VoDbRelation Function

Return the linking expression of a specified relation.

Namespace: XSharp.RT
Assembly: XSharp.RT (in XSharp.RT.dll) Version: 2.19

Syntax

Copy

 FUNCTION VoDbRelation(
	wRelation AS DWORD,
	pszRelation REF STRING
) AS LOGIC

public static bool VoDbRelation(
	uint wRelation,
	ref string pszRelation
)

Request Example View Source

Parameters

wRelation: Type: DWord
The position of the desired relation in the list of current work area relations.
The relations are numbered according to the order in which they were defined with SET RELATION.
pszRelation: Type: String
The position of the desired relation in the list of current work area relations.
The relations are numbered according to the order in which they were defined with SET RELATION.

Return Value

Type: Logic
The linking expression defined to wRelation.
If there is no relation set for wRelation, VODBRelation() returns a NULL_STRING.
TRUE if successful; otherwise, FALSE.

Remarks

VODBSetRelation() is similar to DBRelation(). This function, however, does not call the error handler and will not, therefore, produce a runtime error message or create an error object if it fails. Thus, it may be important to check the return value to determine if the function succeeded.
the LastRddError property in the runtime state. will contain needed information regarding any error that occurs.
See DbRelation(Usual) for more information
