TSQLQuery.DataSource property

Declaration

property DataSource:;

Description

Datasource can be set to a dataset which will be used to retrieve values for the parameters if they were not explicitly specified.

When Open or ExecSQL is called, and the Datasource property is not Nil then for each parameter for which no value was explicitly set (its Bound property is False), the value will be retrieved from the dataset connected to the datasource.

For each parameter, a field with the same name will be searched, and its value and type will be copied to the (unbound) parameter. The parameter remains unbound.
