SQL select all but not if it is already in an other column
I know I know..
for sure one of the easier mysql statements. But somehow I can not figure out this.
I expect to see all distinct items of 'data_12' where 'kwroot' has 'straxx' in, and in the same row 'data_12' ist (not = 'kwsearched' in any existing row)
Result:
I see this statement works correct, but how can I tell him to check that "AND (data_12 NOT like kwsearched)"<== but also not in whole 'kwsearched'??
In order to speed up the query you should consider adding an index (or indexes).
What index you should add, depends on your data: you should start by indexing the most selective column(s) used in the where clause.
I would start with something like this:
You should consider indexing only subset of the data, if that subset is selective.
You should also consider the space needed for your indexes and their impact on the DML operations.
If the query is slow after indexing (some of) the columns in the where clause, post the output of the following statement:
I would verify the performance of both versions (in vs outer join) after creating the indexe(s).
Could you post also the output of the following command:
