Abstract
The invention enables transformation of an SQL statement of CHAR type to another SQL statement of another data type adequate for a database that is defined by a character string type other than CHAR type, thereby enabling to access the database using an SQL statement of CHAR type. At a call level interface (CLI driver), a literal such as a condition clause of an SQL SELECT statement that is included in an application program, a column value of an UPDATE statement or the like is passed to a function of the call level interface as a parameter. The call level interface examines a character type and a character code included in the passed literal, selects the most probable one of character string data types of a database to be accessed, modifies its access syntax in line with the selected data type and attempts to access the database. Accessing of the database is attempted while sequentially modifying the access syntax in the order of probability.
