前言

SysDictField 和 SysDictTable 用于訪問表和字段的元數據信息。

---

一、示例

循環表，使對應數據源的字段禁止編輯

public void fieldNoAllowEdit(Common    _common,formDataSource fds,boolean aE = false){TableId                 tableId;FieldId                 fieldId,extFieldId;SysDictTable            dictTable;SysDictField            dictField;int                     i, j;boolean                 ret = false;str                     fieldName;dictTable       = new SysDictTable(_common.tableId);for (i = 1; i <= dictTable.fieldCnt(); i++){fieldId     = dictTable.fieldCnt2Id(i);dictField   = new SysDictField(_common.tableId, fieldId);fieldName   = dictField.name();if (!dictField.isSystem() && (fieldName != 'fieldName1')){fds.object(fieldId).allowEdit(aE);}}}

判斷兩張相同表的字段值是否不同

public static boolean isDifference(Common    _common1, Common    _common2){TableId                 tableId;FieldId                 fieldId,extFieldId;SysDictTable            dictTable;SysDictField            dictField;int                     i, j;boolean                 ret = false;str                     fieldName;dictTable       = new SysDictTable(_common1.tableId);for (i = 1; i <= dictTable.fieldCnt(); i++){fieldId     = dictTable.fieldCnt2Id(i);dictField   = new SysDictField(_common1.tableId, fieldId);fieldName   = dictField.name();if (!dictField.isSystem() && (fieldName != 'PushState' && fieldName != 'PushDateTime'&& fieldName != 'Remark' && fieldName != 'CreateDateTime')){for (j = 1; j <= dictField.arraySize(); j++){extFieldId = fieldId2Ext(fieldId, j);if (_common1.(extFieldId) != _common2.(extFieldId)){ret = true;return ret;}}}}return ret;}
