OleDbCommandBuilder.GetInsertCommand Method

  • Reference

Definition

Namespace:
System.Data.OleDb
Assembly:
System.Data.OleDb.dll
Assembly:
System.Data.dll
Package:
System.Data.OleDb v9.0.0

Gets the automatically generated OleDbCommand object required to perform insertions at the data source.

Overloads

GetInsertCommand()

Gets the automatically generated OleDbCommand object required to perform insertions at the data source.
GetInsertCommand(Boolean)

Gets the automatically generated OleDbCommand object required to perform insertions at the data source.

Remarks

An application can use the GetInsertCommand method for informational or troubleshooting purposes because it returns the text of the OleDbCommand object to be executed.

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

After the SQL statement is first generated, the application must explicitly call RefreshSchema if it changes the statement in any way. Otherwise, the GetInsertCommand will be still be using information from the previous statement, which might not be correct. The SQL statements are first generated when the application calls either UpdateCommand or GetInsertCommand.

public:
 System::Data::OleDb::OleDbCommand ^ GetInsertCommand(bool useColumnsForParameterNames);
public System.Data.OleDb.OleDbCommand GetInsertCommand (bool useColumnsForParameterNames);

Public Function GetInsertCommand (useColumnsForParameterNames As Boolean) As OleDbCommand

Parameters

If true, generate parameter names matching column names, if it is possible. If false, generate @p1, @p2, and so on.

Returns

OleDbCommand

The default behavior, when generating parameter names, is to use @p1, @p2, and so on for the various parameters. Passing true for the useColumnsForParameterNames parameter lets you force the OleDbCommandBuilder to generate parameters based on the column names instead. This succeeds only if the following conditions are met:
