
=IF(H3="","",LEFT(H3, SEARCH("_",H3,1)-1)) for the first data value in I, and
=IF(H3="","",MID(H3, SEARCH("_",H3) + 1, SEARCH("_",H3,SEARCH("_",H3)+1) - SEARCH("_",H3) - 1)) for the middle data value in J, and
=IF(H3="","",IFERROR(TEXT(RIGHT(H3,5),"yyyy-mm-dd"),"NF")) for the last data value in K.
Then just run XLOOPUP across columns I, J and K.
Runs quick and easy and solves a few of the other issue I had as well.
The second data set has just over 35 000 rows - still works well and fast.
I would need your help with and SQL query that has to remove duplicate entries from a table, mostly using the datestamp column as a criteria in two passes.
Microsoft SQL DBMS is in question.
Here is a little more details:
Terminology: Module is basically a group of single machine workplaces onto which users operate.
Table:
ModNam column is fixed, there are 15 modules from M A01 to M A15, then goes the B row M B01 ... M B15 and so on until row F.
Pos column is irrelevant at the moment.
MdCod column represents a code of the machine being added to the position in the certain module. It can be replaced by another machine at any given time.
I have one query that will be inserting data into this table by copying entries from another table, every time a new machine is added to one of the positions.
Tricky part for me is a second query that should be comparing records in two phases and if:
1) Inside same module (first pass of the query represented with red color in the example pic attached):
ModNam value is the same, MdCod matches between the entries then the most recent datestamp decides the single one to stay and others duplicates get deleted
2) Inside other module (second pass of the query represented with purple color in the example pic attached):
ModNam values are different and MdCod matches between the entries then the most recent datestamp decides the single one to stay and others duplicates get deleted.
Please help and advise.
Example pic (updated):
Thank you all in advance.
My data file looks like
1234567 7654321
TEXT ABOUT STUFF
ON MULTIPLE LINES
NOT SURE HOW MANY
1234567 7654321
TEXT ABOUT STUFF
ON MULTIPLE LINES
NOT SURE HOW MANY
The only thing for certain is a new record starts with 2 sets of numbers that are 7 characters long. The numbers are also on a new line and appear as my sample data above.
I am using SQL Server Express on Windows 8.
Ultimately I need the first group of numbers in a column, 2nd group in another column and the remainder of the text in the 3rd column.
This is the realm of ETL. The SQL Server was of doing this is to use SSIS.
I have tried looking for an answer for my question but due to lack of proper knowledge in databases, I thought some genius here could help me out.
I'm trying to add rows into a database table starting from the number 800 and onwards in a sequential order. The database currently has records from 1 up until 300.
This record in the table is not automatically incremented, but assigned manually.
I basically want to start another batch of numbers, but rather than incrementing them from where the program left off (i.e. from 300) I would like to start them from 800.
I tried different SQL statements but got nothing concrete to go with. I'm using PHP to enter these rows.
I feel like this shouldn't be so hard but I'm a novice and it kills!
I thought maybe adding one record that starts from 800 and then executing a statement like
SELECT LAST FROM A RANGE BETWEEN 800 AND 899
would be the way to go.
Any help, advice?
You can obtain the highest numbered record with the MAX aggregate function. The following will find the next highest number that is between 800 and 899.
SELECT MAX(my_assigned_number) + 1 as next_number
FROM my_table
WHERE my_assigned_number > 800 AND my_assigned_number < 899;
