我在 Application Engine 程序中有以下 PeopleCode 步骤,该程序使用文件布局读取 CSV 文件,然后将数据插入表中,我只是想更好地了解代码行 ( &SQL1 = CreateSQL("%Insert(:1)");
) 中的下面的脚本被生成。看起来 CreateSQL 在 Insert 语句中使用了绑定变量 (:1),但我正在努力寻找在程序中定义该变量的位置。
Function EditRecord(&REC As Record) Returns boolean;
Local integer &E;
&REC.ExecuteEdits(%Edit_Required + %Edit_DateRange + %Edit_YesNo + %Edit_OneZero);
If &REC.IsEditError Then
For &E = 1 To &REC.FieldCount
&MYFIELD = &REC.GetField(&E);
If &MYFIELD.EditError Then
&MSGNUM = &MYFIELD.MessageNumber;
&MSGSET = &MYFIELD.MessageSetNumber;
&LOGFILE.WriteLine("****Record:" | &REC.Name | ", Field:" | &MYFIELD.Name);
&LOGFILE.WriteLine("****" | MsgGet(&MSGSET, &MSGNUM, ""));
End-If;
End-For;
Return False;
Else
Return True;
End-If;
End-Function;
Function ImportSegment(&RS2 As Rowset, &RSParent As Rowset)
Local Rowset &RS1, &RSP;

&SQL1 = CreateSQL("%Insert(:1)");

&RecordName = "RECORD." | &RS2.DBRecordName;
&REC2 = CreateRecord(@(&RecordName));
&RECP = &RSParent(1).GetRecord(@(&RecordName));
For &I = 1 To &RS2.ActiveRowCount
&RS2(&I).GetRecord(1).CopyFieldsTo(&REC2);
If (EditRecord(&REC2)) Then
&SQL1.Execute(&REC2);
&RS2(&I).GetRecord(1).CopyFieldsTo(&RECP);
For &L = 1 To &RS2.GetRow(&I).ChildCount
&RS1 = &RS2.GetRow(&I).GetRowset(&L);
If (&RS1 <> Null) Then
&RSP = &RSParent.GetRow(1).GetRowset(&L);
ImportSegment(&RS1, &RSP);
End-If;
End-For;
If &RSParent.ActiveRowCount > 0 Then
&RSParent.DeleteRow(1);

&LOGFILE.WriteLine("****Correct error in this record and delete all error messages");
