The SelectForUpdate Method

Calling selectForUpdate(true) on a record buffer replaces the use of the forupdate keyword in a select statement. The following piece of X++ code

custTable.selectForUpdate(true);
select custTable where custTable.AccountNum == '4000';




is equal in behavior to this code.

[View full width]
select forupdate custTable where custTable
.AccountNum == '4000';




Depending on the concurrency model settings on the table, a NOLOCK or UPDLOCK hint is added to the SELECT statement parsed to SQL Server 2000.

Tip

If you use the Query framework instead of select statements to retrieve records, it is also possible to retrieve these records as if a forupdate keyword had been used by calling update(true) on the QueryBuildDataSource object.
