SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: ReferenceThe HCL OneDB™ Guide to SQL: Reference contains the reference information for the system catalog tables, data types, and environment variables of the HCL OneDB™ dialect of the SQL language, as implemented in HCL OneDB™. These topics also include information about the stores_demo, sales_demo, and superstore_demo databases that are included with HCL OneDB™.
Data typesEvery column in a table in a database is assigned a data type. The data type precisely defines the kinds of values that you can store in that column.
Description of Data Types
CHARACTER VARYING(m,r) data typeThe CHARACTER VARYING data type stores a string of letters, digits, and symbols of varying length, where m is the maximum size of the column (in bytes) and r is the minimum number of bytes reserved for that column.

CHARACTER VARYING(m,r) data type

The CHARACTER VARYING data type stores a string of letters, digits, and symbols of varying length, where m is the maximum size of the column (in bytes) and r is the minimum number of bytes reserved for that column.

The CHARACTER VARYING data type complies with ANSI/ISO standard for SQL; the non-ANSI VARCHAR data type supports the same functionality. For more information, see the description of the VARCHAR type in VARCHAR(m,r) data type.
