In SQL, operators are special symbols that perform operations on one or more expressions and return a result. Understanding these operators is essential for writing effective SQL queries.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Arithmetic operators are used to perform mathematical calculations.<\/p>\n\n\n\n
+<\/code>)<\/strong>: Adds two values.<\/li>\n\n\n\n- Subtraction (
-<\/code>)<\/strong>: Subtracts one value from another.<\/li>\n\n\n\n- Multiplication (
*<\/code>)<\/strong>: Multiplies two values.<\/li>\n\n\n\n- Division (
\/<\/code>)<\/strong>: Divides one value by another.<\/li>\n\n\n\n- Modulus (
%<\/code>)<\/strong>: Returns the remainder of a division operation.<\/li>\n<\/ul>\n\n\n\n<\/p>\n\n\n\n
SQL Bitwise Operators<\/h2>\n\n\n\n
Bitwise operators are used to perform operations on binary representations of integers. These operators are typically used for manipulating binary data.<\/p>\n\n\n\n
\n- AND (
&<\/code>)<\/strong>: Compares each bit of two integers and returns a bit set to 1 if both bits are 1.<\/li>\n\n\n\n- OR (
|<\/code>)<\/strong>: Compares each bit of two integers and returns a bit set to 1 if at least one of the bits is 1.<\/li>\n\n\n\n- XOR (
^<\/code>)<\/strong>: Compares each bit of two integers and returns a bit set to 1 if only one of the bits is 1.<\/li>\n\n\n\n- NOT (
~<\/code>)<\/strong>: Inverts all bits of an integer.<\/li>\n<\/ul>\n\n\n\n<\/p>\n\n\n\n
SQL Comparison Operators<\/h2>\n\n\n\n
Comparison operators are used to compare two values and return a boolean result (true or false).<\/p>\n\n\n\n
\n- Equal (
=<\/code>)<\/strong>: Checks if two values are equal.<\/li>\n\n\n\n- Not Equal (
!=<\/code> or <><\/code>)<\/strong>: Checks if two values are not equal.<\/li>\n\n\n\n- Greater Than (
><\/code>)<\/strong>: Checks if the left value is greater than the right value.<\/li>\n\n\n\n- Less Than (
<<\/code>)<\/strong>: Checks if the left value is less than the right value.<\/li>\n\n\n\n- Greater Than or Equal To (
>=<\/code>)<\/strong>: Checks if the left value is greater than or equal to the right value.<\/li>\n\n\n\n- Less Than or Equal To (
<=<\/code>)<\/strong>: Checks if the left value is less than or equal to the right value.<\/li>\n<\/ul>\n\n\n\n<\/p>\n\n\n\n
SQL Compound Operators<\/h2>\n\n\n\n
Compound operators are shorthand for performing an operation and assigning a value in one step. They are used to simplify statements.<\/p>\n\n\n\n
\n- Addition Assignment (
+=<\/code>)<\/strong>: Adds the right operand to the left operand and assigns the result to the left operand.<\/li>\n\n\n\n- Subtraction Assignment (
-=<\/code>)<\/strong>: Subtracts the right operand from the left operand and assigns the result to the left operand.<\/li>\n\n\n\n- Multiplication Assignment (
*=<\/code>)<\/strong>: Multiplies the left operand by the right operand and assigns the result to the left operand.<\/li>\n\n\n\n- Division Assignment (
\/=<\/code>)<\/strong>: Divides the left operand by the right operand and assigns the result to the left operand.<\/li>\n<\/ul>\n\n\n\n<\/p>\n\n\n\n
SQL Logical Operators<\/h2>\n\n\n\n
Logical operators are used to combine multiple conditions in a SQL statement.<\/p>\n\n\n\n
\n- AND<\/strong>: Returns true if both conditions are true.<\/li>\n\n\n\n
- OR<\/strong>: Returns true if at least one condition is true.<\/li>\n\n\n\n
- NOT<\/strong>: Reverses the result of a condition (true becomes false and vice versa).<\/li>\n<\/ul>\n\n\n\n
