The maximum value of 65 for M means that calculations on DECIMAL values 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 differs from before. (There is also a limit on how long the text...
Decimal precision can go to 24 places for a FLOAT. DOUBLE(M,D) A double precision floating-point number that cannot be unsigned. You can define the display length (M) and the number of decimals (D). This is not required and will default to 16,4, where 4 is the number of decimals...

sql decimal转换timestamp sql decimal转varchar 最近打算花时间看下 cockroachdb(这个名字太长后面全部用 cdb 代替, calcite 还会抽空继续~),对 cdb 我还是一无所知,所以先从看文档(v19.1.2)开始,边看边 mark 下,然后就可以开始看代码~ 首先cdb 文档很全, 我们从这个 https://www.cockroachlabs.com/docs/...
