What is double equivalent in SQL?

The decimal(x,y) SQL Server type is for when you want exact decimal numbers rather than floating point (which can be approximations). This is in contrast to the C# “decimal” data type, which is more like a 128-bit floating point number. MSSQL’s float type is equivalent to the 64-bit double type in .

How do you measure length in SQL?

The LEN() function returns the length of a string. Note: Trailing spaces at the end of the string is not included when calculating the length. However, leading spaces at the start of the string is included when calculating the length. Tip: Also look at the DATALENGTH() function.

What is the long datatype?

long: The long data type is a 64-bit two’s complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1.

Unicode character string data types, for example nchar, nvarchar, ntext, etc.

What is length in SQL?
