Check if the constant value is what you intended. If the value is correct, use a wider data type for the variable. Examples expand all Result Information Group:Numerical Language:C | C++ Default:Off Command-Line
The byte, short, int, and long are all signed data types. For a signed data type, half of the range of values stores positive number and half for negative numbers, as one bit is used to store the sign of the value. For example, a byte takes 8 bits; its range is -128 to 127. ...

There are four type modifiers in C++: short long signed unsigned Here's a brief summary: Data TypeSize (in Bytes)Meaning signed int 4 Used for integers (equivalent to int). unsigned int 4 Can only store non-negative integers. short 2 Used for small integers.Range: -32768 to 32767 long...

Variables in MATLAB of data type (class) uint8 are stored as 1-byte (8-bit) unsigned integers.
费老大劲才排查出来是这个原因。问题是否与MariaDB相关不清楚,但是讲道理这是一个标准的datatype,workbench应该无差别支持才对。如果大家遇到workbench对于特定的表莫名其妙闪崩,可以考虑是否与unsigned有关。 以下为eventlog参考: 应用程序: MySQLWorkbench.exe
