Embodiment Construction

[0036] Continue to explain the data structure of the data table in detail here. Table 1 shows a common data table (taking student achievement table as an example).

[0037]

[0038] Table 1

[0039] There are 3 records in Table 1, corresponding to 3 students (Zhang San, Li Si and Wang Wu). Each record contains 4 common fields (key1, key2, key7 and key8) and 1 extension field. Usually, only the extension field has subfields. The subfields included in the extension field of each record in Table 1 can be selected from key3-key6, and the subfields in the extension fields included in each record can be different. For example, Zhang San's record contains subfields key3, key4, and key6, while Li Si's record contains subfields key3, key5, and key6.

[0040] As mentioned above, in order to clarify the correspondence between each sub-field and its value in the extension field and avoid field value misplacement, the content of the extension field is usually stored in the form of ke...

Abstract

A method and device for verifying a record to be written are disclosed. At least one subfield in the extended field of the data table is a designated subfield. When a record needs to be written into the data table, according to the key-value pair corresponding to the specified subfield in the extended field contained in the record to be written, the unique identifier corresponding to the record to be written can be determined, and then according to the corresponding The unique identifier of the field value duplication check for the record to be written.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular, to a method and device for verifying a record to be written. Background technique [0002] As we all know, a data table is a data structure commonly used by a database to store data. In a data table, each row is a record, and each column corresponds to a field (or key, keyword, key, etc.), and the content of each field contained in a record is determined, and the record is determined. A record can contain several common fields and one extended field. It is worth emphasizing that every record must contain all common fields, but not every record must contain extended fields. [0003] It should be noted that for each public field contained in a record, the content of the public field is usually a value, that is, the value of the public field; for an extended field contained in a record, the content of the extended field The content may be the value o...
