This is such a simple question but I haven't found an answer anywhere for 2 hours.
How do you use the MYSQL IF statment. No matter what I put in it doesn't work. In SQL Server this is a 5 second job.
Does it need to be within a procedure?
Can you use a SELECT within an IF statement?
Not really interested in the IF function here.
Thanks for any help.

Answer: MySQL IF() function can be used within a query, while the IF-ELSE conditional statement construct is supported to be used through FUNCTIONS or STORED PROCEDURES.
You can specify any condition using the WHERE clause. You can specify more than one condition using the AND or the OR operators. A WHERE clause can be used along with DELETE or UPDATE SQL command also to specify a condition.
Both IIF() and CASE resolve as expressions within a SQL statement and can only be used in well-defined places. The CASE expression cannot be used to control the flow of execution of Transact-SQL statements, statement blocks, user-defined functions, and stored procedures.
