Refering to Fig. 3, Fig. 3 is a kind of step flow chart of data export method provided in an embodiment of the present invention, methods described
Applied to a service end 100, as shown in figure 3, methods described includes：
Step 301, the total amount of data for obtaining data to be exported, divide the data to be exported according to the total amount of data
To preset the target data of number.
In the present embodiment, the total amount of data of the data to be exported can be million grades of big data magnitude, will wait to lead
Go out after data are divided into the target data of default number, the quantity amount per a target data is small compared with data to be exported
A lot, the internal memory shared when exporting target data is small.The default number can be default number, or user's
Self-defined numerical value.
For example, data to be exported is the basic document of whole city high school student, if the basic document of whole city high school student has 50
Ten thousand, when default number is 100 parts, then 500,000 data of whole city high school student can be divided into 100 parts, per a number of targets
According to there is 5000 data.
In the present embodiment, the data to be exported of million data volumes can be divided into the number of targets of at least two numbers
According to, per a target data relative to totality wait to export for, the quantity of data greatly reduces, relative to handling institute simultaneously
For having data to be exported, the storage resource of required occupancy, processing money during service end is handled target data
Source can be greatly decreased, and can improve the treatment effeciency of service end.
Step 302, the initial row parameter and end line parameter for obtaining every part of target data, join according to the initial row
Number and end line parameter read data since initial row and end line respectively, and according to the number read from the target data
According to generation target form.
In the present embodiment, the target data is read downwards according to the initial row parameter successively from the initial row,
The target data is read according to the end line parameter upwards successively from the end line, from the initial row successively downwards and
It can be to be spaced what the very short time was carried out to read the target data upwards successively from the end line, such as 0.3 millisecond, when
Interval time is very in short-term, it is believed that read downwards successively from the initial row target data and from the end line successively
The target data is read upwards to carry out simultaneously.Simultaneously from initial row and end line read data and generate target form can
To reduce the time, the efficiency of generation target form is improved.
For example, there are 5000 data per a target data, read the initial row and end line of the target data,
Assuming that starting behavior A0001 rows, terminate behavior A5000 rows, then from the next of the A0001 rows successively list to the target data
Row A0002 rows read data, while read number from the lastrow A4999 rows of the A5000 rows successively list to the target data
According to, after reading A0002 rows reading data, reading A0003 row data, after reading A4999 row data, from the reading of A4998 rows
Data ... are until read all 5000 datas.Target form is generated according to 5000 datas read from target data.
In the present embodiment, while since the initial row and end line of target data reading one can be saved by reading data
The time of part target data, save the time of generation target form.Specifically, while since initial row and end line read
The time that data are spent need to only may be successively read from initial row data to flower needed for the reading data mode of end of data row
The time taken spends half the time.
Step 303, the target form exported into preset data form, obtain target data form.
In the present embodiment, preset data form is the form of user's selection or system default form, for example, pre-
If formatted file can be the Excel forms of Microsoft.Because the data total amount of target form is smaller, by the target
Form is exported into preset data form, and the internal memory for obtaining taking required for the process of target data form is less, can save
Memory headroom.
For example, if including the target report of 5000 datas according to the 5000 datas generation read from target data
Table, then the target form including 5000 datas is exported into preset data form, obtain the target for including 5000 datas
Data form.Assuming that preset table be Microsoft Excel forms, then by the target form including 5000 datas export to
In Excel forms, the Excel forms for including 5000 datas are obtained.
In the present embodiment, target form is exported into preset data form, after obtaining target data form, Ke Yifang
Just service end is edited to target data form, and editor is carried out to target data form to be included deleting target data form
Subtract, increase and change the operation such as data, user's fast finishing can be caused to go out the data sheet of needs.If for example, target matrix
Lattice are the ecxel format texts of Microsoft, then content can be carried out to the target data form of ecxel forms and deletes, increase
And the operation such as modification, obtain the ecxel formatted data forms of user's request.
In the embodiment, the total amount of data of data to be exported is obtained, according to the total amount of data by the data to be exported
It is divided into the target data of default number；The initial row parameter and end line parameter of every part of target data are obtained, according to institute
State initial row parameter and end line parameter and read data since initial row and end line respectively, and according to from the target data
The data generation target form of middle reading；The target form is exported into preset data form, obtains target data form.
So, mass data derived from needs can be divided into more parts of target datas, be successively read target data generation target form, and
Target form is exported into preset data file simultaneously, obtains target data form, will can quickly export mass data, is improved
The export efficiency of data.
Referring to Fig. 4, Fig. 4 is the schematic flow sheet of another data export method provided in an embodiment of the present invention, the side
Method is applied to a service end 100, as shown in figure 4, methods described includes：
Step 401, the total amount of data for obtaining data to be exported, divide the data to be exported according to the total amount of data
To preset the target data of number.
In the present embodiment, the total amount of data of the data to be exported can be million grades of big data magnitude, will wait to lead
Go out after data are divided into the target data of default number, the quantity amount per a target data is small compared with data to be exported
A lot, the internal memory shared when exporting target data is small.The default number can be default number, or user's
Self-defined numerical value.
For example, data to be exported is the basic document of whole city university student, if the basic document of whole city university student has 100
Ten thousand, when default number is 100 parts, then 1,000,000 data of whole city university student can be divided into 100 parts, per a target
Data have 10000 data.
In the present embodiment, the data to be exported of million data volumes can be divided into the number of targets of at least two numbers
According to, per a target data relative to totality wait to export for, the quantity of data greatly reduces, relative to handling institute simultaneously
For having data to be exported, the storage resource of required occupancy, processing money during service end is handled target data
Source can be greatly decreased, and can improve the treatment effeciency of service end.
Step 402, the initial row parameter and end line parameter for obtaining every part of target data, join according to the initial row
Number and end line parameter read data since initial row and end line respectively, and according to the number read from the target data
According to generation target form.
In the present embodiment, the target data is read downwards according to the initial row parameter successively from the initial row,
The target data is read according to the end line parameter upwards successively from the end line, from the initial row successively downwards and
It can be to be spaced what the very short time was carried out to read the target data upwards successively from the end line.Such as 0.3 millisecond, when
Interval time is very in short-term, it is believed that read the target data downwards successively from the initial row, from the end line successively
The target data is read upwards to carry out simultaneously.Simultaneously from initial row and end line read data and generate target form can
To reduce the time, the efficiency of generation target form is improved.
For example, there are 10000 data per a target data, read initial row and the end of the target data
OK, it is assumed that starting behavior A0001 rows, terminate behavior A10000 rows, then from the A0001 rows successively list to the target data
Next line A0002 rows read data, while are read from the lastrow A9999 rows of the A10000 rows successively list to the target data
Access evidence, after reading A0002 rows reading data, A0003 row data are read, after reading A9999 row data, from A9998 rows
