Description
Technical Field
The invention belongs to the technical field of structured databases, and particularly relates to a method, a system, a device and a readable storage medium for adding fields in a form.
Background
With the development of internet technology, the data volume is rapidly increased, and solutions for storing structured databases are generated, and the database and the table are common;
and (5) library separation: the original relational database is split into a plurality of databases to store data, so that the throughput and the storage capacity are increased.
And (5) sub-table: splitting an original table into a plurality of tables according to a certain rule to finish the scattered storage of data, and determining the rule of the sub-table.
And the data throughput and the storage capacity are greatly increased by library and table division. But also creates technical difficulties. For example, after a database is divided into tables (the tables may generate thousands of sub-tables or more), fields need to be added, so that the thousands of sub-tables are affected by adding fields at the same time, and the services are not available due to the fact that the tables are locked; the data inconsistency problem may occur without adding fields simultaneously on the sub-table.
In general, an idle period with less user access is selected to directly add a field on an original service table; the existing scheme has the problem that if the system is a system with high heat (high concurrency and high throughput) accessed by a user, service intermittence (service temporarily unavailable) can be generated, and the user has the problem of perception and the like.
The newly added fields which are smooth after the database and the table are separated are continuously served, and the user does not perceive the newly added fields as the problems to be solved in the urgent database and table separation.

And the record is added on the newly added field table, so that the use of the original table is not affected, the granularity of the lock is small, and the service is not suspended. In addition, the fields are directly added in the original table, because the number of the original table is large, and thousands of sheets are actually arranged in the original table, if the fields are not added at the same time, the phenomenon of inconsistent data is easily caused. The method of the invention can add records to all the newly added field tables at the same time, thereby ensuring the consistency of the data.
The technical scheme of the invention is further described in detail through the drawings and the embodiments.

The identification ID is the identification ID of the data Q corresponding to the newly added field information. I.e. the new data P written in the new added field table a' comprises an identification ID, a field name, a field type, a field value and a field description;
by combining the identification ID and the newly added field information, a link relation between the data Q and the newly added field information can be established, and a foundation is laid for calling the newly added field information at the same time when the data Q is called subsequently.
And 3, configuring a data calling rule, wherein the data calling rule comprises that when each piece of data Q is called, the newly added field information corresponding to each piece of data Q is called at the same time.
The newly added field information of the data Q is simultaneously called, namely corresponding new data P is called in a newly added field table according to the identification ID of the data Q; combining the new data P with the data Q to obtain a piece of complete data K; the complete data K is fetched.
Combining the new data P with the data Q comprises the steps of: deleting information in the data P which is already in the data Q; and splicing the residual information of the data P on the data Q.
The method comprises the steps of configuring a data calling rule, finally realizing the purpose of calling newly added field information along with data Q, deleting information existing in the data Q in the data P when the new data P is combined with the data Q, and splicing the rest information of the data P on the data Q. The data is simplified, and the field is newly added in the final fetched complete data K compared with the data Q.
And the table A of the field to be added is an order table, a settlement table, a human resource table or a financial statement.
The data Q is text data, image data, voice data, or video data.
The newly added field information includes an identification ID, a field name, a field type, a field value, and a field description.
Example 2
In this embodiment, the principle of the present invention will be described by taking as an example a sub-table newly added field in a database storing order data. Assuming that the sub-tables include tables A and B, the fields "card holder" and "card number" need to be added to both tables A and B.
Specifically, the method for adding the field to the form comprises the following steps:
step 1, newly establishing a table A 'in a database, wherein the table A' is an newly added field table of the table A; newly building a table B' in a database; table B' is the newly added field table of Table B;
it should be noted that, the technical means adopted in the new tables a 'and B' are conventional database sub-table methods, and detailed discussion about how to create the sub-tables is omitted here.
Step 2, writing the newly added fields of ' card holder ' and ' card number ' of each data Q in the table A '; writing in table B' the newly added fields "card holder" and "card number" for each data Q in table B;
specifically, when writing the newly added field "card holder" and "card number" of each piece of data Q, the identification ID of the data Q is called, the identification ID and the field name, field type, field value and field description of the newly added field are synthesized into one piece of new data P, and then the new data P is stored in the newly added field table (table a 'or table B'). In this embodiment, the identification ID is an order number, and assuming that one piece of order data in the table a is (1, '2020102713552554124',1001,1,1,35.00, '2020-10-2713:58:07', 'tn_202010271360', 'and then two pieces of data are corresponding to the order in the table a', wherein one piece of data is (1, '2020102713552554124', 'card_wner', 0, 'winning', 'owner of the card') and the other piece of data is (1, '2020102713552554124', 'card_no',1, '6225880150312112', 'card number').
Step 3, the configuration database executes the following steps when receiving a query request:
step 3-1, one or more pieces of data Q in the sub-table are called according to the query request;
step 3-2, for each piece of data Q in step 3-2, calling one or more corresponding pieces of new data P in the newly added field table according to the identification ID of the data Q;
step 3-3, combining one or more pieces of new data P which are called by the step 3-2 with the data Q for each piece of data Q, and obtaining a piece of complete data K after combination; the complete data K is returned to the originator of the query request.
When the data P and the data Q are combined, the information in the data P, which is already in the data Q, is deleted, and then the rest information of the data P is spliced on the data Q. For example, the order data in Table A (1, '2020102713552554124',1001,1,1,35.00, '2020-10-2713:58:07', ' tn_202010271360', ') and the data in Table A ' (1, '2020102713552554124', ' card_wner ',0, ' won's administration ', ' card owner ') is synthesized as (1, '2020102713552554124',1001,1,1,35.00, '2020-10-2713:58:07', ' tn_202010271360', card_wner ',0, ' won's administration ', ' card owner ').

The writing module 2 is configured to write the newly added field information of each piece of data Q in the table a into the newly added field table a'.
Specifically, the newly added field information includes a field name, a field type, a field value, and a field description;
when writing the newly added field information of the data Q in the newly added field table A', the writing module 2 firstly calls the identification ID of the data Q; the identification ID and the newly added field information are then combined into a new piece of data P to be written into the newly added field table a'. The identification ID is the identification ID of the data Q corresponding to the newly added field information. I.e. the new data P written in the new added field table a' comprises an identification ID, a field name, a field type, a field value and a field description;
by combining the identification ID and the newly added field information, a link relation between the data Q and the newly added field information can be established, and a foundation is laid for calling the newly added field information at the same time when the data Q is called subsequently.
The configuration module 3 is used for configuring data calling rules; the data calling rule includes that when each piece of data Q is called, newly added field information corresponding to each piece of data Q is called at the same time.
Specifically, the configuration module 3 directly configures a calling rule of the database, and when the original data in the table a is called and each piece of data Q is configured to be called, the newly added field information of the data Q is called simultaneously. The newly added field information of the data Q is simultaneously called, namely corresponding new data P is called in a newly added field table according to the identification ID of the data Q; combining the new data P with the data Q to obtain a piece of complete data K; the complete data K is fetched.
Combining the new data P with the data Q comprises the steps of: deleting information in the data P which is already in the data Q; and splicing the residual information of the data P on the data Q.
The method comprises the steps of configuring a data calling rule, finally realizing the purpose of calling newly added field information along with data Q, deleting information existing in the data Q in the data P when the new data P is combined with the data Q, and splicing the rest information of the data P on the data Q. The data is simplified, and the field is newly added in the final fetched complete data K compared with the data Q.
And the table A of the field to be added is an order table, a settlement table, a human resource table or a financial statement.
The data Q is text data, image data, voice data, or video data.
