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
TEXT data typeThe TEXT data type stores any kind of text data. It can contain both single-byte and multibyte characters that the locale supports. The term simple large object refers to an instance of a TEXT or BYTE data type.
Nonprintable Characters in TEXT Values

Nonprintable Characters in TEXT Values

TEXT columns typically store documents, program source files, and so on. In the default U.S. English locale, data objects of type TEXT can contain a combination of printable ASCII characters and the following control characters:

Tab (CTRL-I)
New line (CTRL-J)
New page (CTRL-L)

Both printable and nonprintable characters can be inserted in text columns. HCL OneDB™ products do not do any checking of data values that are inserted in a column of the TEXT data type. (Applications might have difficulty, however, in displaying TEXT values that include non-printable characters.) For detailed information about entering and displaying nonprintable characters, see Nonprintable Characters with CHAR.
