Rows.keysString()

note

This article is about the keysString() function of the Rows object.

Rows.keysString()

Gets the keys string of the first record in the Rows object. Unlike Rowset.keysString(), which identifies the parent keys of a row set, this identifies the record's own primary key.

Returns a string. Returns undefined if no record is available.

Syntax

$.udb( *ds* ).rows( [rowRef1], [rowRef2] ).keysString()
$.udb( *ds* ).rowSet( *rowSet* ).rows( [rowRef1], [rowRef2] ).keysString()

The required ds parameter is a data source selector.

The optional rowSet parameter is a rowset identifier. If the .rowSet() clause is omitted, then .rowSet('current') is assumed.

The optional rowRef1, rowRef2 are row selectors. If omitted, all records in scope are addressed.

Example

$.udb('EMP').rows('current').keysString();

Example result:
'$9:5'
