SQL query to update table only if all values for column match
I'm playing around with queries and tables and have a table that looks like this.
Name | Job | Status =============================== Test1 | Completed | Pending Test1 | 50% | Pending Test2 | Completed | Pending Test2 | Completed | Pending Test2 | Completed | Pending
Is there a query I can use that will look at the name and job column, and if the job column is "completed" for all matching names, update the status column to say "completed"?
To clarify, in the above example, all the "Test2" jobs are marked as completed, so I would like the status to also say completed - but only if ALL the Test2 jobs say completed.
Here is one possible solution for SQL Server:
UPDATE yourTable t1 SET Status = 'Completed' WHERE Job = 'Completed' AND NOT EXISTS (SELECT 1 FROM yourTable t2 WHERE t1.Name = t2.Name AND (t2.Job <> 'Completed' OR t2.Job IS NULL));
SQL UPDATE Statement - Updating Data in a Table, How do you update a column with different values in SQL? Another approach is to use a joined update query. The exact SQL that is required depends on which database system you're using, but here's an example for SQL Server: update tblA set Fld1 = B.Fld1 from tblA A inner join tblB B on A.Fld2 = B.Fld2 Note that only rows that have a match are updated.
UPDATE Table1 SET Status = 'Completed' WHERE Name IN ( SELECT Name FROM Table1 GROUP BY Name HAVING COUNT(*) = SUM(CASE WHEN Job='Completed' THEN 1 ELSE 0 END) )
The inner select finds the names with all Job values set to Completed, and the update just updates Status of the rows with the found names.
How to UPDATE from SELECT in SQL Server, How do you update a column based on data from another table? Conditional Update To do a conditional update depending on whether the current value of a column matches the condition, you can add a WHERE clause which specifies this. The database will first find rows which match the WHERE clause and then only perform updates on those rows. UPDATE table SET col = new_value WHERE col = old_value;
UPDATE Table_Name SET Status = 'Completed' WHERE Name = 'Completed' AND Job = 'Completed'
Is there a way to SELECT and UPDATE rows at the same time , and inserting records as necessary for the two to match. First, specify the table name that you want to change data in the UPDATE clause. Second, assign a new value for the column that you want to update. In case you want to update data in multiple columns, each column = value pair is separated by a comma (,). Third, specify which rows you want to update in the WHERE clause.

UPDATE yourTable SET Status = 'Completed' WHERE Job = 'Completed' AND Name not in (select Name from yourTable where Job<>'Completed')

SQL UPDATE Statement, Column values may be updated either with constants, identifiers to other data sets, or expressions. This is only relevant if table is inherited by any other tables. The WHERE clause constrains any modifications to rows that match the criteria If the WHERE clause is omitted, an UPDATE statement will modify each of the Takes all records of the Pupils table and the ones of the Marks table; And filters them, keeping only the records where the Pupil Name matches the name on the Marks table. The technical name is a Join. This is often referred to as a "Multiplication", because the number of records in the intermediary table (before filtering) is a multiplication
