Detailed Description
The embodiments of the present invention will be described below with reference to the accompanying drawings, and it should be understood that the embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
In view of the fact that in the prior art, when Excel data is imported, the content needs to be restrained, inconvenience exists in use, and the use experience of software is affected, the embodiment of the invention provides a data importing scheme, so that when Excel data is imported, the content does not need to be restrained, and the use experience of a user is improved.
The following describes the scheme provided by the embodiment of the invention in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a data importing method, which is used for importing table data, and may include the following steps:
step 101, a table file to be imported into a database is acquired.
Step 102, analyzing the table file, and acquiring the effective title, the custom title, the title structure and the position of the data line in the table file based on the analysis result; the custom titles are column names in a table, the title structures are used for representing hierarchical relations among the custom titles, and the effective titles refer to custom titles of the last hierarchy in the custom titles containing the hierarchical relations.
In one possible implementation, the custom header and header structure in the parsing result are represented in the form of a recursive array.
It should be noted that, in the specific implementation, it is necessary to implement a table file with a behavior title, and since the tree data structure can further store the relationship of the parent and child titles on the basis of the storage value, after parsing the table file, the custom title can be stored by using the data structure of the tree. However, since page display optimization, storing with a tree structure is not well suited, it is more feasible to store custom titles in a recursive array storage format.
In one possible implementation, the column merge cells are assigned only once when they are assigned in the recursive array when it is determined that the column merge cells are included in the active header.
In particular, the repeated columns in the effective title are determined to include the repeated columns, and the repeated columns are prompted to a user for subsequent de-duplication processing of the repeated columns in the data. However, if the valid header contains a column merge cell, it is specially processed, i.e., only once assigned when assigned in the recursive array, and no deduplication is performed.
And 103, based on the effective title, the custom title, the title structure and the positions of the data lines, re-splicing according to a preset sequence to generate a data table.
And step 104, importing the data table generated by the re-splicing into a database.
In one possible implementation, importing a data table generated by re-splicing includes:
displaying a data table generated by re-splicing and an editing key for editing the data table generated by re-splicing to a user, wherein the data table generated by re-splicing comprises a corresponding relation between a custom title and column names in a database;
editing the data form generated by the re-splicing based on the selection operation of the editing keys by the user;
And when the user is determined to finish editing the data table generated by the re-splicing, importing the data table edited by the user into a database.
When the method is implemented, after traversing all data in the table file, displaying a data table generated by re-splicing and an editing key for editing the data table generated by re-splicing to a user, wherein the regenerated data table comprises a corresponding relation between a custom title and a column name in a database, the user reviews the table file again, and can trigger the editing key to delete unnecessary data, and editing the data table generated by re-splicing based on the selection operation of the editing key by the user; when the user is determined to finish editing the data table generated by the re-splicing, importing the data table edited by the user into a database, wherein the data table comprises a custom title, a title structure and corresponding data.
As shown in fig. 2, the content in the table in fig. 2 is spliced again to generate the data table shown in fig. 3 and is imported into the database by the data importing method provided by the embodiment of the present invention, and the specific flow of the data importing method provided by the embodiment of the present invention is described in detail with reference to fig. 2 and 3.
As shown in fig. 4, in step 401, a table file to be imported into a database is acquired.
Step 402, analyzing the table file, and acquiring the effective title, the custom title, the title structure and the position of the data line in the table file based on the analysis result.
The custom titles are column names in the table, such as serial numbers, employee names, certificate types and the like; the title structure is used for representing the hierarchical relation between the custom titles, and three titles of income, deduction and tax are additionally arranged under the condition of initial accumulation; the effective titles refer to the last-level custom titles in the custom titles containing the hierarchical relationship, in fig. 2, the titles in columns a-G have only one layer, then the custom title in each column is the effective title, the three columns H-J contain two layers of titles, and then the last layer is the income, deduction and tax is the effective title.
It should be noted that, as shown in fig. 2, in the H-J column of the self-calibration title, the parent-child titles such as the initial accumulation and income, deduction, and tax are included, so the custom titles are stored in the form of a recursive array to preserve the hierarchical structure between the titles.
In the specific implementation, the parsing of the table file further includes obtaining the positions of the data lines in the table file, firstly presetting a distinguishing threshold, then traversing the table content line by line, determining a certain line as a data line when the data in the certain line is traversed to be greater than or equal to the distinguishing threshold, and finally returning the subscript of the data line, and taking the line as the boundary between the data line and the title.
In fig. 2, the distinguishing threshold may be preset to be 3, when the first and second lines of content are traversed, the digital content is not traversed, when the third line of content is traversed, the numbers in the cells "1", "120106199408294000", "6000", "12" and "30" are all identified, and then the number of the cells containing the digital content in the line is 5 and is greater than the distinguishing threshold 3, so the third line is determined as the boundary between the data line and the title, i.e. the first and second lines of title content, and the data content starts from the third line.
It should be noted that, the data in the table file is traversed until the last line of traversal is completed, which is regarded as the completion of table content parsing. The method comprises the steps of determining that a repeated column exists in an effective title, and prompting the repeated column to a user for carrying out repeated processing on the repeated column in data. However, if the valid header contains a column merge cell, it is specially processed, i.e., only once assigned when assigned in the recursive array, and no deduplication is performed.
In fig. 2, the valid header contains a merging cell because the document number is merged with the E column in too long a D column. When traversing the data lines of columns D and E, the certificate number only needs to be assigned once in the recursion array.
And step 403, after the analysis of the table contents is completed, displaying the data table generated by re-splicing and an editing key for editing the data table generated by re-splicing to a user, wherein the data table generated by re-splicing comprises the corresponding relation between the custom title and the column names in the database, and editing the data table generated by re-splicing based on the selection operation of the editing key by the user.
In practice, after the table contents are parsed, the user can review the table contents again and delete unnecessary data.
Step 404, importing the data table generated by re-splicing into a database and storing.
In specific implementation, the user checks the data in the table, and after confirming that the content in the table is not redundant or missing, the data table generated by re-splicing is imported into the database, and the table file shown in fig. 3 is generated and stored. As shown in fig. 3, the table file generated by the data importing method provided by the embodiment of the present invention imports the data content in fig. 2 accurately, and is not affected by repeated columns and multi-level title structures, so that the title and the data are automatically parsed without discussing constraint conditions with the user, a large amount of communication cost is saved, and the use experience of the user is improved.
