The data type `NUMBER(p,s)` of oracle has some different of doris decimal type in semantics. For Oracle Number(p,s) type： 1. if s<0 , it means this is an Interger. This `NUMBER(p,s)` has (p+|s| ) significant digit, and rounding will be performed at s position. eg: if we insert 1234567 into `NUMBER(5,-2)` type, then the oracle will store 1234500. In this case, Doris will use int type (`TINYINT/SMALLINT/INT/.../LARGEINT`). 2. if s>=0 && s<p , it just like doris Decimal(p,s) behavior. 3. if s>=0 && s>p, it means this is a decimal(like 0.xxxxx). p represents how many digits can be left to the left after the decimal point, the figure after the decimal point s will be rounded. eg: we can not insert 0.0123456 into `NUMBER(5,7)` type, because there must be two zeros on the right side of the decimal point, we can insert 0.0012345 into `NUMBER(5,7)` type. In this case, Doris will use `DECIMAL(s,s)` 4. if we don't specify p and s for `NUMBER(p,s)` like `NUMBER`, the p and s of `NUMBER` are uncertain. In this case, doris can not determine p and s, so doris can not determine data type.
