The
exclude_column is a column name. This is the syntax of
exclude_column_range:
'start_column:end_column' [, '-exclude_in-range_column' ]
The range includes its endpoints.
The
start_column and
end_column can be:
- Column names (for example, 'column1:column2')
Column names must contain only letters in the English alphabet, digits, and special characters. If a column name includes any special characters, surround the column name with double quotation marks. For example, if the column name is a*b, specify it as "a*b". A column name cannot contain a double quotation mark.
- Nonnegative integers that represent the indexes of columns in the table (for example, '[0:4]')
The first column has index 0; therefore, '[0:4]' specifies the first five columns in the table.
- Empty. For example:
-
'[:4]' specifies all columns up to and including the column with index 4.
-
'[4:]' specifies the column with index 4 and all columns after it.
-
'[:]' specifies all columns in the table.
The exclude_in-range_column is a column in the specified range, represented by either its name or its index (for example, '[0:99]', '-[50]', '-column10' specifies the columns with indexes 0 through 99, except the column with index 50 and column10).
Column ranges cannot overlap, and cannot include any specified exclude_column.
