Operator |
Description |
- Arg1 |
Negates the argument. The argument and the result are of type real. |
Arg1 + Arg2 |
Adds the two arguments. See operator & for string concatenation. |
Arg1 – Arg2 |
Subtracts Arg2 from Arg1. |
Arg1 * Arg2 |
Multiplies the two arguments. The arguments and the result are of type real or decimal. |
Arg1 / Arg2 |
Divides Arg1 by Arg2. The arguments and the result are of type real or decimal. Division by zero results in an invalid value.
Examples: |
Arg1 & Arg2 |
Appends Arg2 to the end of Arg1. The arguments can be of any type, but are converted to strings. The result is of type string. See also function Concatenate.
Examples: |
Arg1 % Arg2 |
Returns the remainder of the division of Arg1 by Arg2. The arguments and the result are of type real or decimal. Invalid values are propagated to the result column.
Example: 3.5 % 2.5 → 1.00 |
Arg1^Arg2 |
Returns Arg1 raised to the Arg2 power.
Example: 2.5^3 [Value Column]^2 |
Arg1 < Arg2 |
Operator which can be a part of an IF or a CASE statement. Returns true if Arg1 is less than Arg2. The arguments can be of any type, but must both be of the same type. The result is of type boolean. If any argument is invalid, the result is invalid. The function is defined for comparing normal numbers to each other. Other combinations result in invalid values.
Examples: If( 1 < 2, "true", "false" ) → true Case when 2 < 1 then "true" else
"false" end → false |
Arg1 > Arg2 |
Operator which can be a part of an IF or a CASE statement. Returns true if Arg1 is greater than Arg2. The arguments are of type real and the result is of type boolean. See operator < for the definition of valid arguments. |
Arg1 <= Arg2 |
Operator which can be a part of an IF or a CASE statement. Returns true if Arg1 is less than or equal to Arg2. The arguments are of type real and the result is of type boolean. See operator < for the definition of valid arguments. |
Arg1 >= Arg2 |
Operator which can be a part of an IF or a CASE statement. Returns true if Arg1 is greater than or equal to Arg2. The arguments are of type real and the result is of type boolean. See operator < for the definition of valid arguments. |
Arg1 = Arg2 |
Operator which can be a part of an IF or a CASE statement. Returns true if Arg1 is equal to Arg2. The arguments can be of any type, but must both be of the same type. The result is of type boolean. If any argument is null, the result is null. For arguments of type real, see operator < for the definition of valid arguments.
Examples: If(1 = 2, "true", "false" ) → false Case when 2 = 2 then "true" else "false" end → true If("Hello" = "hello",
"true", "false" ) →
false |
Arg1 <> Arg2 |
Operator which can be part of an 'IF' or a 'CASE' statement. Returns true if Arg1 is not equal to Arg2. The arguments can be of any type, but must both be of the same type. The result is of type boolean. If any argument is invalid, the result is invalid. For arguments of type real, see operator < for the definition of valid arguments. |
Arg1 ~= Arg2
|
Operator which can be part of an 'IF' or a 'CASE' statement. The arguments can be of any type, but will be treated as string columns. Returns true if the Arg2 regular expression string matches the Arg1 string.
Some characters, like for instance the backslash character "\", need to be escaped to work when using calculated columns. See literature about regular expression language elements, e.g., on MSDN, for more information.
Examples: If( "aab" ~= "a+" , "true", "false" ) → true Case when "aba" ~= ".a+$" then "true" else "false" end → true |
And(Arg1, ...) |
Operator which can be part of an 'If' or 'Case' statement. It has two boolean expressions as arguments and returns true if both expressions are true.
Examples: If( 1 < 2 and 2 < 3, "true", "false" ) Case when false and true then "true" else "false" end |
Not(Arg1) |
Operator which can be part of an 'If' or 'Case' statement. It negates the boolean expression given as argument.
Examples: If( not 1 < 2, "true", "false" ) Case when not true then "true" else "false" end |
Or(Arg1, ...) |
Operator which can be part of an 'If' or 'Case' statement. It has two boolean expressions as arguments and returns true if one of the expressions is true.
Examples: If( 1 < 2 or 2 < 3, "true", "false" ) Case when false or true then "true" else "false" end |
Xor(Arg1, ...) |
Can be part of an 'If' or 'Case' statement. It has two boolean expressions as arguments and returns true if exactly one of the expressions is true.
Examples: If(1 < 2 xor 2 < 3, true, false) Case when [A]>10 xor [B]>5 then 1 else 0 end |
