T-SQL Cstr函数 MS SQL没有一个如vb一样的Cstr的函数。平常在T-SQL开发过程中,却很想要这样的一个功能,把一个输入的值转换为string, 如果用户输入一个NULL值,却把它转为一个N''值。因此也写了一个自定义函数: Cstr CREATEFUNCTION[dbo].[Cstr]
除了binary、varbinary和 image值以外,所有单个 SQL Server 值都被转换为单个 Visual Basic 值。 这些值将被转换为 Visual Basic 中的一维Byte()数组。 此数组的范围为Byte( 0 to length 1),其中 length是 SQL Server binary、varbinary或 image值中的字节数。
The first argument is the string or the column name. The second argument is the index of the character at which the substring should begin. The third argument is the length of the substring. Watch out! Unlike in some other programming languages, in T-SQL the indexes start at 1, not 0....
