SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: SyntaxThe HCL OneDB™ Guide to SQL: Syntax describes the syntax of the statements, data types, expressions, operators, and built-in functions of the HCL OneDB™ dialect of the SQL language.
SQL statementsThis chapter describes the syntax and semantics of SQL statements that are recognized by HCL OneDB™.
ALTER FRAGMENT statementUse the ALTER FRAGMENT statement to change the distribution strategy or the storage location of an existing table or index. This statement is an extension to the ANSI/ISO standard for the SQL language.
DETACH ClauseUse the DETACH clause of the ALTER FRAGMENT ON TABLE statement to detach a table fragment from a storage distribution scheme and place the contents into a new nonfragmented table.
Detach with BYTE and TEXT Columns

Detach with BYTE and TEXT Columns

If the DETACH clause specifies the first fragment of a table that includes simple large objects of data type BYTE or TEXT, the database server applies locks on the blobspaces of every fragment of the table. To detach any other fragment of the table locks only the blobspaces of the specified fragment, rather than the blobspaces of all fragments, so fewer locks are required if the fragment is not the first.
