Read a CSV file and dynamically generate the insert

Question

I have a requirement where there are multiple csv's which needs to be exported to a sql table. So far, I am able to read the csv file and generate the insert statement dynamically for selected columns however, the insert statement when passed as a parameter
to the $cmd.CommandText
does not evaluate the values
How to evaluate the string in powershell
Import-Csv -Path $FileName.FullName | % {
# Insert statement.
$insert = "INSERT INTO $Tablename ($ReqColumns) Values ('"
$valCols='';
$DataCols='';
$lists = $ReqColumns.split(",");
foreach($l in $lists)
$valCols= $valCols + '$($_.'+$l+')'','''
#Generate the values statement
$DataCols=($DataCols+$valCols+')').replace(",')","");
$insertStr =@("INSERT INTO $Tablename ($ReqColumns) Values ('$($DataCols))")
#The above statement generate the following insert statement
#INSERT INTO TMP_APPLE_EXPORT (PRODUCT_ID,QTY_SOLD,QTY_AVAILABLE) Values (' $($_.PRODUCT_ID)','$($_.QTY_SOLD)','$($_.QTY_AVAILABLE)' )
$cmd.CommandText = $insertStr #does not evaluate the values
#If the same statement is passed as below then it execute successfully
#$cmd.CommandText = "INSERT INTO TMP_APL_EXPORT (PRODUCT_ID,QTY_SOLD,QTY_AVAILABLE) Values (' $($_.PRODUCT_ID)','$($_.QTY_SOLD)','$($_.QTY_AVAILABLE)' )"
#Execute Query
$cmd.ExecuteNonQuery() | Out-Null

Hi Jyeragi,
To convert the data to the SQL table format, please try this function out-sql:
out-sql Powershell function - export pipeline contents to a new SQL Server table
