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...
decimalFixed precision and scale numbers. When maximum precision is used, valid values are from - 10^38 +1 through 10^38 - 1. The ISO synonyms fordecimalp (precision) The maximum total number of decimal digits that can be stored, both to the left and to the right of the decimal point...

会对每个 field 分别进行 prefix-free 的 encode, encode 时会添加 field type, 对于主键需要保证 order 属性。 主键value 则由: kv pair 的 checksum(4 bytes) value type column-family 中指定列排除 primary 列后的其他列的值 组成, 一般 value type 是TUPLE, 所以 value 会先根据 column-id 排序,然后 ...
Set Default value for column 'd_bigint' in table 'datatype' Column 'd_decimal' in table 'datatype' have no comments. Column 'd_decimal' in table 'datatype' is not allowed to been nullable. Set Default value for column 'd_decimal' in table 'datatype' ...
解决方法:重新修改SQL语法,并为NUMERIC或DECIMAL类型字段指定精度。 ERRCODE_CANNOT_COERCE 报错:cannot cast type date to integer 问题原因:无法将DATE类型转换为INT类型。 解决方法:重新修改SQL语法。 ERRCODE_UNDEFINED_SCHEMA或者ERRCODE_INVALID_SCHEMA_NAME ...
you must define the parameter to be of a data type castable from DECIMAL (for example CHAR or DOUBLE) and explicitly cast the argument to this type. In the case of DOUBLE, you do not need to explicitly cast a decimal argument to a DOUBLE parameter, because the database promotes it autom...
Compares this SqlDecimal instance to the supplied SqlDecimal object and returns an indication of their relative values. ConvertToPrecScale(SqlDecimal, Int32, Int32) Adjusts the value of the SqlDecimal operand to the indicated precision and scale. Divide(SqlDecimal, SqlDecimal) The division ope...
DEC(size,d)Equal to DECIMAL(size,d) Note:All the numeric data types may have an extra option: UNSIGNED or ZEROFILL. If you add the UNSIGNED option, MySQL disallows negative values for the column. If you add the ZEROFILL option, MySQL automatically also adds the UNSIGNED attribute to the...
如果最不常见的类型解析为FLOAT,则应用特殊规则。 如果任何参与类型为精确的数值类型(TINYINT、SMALLINT、INTEGER、BIGINT或DECIMAL),则推出的最不常见类型均为DOUBLE,以避免可能的数字丢失。 如果最不常见的类型是STRING则按照排序规则优先规则计算排序规则。
