GetDeleteCommand(Boolean) Method

In This Topic

Gets the automatically generated SQL statement required to perform deletions on the data source when an application calls System.Data.Common.DbDataAdapter.Update() on the MagentoDataAdapter.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Shadows Function GetDeleteCommand( _
   ByVal useColumnsForParameterNames As Boolean _
) As MagentoCommand

public new MagentoCommand GetDeleteCommand( 
   bool useColumnsForParameterNames
)

Parameters

useColumnsForParameterNames: Determines whether names of parameters in command text will be based on columns' names.

Return Value

The text of the SQL statement to be executed.

Remarks

You can use the GetDeleteCommand method for informational or troubleshooting purposes because it returns the MagentoCommand object to be executed.

You can also use GetDeleteCommand as the basis of a modified command. For example, you might call GetDeleteCommand and modify the CommandTimeout value, and then explicitly set that on the MagentoDataAdapter.

After the SQL statement is first generated, you must explicitly call Devart.Common.DbCommandBuilderBase.RefreshSchema if it changes the statement in any way. Otherwise, the GetDeleteCommand still will be using information from the previous statement, which might not be correct. The SQL statements are first generated when the application calls either System.Data.Common.DbDataAdapter.Update(System.Data.DataSet) or GetDeleteCommand.

useColumnsForParameterNames argument determines whether names of parameters in command text will be like ":p1", ":p2" (if false), or names of columns will be used (if true), like ":mycolumn1", ":myothercolumn".
