The query below lists all columns with string and binary data types.
Query
select schema_name(t.schema_id) + '.' + t.name as [table],
c.column_id,
c.name as column_name,
type_name(user_type_id) as data_type,
max_length
from sys.columns c
join sys.tables t
on t.object_id = c.object_id
where type_name(user_type_id) in ('text', 'ntext',
'varchar', 'nvarchar', 'char', 'nchar',
'binary', 'varbinary', 'image')
order by [table],
c.column_id;

- column_id - column position in table
- column_name - name of the column
- data_type - type of data
- max_length - maximum length in bytes
Rows
- One row represents one column with a string or binary data type
- Scope of rows: all columns containing string and binary data types in the database (schema)
