Hello,

I would like known when I export data from SQl to datagriview will automatic add a number after header name. Some headers have same name and in datagrid look like: Nazev1, Nazev2,Nazev3 why? I want only name: nazev. - auto renaming to Nazev 1, Nazev2. How can I fix it?

thank you

What I have tried:

Define in SQL

VPrikazMzdyAZmetkyPostup.nazev AS [Nazev]

VPrikazMzdyAZmetkySmena.nazev AS [Nazev]

When you write your SQL SELECT query you specify the header text (assuming you use a DataTable or DataSet as the DataSource):

SQL

SELECT A, B, C FROM MyTable

Will give you a DGV like this:

A   B   C
1   2   3
4   5   6

When you want specific text, you use AS:

SQL

SELECT A AS [Column number one], B AS [Charles XII], C AS Hello FROM MyTable

And you will get the headers:

Column number one    Charles XII    Hello
                1              2        3
                4              5        6

Depending on the usage context, you may not be able to have multiple columns with the same name- an instance would be when it is a control which must have a unique name.
Can I have multiple DataGridViews with columns with the same name? : csharp[^]

Of course, there is always trickery that can be used to overcome this
