Greater than or equal to the operator a. Operator ‘<.’ This operator compares the given expression and returns TRUE if the first operand is less than the second operand in the expression, or else it returns FALSE. b. Operator ‘>.’ This operator compares the given expression and returns...
In PostgreSQL, comparison operators like greater than “>” and greater than or equal to “>=” can be used with the “CURRENT_DATE” function to get a date greater than or equal to today. Some other built-in date functions likeNOW(),CURRENT_TIMESTAMP, andLOCALTIMESTAMPcan also be used...
If a value to be compared is greater than the largest value returned by the sub-query result, then the expression column > ALL (subquery) evaluates to true. If a value to be compared is greater than or equal to the largest value returned by the sub-query result, then the expression col...
This PostgreSQL tutorial explains how to use the PostgreSQL ceil function with syntax and examples. The PostgreSQL ceil function returns the smallest integer value that is greater than or equal to a number.
