Mysql update multiple where conditions

I was wondering if you can do an Update with multiple conditions like so:

UPDATE participantes SET confirmado = 1 WHERE id = 19 AND id = 20 AND id = 21;

participantes -> Table

confirmado -> field of the table participantes.

MySQL's AND clause will only work when ALL of the criteria are met. What you're looking for is OR. In the format that you provided:

UPDATE participantes SET confirmado = 1 WHERE id = 19 OR id = 20 OR id = 21;

Although, the above-noted IN (19, 20, 21) would be better for this specific use case.

Your original query was trying to look for a single row where id was simultaneously 19, 20, and 21, which would never happen.

To accomplish what you're describing, I would, instead, use the IN clause:

UPDATE participantes SET confirmado = 1 WHERE id IN(19, 20, 21);

How about this?

UPDATE participantes SET confirmado = 1 WHERE id >= 19 AND id != 50 AND id != 51;

In MySQL, you can use tuple comparison:

WHERE (TestId, TestSubId) IN ((10,25), (11,22))

That looks nice and succinct, although, as ypercubeᵀᴹ mentioned in a comment, it may not work well performance-wise.

However, given how the conditions are re-used in your UPDATE statement, you could also take a different approach altogether: represent the affected IDs and the new values as a derived table and use an update with a join:

UPDATE
    Tests AS old
    INNER JOIN
    (
        SELECT 10 AS TestId, 25 AS TestSubId, 1000 AS TestScore, 2000 AS TestScore2
        UNION ALL
        SELECT 11, 22, 1100, 2100
    ) AS new
    ON old.TestId = new.TestId AND old.TestSubId = new.TestSubId
SET
    old.TestScore  = new.TestScore,
    old.TestScore2 = new.TestScore2
;

This way the new derived table acts both as a filter for Tests and a supplier of new values for the update.

MySQL UPDATE Statement

Last update on August 19 2022 21:51:22 (UTC/GMT +8 hours)

UPDATE Table

The MySQL UPDATE statement is used to update columns of existing rows in a table with new values.

Version: 5.6

Syntax :

Single table:

UPDATE [LOW_PRIORITY] [IGNORE] table_reference 
      SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
      [WHERE where_condition]
      [ORDER BY ...]
      [LIMIT row_count]

Multiple tables:

UPDATE [LOW_PRIORITY] [IGNORE] table_references
      SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
      [WHERE where_condition]

Arguments

NameDescription
table_reference(s) Name of table(s) to be updated.
col_name1, col_name2, .. Name of column(s) to be updated.
expr1, expr2,... New value(s).


  • For a single table, the UPDATE statement updates columns of existing rows in the named table with new values. Specific columns can be modified using the SET clause by supplying new values for that column.
  • The WHERE clause can be used to specify the conditions those identify which rows to update. Without using WHERE clause, all rows are updated.
  • The ORDER BY clause is used to update the order that is already specified.
  • The LIMIT clause specifies a limit on the number of rows that can be updated.
  • For multiple tables, UPDATE updates row in each table named in table_references that satisfy the conditions. In this case, ORDER BY and LIMIT cannot be used.

The UPDATE statement supports the following modifiers:

  • LOW_PRIORITY: Using LOW_PRIORITY keyword, execution of the UPDATE is delayed until no other clients are reading from the table. This affects only storage engines that use only table-level locking (such as MyISAM, MEMORY, and MERGE).
  • IGNORE : Using IGNORE keyword, the update statement does not abort even if errors occur during the update. Rows for which duplicate-key conflicts occur are not updated. Rows for which columns are updated to values that would cause data conversion errors are updated to the closest valid values instead.

Following are some examples on MySQL update where we have used newpurchase as sample table.

Sample table: newpurchase

MySQL UPDATE column

MySQL UPDATE column can be used to update some specific columns. The following MySQL statement will update the 'receive_qty' column of newpurchase table with a new value 20.

UPDATE newpurchase SET receive_qty=20;

MySQL UPDATE with WHERE

MySQL UPDATE command can be used with WHERE clause to filter (against certain conditions) which rows will be updated. The following MySQL statement will update the 'receive_qty' column of newpurchase table with a new value 25 if the value of purch_price is more than 50.

UPDATE newpurchase 
SET receive_qty=25 
WHERE purch_price>50;

MySQL UPDATE using NULL

MySQL UPDATE command can be used to update a column value to NULL by setting column_name = NULL, where column_name is the name of the column to be updated. The following MySQL statement will update pub_lang column with NULL if purch_price is more than 50. In this statement, other columns are also updated with respective new values.

