SQL query search for two strings

Question

I am trying to run a basic sql query where is search for one of two string:

1. "Nightly job up"
2. "Nightly job finished"

I have tried the where command but i getting an empty output. This is the problematic part:

      where execution_location = ('Nightly job up' or Nightly job 'finished');

Please assist, Thanks in advance.

Answer 1

Use IN(...) instead:

where execution_location in ('Nightly job up', 'Nightly job finished');

This is the way to compare multiple values in one clause.

Answer 2

对于MySQL或Transact-SQL，您的where字符串应为：

WHERE (execution_location = 'Nightly job up' OR execution_location = 'Nightly job finished');

Answer 3

Try:

WHERE execution_location IN ('Nightly job up, 'Nightly job finished');

or, if what you want is finding every string starting with Nightly job:

WHERE execution_location LIKE 'Nightly job%'

Answer 4

尝试

where execution_location in ('Nightly job up', 'Nightly job finished');

Answer 5

Your expression:

('Nightly job up' or 'Nightly job finished')

... is evaluated as a boolean expression, and results in 0 (or FALSE ) (because strings evaluate as FALSE ).

Therefore your final WHERE clause is equivalent to:

... WHERE execution_location = 0

The right syntax has already been provided by everyone else :)
