• What you are looking at is NOT the hard drive serial number.

• It is called the Volume Serial Number. It is generated at the time of creating and formatting the volume / partition.

• You can get it by using a command at command prompt : C:> vol c: if C: is the drive you want to retrieve the Volume Serial Number for.

  Summary: in this tutorial, we will show you how to use the PostgreSQL ADD COLUMN statement to add one or more columns to an existing database table. Introduction to the PostgreSQL ADD COLUMN statement. To add a new column to an existing table, you use the ALTER TABLE ADD COLUMN statement as follows. If you omit any column that accepts the NULLvalue in the INSERT statement, the column will take its default value. In case the default value is not set for the column, the column will take the NULL value. PostgreSQL provides a value for the serial column automatically so you do not and should not insert a value into the serial column. Introduction to the PostgreSQL SERIAL pseudo-type. In PostgreSQL, a sequence is a special kind of database object that generates a sequence of integers. A sequence is often used as a primary key column. The concept of the sequence in PostgreSQL is similar to. The copy command allows you to specify which columns to populate. If you omit the id column, it will be populated with the values from the sequence: copy pricing_cache (column_1, column_2) from stdin with csv col_1_value,col_2_value col_1_value,col_2_value. You haven't shown us your complete table definition.

• All you can do is redirect the output of that command to a file : C:> vol c: > myvol.txt and it will be stored as a text file in your C:

• I am attaching a screenshot with the highlights:

• The file was stored in the root of C:

• This is what the myvol.txt file looks like in Notepad:

In a batch file one approach is:

1. VOL command to produce the serial number as text along with text we don't want.
2. FIND to trim it down to only the line with the serial number.
3. FOR to grab the 5th token (a part between delimiters) on the line with the serial number.
4. SET to assign to an environment variable

In the same vein as Moab's answer, but using PowerShell this time:

This command gets an instance of the Win32_DiskDrive WMI class and outputs the model of each disk drive in the computer and its corresponding serial number from that instance.

This answer assumes PowerShell 3.0 or later. If running an older version, use Get-WmiObject in place of Get-CimInstance.

On Windows 8 and later, you can also use this command:
