The execution of the above query statement gives the following output: For this, we will use the following query statement – SELECT CONCAT("EDUCBA", "IS A GREAT ", "PLATFORM ", "TO EXPAND ", "YOUR HORIZONS ", "OF LEARNING") AS "Final String" Now, we will concatenate the string values “EDUCBA”, “IS A GREAT “, “PLATFORM “, “TO EXPAND “, “YOUR HORIZONS” and “OF LEARNING” using the Concat function in MySQL. We can observe from the output that an error is raised, saying that an incorrect number of parameters were supplied to the Concat function.
