Define the relationship between tables (MDB)
Show all When creating the relationship between tables, the associated fields do not have to have the same name, but must have the same field type, unless the primary key field is an "automatic number" field. Only when the "Automatic number" field is the same as the "field size" attribute of the "Number" field can the "Automatic number" field be matched with the "Number" field. For example,
The current 1.3.3 version of PYPYODBC on the Linux system has been able to read the MDB file with Chinese characters, no exception, but read the Chinese characters are all garbled.The following are reasonable inferences based on a number of phenomena:MDB files from the Windows system, where the Chinese characters using GB encoding is no doubt, but Linux system on the Mdbtools provided by the ODBC driver layer has been encoded conversion, the GB code i

What is an MDB database? Any network administrator who has a little experience in making a website knows that it is the most popular to use the "iis+asp+access" combination to build a Web site, most small and medium Internet sites use the "package", but the attendant security issues are becoming increasingly prominent.

Then in IE input data.asp path, found that IE shows a blank, right key-> view source file, out of Notepad, the content saved as an. mdb file, opened with access, found that a password was required, that is, at least the file header was corrupted.

Software to summarize, format for XLS, can you convert XLS file to MDB format? The first though
The MDB format file can export each of the tables contained in the Mdbtools tool to a CSV format file. Because of the PostgreSQL of the Access database and the format of the database, use Python's file processing to modify the resulting CSV file to the correct, recognizable format.