UPDATE newpurchase 	
SET receive_qty=20,pub_lang='Hindi',pub_lang=NULL 
WHERE purch_price>50;

MySQL UPDATE multiple columns

MySQL UPDATE command can be used to update multiple columns by specifying a comma separated list of column_name = new_value. Where column_name is the name of the column to be updated and new_value is the new value with which the column will be updated. The following MySQL statement will update receive_qty, pub_lang, and receive_dt columns with new values 20, Hindi and 2008-07-10 if purch_price is more than 50.

UPDATE newpurchase 
SET receive_qty=20,pub_lang='Hindi',receive_dt='2008-07-10' 
WHERE purch_price>50;

MySQL UPDATE with subqueries

Here in the following, we have discussed how to use MySQL UPDATE command with subqueries.

The following MySQL statement will update purch_price with purch_price multiplied by 5 if it satisfies the condition defined in the subquery started with SELECT wrapped within a pair of parenthesis.

The subquery retrieves only those cate_ids from purchase table if their corresponding receive_qty is more than 10.

UPDATE  newpurchase 
SET purch_price=purch_price*.05
WHERE cate_id IN(SELECT cate_id 
FROM purchase 
WHERE receive_qty>10);

Updating MySQL Table using PHP Script

You can update MySQL table data (using UPDATE command) through a PHP script. Within the script, PHP function MySQL_query() execute the SQL command. We have used a table called 'item' to apply the query:
Table Name : item Structure : item_code varchar(20), value int(11), quantity int(11) where item_code is the primary key. In the following rows of item table, 'value' column which is marked with red rectangle will be updated.

Mysql update multiple where conditions

PHP Script

 <?php
  $dbhost = 'localhost';
  $dbuser = 'root';
  $dbpass = '';
  $connec = MySQL_connect($dbhost, $dbuser, $dbpass);
  if(!$connec)
  {
  die('Could not connect: ' . MySQL_error());
  }
  $sql = "UPDATE item
  SET value = '112'
  WHERE item_code='item1'";
  MySQL_select_db('MySQL');
  $result = MySQL_query($sql, $connec);
  if(!$result)
  {
  die('Could not update data: ' . MySQL_error());
  }
  echo "Data successfully updated...";
  MySQL_close($connec);
  ?>

Multiple Updates in MySQL

Sample table: table1

Mysql update multiple where conditions

Problem

If you want to update the val1 with 5,8 and 7 for concerned id 1,3 and 4 and the other val1 will remain same and the val2 will be updated with 13 and 5 for the concerned id 2 and 4 and the other will remain same, the following update statement can be used by using IF and CASE.

Code:

UPDATE table1 SET val1= CASE id 
                          WHEN 1 THEN 5 
                          WHEN 3 THEN 8 
                          WHEN 4 THEN 7 
                          ELSE val1
                        END, 
                 val2= CASE id 
                          WHEN 2 THEN 13 
                          WHEN 4 THEN 5 
                          ELSE val2 
                        END
             WHERE id IN (1, 2, 3, 4);

If we want to update the book_price of the table book_mast by an increment of 5% and also update the purch_price and total_cost of puchase table by an increment of 5%, and this increment will affect only those rows in both book_mast and purchase table, which publishing language is English and book_id matching in both the tables, we can write the following code -

UPDATE book_mast,purchase
SET book_mast.book_price=book_mast.book_price+(book_mast.book_price*.05),
purchase.purch_price=purchase.purch_price+(purchase.purch_price*.05),
purchase.total_cost=receive_qty*(purchase.purch_price+(purchase.purch_price*.05))
WHERE book_mast.book_id=purchase.book_id
AND purchase.pub_lang="English";

After updating it is to be shown that, the highlighted rows have been effected in both the tables.

How do I UPDATE multiple values in MySQL?

MySQL UPDATE multiple columns MySQL UPDATE command can be used to update multiple columns by specifying a comma separated list of column_name = new_value. Where column_name is the name of the column to be updated and new_value is the new value with which the column will be updated.

How do you UPDATE a table with multiple conditions?

The SQL AND condition and OR condition can be combined to test for multiple conditions in a SELECT, INSERT, UPDATE, or DELETE statement. When combining these conditions, it is important to use parentheses so that the database knows what order to evaluate each condition.

How do you UPDATE multiple columns in SQL with different conditions?

To update multiple columns use the SET clause to specify additional columns. Just like with the single columns you specify a column and its new value, then another set of column and values. In this case each column is separated with a column.
