However, spaces within a string literal keyword or value are preserved. Any leading or trailing spaces around integer, Boolean, or enumerated values are ignored, even if enclosed in quotation marks. To include preceding or trailing spaces in the string value, the value must be enclosed in either single quotation marks or double quotation marks. If the value contains both single-quote and double-quote characters, the quotation mark character used to enclose the value must be doubled every time it occurs within the value.
Conversely, the double quotation mark can be used if the value starts with a single quotation mark. The single quotation mark is also useful if the value starts with a double-quote character. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks. To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. The equal sign (=) connects each keyword and its value.
ASP NET SQL SERVER CONNECTION STRING SERIES
The basic format of a connection string includes a series of keyword/value pairs separated by semicolons. Other errors can be found only when an attempt is made to open the connection. If errors in syntax are found when parsing, a runtime exception, such as ArgumentException, is generated. The connection string is parsed immediately after being set. For example, if you set a connection string that includes "Database= AdventureWorks", and then reset the connection string to "Data Source=myserver Integrated Security=true", the Database property is no longer set to "AdventureWorks".
Resetting the ConnectionString on a closed connection resets all connection string values (and related properties) including the password. If a server name is not specified, a connection will be attempted to the default instance on the local computer. To connect to a local computer, specify "(local)" for the server. SqlConnection properties return only those settings that are contained in the ConnectionString. In this case, none of the properties are updated. When the connection string is set, these properties are updated, except when an error is detected. Many of the connection string values have corresponding read-only properties. The ConnectionString property can be set only when the connection is closed. For more information, see Connection String Builders. Use the new SqlConnectionStringBuilder to construct valid connection strings at run time. "Persist Security Info=False Integrated Security=true Initial Catalog=Northwind server=(local)" The following example illustrates a typical connection string. You can use the ConnectionString property to connect to a database.
ASP NET SQL SERVER CONNECTION STRING PASSWORD
NET Framework Data Provider for SQL Server does not persist or return the password in a connection string unless you set Persist Security Info to true. Unlike OLE DB or ADO, the connection string that is returned is the same as the user-set ConnectionString, minus security information if the Persist Security Info value is set to false (default). The ConnectionString is similar to an OLE DB connection string, but is not identical. Return "Data Source=MSSQL1 Database=AdventureWorks " _ ' you can retrieve it from a configuration file. ' To avoid storing the connection string in your code, Private Function GetConnectionString() As String Virtual property System::String ^ ConnectionString ", _ NET Framework Version:9 ASP.NET Version.Gets or sets the string used to open a SQL Server database. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Please review the stack trace for more information about the error and where it originated in the code.Įxception Details: : A potentially dangerous Request.Path value was detected from the client (<).Īn unhandled exception was generated during the execution of the current web request.
