Method is used for solving the problem, as shown in figure 1, the method comprising the steps of：
Step 101, server obtain arbitrary field for building table statement of the raw data table of user in database
Corresponding annotation information.
The annotation information is the explanation of the field purposes for building table statement to correspondence.
Specifically, described building in table statement at least includes：Field, data type, annotation information and content.
The field that builds in table statement is that data type is used for retouching for distinguishing different table statement of building
The type of field corresponding content is stated, is not only in the annotation information concrete to the corresponding field for building table statement
Description, the type of the field corresponding content, the annotation can also be obtained according to the annotation information
The detailed description of the corresponding all the elements information of field is contained in information.
To build table statement " user_id (Identity, identity number) BIGINT COMMENT'
As a example by member numeral ID' " and " reg_phone STRING COMMENT' landline telephone ' ", user_id
It is all the field of building table statement with reg_phone, corresponding table statement can be built to which according to the two fields
Make a distinction, by taking the corresponding data type of user_id and annotation information as an example, BIGINT represents field pair
The data type of content is answered, COMMENT' member's numeral ID' is annotation information, in the annotation information
Member numeral ID represent the purposes of the field be for describing member ID, and also can basis
The annotation information obtains which kind of data type is the corresponding content of the field be, such as：Digital ID represents institute
The data type for stating the corresponding content of field is numeral, therefore, it can according to the above-mentioned note that builds in table statement
The information of releasing is determined with the presence or absence of sensitive information in the corresponding content of field, due to the above-mentioned word that builds in table statement
Section belongs to the name of specification, can determine and whether there is in the corresponding content of the field from the field
Sensitive information, when table statement is built for " u_id BIGINT COMMENT' member numeral ID' ", u_id
For the field for building table statement, although can be made a distinction to building table statement according to the field, but from
What the purposes that the field cannot be obtained in the field is, i.e., cannot show which kind of the field corresponds to
Content, also cannot just judge with the presence or absence of sensitive information in the corresponding content of the field, and from the word
Section corresponding annotation information " member numeral ID " can determine that the purposes of the field be to member ID
