Session.ExecuteNonQuery(String, QueryParameterCollection) Method

Executes the specified SQL statement and returns the number of rows affected.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v24.2.dll

Declaration

C#

public int ExecuteNonQuery(
    string sql,
    QueryParameterCollection parameters
)

VB.NET

Public Function ExecuteNonQuery(
    sql As String,
    parameters As QueryParameterCollection
) As Integer

Parameters

Name	Type	Description
sql	String	Specifies an SQL statement.
parameters	QueryParameterCollection	Specifies query parameter values.

Returns

Type	Description
Int32	The number of rows affected by the executed SQL statement.

Remarks

Use the ExecuteNonQuery method to execute SQL statements that do not produce result sets, such as UPDATE, INSERT, and DELETE statements.

Use QueryParameterCollection to pass strongly-typed parameters. See examples here: Always Encrypted (SQL Server only).

The connection provider automatically generates sequential parameter names (p0, p1, p2 …). To specify custom parameter names, use the overloaded ExecuteNonQuery(String, String[], QueryParameterCollection) method.

To learn more about executing SQL statements in XPO, refer to Direct SQL Queries.

Note

The ExecuteNonQuery method sends statements directly, so the correct statement syntax and parameter names format depends on a particular database server.
