I have a script that loops through *.sql files in a folder. It's OK if I do not alias the column result but will only run the first SQL file if I do use aliases.
#Loop through the .sql files and run them
foreach ($filename in get-childitem -path $FolderPath -filter "*.sql" |sort-object) {
invoke-sqlcmd –ServerInstance $SQLServer -InputFile $filename.fullname
}
Two files are currently in the folder.
The results of ALIASES:
You
-------
Hello World
The first SQL file:
select 'Hello World' as [You]
The second:
select 'Hello You' as [Me]
This is SUCCESSFUL when columns not aliased:
Column1
-------
Hello World
Hello You
The first SQL file:
select 'Hello World'
The second:
select 'Hello You'

Do you get any error or warning messages?

NO, but it did not give the results from the second file.

The first execution is defining the output object - a column called 'You'. As the second execution doesn't match that output you don't see it in the results.
No alias or the same alias you'll get both.

This will return the first column from each query, regardless of name:
$FolderPath = 'C:\users\lyonsg\Documents\Scripts\Powershell\HelloWorldTest\'
#Loop through the .sql files and run them
foreach ($filename in get-childitem -path $FolderPath -filter "*.sql" | sort-object) {
(invoke-sqlcmd –ServerInstance $SQLServer -InputFile $filename.fullname).Item(0)
}
If you need more than one column might be more complicated.
