   • Oracle sql, update multiple rows using CASE

     Top Answer

     Answered Oct 25, 2017 · 2 votes

     Don't use case. Instead:

     UPDATE GRIDCOLUMNS SET TYPE = 6 WHERE Fieldname = 'AccountNum' AND ID IN (19337, 19339, 19380, 19419);-

     This is much more efficient. If you really need to use CASE, then you need an ELSE:

     UPDATE GRIDCOLUMNS SET TYPE = (CASE WHEN Fieldname = 'AccountNum' AND ID IN (19337, 19339, 19380, 19419) THEN 6 ELSE TYPE END);-

     Otherwise, the non-matching rows get set to NULL. But really, use the WHERE.

   • SQL UPDATE: Multiple columns in one statement or multiple single-column statements?

     Top Answer

     Answered Sep 13, 2012 · 6 votes

     This may vary with the particular implementation of any one database engine, but I'm going to cast my vote that a single update will generally be better performing than successive updates. The DB need only find the desired record once, update the relevant values, and be done with it.

     Now, given that there are plan caches, indexes, optimizers, and other elements at hand to make things smarter on the fly, it may well be that the multi-update version will nearly approach the performance of the former, but my expectation is that, even under the best of circumstances, the former will perform better.

   • Update multiple columns in SQL

     The "tiresome way" is standard SQL and how mainstream RDBMS do it.

     With a 100+ columns, you mostly likely have a design problem... also, there are mitigating methods in client tools (eg generation UPDATE statements) or by using ORMs

     Try this:

     UPDATE table1 SET a = t2.a, b = t2.b, .......FROM table2 t2WHERE table1.id = t2.id

     That should work in most SQL dialects, excluding Oracle.

     And yes - it's a lot of typing - it's the way SQL does this.
