Hello all,
Just wanted to know how many columns are preferable in table. At present we are
having nearly 50 - 60 columns in some of the tables. Is this ok or should we be
splitting the tables for normalization.
If we really need to split then how better would it be in terms of performance

OS that is being used. The more columns you have the larger the database
file will be. You should try to avoid having many empty columns in a
database design, even if you are using varchar instead of char. Try to

2) Is it just as fast with Mysql to access 10 fields in a table with 10
columns as it would be to access those same 10 fields among let's say 90
other fields in a 100 column table?
Are you certain that performance should be your primary concern here?

Two questions:
1) How many columns does MySQL support per table?
2) Is it just as fast with Mysql to access 10 fields in a table with 10
columns as it would be to access those same 10 fields among let's say 90
other fields in a 100 column table? Would speed only be reduced if I
pulled a query
