Returns an integer indicating the status of the specified parameter. Not available at design time and read-only at run time.
parameter_status = oraparameter.Statusparameter_status = oraparamarray.Status
Integer
The Status property is interpreted as a series of bits, each providing information about the parameter. Parameters can be bound only if they are enabled, and can be enabled only if they are auto-enabled.
The parameter Status property bit values are:
| Constant | Value | Description | 
|---|---|---|
| ORAPSTAT_INPUT | &H1& | Parameter can be used for input. | 
| ORAPSTAT_OUTPUT | &H2& | Parameter can be used for output. | 
| ORAPSTAT_AUTOENABLE | &H4& | Parameter is AutoBindEnabled. | 
| ORAPSTAT_ENABLE | &H8& | Parameter is Enabled. This bit is always set. | 
These values are located in the ORACLE_BASE\\ORACLE_HOME\oo4o\oraconst.txt file.
This example demonstrates the use of parameters and the ExecuteSQL method to call a stored procedure (located in ORAEXAMP.SQL). After calling the stored procedure, the Status property of each parameter is checked. Copy and paste this code into the definition section of a form. Then, press F5.
