ColumnValue Property

This is the actual data contained in the column.

Syntax

 sapclient.getColumnValue(index, [callback])
 sapclient.setColumnValue(index,  columnValue_Buffer, [callback])

Default Value

""

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getColumnValue([callback]) method is defined as:

function(err, buffer){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'buffer' is the value returned by the method.

The callback for the setColumnValue([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This is the actual data contained in the column.

The size of the array is controlled by the ColumnCount property.

This property is not available at design time.
