The DbProviderServices implementation for the SqlClient provider for SQL Server.
Note that instance of this type also resolve additional provider services for Microsoft SQL Server
when this type is registered as an EF provider either using an entry in the application's config file
or through code-based registration in .
The services resolved are:
Requests for are resolved to a Singleton instance of
to create connections to SQL Express by default.
Requests for for the invariant name "System.Data.SqlClient"
for any server name are resolved to a delegate that returns a
to provide a non-retrying policy for SQL Server.

resolved to instances to provide default Migrations SQL
generation for SQL Server.
Requests for for the invariant name "System.Data.SqlClient" are

parameter and targeted for the version of the database corresponding to the provider manifest token.

A DDL script that creates schema objects based on the contents of the StoreItemCollection parameter
and targeted for the version of the database corresponding to the provider manifest token.
Create the database and the database objects.
If initial catalog is not specified, but AttachDBFilename is specified, we generate a random database name based on the AttachDBFilename.
Note: this causes pollution of the db, as when the connection string is later used, the mdf will get attached under a different name.
However if we try to replicate the name under which it would be attached, the following scenario would fail:
The file does not exist, but registered with database.
The user calls: If (DatabaseExists) DeleteDatabase
CreateDatabase
For further details on the behavior when AttachDBFilename is specified see Dev10# 188936
Connection to a non-existent database that needs to be created and populated with the store objects indicated with the storeItemCollection parameter.
Execution timeout for any commands needed to create the database.
The collection of all store items based on which the script should be created.
Determines whether the database for the given connection exists.
There are three cases:
1. Initial Catalog = X, AttachDBFilename = null: (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0
2. Initial Catalog = X, AttachDBFilename = F: if (SELECT Count(*) FROM sys.databases WHERE [name]= X) > true,
if not, try to open the connection and then return (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0
3. Initial Catalog = null, AttachDBFilename = F: Try to open the connection. If that succeeds the result is true, otherwise
if the there are no databases corresponding to the given file return false, otherwise throw.
Note: We open the connection to cover the scenario when the mdf exists, but is not attached.
Given that opening the connection would auto-attach it, it would not be appropriate to return false in this case.
Also note that checking for the existence of the file does not work for a remote server. (Dev11 #290487)
For further details on the behavior when AttachDBFilename is specified see Dev10# 188936
Connection to a database whose existence is checked by this method.
Execution timeout for any commands needed to determine the existence of the database.
The collection of all store items from the model. This parameter is no longer used for determining database existence.

Determines whether the database for the given connection exists.

2. Initial Catalog = X, AttachDBFilename = F: if (SELECT Count(*) FROM sys.databases WHERE [name]= X) > true,
if not, try to open the connection and then return (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0
3. Initial Catalog = null, AttachDBFilename = F: Try to open the connection. If that succeeds the result is true, otherwise
if the there are no databases corresponding to the given file return false, otherwise throw.

Connection to a database whose existence is checked by this method.
Execution timeout for any commands needed to determine the existence of the database.
The collection of all store items from the model. This parameter is no longer used for determining database existence.
True if the provider can deduce the database only based on the connection.
Delete the database for the given connection.
There are three cases:
1. If Initial Catalog is specified (X) drop database X
2. Else if AttachDBFilename is specified (F) drop all the databases corresponding to F
if none throw
3. If niether the catalog not the file name is specified - throw
Note that directly deleting the files does not work for a remote server. However, even for not attached
databases the current logic would work assuming the user does: if (DatabaseExists) DeleteDatabase
Connection
Timeout for internal commands.
Item Collection.

Set this flag to false to prevent values from being truncated to
the scale (number of decimal places) defined for the column. The default value is true,
indicating that decimal values will be truncated, in order to prevent breaking existing
applications that depend on this behavior.
With this flag set to true objects are created with their Scale
properties set. When this flag is set to false then the Scale properties are not set, meaning
that the truncation behavior of SqlParameter is avoided.
