Deletes one or more records of a file, synchronously or asynchronously.
* hasError (only C) |
BOOL* |
|
Only in C functions: bool pointer used in the C functions that indicates the return of the function is a system error and must be communicated to the Linkar SERVER
|
* callback
|
OperationAsyncCallbackString OperationAsyncCallbackLkData OperationAsyncCallbackClass ArrayList
|
|
Return type in asynchronous methods. For further information see ASYNCHRONOUS CALLS |
* credentialsOptions |
|
|
Object that defines the necessary data to access the database: Username, Password, EntryPoint, Language, FreeText. In the C Direct Functions, it is a char* |
* connectionInfo (only C) |
char* |
|
Only in C Persistent Functions: string that is returned by the Login function and contains all the necessary connection data. This data is necessary in persistent functions.
|
* [DICT] filename |
string char*
|
|
File name containing the records to be deleted. Append "DICT" if records are in a dictionary.
|
* recordIds |
string char*
|
|
The list of record keys, separated by the Record Separator character (30) : LinkarCommon.ASCII_Chars.RS. |
originalRecords |
string char*
|
|
Original records for Optimistic Lock verification, separated by the Record Separator character (30) : LinkarCommon.ASCII_Chars.RS.
|
deleteOptions |
char*
|
null Nothing
|
Object of type DeleteOptions provides details about how the delete operation(s) will be done. |
outputStringType |
enum DataFormat.TYPE typedef uint8_t DataFormatTYPE;
|
DataFormat.TYPE.MV
|
Format of the data received in response to delete operations : MV, XML or JSON. |
customVars |
string char* |
|
This is a free text field to send in the transaction. If not empty, subroutine SUB.LK.MAIN.CONTROL.CUSTOM will be called. Add custom code to that subroutine to define special behaviours for some or all transactions. |
receiveTimeout |
Numeric
|
-1 0
|
This is the maximum time in seconds that the client will wait for a response. Use 0 for no timeout. This is a function-specific override : -1 in a Persistent function defaults back to the timeout defined in the LinkarClt constructor. |
This function can generate exceptions.
In COM assemblies, a return value of type String will contain an error message if an error occurs when performing the operation.
