I can see that you have solved your problem, but to answer your original question:
REPLACE INTO
does not have a WHERE
clause.
The REPLACE INTO
syntax works exactly like INSERT INTO
except that any old rows with the same primary or unique key is automaticly deleted before the new row is inserted.
This means that instead of a WHERE
clause, you should add the primary key to the values beeing replaced to limit your update.
REPLACE INTO myTable (
myPrimaryKey,
myColumn1,
myColumn2
) VALUES (
100,
'value1',
'value2'
);
…will provide the same result as…
UPDATE myTable
SET myColumn1 = 'value1', myColumn2 = 'value2'
WHERE myPrimaryKey = 100;
…or more exactly:
DELETE FROM myTable WHERE myPrimaryKey = 100;
INSERT INTO myTable(
myPrimaryKey,
myColumn1,
myColumn2
) VALUES (
100,
'value1',
'value2'
);
