I have a program accessing Datacom tables using the SQL command below but it is taking a long time to run.
SELECT ID, NAME, CODE
WHERE NAME LIKE '%PROCESS%%%%%%%%%%%%%%';
How do I increase efficiency of this SQL SELECT using the LIKE operator?
Will creating a VIEW help?
Creating a view will not improve performance of the SQL SELECT.
The way to improve performance is to add a KEY for the column referred to in the in LIKE operator in the WHERE clause. In the example above, add a KEY on the NAME column.
