Get_Field_Value command

Include: Use Db\DBCommands.pkg

Purpose

Reads a field value from a DD local buffer into a variable.

Syntax

Get_Field_Value oDataDictionary field to variable
Get_Field_Value oDataDictionary field to variable Length iLength
Get_Field_Value oDataDictionary field to variable Length iLength Offset iOffset

How it works

  • Four-argument form gets Field_Current_Value.
  • Length forms get Field_Current_Value_Mid; when no offset is supplied, offset 0 is used.
  • The field argument is a DD field reference such as (RefTable(oCustomerDD.Name)).

Example

String sName

Get_Field_Value oCustomerDD (RefTable(oCustomerDD.Name)) to sName
