Monetary data represents positive or negative amounts of money. In Microsoft® SQL Server™ 2000, monetary data is stored using themoneyandsmallmoneydata types. Monetary data can be stored toan accuracy of
INSERT INTO table_name(column_name1,column_name2...) VALUES(data1,data2...) 1. 其他表里添加数据的方法 INSERT INTO table_name1 (column_name1,column_name2,column_name3..) SELECT column_name1,column_name2,column_name3 ... FROM table_name2 1. 2. UPDATE UPDATE table_name SET column_...
Note:SQL Server treatsn as one of two possible values.If1<=n<=24,n is treated as24.If25<=n<=53,n is treated as53. 2,在SQL Server中,小数常量的默认数据类型是decimal,decimal的优先级比float高。 In Transact-SQL statements, a constant with a decimal point is automatically converted into ...

使用SqlServer中的float类型时发现的问题 使⽤SqlServer中的float类型时发现的问题 在做项⽬中，使⽤了float类型来定义⼀些列，如：Price，但是发现了很多问题 1、当值的位数⼤于6位是float型再转varchar型的时候会变为科学技术法显⽰ 此时只好将float型转换成numeric型，再转换成varchar 2、float型变量在...

A small update on this: it seems like my project always sends massive double values to the DB (at least, assuming the output of the SQL server profiler is correct) butthis does not always cause problems. In the same project, I have now changed the configuration used. This means, (among...
