-> string

Parameters

filename: Type: SystemString
File name to read.
recordIds: Type: SystemString
It's the records codes list to read, separated by the Record Separator character (30).
dictClause (Optional): Type: SystemString
List of dictionaries to read, separated by space. If dictionaries are not indicated the function will read the complete buffer.
readOptions (Optional): Type: LinkarCommonReadOptions
Object that defines the different reading options of the Function: Calculated, dictClause, conversion, formatSpec, originalRecords.
outputStringType (Optional): Type: LinkarCommonDATAFORMATCRU_TYPE
Indicates in what format you want to receive the data resulting from the Read, New, Update and Select operations: MV, XML, XML_DICT, XML_SCH, JSON, JSON_DICT or JSON_SCH.
customVars (Optional): Type: SystemString
It's a free text that will travel until the database to make the admin being able to manage additional behaviours in the standard routine SUB.LK.MAIN.CONTROL.CUSTOM. This routine will be called if the argument has content.
receiveTimeout (Optional): Type: SystemInt32
It's the maximum time in seconds that the client will keep waiting the answer by the server. By default -1 (wait indefinitely).

Return Value

Type: String
Returns an object of type LkString with the results of the operation.

Exceptions
