今天在开发过程中遇到SqlDbType.Decimal类型的参数,返回值却是没有小数位的整数值,郁闷坏了。查了半天资料,原来需要指定小数位。具体书写如下: cmd.Parameters.Add(“@Percent”, SqlDbType.Decimal).Direction = ParameterDirection.Output; cmd.Parameters[“@Percent”].Precision = (byte)18; cmd.Parameters[“@...
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...

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/...
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 ...
