To sort data by multiple columns in SQL, you can use the ORDER BY keyword in the SELECT statement. Specify the column names you want to sort by after the ORDER BY keyword, separated by commas. Add the ASC keyword for ascending order or the DESC keyword for descending order after each column name.
Select Custom Sort. Select Add Level. For Column, select the column you want to Sort by from the drop-down, and then select the second column you Then by want to sort. For example, Sort by Department and Then by Status.
You can specify multiple columns for ZORDER BY as a comma-separated list. However, the effectiveness of the locality drops with each extra column. Z-ordering on columns that do not have statistics collected on them would be ineffective and a waste of resources.
Luckily, SQL makes selecting multiple columns from a table easy. To select multiple columns from a table, simply separate the column names with commas!
To do this, we simply list the column names in the SELECT clause, separated by commas, followed by the table name.
You can also ORDER BY two or more columns, which creates a nested sort . The default is still ascending, and the column that is listed first in the ORDER BY clause takes precedence.
No, CASE is a function, and can only return a single value. I think you are going to have to duplicate your CASE logic. The other option would be to wrap the whole query with an IF and have two separate queries to return results.
You can also ORDER BY two or more columns, which creates a nested sort . The default is still ascending, and the column that is listed first in the ORDER BY clause takes precedence. The following query and Figure 3 and the corresponding query results show nested sorts.
To add several columns to a table in SQL Server, you can modify the standard command syntax in the following way: ALTER TABLE table_name ADD column_name1 data_type1, ADD column_name2 data_type2, ADD column_nameN data_typeN; You can add as many columns to a table as needed, and specify different data types for them all.
