The default value for p is 10. The default value for s is 0.
+ |
+
TINYINT |
+ Data type of a 1-byte signed integer with values from -128 to 127. |
+
SMALLINT |
+ Data type of a 2-byte signed integer with values from -32,768 to 32,767. |

+
BIGINT |
+ Data type of an 8-byte signed integer with values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. |
+
FLOAT |
+ Data type of a 4-byte single precision floating point number.+ Compared to the SQL standard, the type does not take parameters.
+ |
+
DOUBLE |
+ Data type of an 8-byte double precision floating point number. |
+
DATE |
+ Data type of a date consisting of year-month-day with values ranging from 0000-01-01 to 9999-12-31.+ Compared to the SQL standard, the range starts at year 0000.
+ |
+
TIME+ TIME(p)
+ |
+ Data type of a time without time zone consisting of hour:minute:second[.fractional] with up to nanosecond precision and values ranging from 00:00:00.000000000 to 23:59:59.999999999.+ The type can be declared using TIME(p) where p is the number of digits of fractional seconds (precision). p must have a value between 0 and 9 (both inclusive). If no precision is specified, p is equal to 0.
+ |
+
TIMESTAMP+ TIMESTAMP(p)
+ |
+ Data type of a timestamp without time zone consisting of year-month-day hour:minute:second[.fractional] with up to nanosecond precision and values ranging from 0000-01-01 00:00:00.000000000 to 9999-12-31 23:59:59.999999999.+ The type can be declared using TIMESTAMP(p) where p is the number of digits of fractional seconds (precision). p must have a value between 0 and 9 (both inclusive). If no precision is specified, p is equal to 6.
+ |
+
TIMESTAMP WITH TIME ZONE+ TIMESTAMP(p) WITH TIME ZONE
+ |
+ Data type of a timestamp with time zone consisting of year-month-day hour:minute:second[.fractional] zone with up to nanosecond precision and values ranging from 0000-01-01 00:00:00.000000000 +14:59 to 9999-12-31 23:59:59.999999999 -14:59.+ This type fills the gap between time zone free and time zone mandatory timestamp types by allowing the interpretation of UTC timestamps according to the configured session time zone. A conversion from and to int describes the number of seconds since epoch. A conversion from and to long describes the number of milliseconds since epoch.
+ |
+
ARRAY<t> |
+ Data type of an array of elements with same subtype.+ Compared to the SQL standard, the maximum cardinality of an array cannot be specified but is fixed at 2,147,483,647. Also, any valid type is supported as a subtype.+ The type can be declared using ARRAY<t> where t is the data type of the contained elements.
+ |
+
MAP<kt, vt> |
+ Data type of an associative array that maps keys (including NULL) to values (including NULL). A map cannot contain duplicate keys; each key can map to at most one value.+ There is no restriction of element types; it is the responsibility of the user to ensure uniqueness.+ The type can be declared using MAP<kt, vt> where kt is the data type of the key elements and vt is the data type of the value elements.
+ |
+
MULTISET<t> |
+ Data type of a multiset (=bag). Unlike a set, it allows for multiple instances for each of its elements with a common subtype. Each unique value (including NULL) is mapped to some multiplicity.+ There is no restriction of element types; it is the responsibility of the user to ensure uniqueness.+ The type can be declared using MULTISET<t> where t is the data type of the contained elements.
+ |
+
ROW<n0 t0, n1 t1, ...>+ ROW<n0 t0 'd0', n1 t1 'd1', ...>
+ |
+ Data type of a sequence of fields.+ A field consists of a field name, field type, and an optional description. The most specific type of a row of a table is a row type. In this case, each column of the row corresponds to the field of the row type that has the same ordinal position as the column.+ Compared to the SQL standard, an optional field description simplifies the handling with complex structures.+ A row type is similar to the STRUCT type known from other non-standard-compliant frameworks.+ The type can be declared using ROW<n0 t0 'd0', n1 t1 'd1', ...> where n is the unique name of a field, t is the logical type of a field, d is the description of a field.
