Update statistics table (IDX_Table_ColumnName) with sample 100 percent
I clearly set 100%
In statistics sampling lines also is right, but I have hundreds of thousands of data, he is 4 line statistics,
I then set to 90% update
This time he has many lines of statistical information,
The database is 2014, why is this case ah.. How to avoid
