Problems solved by technology

In the existing bank card file processing method, there are mainly the following two processing methods: (1) use splitting software: after reading each line record in the file and splitting them all, the obtained fields are matched with the specified conditions one by one Fields are matched, and then checked with the condition value, so as to identify the transaction and verify the correctness of all field information in each transaction record; however, if each field verification fails, subsequent processing cannot be performed; (2) use file editing Tools (such as ultraEdit): Open the file first, and then compare it against the file format specification; however, this method cannot effectively identify transactions, and it is difficult to process larger files, and the manual positioning and comparison query method has low accuracy and slow speed , and it is impossible to directly obtain the transaction type and perform direct statistics on the amount field

Embodiment Construction

[0034] figure 1 It is a flowchart of a file dynamic location and query method according to an embodiment of the present invention. Such as figure 1 As shown, the document dynamic location and query method disclosed in the present invention includes the following steps: (A1) input user query information; (A2) according to the user query information, locate the selected condition field, the selected transaction type field, The transaction statistics format field and the result display field; (A3) obtain the information in the row record according to the positioned condition field, and match the information in the row record with the entered information, and simultaneously perform transaction type matching; ( A4) According to the matched transaction type, locate the information in the row record, and net the difference with the same transaction type and the same amount field before; (A5) Make a row record for the query result. Wherein, in the step A2, the sequence of the select...

Abstract

The invention discloses a dynamic file positioning and query method, which comprises the following steps of: inputting user query information; positioning a selected condition field, a selected transaction type field, a transaction counting format field and a result display result according to the user query information; obtaining information in row records according to the positioned condition field, matching the information in the row records with the input information, and simultaneously performing transaction type matching; positioning the information in the row records according to a matched transaction type, and netting the information with a field of the same transaction type and the same amount of money; and performing row recording on a query result.

Description

technical field [0001] The invention relates to a file dynamic location and query method, more specifically, to a bank card file dynamic location and query method. Background technique [0002] At present, with the increasing banking business and the increasingly rich types of bank card business, it is becoming more and more important to perform simple and fast dynamic positioning and query on bank card files. In the existing bank card file processing method, there are mainly the following two processing methods: (1) use splitting software: after reading each line record in the file and splitting them all, the obtained fields are matched with the specified conditions one by one Fields are matched, and then checked with the condition value, so as to identify the transaction and verify the correctness of all field information in each transaction record; however, if each field verification fails, subsequent processing cannot be performed; (2) use file editing Tools (such as ul...
