Assembly: System.Data (in system.data.dll)
An exception occurred while executing the command against a locked row. This exception is not generated when you are using Microsoft .NET Framework version 1.0.
You can use the ExecuteNonQuery to perform catalog operations (for example, querying the structure of a database or creating database objects such as tables), or to change the data in a database without using a DataSet by executing UPDATE, INSERT, or DELETE statements.
Although the ExecuteNonQuery returns no rows, any output parameters or return values mapped to parameters are populated with data.
For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.
The following example creates a SqlCommand and then executes it using ExecuteNonQuery. The example is passed a string that is a Transact-SQL statement (such as UPDATE, INSERT, or DELETE) and a string to use to connect to the data source.
