更新查询给我一个 SQL 错误 (1064)

Question

I am trying to update a table in my database from another table. Here is my Syntax, but I can't seem to find any issues with it. I keep getting SQL Error (1064).

UPDATE customers b
SET customers.takerid = customer_update_2016.ot
FROM customer_update_2016 a, customers b
WHERE a.phone = b.phone && a.lname = b.lname

SQL Error (1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM customer_update_2016 a, customers b WHERE a.phone = b.phone & a.lname =b' at line 3

Solution:

UPDATE customers
INNER JOIN customer_update_2016
ON customers.phone = customer_update_2016.phone
AND customers.lname = customer_update_2016.lname 
SET customers.takerid = customer_update_2016.ot 

Answer 1

you have both mysql and sql-server
which one?

UPDATE customers
   SET customers.takerid = customer_update_2016.ot 
  FROM customers
  JOIN customer_update_2016
         on customers.phone =    customer_update_2016.phone 
        and customers.lname =    customer_update_2016.lname 
        and customers.takerid <> customer_update_2016.ot

Answer 2

Follow something like this always

UPDATE [table1_name] AS t1 
INNER JOIN [table2_name] AS t2 
ON t1.[column1_name] = t2.[column1_name] 
SET t1.[column2_name] = t2.[column2_name];

Answer 3

To solve your problem you should use JOIN, in my case I had to pass data from one table to another like you and this was the way that solved my problem, hope it help with yours and others.(I'm using MariaDB v10.4)

UPDATE 
table1
LEFT JOIN table2 AS tb2
ON tb2.fieldThatJoin = table1.fieldThatJoin//this part indicate the field that join them
SET 
table1.field1 = tb2.field1;
//if you want to update more than one field then do this
table1.field1 = tb2.field1,
table1.field2 = tb2.field2,
table1.field3 = tb2.field3;//remember to put the ';' at the end
