ReadPrev Method

Read the previous row (record) from the table.

Syntax

public DBResponse ReadPrev( 
   out string dataArea
)

Parameters

dataArea: The returned data area.

Return Value

Returns a value indicating the status of the call.

Remarks

The previous available row is returned. A previous Read(String,Int32,String) or ReadFirst method call will determine the index used. If no previous table access has been performed, the primary index will be used.

Example

string itemRecord;
Int32 chan;
Symphony.dB.DBAccess itemAccess = new DBAccess("ITEM", "DATABASE:DatabaseManager");
if (itemAccess.OpenInput(out chan) == DBResponse.DBOK)
{
    //read the last row from the table
    itemAccess.ReadLast(0, out itemRecord);
    while (itemAccess.ReadNext(out itemRecord) == DBResponse.DBOK)
    {

    }
}
