As of MySQL 8.0.17, the ZEROFILL attribute is deprecated for numeric data types and will be removed in a future MySQL version. Consider using an alternative means of producing the effect of this attribute. For example, applications could use the LPAD() function to zero-pad numbers up to th...

For instance, if we define a column as DECIMAL(10,2), it can store numbers with up to 10 digits, and up to 2 digits to the right of the decimal point.In MySQL, instead of the DECIMAL keyword, we can also use the "DEC", "FIXED" and "NUMERIC" keywords because they are synonyms ...
上面代码中,long_len 值为10,longlong_len 值为19,unsigned_longlong_len值为20。 neg表示是否是负数,直接看正数的处理分支,负数同理: 当输入的数值串长度等于 10 时MySQL 可能使用 LONG_NUM 或LONG_NUM 表示 当输入的数值串长度小于 19 时MySQL 使用 LONG_NUM 表示 当输入的数值串长度等于 20 时MySQL 可...

IfDis omitted, the default is 0. IfMis omitted, the default is 10. The maximum value of 65 forMmeans that calculations onDECIMALvalues are accurate up to 65 digits. This limit of 65 digits of precision also applies to exact-value numeric literals, so the maximum range of such literals di...

MySQL permits a nonstandard syntax: FLOAT(M,D) or REAL(M,D) or DOUBLE PRECISION(M,D). Here, “(M,D)” means than values can be stored with up to M digits in total, of which D digits may be after the decimal point. and For maximum portability, code requiring storage of approximat...
Your script is using the connection string containing DRIVER={...} option. This means that all options are specified in the connection string and can be visible there (unlike DSN where options are specified independently). Therefore, I do not see how any extra settings might affect the connect...
