![]() Variables meant to store only time values are assigned the time data type. Its variable length is binary data types.Ĭode: # create table bin_test (id bytea, dept_no bytea, salary bytea) PostgreSQL binary data types allow the storage of binary string in PostgreSQL. In these data types, we can store n number of characters.įor example, if we write varchar(9), it means that the variable will only be able to hold the maximum of nice characters.Ĭode: # create table char_test (first_name char(10), middle_name varchar(20), last_name text) Varchar(n) Data Type: Varchar data type with some number written along with it denotes that it can store or hold only the number of characters written next to it. In this data type, character strings with an unlimited number of records are referred to as text data. PostgreSQL refers to this as a variable-length character string. In all the cases where the length of the text that has to be stored is unknown, one can use the text data type. Text Data Type: The variable with data type as the text can store the long string values. The variable storing the char values occupies very little space of the storage. If the user tries to put more than one character in this, it will lead to an error. In this, there are mainly three distinct character data types available.Ĭhar Data Type: The char data type stores a single character value and is typically preferred when only a single character needs to be stored. Monetary data types in PostgreSQL stores the current amount with a fractional fixed precision number. ![]() Real: It is a 4-byte floating point no in PostgreSQL data types.Ĭode: # create table num_test1 (id real, number numeric, salary float) Numeric p and s are the exact numbers in numeric data types. ![]() Numeric: This is a real number data type in PostgreSQL. It is also called double-precision data types. Range if floating point is at least n and a maximum of 8 bytes. The range of big integer is -9223372036854775808 to 9223372036854775807Ĭode: # create table num_test (id smallint, number int, salary bigint) įloating-point numbers mainly divide into three types are as follows:įloat: This is floating point number precision in PostgreSQL.
