If the database connection (java.sql.Connection) is in a waiting state for wait_timeout seconds, MYSQL5 closes the connection. At this point, your Java app's connection pool still legitimately holds a reference to that connection. This error is encountered when the connection is used for database operations. This explains why my program cannot log on th

made me Very depressed.Then on the Internet various search, finally find the crux of the problem, or the pit dad IIS out of things. When IIS connects to a connection that you think is a trust connection, it automatically assigns an account running process, but this account is not necessarily your Windows login account, which means that there is no access to the database, and then it is tragic.The current solution is also I think the simplest is not to use trust connection, in the connection str

there is character data. Here we understand why the first behavior of the character type is guaranteed. You can force a column's data type to be set to a character type, so what type of data appears in the column is not afraid. The job you need to do is to reset the field name and delete the first record after you've finished getting the data. The code is as follows:View Source print? 01.DataTable dt = new DataTable ();02.03.using (OleDbCommand cmd = new OleDbCommand ()) {04. cmd. Connection =

logical collection of members, and the order of the members is irrelevant. A query that sorts a table can return an object that contains rows organized in a specific physical order. ANSI calls this object a cursor. Understanding this step is the basis for a proper understanding of SQL. Because this step does not return a table (instead of returning a cursor), a query that uses the ORDER BY clause cannot be used as a table expression. Table expressions include: views, inline table-valued functio
