Application Note for QuNect ODBC for Quick Base

Scalar Numeric Functions Supported by QuNect ODBC for Quick Base

All numeric functions return values of data type SQL_FLOAT except for ABS, ROUND, TRUNCATE, SIGN, FLOOR, and CEILING, which return values of the same data type as the input parameters.

Arguments denoted as *numeric_exp* can be the name of a column, the result of another scalar function, or a *numeric-litera*l, where the underlying data type could be represented as SQL_NUMERIC, SQL_DECIMAL, SQL_TINYINT, SQL_SMALLINT, SQL_INTEGER, SQL_BIGINT, SQL_FLOAT, SQL_REAL, or SQL_DOUBLE.

Arguments denoted as *float_exp* can be the name of a column, the result of another scalar function, or a *numeric-literal*, where the underlying data type can be represented as SQL_FLOAT.

Arguments denoted as *integer_exp* can be the name of a column, the result of another scalar function, or a *numeric-literal*, where the underlying data type can be represented as SQL_TINYINT, SQL_SMALLINT, SQL_INTEGER, or SQL_BIGINT.

The CURRENT_DATE, CURRENT_TIME, and CURRENT_TIMESTAMP scalar functions have been added in ODBC 3.0 to align with SQL-92.

Function | Description |
---|---|

{fn ABS(numeric_exp)} |
Returns the absolute value of numeric_exp. |

{fn ACOS(float_exp)} |
Returns the arccosine of float_exp as an angle, expressed in radians. |

{fn ASIN(float_exp)} |
Returns the arcsine of float_exp as an angle, expressed in radians. |

{fn ATAN(float_exp)} |
Returns the arctangent of float_exp as an angle, expressed in radians. |

{fn ATAN2(float_exp1, float_exp2)} |
Returns the arctangent of the x and y coordinates, specified by float_exp1 and float_exp2, respectively, as an angle, expressed in radians. |

{fn CEILING(numeric_exp)} |
Returns the smallest integer greater than or equal to numeric_exp. The return value is of the same data type as the input parameter. |

{fn COS(float_exp)} |
Returns the cosine of float_exp, where float_exp is an angle expressed in radians. |

{fn COT(float_exp)} |
Returns the cotangent of float_exp, where float_exp is an angle expressed in radians. |

{fn DEGREES(numeric_exp)} |
Returns the number of degrees converted from numeric_exp radians. |

{fn EXP(float_exp)} |
Returns the exponential value of float_exp. |

{fn FLOOR(numeric_exp)} |
Returns the largest integer less than or equal to numeric_exp. The return value is of the same data type as the input parameter. |

{fn LOG(float_exp)} |
Returns the natural logarithm of float_exp. |

{fn LOG10(float_exp)} |
Returns the base 10 logarithm of float_exp. |

{fn MOD(integer_exp1, integer_exp2)} |
Returns the remainder (modulus) of integer_exp1 divided by integer_exp2. |

{fn PI( )} |
Returns the constant value of pi as a floating-point value. |

{fn POWER(numeric_exp, integer_exp)} |
Returns the value of numeric_exp to the power of integer_exp. |

{fn RADIANS(numeric_exp)} |
Returns the number of radians converted from numeric_exp degrees. |

{fn RAND([integer_exp])} |
Returns a random floating-point value using integer_exp as the optional seed value. |

{fn ROUND(numeric_exp, integer_exp)} |
Returns numeric_exp rounded to integer_exp places right of the decimal point. If integer_exp is negative, numeric_exp is rounded to |integer_exp| places to the left of the decimal point. |

{fn SIGN(numeric_exp)} |
Returns an indicator of the sign of numeric_exp. If numeric_exp is less than zero, –1 is returned. If numeric_exp equals zero, 0 is returned. If numeric_exp is greater than zero, 1 is returned. |

{fn SIN(float_exp)} |
Returns the sine of float_exp, where float_exp is an angle expressed in radians. |

{fn SQRT(float_exp)} |
Returns the square root of float_exp. |

{fn TAN(float_exp)} |
Returns the tangent of float_exp, where float_exp is an angle expressed in radians. |

{fn TRUNCATE(numeric_exp, integer_exp)} |
Returns numeric_exp truncated to integer_exp places right of the decimal point. If integer_exp is negative, numeric_exp is truncated to |integer_exp| places to the left of the decimal point. |
