VS. NET (C #) Database Interface: SqlCommand object asynchronous execution case code, vs.net When executing the Command object Command, you must wait until the Command is complete before other operations can be executed. For example, if you execute the ExcuteNonQuery () method, the application will remain blocked until the data operation is completed successfully, or the connection is terminated abnormally and times out. The idea of asynchronous exec

A few days ago, the previous SQL Execution operations were switched to the sqlhelper operation method. For convenience of debugging, the printing method of paramssql is customized. After Params is passed and executed, you can call the following method to print the Params and value values. SQL Params of sqlclient can be printed. Applog is a custom debugging class. You can switch to console. writeline/response. Write and other printing debugging methods. This makes it easy to understand the proced

1 God said, to connect to the database, so there is sqlconnection (database connection, Configure connection string, user name and password, etc.) 2 God said, to execute SQL statements. Therefore, SQL commands are directly translated into SQL commands. Each sqlcommand has commandtext and parameters text and parameters. Complete the command and execute it. Of course, make sure that the connection is open. Nothing can be done without connection. 3 God b

SqlconnectionIndicates an open connection to the SQL Server database. System. Data. sqlclient. sqlconnection The sqlconnection object indicates a unique session with the SQL server data source. For the Client/Server database system, it is equivalent to a network connection to the server. Sqlconnection is used with sqldataadapter and sqlcommand to improve performance when connecting to the Microsoft SQL Server database. For all third-party SQL Server

The SqlCommand class represents a Transact-SQL statement or stored procedure to be executed against a SQL Server database, with several attributes and several methods that can be found on MSDN using a variety of methods.Here are a few common thingsFirst, the attributeCommandText Gets or sets the Transact-SQL statement, table name, or stored procedure to be executed against the data source.CommandTimeout Gets or sets the wait time before terminating an

As as as MSDN documentation, IT is clearly mentioned this asp.net is supported on Win NT but dear Bill Gates fans just CH Eck out of this letter from Scott and would find that ASP.net isn't supported on NT for some technical reasons.

Connect Timeout: Currently, the common method for setting SOCKET connect timeout on each platform is to use select (). The specific method is as follows: 1. Establish socket; 2. Set the socket to non-blocking mode; 3. Call connect (); 4. Use select () to check whether the socket descriptor is writable; 5. Determine the connect () result based on the result returned by select; 6. set socket back to blocking

I encountered a query exception today. I checked it online and thanked the original author and the translator. If your database connection class is the data access application blocks "sqlhelper" or sqlclient class, you may encounter the following timeout exception when performing a very time-consuming SQL operation. --------------------------- ---------------------------Timeout expired. The

reason is that the connection timed out during the MSSQL operation. I did not pay attention to this issue before, probably because I set the connection time limit in the configuration file and found a solution online, most of them are solved in database connection strings.
