*DEFAULT-STRING-LENGTH* — Default length of SQL strings.
Variable
If a slot of a class defined by def-view-class is of the type string or varchar and does not have a length specified, then the value of this variable is used as SQL length.
(let ((*default-string-length* 80)) (def-view-class s80 () ((a :type string) (b :type (string 80)) (c :type varchar)))) => #<Standard-Db-Class S80 {480A431D}> (create-view-from-class 's80) => (table-exists-p [s80]) => T
The above code causes a SQL table to be created with the SQL command
CREATE TABLE (A VARCHAR(80), B CHAR(80), C VARCHAR(80))
