Example-1 : When the argument holds a positive number. Key Difference: Generally, Integers can be described as whole numbers meaning that they do not have any fractional parts, whereas float describes a number that can be only written in a decimal number system. The only difference to note with the two technologies is that in SQL Server the scale must be between 0 and the precision, i.e.. 0 <= s <= p, however in Oracle this scale value can range from -87 to 127. INT is a synonym for INTEGER SQL defines distinct data types named by the following keywords: CHARACTER, CHARACTER VARYING, BIT, BIT VARYING, NUMERIC, DECIMAL .

But this trade-off comes at the cost of precision. Compare this to the many varieties of int: So for every row and every index that includes this value, we lose storage space. SQL> From this we can make a number of conclusions: NUMBER: As mentioned previously, since NUMBER is an internal datatype, it is not the fastest of the numeric types. Remarks. TINYINT SMALLINT Storage Size 1 Byte 2 Bytes Minimum Value 0 -32,768 (-2^15) The rank of a row is one plus the number of ranks that come before the row in question.

DECIMAL[(p[,s])] and NUMERIC[(p[,s])] in SQL Server can be represented by NUMBER(p,s) in Oracle. TINYINT, SMALLINT, INT and BIGINT are all the same in the sense that they are all exact number data types that use integer data. Example: In the travel table, there are three columns: id, departure, and arrival. It is preferred less. I know that the NUMERIC and DECIMAL data types in SQL Server work the same: the syntax for creating them is the same, the ranges of values you can store in them is the same, etc. INTEGER: Like NUMBER, the INTEGER type is an internal type, but the extra constraints on this datatype make it substantially slower than NUMBER. As long as they are all numbers is it better to use bigint, int, numeric or some other datatype when storing these types of values. One byte to store the data. Post very short and objective and I hope it helped clarify the difference between @@ ERROR and ERROR_NUMBER ().

Although I would prefer if it would be translated into NUMBER (38). char stores upto 8000 bytes. numeric and decimal are the same thing and take a precision (number of digits) and scale (number of decimal places). Querying to NCHAR or NVARCHAR is a bit slower then CHAR or VARCHAR. The range of BIGINT is -9223372036854775808 to 9223372036854775807 or 0 to . It is widely preferred datatype.
