Export Sql query to several excel files - mysql

Question

I have 2 tables:
company (rut, name, category, city)
categories (category).
I need to export an excel file for each category with the corresponding companies.
I have the query:
Select * from company c
inner join categories cy on c.category = cy.category;
That is not what I need But each group of combinations is exported to a different excel file.
Thank you.

Answer 1

If you want to export it one by one use this code:
SELECT * FROM COMPANY WHERE CATEGORY = (NAME OF CATEGORY);
If you want to export all:
SELECT * FROM COMPANY ORDER BY CATEGORY ASC;
I dont think you need to join it to "categories" table since you already use the same value from table company.
You can now export your result set.

Answer 2

There are a couple things you can do here.
You can do a big dump to Excel, and copy all unique values in a specific column to a new workbook.
Sub Copy_To_Workbooks()
'Note: This macro use the function LastRow
Dim My_Range As Range
Dim FieldNum As Long
Dim FileExtStr As String
Dim FileFormatNum As Long

Dim ws2 As Worksheet
Dim MyPath As String
Dim foldername As String
Dim Lrow As Long
Dim cell As Range
Dim CCount As Long
Dim WSNew As Worksheet
Dim ErrNum As Long
'Set filter range on ActiveSheet: A1 is the top left cell of your filter range
'and the header of the first column, D is the last column in the filter range.
'You can also add the sheet name to the code like this :
'Worksheets("Sheet1").Range("A1:D" & LastRow(Worksheets("Sheet1")))
'No need that the sheet is active then when you run the macro when you use this.
Set My_Range = Range("A1:D" & LastRow(ActiveSheet))
My_Range.Parent.Select

Also, you can split a table/query into several separate Excel files using SSIS. I'm not sure you can do this kind of thing using pure SQL.
I suppose you could use Excel to create queries with where clauses, and filter for all unique records in a table, export each unique batch to worksheet, and then save each worksheet as a separate file. I can imagine that it would run pretty slow on a large table.
