Steps A 1: on the document design interface, increase a field: the person approving, audit state packet filter as document, and the data message of described document status field added in the document metadata table that presets, described document metadata table is used to write down the identification parameter of document mode field;
With reference to shown in Figure 3, show the synoptic diagram of a document design interface in the object lesson of the present invention, if the person approving's field on the document design interface has value, represent that then this list examines, otherwise this singly is in the state of audit;
Need to prove, described document metadata table not only can be used to write down the identification parameter of document mode field, can also be used to write down the transaction types of document, perhaps other attributive character of document status field, for example, the title of document status field is described, in the present example, and shown in second row of described document metadata table in can following Table I CClassTableInfo:
| FClassTypeID | FCaption_CHS | FFieldName | FTableName | | FSRCTableName | FConditionExt | |
| 200000000 | The person approving | FChecker | t_BOS200000000 | FUserID | t_User | 1000000 | |
| 200000000 | Check and write off | FWriteOf | t_BOS200000000 | 1000001 | |||
| 200000000 | Keep accounts | FAccount | t_BOS200000000 | 1000002 | |||
| 200000000 | Close | FClose | t_BOS200000000 | 1000003 | |||
| 1007109 | Sell | FSalesMethod | t_BOS200000000 | 1000006 |
Wherein, field and the data declaration among the last Table I CClassTableInfo is as follows:
FClassTypeID: described FClassTypeID represents the transaction types of document, and this field value is a bill type, and for example, the transaction types of import order is: 1007100; The transaction types of sales order is 1007109, or the like; The second row field value is that 200000000 meaning is in the last table: person approving's field is that to belong to transaction types be 200000000 document;
FCaption_CHS: described field FCaption_CHS is that the title of document filtered fields under simplified environment described, for example, and " person approving ", " checking and writing off " etc.;
FFieldName: which field is the concrete data that described field FFieldName is used to identify the document filtered fields be kept at;
FTableName: which table is the concrete data that described field FTableName is used to identify the document filtered fields be kept at; For example, last table the second capable in content implication in FFieldName and the FTableName field be: the data of person approving's field are kept among the field FChecker of table t_BOS200000000;
FSRCFieldName: described field FSRCFieldName is used to identify the Data Source of document filtered fields; The implication of this field was during last table the second was capable: the Data Source of person approving's field is the FUserID field among the table t_User;
FConditionExt: described field FConditionExt is the identification parameter of document status field, can identify the pairing filtration state ID of this field, and described identification parameter is corresponding with the field FID that the document that presets filters in the state table;
Be understandable that, also can increase other document status in the table, as above the closed condition shown in the table, check and write off state, record keeping state or marketing method etc.;
Need to prove, when newly-increased document filters the data message of state in the described document metadata table, also filter the corresponding states of inserting person approving's field in the state table simultaneously to described document, described document filters state table and is used to write down the filtration status information corresponding with described identification parameter, and described document metadata table is related by described identification parameter with document filtration state table;
In practice, described document filter state table can following Table I CClassCondition shown in:
| FID | FName_CHS | FDataSource_CHS |
| 1000000 | The audit state | All; None ~ examine; Isnull (@Field, 0)＞0 ~ not audit; Isnull (@Field, 0)＜=0 |
| 1000001 | Check and write off state | All; None ~ do not check and write off; Isnull (, 0)=0 ~ check and write off fully; Isnull (@Field, 0)=1 ~ partly check and write off; Isnull (@Field, 0)=2 |
| 1000002 | Account status, for example | Do not do account; Isnull (@Field, 0)＜=0 ~ does account; Isnull (@Field, 0)＞0 ~ all; None |
| 1000003 | Closed condition | Do not close; @Field＜2 ~ close; @Field=2 ~ all; None |
| 1000006 | Marketing method | Sell on credit; Isnull (@Field, 0)=101 ~ cash sale; Isnull (@Field, 0)=100 ~ instalment sale; Isnull (@Field, 0)=102 ~ entrust and sell on a commission basis; Isnull (@Field, 0)=103 ~ directly transportation and sales are sold; Isnull (@Field, 0)=20296 ~ be commissioned and sell on a commission basis; Isnull (@Field, 0)=20297 ~ retail; Isnull (@Field, 0)=20298 ~ all; None |
In the present example, what be applied to is the data in last Table I CClassCondition second row, as follows to wherein explanation of field:
FID: the content of described field FID is the identification parameter that described document filters state, and not described document filters the unique identification of state;
FName_CHS: the title that the described document of the content representation of described field FName_CHS filters state, in the present example, described name is called the audit state;
FDataSource_CHS: the content of described field FDataSource_CHS is the filtration Status Type of document, and in the present example, the audit of document has three kinds of states: examined all, and not audit; Isnull (, 0)＞0th wherein, the metadata of described filtration Status Type is expressed formula;
Steps A 2: from the document metadata table that presets, obtain the identification parameter of described document status field;

After adding to described filtration Status Type on the document filtering interface, the user can select document status on described document filtering interface, and in the present example, with reference to figure 4, user-selected document status is " examining ";
Steps A 6: as filtercondition, document to be filtered is filtered with described filtration Status Type metadata corresponding expression formula;
Preferably, the realization of this step can comprise following substep:
Substep A61: the metadata that reads described filtration Status Type is expressed formula;
After the user has selected the document status of " examining ", click [determining] button, then read described " examining " corresponding metadata expression formula isnull (, 0)＞0;
Substep A62: replace the conditional-variable in the described metadata expression formula, generate peek SQL;
Replace Bian Liang @Field with the field FChecker among the table t_BOS200000000, peek SQL just is:
select*from_t BOS200000000 where isnull(FChecker，0)＞0；
Substep A63: document to be filtered is filtered according to described peek SQL;
Obtain peeking behind the SQL, obtaining person approving's field according to described peek SQL from database is not the data of empty (being that person approving's field has value), thereby the document that will examine from document to be filtered filters out;
Steps A 7: the form with the interface shows the document filter result.
Filter after the document, can the document filtering result be shown to the user with the form at interface, pass through display result, can also verify further whether the process of filtering meets customer requirements, with reference to shown in Figure 6, show an interface synoptic diagram of document filter result in the object lesson of the present invention, be illustrated as three documents having examined, the document numbering is respectively: 00000010,00000011 and 00000012; As can be seen, it is the Administrator audit that document is numbered 00000010 document from the data message of document, and it is the CEO audit that document is numbered 00000011 document, and it is the SCM audit that document is numbered 00000012 document.
In sum, the present invention is by the identification parameter in the document metadata table that presets, with preset document and filter state table and carry out related, can make the user under the situation that document status changes, the filtration Status Type that described document is filtered in the state table adds on the document filtering interface, described filtration types can for " all; Examine; Audit " etc. content, the metadata expression formula that described document filters in the state table can also be used as filtercondition, document to be filtered is filtered according to document status, wherein, described metadata express formula can for be similar to " None～; Isnull (@Field, 0)＞0～; Isnull (@Field, 0)＜=0 " statement is described; the present invention removes to generate filtercondition by the filtration Status Type that the foundation user selects; and document to be filtered filtered, further, give the user with filter result by interface display; not only reduced the development and maintenance cost that need revise source code when document status changes; further, because document status information loads and resolves by unified method, also promoted the performance that document filters.
