Maximum size of char datatype is 2000 bytes (2000 char’s).It will store non-Unicode char’s in the form of 1 char = 1 byte.It is a fixed-length datatype (static).Supporting to store localized data/ information (only English language). Note: Character Datatypes are again classified into two categories. Those areįor a better understand, please have a look at the below diagram. In database string is represented with single quotes ‘ ‘.Ĭharacter datatypes are storing two types of string format data. These Datatypes are used for storing “string” format data only. Precision = 7 2) Character Datatypes in Oracle: When we use -> Number(P, S) -> Store float values onlyĬounting all digits including left & right sides of given float expression or counting all digits including left & right sides digits of a decimal point.Įxample: 9999.99 => Precision = 6 Scale(s):Ĭounting only right digits of a float expression or counting the right-side digits of a decimal point.When we use -> Number(P)-–> Sore integer values only.Here this datatype is having following two arguments i.e. This data type is basically used for storing both integer & float format values. Note: When we use INT datatype on the column at the time of table creation then internally oracle server will convert it into “number” datatype with a maximum size is 38 digits. Lob Datatypes (Large Objects Datatypes).Oracle supports the following data types. Datatypes in Oracleĭatatype is an attribute that specifies what type of data is stored in a column.
