Linkar Clients 2.1.3

Execute, Execute_Text, ExecuteAsync, ExecuteAsync_Text

Allows execution of any command in the database, 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 ArrayList		Return type in asynchronous methods. For further information see ASYNCHRONOUS CALLS
* credentialsOptions	CredentialsOptions char*		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.
* statement	string char*		The command to execute in the database.
outputStringType	enum DataFormat.TYPE typedef uint8_t DataFormatTYPE;	DataFormat.TYPE.MV	Indicates in which format of data to be received : 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.

Asynchronous calls are not yet available for C-based Client libraries including C, JavaScript, PHP, and Python.
