Rowset.rows()

Gets a specified subset of records from the row set.

Returns a collection of records.

Syntax

row-set.rows( index, index )
row-set.rows( keyword, indicator )

Parameters are optional. If you do not pass any parameter, all records in the row set are addressed.

Parameters may be used to address specific records. You either pass one or two index parameters or you pass a keyword parameter that possibly requires an indicator parameter.

Passing index parameters

Index values are integers or arrays used to identify records in the data source:

• If you pass a single integer value, the record that corresponds to that index value is addressed.
• If you pass two integer values, the records corresponding to the first and the second index value are adressed and also all the records in between.
• If you pass an array of integer values, the records corresponding to the elements in the array are adressed.

Examples

To get the 5th record:

$.udb('EMP').rowSet('current').rows(4);

To get records 5, 6, 7, 8, 9 and 10:

$.udb('EMP').rowSet('current').rows(4, 9);

To get an array of indices:

$.udb('EMP').rowSet('current').rows([0, 1, 4, 7]); // rows with indices 0, 1, 4, and 7

Passing keyword and indicator values

Each keyword value is a string that identifies a predefined option. If the Indicator column is empty, it does not apply; otherwise, the indicator stated is required.

Examples

To get the records of a dataset:

$.udb('EMP').rowSet('current').rows('dataset'); // current dataset

$.udb('EMP').rowSet('current').rows('dataset', 2); // dataset 2

To get records that satisfy the equality condition EMPNO = 10:

$.udb('EMP').rowSet('current').rows( { EMPNO: "10" } );

To get records that satisfy more complex conditions:

$.udb('EMP').rowSet('current').rows( 'condition', { BIRTH_DATE: ">=01-JAN-1980" } );

$.udb('EMP').rowSet('current').rows( 'condition', { BIRTH_DATE: ">=01-JAN-1980&<=01-JAN-2000" } );

To get records where MANAGER is NULL and SALARY is higher than 35000:

$.udb('EMP').rowSet('current').rows( 'condition', { MANAGER: "NULL", SALARY: ">35000" } );

To get a record by row ID:

$.udb('EMP').rowSet('current').rows('id', 15); // row with id '15'
