Snapshot Sample

Previous pageReturn to chapter overviewNext page

This example creates a new snapshot-type Recordset object and opens it, appending it to the Recordsets collection in the default database. It then finds a record and prints it.

 

FUNCTION Start

LOCAL dbeng        AS DaoDBEngine

LOCAL db        AS DaoDatabase

LOCAL rstTitles        AS DaoRecordset

Set color TO w+/b

cls

// Open the database.

dbEng := DaoDbEngine{}

db := dbEng:OpenDatabase("\vo2jet\Northwind.mdb",NIL,NIL,NIL)

 

// Open a recordset on Titles table.

rstTitles := db:OpenRecordset("Titles", dbOpenSnapshot,NIL,NIL)

IF rstTitles:RecordCount > 0

   rstTitles:FindFirst("Title Like '*Computer*'")  // Any title on computers

   DO WHILE .not. rstTitles:NoMatch

       ? rstTitles:Fields:[Item,"Title"]:Value

       rstTitles:FindNext("Title Like '*Computer*'")

   ENDDO

 ?

 ? "And now in reversed order"

 ?

   rstTitles:FindLast("Title Like '*Computer*'")  // Any title on computers

   DO WHILE .not. rstTitles:NoMatch

       ? rstTitles:Fields:[Item,"Title"]:Value

       rstTitles:FindPrevious("Title Like '*Computer*'")

   ENDDO

 

ELSE

 

? "No such title"

ENDIF

 

db:Close()
