Library: Database access (OMDB legacy) Include: omdb.xin

Declaration

define external  function dbRecordMove
       read-only dbField  record

Argument definitions

record

is a dbField shelf bound to a record set created by an SQL query

Use dbRecordMove to change the position of the data cursor within the specified record set.

Requirements

You must include the following line at the beginning of your OmniMark program:

  include "omdb.xin"

The database connection represented by dbDatabase must be

• open (else external exception OMDB209).
• in scope (else external exception OMDB103).

The dbField shelf must be associated with a query (else external exception OMDB302).

The dbField shelf record must exist.

Usage Notes

The data cursor points to the currently active row of the record set. The cursor advances to the next row of the record set.

You can move the data cursor beyond the record set boundaries. However, if you attempt to retrieve a field value in this situation, external exception OMDB205 will be thrown. Hint: Before attempting to retrieve field values, you should use the dbRecordExists function to verify that the data cursor is within the record set boundaries.

What sort of cursor movement is possible depends on the database and database interface being used. If using the OCI8 or OCI8i interface, you can only advance to the next record. Some ODBC drivers allow additional flexibility.

Example

        repeat
           exit unless dbRecordExists my-query
  
           repeat over my-query
              output dbFieldValue my-query null '-DNF-'
              output '%t' when ! #last
           again
           output '%n'
  
           dbRecordMove my-query
         again
