ExecuteNonQuery Method (DbCommandBase)

In This Topic

Executes SQL statement against the Devart.Common.DbCommand.Connection and returns the number of rows affected.

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Function ExecuteNonQuery() As Integer

public override int ExecuteNonQuery()

Return Value

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.

Remarks

You can use ExecuteNonQuery method 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 ExecuteNonQuery does not return any rows, any output parameters or return values mapped to parameters are populated with data.

When executing stored procedures you have to create Devart.Common.DbParameter with Devart.Common.DbParameter.Direction set to ReturnValue or set ParameterCheck property to true.
