The wildcard may include, for example: % (instead of one or more characters), - (instead of only one character), [ charlist ] (any single character in the character column), [ ^ charlist ] (any single character not in the character column), or [! charlist ] (any single character not in a character string), without limitation.
Wherein, the operator may include, for example: AND (combining two conditions AND taking value true when both conditions are true), OR (combining two conditions AND taking value true when one of the two conditions is true), AND NOT (used with other operators, the inverse operation).
By way of example, the target structured query statement may be: select from student where score, between 90and 100 (query student table for all information of students with score 90-100). The identifier of the database may be: a student; the identification of the target object may be: the achievement.

Illustratively, the plurality of preset components may include, for example: the preset rule can be, for example: the select component is located before the from component, the from component is located before the table name component of the data table, and the table name component of the data table is located before the where component.
According to the technical scheme, the multiple components for querying data are obtained when the selection operation aiming at the multiple components is detected on the component selection interface, so that the visual selection of the multiple components for querying data by non-developers is realized. In addition, after the plurality of components for querying data are obtained, the plurality of components for querying data can be sequenced according to a preset rule, so that a target structured query statement can be generated according to the sequenced plurality of components, and the problem of low efficiency caused by the fact that the target structured query statement needs to be manually input in the prior art is solved.
203. And acquiring the identity of the first user and the identity of the second user, wherein the data access authority corresponding to the identity of the first user is different from the data access authority corresponding to the identity of the second user.
The identity of the first user may be, for example, a job number or other identity of the first user, and the identity of the second user may be, for example, a job number or other identity of the second user, which is not limited herein. It will be appreciated that the identity of the first user is different from the identity of the second user.
The data access right corresponding to the identity of the first user is different from the data access right corresponding to the identity of the second user, and can be understood as follows: the data access right corresponding to the identity of the first user is higher or lower than the data access right corresponding to the identity of the second user, which is not limited herein.
