Description of drawings
Fig. 1 is a kind of configurable information query method process flow diagram based on infosystem of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, a kind of configurable information query method process flow diagram based on infosystem for the embodiment of the invention comprises:
Step S101, receive the query configuration information of user's input, generate data configuration file, data configuration file is preferred but be not limited to the XML formatted file, and it comprises: the title of condition judgment expression formula, query operator, inquiry field, inquiry word segment type and be used to receive and the external variable of storing queries field value.The condition judgment expression formula is supported if-else, and two kinds of switch-case are specifically as shown in table 1:
Table 1 condition judgment expression formula configuration format
In the last table configuration of condition judgment expression in the data configuration file has been described, as: inquire about the age greater than 60 years old people, the result after the configuration is:
<switch?exp＝”trim(#name#)<>”and#age#>0”>
<case?value＝’true’>
<if?exp＝”#age#>60”>
＜success〉type=' the elderly '＜/success 〉
</if>
</case>
<case?value＝’false’><！[cdata[age<>0]]></case>
</switch>
Query operator is supported: bracket " () ", add "+", subtract "-", take advantage of " * ", remove "/", with " and " or " or ", equal "=", more than or equal to "＞=", less than "＜", smaller or equal to "＜=", be not equal to "＜＞", fuzzy " like ", a left side fuzzy " leftlike ".The function of supporting comprises: trim, tonumber, tochar and todate.
Trim for example is used to filter the space after: trim (' woman ')=' woman '
Tonumber be used for the character conversion numerical example as: tonumber (' 322 ')＞300
Tochar be used for digital conversion be character for example: tochar (' 322 ')＞' 300 ')
Todate is used for the character type date literal is converted to the date type data
For example: todate (' 2010-2-3 ')＞sysdate
These functions are used in the configuration file, for example: the inquiry sex is woman people
＜if exp=" trim (' #sex# ')=woman "
＜success〉type=' woman '＜/success 〉
</if>
About title, the inquiry word segment type of inquiry field and be used to receive and the configuration format of the external variable of storing queries field value is:
＜filed operator=" operational character " colname=" corresponding row name " datatype=" data type " value=" value "/,
As:＜filed operator="=" colname=" name " datatype=" character " value=" Zhang Shan "/
The logic that produces is name 〉=' Zhang Shan ', value also can be used to receive outside querying condition for the external variable name.
＜sql exp=" expression formula " [result]＜/sql 〉
As:＜sql exp=" #name#＜null and#name#〉0 " name=' Zhang Shan '＜/sql 〉
If the logic that produces for external variable name for empty and greater than 0 then return name=' Zhang Shan '.
Also comprise the configuration of showing Query Result, comprising: to the configuration of the graphical displaying of the pie chart of Query Result, histogram, pie chart
The concrete configuration mode of data configuration file is the mode by the front-end configuration interface, imports the data configuration file that generates the XML form behind each configuration item automatically.
Step S102, the resolution data configuration file generates the SQL statement for data base querying.The one-piece construction of resolving the back data configuration file is as follows:
＜sqlquery name=" unique title "
<select>
The SQL statement referencable variable is as the Ming Cheng $wherenamel$ of where
Select*from?student?where?name>’#name#’$wherenamel$
</select>
<where?name＝”wherenamel”>
<if>...</if>
<switch>...</switch>
<field>...</field>
</where>
＜table〉definition list mode output form＜/table
<picture>
＜line〉the definition line graph＜/line 〉
＜pie〉the definition cake chart＜/pie 〉
＜bar〉the definition histogram＜/bar 〉
<picture>
<datadefine>
＜merger〉the merging row＜/merger 〉
＜sum〉the total row＜/sum 〉
＜cal〉calculated column＜/cal 〉
<datadefine>
</sqlquery>
Built-in variable and external variable are the modes of a kind of Data transmission of internal system use, are transparent to the user.
External variable: its form is # external variable name #, and the name that the name of the corresponding external inquiry condition entry of external variable name frame or the HashMap object by java import into just can be got the data qualification value of importing into the outside by this name.
Built-in variable: its form is $ built-in variable name $, built-in variable name correspondence be the name of where node in the configuration file, Ji $wherenamel$ just can be put into the SQL statement that each node generated the optional position of whole SQL with the ease of assembly logic by this name.
Step S103 calls data source execution query statement and returns Query Result, promptly by the SQL statement Query Database after resolving, obtains Query Result.The data volume of record queries time or inquiry when query statement carried out in record in the time of inquiry is so that the data of record queries overlong time and excessive data volume.
Step S104 reaches the total that is configured into the line data row or column, ranks conversion, Merge Cells, the data cross of described Query Result and described displaying Query Result the processing of newly-increased calculated column (as calculating number percent).And the data after the caching process refresh use for export or demonstration.
Step S105 is according to the pattern of setting in the configuration of showing Query Result, as the color of the foreground and the background colour of alignment thereof, cell, font, add the data after url such as is connected at the displaying processing such as pattern that html can support.Mainly graphically show by pie chart, histogram or line graph.
The present invention also provides a kind of configurable information query system based on infosystem, comprise: the data configuration file generation module, be used to receive the query configuration information of user's input, generate data configuration file, described data configuration file comprises: the title of condition judgment expression formula, query operator, inquiry field, inquiry word segment type and be used to receive and the external variable of storing queries field value; The data configuration file parsing module is used for the resolution data configuration file, generates the SQL statement of data base querying; Enquiry module is used to call data source execution query statement and returns Query Result.
Wherein, this system also comprises: the performance inventory module is used for the data volume of when carrying out query statement record queries time or inquiry.
Wherein, this system also comprises: the data formatting module is used for the processing with the total that is configured into the line data row or column, ranks conversion, Merge Cells, data cross and the newly-increased calculated column of described Query Result and described displaying Query Result; The Query Result display module is used for according to the data after the pattern of setting in the configuration of showing Query Result (color of the foreground of alignment thereof, cell and background colour, font, add url the pattern that html can support such as is connected) the displaying processing.
Wherein, this system also comprises: data cache module is used for the data after the described processing of buffer memory.
Above embodiment only is used to illustrate the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
