记录一个放在IBM Domino Notes 数据库视图上的字段值修改公式，已经从有点小BT升级到很有些BT了。

考虑了旧值的备份，简要表的读写，新旧值相等的忽视。

REM {修改字段值.v3	tmpFieldName=字段名称; tmpFieldValue=要赋给该字段的值.};
tmpProfile:="adm_oper_profile";
tmpFieldName:=@GetProfileField(tmpProfile; "lastOPFieldName";"admin") ;
tmpFieldValue:=@GetProfileField(tmpProfile; "lastOPFieldVal";"admin") ;

NL:=@NewLine;
tmpTimestamp:=@ReplaceSubstring(@Text(@Now);"-":":":" ";"":"":"_");
tmpTitle:="TimeStamp:"+tmpTimestamp+NL+NL;

tmpFieldName:=@Prompt([OkCancelEdit]; "Enter Field Name "; tmpTitle+"Type Field Name in the box below.";tmpFieldName);
tmpFieldValue:=@Prompt([OkCancelEdit]; "Enter Field Value"; tmpTitle+"Type Field Value in the box below."; tmpFieldValue);

@If(@GetField(tmpFieldName)=tmpFieldValue;
 @Return(@Prompt([Ok];"Error";"New Value == Old Value ! SKIP!"+NL+NL+tmpFieldValue));
"");

REM {backup old value};
tmpBakFN:="$bak_"+tmpFieldName;
tmpBakFV1:=@GetField(tmpBakFN);
tmpBakFV2a:="adm_op_time:"+tmpTimestamp;
tmpBakFV2:=tmpBakFV2a:@GetField(tmpFieldName);
tmpBakFV:=@If(tmpBakFV1="";tmpBakFV2;tmpBakFV1:tmpBakFV2);
@SetField(tmpBakFN;tmpBakFV);

REM {change field val};
@SetField(tmpFieldName;tmpFieldValue);

@SetProfileField(tmpProfile; "lastOPFieldName";tmpFieldName;"admin") ;
@SetProfileField(tmpProfile; "lastOPFieldVal";tmpFieldValue;"admin") ;
