When using odbc-api
currently, the Text
storage content of the database is dynamic. If a certain column of text stored in the database has a length of 1500, I set Text:: max_str_len
length to 1280, and an error of content truncation will occur.
However, when I set the max_str_len length of 9999, the content of the stored column may be larger than 9999, resulting in an uncontrollable content length, and when the odbc-api reads, the text column will be truncated.
If I set the default value according to the maximum value of Text in the Pg database, there will be a problem of memory allocation failure.
So, please tell me how to dynamically control the Text::max_str_len
of odbc-api.
