Now you are ready to get the field values out of the record buffer and into some local variables.

In this example, we are making assumptions about which field is at which ordinal position within the table, as well as the size of the field.

The table used by this example is CUSTOMER.DB, included with the BDE SDK.

In general, it is recommended to use DbiGetFieldDescs to get information about a field before retrieving it. Also note that a single function, DbiGetField, is used to get all fields (other than BLOBs) from a table.

 

DFLOAT                custNum;

BOOL                                isBlank;

 

Chk(DbiGetField(

   hCur,                                          // Cursor which contains the record

   1,                                // Field Number of the "Customer" field.

   pRecBuf,                                        // Buffer containing the record

   (pBYTE)&custNum,                                // Variable for the Customer Number

   isBlank));                                                // Is the field blank?
