Description
Indicates the number of datasets associated with the connection component.
Use DataSetCount to determine the number of datasets listed by the DataSets property. Depending on the TCustomConnection descendant, DataSets may include only the active datasets that use the connection component (as is the case with TDatabase and TSQLConnection), or it may list all datasets, regardless of whether they are active (as is the case with TADODatabase and DataSnap connection components TSOAPConnection). If DataSets includes only active datasets, the value of DataSetCount changes when datasets are opened and closed.
Use DataSetCount as an upper bound when iterating through the DataSets property.
