All content below this line refers to {{#multireplace:Data.DB.TDataSet.PSGetCommandText|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
Gets the SQL command to be executed by PSExecute.
If the provider's Options property includes poAllowCommandText, clients can supply an SQL command along with a call to TCustomProvider.GetRecords or TCustomProvider.Execute. This command is passed to the dataset by a call to PSSetCommandText, and subsequently executed by a call to PSExecute.
This method is an implementation of the IProviderSupport.PSGetCommandText method and, by default, returns an empty string, because TDataSet does not implement a provider by default. To use it, every TDataSet descendant must override it in its specific way.
