Cols.isUpdatable()

note

This article is about the isUpdatable() function of the Cols object.

Cols.isUpdatable()

Detects whether the first column in scope may be updated.

Returns 'true', 'false', or 'ifNull'. A value of 'ifNull' means the column is only updatable while its current value is still empty (NULL). See DataSourceContainer.isUpdatable() for the corresponding data-source-wide setting, which this value is combined with.

Syntax

$.udb( *ds* ).cols( [columns] ).isUpdatable()

The required ds parameter is a data source selector.

The optional columns is a column selector. If omitted, all columns in scope are selected.

Example

let updatable = $.udb('EMP').cols('ADDRESS').isUpdatable();
