Concatenate vertically in macrovariable

[Planck]

Oh ok thanks for answer,

I am used to put some commas. But even, when I try your method i get an error.

The first query works well. I get the result: 1 5 13

But after when I run the second query so I have:

WHERE mydata IN (1 5 13)

And I get the error:

ERROR: Expression using IN has components that are of different data types.

because mydata is character.

If your data is character you need the quotes.

The error message explains the problem.  You cannot use numeric literals in the IN list if the variable being compared is character. You need to use character literals.

WHERE mydata IN ("1" "5" "13")
