c# - INNER JOIN Syntax -

-

hows inner join syntax work? i'm new sql , dont understand how inner join works

querystring = @"select * wgcdoccab                serie ='1' , tipodoc ='fss' , contribuinte ='999999990' , numdoc =                 inner join  wgcnumeradores on wgcdoccab.numdoc = wgcnumerador.numero";

can tell me whats wrong, im sure syntax, im using c# visual studio 2013 , mysql

inner join used when pulling related data out of more 1 table. pointed out above, inner join comes before clause. try this:

querystring = @"select * wgcdoccab inner join  wgcnumeradores on wgcdoccab.numdoc = wgcnumerador.numero            serie ='1' , tipodoc ='fss' , contribuinte ='999999990'";

here explanation inner join:
