Description
The ODBC function SQLColAttribute returns string values e.g. for column name. When the user-defined buffer is too small to fit the whole string, the function returned the length of the truncated string instead of the length of the available string.
Workaround
Increase the user-defined buffer.
Fix
According to the ODBC standard, the driver returns the total number of bytes (excluding the null-termination byte for character data) available.
