Returns the query result in a relational table format, 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. |
* filename |
string char*
|
|
File or table name defined in Linkar Schemas. Table notation is: MainTable[.MVTable[.SVTable]] |
selectClause
|
string char* |
|
fragment of the phrase that indicate the selection condition For example WITH CUSTOMER = '1'
|
sortClause
|
string char* |
|
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
|
string char* |
|
the list of dictionary definitions to be read, separated by a space. If dictionary IDs are not indicated the function will read the complete entire items. For example CUSTOMER DATE ITEM
|
tableOptions |
char*
|
null / Nothing NULL |
Object that defines options including pagination and LkData fields to return |
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.
TABLE output format uses the defined control characters in EntryPoints Parameters .Table Row Separator and Column Row Separator.
By default:
| • | TAB char(9) for columns. |
• VT char(11) for rows.
