SQL Server - LIKE Operator Works When Searching Partial String But Not Whole String -


i experiencing issue sql server database that, truthfully, i'm unsure how describe. therefore, try demonstrate it, best can.

i have table containing several rows value in [meter name] column 

electric meter #140002054 acct.2013147 house, south mall service &&parking lot

now, when run following query, result expect.

select distinct [meter name]  last_pm_export [meter name] 'electric meter #140002054 acct.2013147 house, south mall service%'

note using % wildcard, cutting off search pattern after word "service". following result.

expected result using partial string

again, expect. no problem.

now, observe happens when extend pattern include space comes after word "service".

select distinct [meter name]  last_pm_export [meter name] 'electric meter #140002054 acct.2013147 house, south mall service %'

unexpected result using partial string

as can see, query returns no results. have tried querying entire string, is, copied directly out of table.

select distinct [meter name]  last_pm_export [meter name] 'electric meter #140002054 acct.2013147 house, south mall service &&parking lot'

the result same query above. no results.

i cannot think of reason should happening. flies in face of how understand like operator work. i've consulted our in-office person, , agrees unusual.

again, know isn't description of problem, demonstration suffice. also, apologies not being able share table or database more fully, cannot reasons of confidentiality.

any assistance appreciated. thank you.

not answer, comment... please confirm, exact scenario of issue? can check out, both selects come right rows...

declare @mockup table([meter name] varchar(1000)); insert @mockup values('electric meter #140002054 acct.2013147 house, south mall service &&parking lot')                          ,('electric meter #140002054 acct.2013147 house, south mall service &&some other')                          ,('different');

--without blank

select * @mockup  [meter name] 'electric meter #140002054 acct.2013147 house, south mall service%';

--with blank

select * @mockup  [meter name] 'electric meter #140002054 acct.2013147 house, south mall service %';

might there more, reduced brevity? able change above mock-up in order make issue reproduceable?

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
