    DataConnector supports multiple data operations using different operations. The tables below describe following operators with examples:

    Arithmetic operators

    Operator Description Example
    + (Addition) Adds values on either side of the operator a + b will give 30
    - (Subtraction) Subtracts the right hand operand from the left hand operand a - b will give -10
    * (Multiplication) Multiplies values on either side of the operator a * b will give 200
    / (Division) Divides the left hand operand by the right hand operand  b / a will give 2
    % (Modulus) Divides the left hand operand by the right hand operand and returns the remainder b % a will give 0

    Comparison operators

    Operator Description Example
    = Checks if the values of two operands are equal or not, if yes then the condition becomes true. (a = b) is not true.
    != Checks if the values of two operands are equal or not, if the values are not equal, then the condition becomes true. (a != b) is true.
    <> Checks if the values of two operands are equal or not, if the values are not equal, then the condition becomes true. (a <> b) is true.
    > Checks if the values of the left operand is greater than the value of the right operand, if yes then the condition becomes true. (a > b) is not true.
    < Checks if the values of the left operand is less than the value of the right operand, if yes then the condition becomes true. (a < b) is true.
    >= Checks if the value of the left operand is greater than or equal to the value of the right operand, if yes then the condition becomes true. (a >= b) is not true.
    <= Checks if the value of the left operand is less than or equal to the value of the right operand, if yes then the condition becomes true. (a <= b) is true.

    Bitwise operators

    Operator Description Example
    &  Binary AND Operator copies a bit to the result, if it exists in both operands. (A & B) will give 12 which is 0000 1100
    | Binary OR Operator copies a bit, if it exists in either operand. (A | B) will give 61 which is 0011 1101
    ~ Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. (~A ) will give -61 which is 1100 0011 in 2's complement form due to a signed binary number
    << Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. A << 2 will give 240 which is 1111 0000
    >> Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. A >> 2 will give 15 which is 0000 1111

    Logical operators

    Operator Description
    AND The AND operator allows the existence of multiple conditions in an SQL statement's WHERE clause. 
    OR The OR operator is used to combine multiple conditions in an SQL statement's WHERE clause.
    EXISTS The EXISTS operator is used to search for the presence of a row in a specified table that meets certain criteria.
    IN The IN operator is used to compare a value to a list of literal values that have been specified.
    NOT IN The negation of IN operator which is used to compare a value to a list of literal values that have been specified.
    IS The IS operator work like =
    IS NOT The IS operator work like !=
    LIKE The LIKE operator is used to compare a value to similar values using wildcard operators.
    NOT LIKE The negation of LIKE operator which is used to compare a value to similar values using wildcard operators.
    BETWEEN The BETWEEN operator is used to search for values that are within a set of values, given the minimum value and the maximum value.
