Parameters

cmdSelectFinished: Type: LinkarClientOperationAsyncCallbackLkData
Return type in asynchronous methods
filename: Type: SystemString
File name. For example LK.ORDERS
selectClause (Optional): Type: SystemString
Fragment of the phrase that indicate the selection condition. For example WITH CUSTOMER = '1'
sortClause (Optional): Type: SystemString
Fragment of the phrase that indicates the selection order. If there is a selection rule, Linkar will execute a SSELECT, otherwise Linkar will execute a SELECT. For example BY CUSTOMER
dictClause (Optional): Type: SystemString
Is the list of dictionaries to read, separated by space. If dictionaries are not indicated the function will read the complete buffer. For example CUSTOMER DATE ITEM
preSelectClause (Optional): Type: SystemString
It's an optional statement that will execute before the main Select
selectOptions (Optional): Type: LinkarCommonSelectOptions
Object that defines the different reading options of the Function: calculated, dictionaries, conversion, formatSpec, originalRecords, onlyItemId, pagination, regPage, numPage.
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).
