What are the data types in SAP HANA?

SAP HANA Data Type. Precision p can range from 1 to 38. The scale s can range from 0 to p. If precision and scale are not specified, DECIMAL becomes a floating-point decimal number. It is a floating-point decimal number. The precision and scale should be within the range 1~16 for precision and -369~368 for scale, depending on the stored value.

Max integer length is between 1 and 5000. LARGEOBJECTS are used to store a large amount of data such as text documents and images. NCLOB − stores large UNICODE character object. BLOB − stores large amount of Binary data. CLOB − stores large amount of ASCII character data. TEXT − it enables text search features.

The SMALLDECIMAL data type is for a floating-point decimal number. For these values, the precision and scale vary within the range of 1 to 16 for precision and -369 to 368 for scale. The SMALLDECIMAL values are only supported in the column store.

The INTEGER data type stores a 32-bit signed integer. The minimum value is -2,147,483,648 and the maximum value is 2,147,483,647. The BIGINT data type stores a 64-bit signed integer. The minimum value is -9,223,372,036,854,775,808 and the maximum value is 9,223,372,036,854,775,807.

Undelimited Identifiers – Undelimited identifiers (table name, column name) must start with a letter and cannot contain any symbols other than a digit or an underscore ‘_’. Single Quotation Mark (‘ ‘) – It is used to delimit the string.

HH24 represents the hour from 0 to 24, MI represents the minute from 0 to 59, SS represents the second from 0 to 59. SECONDDATEThe SECONDDATEdata type consists of year, month, day, hour, minute and second information to represent a date with time value. The default format for the SECONDDATEdata type is ‘YYYY-MM-DD HH24:MI:SS’.

By leveraging C++11/14 implementation techniques and idioms, Hana boasts faster compilation times and runtime performance on par or better than previous metaprogramming libraries, while noticeably increasing the level of expressiveness in the process.
