Insert ALL | OPERATORS in Oracle SQL - Day 13
In Oracle SQL, operators are symbols or keywords used to perform operations on data, compare values, and combine conditions in queries. Here is a short description of some commonly used operators in Oracle SQL:
1. Arithmetic Operators:
`+` (Addition): Adds two values.
`-` (Subtraction): Subtracts one value from another.
`*` (Multiplication): Multiplies two values.
`/` (Division): Divides one value by another.
`%` (Modulus): Returns the remainder of division.
2. Comparison Operators:
`=` (Equal to): Checks if two values are equal.
`!=` or `` (Not equal to): Checks if two values are not equal.
(Less than): Checks if the left operand is less than the right operand.
(Greater than): Checks if the left operand is greater than the right operand.
(Less than or equal to): Checks if the left operand is less than or equal to the right operand.
(Greater than or equal to): Checks if the left operand is greater than or equal to the right operand.
3. Logical Operators:
`AND`: Combines two conditions and returns true if both conditions are true.
`OR`: Combines two conditions and returns true if either condition is true.
`NOT`: Negates a condition and returns true if the condition is false.
4. String Operators:
`||` (Concatenation): Concatenates two strings.
`LIKE`: Compares a value to a pattern using wildcard characters (% and _).
`IN`: Checks if a value matches any value in a list.
`BETWEEN`: Checks if a value is within a range of values.
These are just a few examples of operators in Oracle SQL. There are additional operators available for specific purposes, such as aggregate functions, set operators, and others.
