Files
| File in Delphi | Contains |
|---|---|
Ora_StoredProc.dprojOra_StoredProc.dpr | The project itself. |
fOra_StoredProc.pasfOra_StoredProc.fmx | The main form. |
Implementation
The sample implements the following features.
Create table adapter
|
1 2 3 4 5 6 |
var oAdapt: IFDDAptTableAdapter; <em>// ...</em> begin <em>// create table adapter</em> FDCreateInterface(IFDDAptTableAdapter, oAdapt); |
Assign command
|
1 2 3 4 5 6 7 8 |
var oComm: IFDPhysCommand; <em>// ...</em> begin <em>// ...</em> with oAdapt do begin FConnIntf.CreateCommand(oComm); SelectCommand := oComm; |
Set the DatSTable name
To set the DatSTable name where the rows are fetched, type the following:
|
1 |
DatSTableName := 'StoredProc'; |
Set up the SelectCommand property
The SelectCommand property is set up by setting the following properties:
- BaseObjectName to set the package name.
- CommandText to set the procedure name.
- Command Kind to set the kind of content of the CommandText property. It is set to stored procedure with cursor.
Once the parameters are set up, the sample calls the Prepare method.
|
1 2 3 4 5 6 7 8 9 |
with SelectCommand do begin <em>// set package name</em> BaseObjectName := 'FDQA_testpack'; <em>// set porcedure's name</em> CommandText := 'SelectShippers'; <em>// we have stored procedure with cursor</em> CommandKind := skStoredProcWithCrs; Prepare; end; |
Fetch rows
|
1 2 |
Define; Fetch; |
Uses
- FDCreateInterface
- IFDPhysCommand
- IFDPhysConnection
- Prepare
- The sample also uses some methods such as Define or Fetch of the following units:
- FireDAC.DApt.Intf
- FireDAC.DApt
