Sql-server – Store session (asp.net) in SQL Server

asp.netsql server

If we want to store sessions in SQL Server, which table stores the sessions?

To implement ASP.NET SQL Server mode session state management, you must modify the element of your application's Web.config file as follows:

1.Set the mode attribute of the element to SQLServer to indicate that session state is stored in SQL Server.

2.Set the sqlConnectionString attribute to specify the connection string for SQL Server. For example:

  sqlConnectionString="data source=MySQLServer;user id=<username>;password=<strongpassword>"

Note The user, , must have permissions to perform this operation on the database.

The modified element should appear as follows:

        <sessionState 
        mode="SQLServer"
        sqlConnectionString="data source=127.0.0.1;user id=<username>;password=<strongpassword>"
        cookieless="false" 
        timeout="20" 
/>

The question is that is there a particular table storing the sessions?

Store session in SQL Server is a vague concept.

Thanks.

You're supposed to run the ASP.Net SQL Server Registration Tool first. The tool will create the appropriate session state tables.

Syntax:

ALTER TABLE {TABLENAME} 
ADD {COLUMNNAME} {TYPE} {NULL|NOT NULL} 
CONSTRAINT {CONSTRAINT_NAME} DEFAULT {DEFAULT_VALUE}
WITH VALUES

Example:

ALTER TABLE SomeTable
        ADD SomeCol Bit NULL --Or NOT NULL.
 CONSTRAINT D_SomeTable_SomeCol --When Omitted a Default-Constraint Name is autogenerated.
    DEFAULT (0)--Optional Default-Constraint.
WITH VALUES --Add if Column is Nullable and you want the Default Value for Existing Records.

Notes:

Optional Constraint Name:
If you leave out CONSTRAINT D_SomeTable_SomeCol then SQL Server will autogenerate
a Default-Contraint with a funny Name like: DF__SomeTa__SomeC__4FB7FEF6

Optional With-Values Statement:
The WITH VALUES is only needed when your Column is Nullable
and you want the Default Value used for Existing Records.
If your Column is NOT NULL, then it will automatically use the Default Value
for all Existing Records, whether you specify WITH VALUES or not.

How Inserts work with a Default-Constraint:
If you insert a Record into SomeTable and do not Specify SomeCol's value, then it will Default to 0.
If you insert a Record and Specify SomeCol's value as NULL (and your column allows nulls),
then the Default-Constraint will not be used and NULL will be inserted as the Value.

Notes were based on everyone's great feedback below.
