If we dont set the ConnectTimeout value, e.g. "Connect Timeout=60", (neither in SqlCommand), what's the dafault value it will be? I was told it's 15s
Thanks
The server default timeout for SQL server is 600 seconds.
If you use TrustServerCertificate=true (or its equivalent) in the connection string, the connection process skips the trust chain validation. In this case, the application connects even if the certificate can't be verified. Using TrustServerCertificate=false enforces certificate validation and is a best practice.
Using SQL Server Management StudioIn Object Explorer, right-click a server and select Properties. Click the Connections node. Under Remote server connections, in the Remote query timeout box, type or select a value from 0 through 2,147,483,647 to set the maximum number seconds for SQL Server to wait before timing out.
Connection Timeout specifies the time limit (in seconds), within which the connection to the specified server must be made, otherwise an exception is thrown i.e. It specifies how long you will allow your program to be held up while it establishes a database connection.
The default value is 15 seconds. The value set is less than 0. The following example creates a SqlConnection and sets the Connection Timeout to 30 seconds in the connection string. The code opens the connection and displays the ConnectionTimeout property in the console window.
If we dont set the ConnectTimeout value, e.g. "Connect Timeout=60", (neither in SqlCommand), what's the dafault value it will be? I was told it's 15s The default connection timeout in SqlClient is 15 seconds. The time (in seconds) to wait for a connection to open. The default value is 15 seconds. Your've been told correctly.
We can override the default connection timeout of 15 sec for sql server by setting Connect Timeout=30. Is it possible to set it value less than 15 sec, i tried setting it to Connect Timeout=1 but it doesn't taken the new value it took 15 sec.Thanks, Merli.
How I remember, Connection timeout is a time when server writing for connection if host unreachable. If you fill it by 0 and client will has connection problems server will close connection immidietly when clients connection losts Thanks for contributing an answer to Server Fault!
