(use DataDirectory when your database file resides in the data directory)
Why is the "Database" parameter needed?
Answer:
If the database was previously attached, SQL Server does not reattach it
(it uses the attached database as the default for the connection).

Attach a database file on connect to a local
SQL Server Express instance:"Server=.\SQLExpress;
AttachDbFilename=c:\asd\qwe\mydbfile.mdf;
Database=dbname;
Trusted_Connection=Yes;"
- or -
"Server=.\SQLExpress;
AttachDbFilename=DataDirectorymydbfile.mdf;
Database=dbname;
Trusted_Connection=Yes;"
(use DataDirectory when your database file resides in the data directory)
Why is the "Database" parameter needed?
Answer: If the database was previously attached,
SQL Server does not reattach it (
it uses the attached database as the default for the connection).
Using "User Instance" on a local SQL Server Express instance:"Data Source=.\SQLExpress;integrated security=true;
attachdbfilename=DataDirectory\mydb.mdf;user instance=true;"
The "User Instance" functionality creates a new SQL Server
instance on the fly during connect. This works only on a local SQL Server 2005
instance and only when connecting using windows authentication over local named pipes.
The purpose is to be able to create a full rights SQL Server instance to a user
with limited administrative rights on the computer.
To enable the functionality: sp_configure 'user instances enabled','1' (0 to disable)
Using SQL Server 2005 Express? Don't miss the server name syntax:
SERVERNAME\SQLEXPRESS (Substitute "SERVERNAME" with the name of the computer)
- Context Connection - connecting to "self" from within your
CLR stored prodedure/function
C#:
using(SqlConnection connection = new SqlConnection("context connection=true"))
{ connection.Open();
// Use the connection
}
Visual Basic:
Using connection as new SqlConnection("context connection=true")
connection.Open() ' Use the connection
End Using
The context connection lets you execute Transact-SQL statements
in the same context (connection) that your code was invoked in the first place.

"HDR=Yes;" indicates that the first row contains columnnames, not data
"IMEX=1;" tells the driver to always read "intermixed"
data columns as text. Note that this option might affect excel sheet write access negative.
TIP! SQL syntax: "SELECT * FROM [sheet1$]" -
i.e. worksheet name followed by a "$" and wrapped in "[" "]" brackets.
TIP! Check out the [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel]
located registry REG_DWORD "TypeGuessRows". That's the key to n
ot letting Excel use only the first 8 rows to guess the columns data type.
Set this value to 0 to scan all rows. This might hurt performance.
