There is no MERGE statement in MySQL, so if you try to use it, an error will occur.

If you want to merge data from two tables in MySQL, you can achieve this by using the INSERT INTO SELECT statement. This statement will select data from one table and insert it into another table. Here is an example code:

INSERT INTO target_table (column1, column2, column3)
SELECT column1, column2, column3
FROM source_table
WHERE condition;

The target_table is the table where the data will be loaded, the source_table is where the data is coming from, column1, column2, and column3 are the names of the columns in the table, and condition is an optional filtering criteria.

Please ensure that the structure, column order, and data types of the target table match those of the source table to avoid any errors.
