Powershell foreach INSERT INTO SQL Server DB on multiple rows - sql

Question

I am trying to insert 2 separate arrays into multiple records on 1 SQL Insert Command. I have done the foreach command but it will only accept 1 of the arrays. I have tried doing nested foreach statements but that just puts in way to many records. Below is the code I have so far. I am not posting my connection code to my DB but I ensure you that it connecting to the DB.
$array1 = #(1,2,3)
$array2 = #(a,b,c)
foreach ($file in $array1)
{
$SqlQuery.Append("USE $SQLDBName;")
$SqlQuery.Append("INSERT INTO tbl_File(Column1, Column2, Column3)")
$SqlQuery.Append("VALUES('Dummy Data', '$file', '$array2');")
}
What I am most confused about is how to make both arrays parse correctly into the DB. I hope I explained that correctly. Anything helps!
Here is an example of what it will need to look like:
Column 1 | Column 2 | Column 3
Dummy Data User Input1 User Input1
Dummy Data User Input2 User Input2
Dummy Data User Input3 User Input3
This is what I want it to look like with Column 2 being the first array and column 3 being the second array. Column 1 will always be the same.

Answer 1

revised based on your comments. should be easy to put into a sql stmt
This the way to pull values from the two arrays side by side for each index position
$array1 = #(1,2,3)
$array2 = #('a','b','c')
$counter = 0;
foreach ($file in $array1)
{
Write-Host $file $array2[$counter]
$counter +=1;
}
if you want an entire array stored in a column, you would need to convert possibly to string an delimit it
$array1 = #(1,2,3)
$array2 = #('a','b','c')
$counter = 0;
foreach ($file in $array1)
{
Write-Host $file ([string]::Join(',', $array2))
$counter +=1;
}

Answer 2

Based on the newly added expected result
$array1 = #(1, 2, 3)
$array2 = #("a", "b", "c")
$sqlQuery = [System.Text.StringBuilder]::new()
$sqlQuery.AppendLine("INSERT INTO tbl_File(Column1, Column2, Column3)")
$sqlQuery.AppendLine("VALUES ")
$hash = #{
A1 = $array1
A2 = $array2
}
$counter = $array1.count # Supposedly both arrays always contain same number of elements.
for ($i = 0; $i -le $counter - 1; $i++)
{
$sqlQuery.AppendLine("('Dummy Data', '" + $hash['A1'][$i] + "', '" + $hash['A2'][$i] + "')")
}
$sqlQuery.ToString();
Result is:
INSERT INTO tbl_File(Column1, Column2, Column3)
VALUES
('Dummy Data', '1', 'a'),
('Dummy Data', '2', 'b'),
('Dummy Data', '3', 'c')
(Old solution) Based on your comments I think this is the result you want in your table:
Column1 Column2 Column3
Dummy Data 1 2 3 a b c
This PS script generates the INSERT statement you need:
$array1 = #(1, 2, 3)
$array2 = #("a", "b", "c")
$sqlQuery = [System.Text.StringBuilder]::new()
$sqlQuery.AppendLine("INSERT INTO tbl_File(Column1, Column2, Column3)")
$sqlQuery.AppendLine("VALUES ")
$sqlQuery.AppendLine("('Dummy Data', '" + "$array1" + "', '" + "$array2" + "')")
$sqlQuery.ToString();
Result is:
INSERT INTO tbl_File(Column1, Column2, Column3)
VALUES
('Dummy Data', '1 2 3', 'a b c')
