SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: SyntaxThe HCL OneDB™ Guide to SQL: Syntax describes the syntax of the statements, data types, expressions, operators, and built-in functions of the HCL OneDB™ dialect of the SQL language.
Data types and expressionsThese topics describe the data types and expressions that HCL OneDB™supports.

Function Expressions
Exponential and Logarithmic Functions Exponential and logarithmic functions take at least one argument and return a FLOAT data type.
EXP FunctionThe EXP function returns the exponent of a numeric expression.

EXP Function

The EXP function returns the exponent of a numeric expression.

The following example returns the exponent of 3 for each row of the angles table:

SELECT EXP(3) FROM angles;

For this function, the base is always e, the base of natural logarithms, as the following example shows:

e=exp(1)=2.718281828459

When you want to use the base of natural logarithms as the base value, use the EXP function. If you want to specify a particular value to raise to a specific power, see the POW Function.
