Working with Table Data
Once you have created the Recordset object and connected to a table, you can use IDL DataMiner methods to retrieve and manipulate the data in several ways. For example, you can:
- find out if a table is "ReadOnly",
- get properties of the recordset,
- move the cursor,
- add records,
- delete records,
- retrieve fields,
- set fields,
- find the current row number in a recordset,
- find the number of fields in a recordset,
- get an array of field information structures, one for each field in the recordset.
You can also obtain information about a database or recordset concerning the following:
Moving Through a Recordset
Moving through recordsets is based on the concept of the cursor. The cursor is the current row, or record, in the recordset. When you refer to fields in a Recordset, you obtain values from the current record, and only the current record can be modified.
You can use the Recordset object's MoveCursor method to navigate through the records in a recordset. Keywords to the MoveCursor method allow you to specify new cursor locations.
In the following example, the MoveCursor method and FIRST keyword move to the first record.
In the following example, the MoveCursor method and NEXT keyword move to the next record.
