将每个表的Code附加到Name前面，格式为：原Code + 空格 + 原Name

Option Explicit
ValidationMode = True
InteractiveMode = im_Batch

Dim mdl ' the current model

' get the current active model
Set mdl = ActiveModel
If (mdl Is Nothing) Then
  MsgBox "There is no current Model"
ElseIf Not mdl.IsKindOf(PdPDM.cls_Model) Then
  MsgBox "The current model is not an Physical Data model."
Else
  ProcessFolder mdl
End If

Private Sub ProcessFolder(folder)
On Error Resume Next
  Dim tab ' running table
  For Each tab In folder.tables
    If Not tab.isShortcut Then
      ' 将Code附加到Name前
      tab.name = tab.code & " " & tab.name
    End If
  Next
  
  ' 递归处理子包
  Dim f ' running folder
  For Each f In folder.Packages
    If Not f.IsShortcut Then
      ProcessFolder f
    End If
  Next
End Sub

只导出数据，带insert和字段

sudo -u postgres pg_dump -U postgres -d $1 --column-inserts --data-only -t 表名1  -t 表名2   -f $2.sql

导入

#!/bin/bash
sudo -u postgres psql -U postgres -d $1 < $2

不区分大小写索引建立

drop index ems.sys_user_user_name;
create unique index   cclv_player_user_name     on ems.sys_user USING btree (LOWER(user_name));
