Hi,

Is it possible to work with the Sqlite database via FWH ?

Hello James---
See this code.

Code: Select all  Expand view  RUN

oConG := OpenSQLite( oConG )

cCad := "SELECT * FROM DOCUMENTO"
oObj := SSQLQry( oConG, oObj, cCad )

IF oObj:RecordCount() =0
  cCad := "INSERT INTO DOCUMENTO (NUM_RUC, TIP_DOCU, NUM_DOCU) VALUES ('00000000000','','')"
  lOK := oConG:Execute( cCad )
EndIf

cCad := "UPDATE PARAMETRO SET val_para = '1' WHERE cod_para = 'TIMEENVIA'"
lOK := oConG:Execute( cCad )



//---------------------------------------------------------------------------------------------------------------
Function OpenSQLite( oConL )
oConL                  := TOleAuto():new( "adodb.connection" )
oConL:ConnectionString := "Data Source=archivosfs;Version=3;New=True;Compress=True;"

TRY
   oConL:Open()
CATCH
   MsgStop( "No Hay Conexion ODBC - SQLIte", "Error", 2 )
   oConL := Nil
   QUIT
   QUIT
END

SysRefresh()

Return( oConL )

oRs1 := FW_OpenRecordSet( oConT, cCon )
Return( oRs1 )
