Opening Management Studio
Connecting to database
Credentials
Structure
– Database -> Folders ->Tables ->Columns
Changing User Settings

Changing User Settings
• Displaying line numbers if they aren’t

– As you begin your query, IntelliSense will provide you with a dropdown
list of options that are similar to what you’ve begun to type. This is
similar to how Autofill works in Excel.
Changing User Settings
• Updating query run times.
– Can shorten the amount of time it takes for your query to
come back if the table contains a large data set.
Important Buttons
• New Query
• Execute
• Stopping a Query
Basic Selections
• Select * From [Table];
• This will select all columns from the named table
• Select [Column]
, [Column]
, [Column]
From [Table];
• This will select the listed columns from the named table
• Note: Columns with spaces, dashes or other special characters
in their name must be enclosed in a brackets due to naming
conventions of SQL Server. Otherwise the brackets are optional.
Select using “where”
• Select * From [Table] where [Column] <operator> ‘text string’;
• This will select all columns of data from the named table if the named
column data matches the operator and text string you entered
(ex: [Company] = ‘Sample Company’)
• Operators
•
•
•
•
•
•
= (Equals)
<> (Not equal)
< (Less than)
> (Greater than)
<= (Less than or equal to)
>= (Greater than or equal to)
Aggregate Functions
• Sum ( [Column] )
• Will add every value in the particular column
• Count ( [Column] )
• Will give the total number of fields that are not null. If you
want to count the number of rows use count *
• Max ( [Column] )
• Min ( [Column] )
• Avg ( [Column] )
• These will give you the max, min, or average of the data.
Using Group by
• When using the aggregate functions in a select
statement, all fields that are not being aggregated
must be included in a group by clause.
• Select
[Column1]
, <aggregate function> [Column2]
From [Table]
Group by [Column1];
Caution!
If you are selecting multiple tables you
should be using a “join” statement in order to
limit the amount of time a query takes to run.
Intro Joins
• Joins
– Link two tables together on a named column that both tables
share
• Inner Join
– Returns the data set of records in the first table that have a
related record in the second table.
Intro Joins
• Left Outer Join
– Returns the entire dataset of the first table. If there is a
not a related record in the second table it returns “NULL”
