Display information from a table and change the column names

In my database table I have two columns : ProdID and Prod. When I query the database to display the IDs and the product names, I would like to make the result a bit more 'User friendly' by changing the column names to 'Product ID and 'Product'. I do this in the following way :


Open query analyser.
Select the required database.

Select ProdID as 'Product ID', Prod as Products from Inventory

Display information in Upper and Lower case from SQL database

In my database table (products) I have a column called items that lists a number of products in sentence case. In order to display them in upper and lower case I do the following :

Open query analyser.
Select the required database.

Upper case

Select upper (item) from products

Lower case

Select lower (item) from products

Backup a database using a SQL command

In this example, we are backing up the database called 'Customers' to a location on the c: drive.

Backup database Customers to disk = 'c:\customer_backup.bak'

Get current date and time in SQL

There may be times where you will need to insert the current date and time into a database i.e. to record when a transaction has taken place. The command to display this timestamp is as follows :

select getdate() 'Current Date'

If you type this into query analyser you will get the current date and time in a column entitled 'Current Date'.

How do you copy a database table in SQL using code?

Open Query analyser
Select the required database (Use [databasename])

Type :

SELECT * INTO MyNewTable FROM MyTable

e.g SELECT * INTO Customer2 FROM Customer

How do you select all items from a SQL table ?

This is probably the first thing you will ever do with SQL and it's a nice easy one to get you started.

Open query analyser.
Select the required database (This can be done from the drop down menu or by typing "Use [database name"])

Type :

Select * from [table name]

This will now return all the records in the table.

Hide System Tables and Objects in MS SQL 2000 Enterprise Manager

Recently I have been working with SQL tables and stored procedures in Enterprise Manager. By default, the system and stored procedures are visible along with user-defined ones which make it fairly inconvenient when you are only interested in your own tables and stored procedures.

To make life a bit easier I thought I would find a way of hiding the system objects. The instructions are as follows :

1.  Right click on the "(Local)(WindowsNT)" in the Enterprise Manager.
2.  Select "Edit SQL Server Registration Properties," which opens up a property panel.
3.  Uncheck the option "Show system databases and system obejcts."
4.  Click OK
