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.
INIT ClauseThe INIT clause of the ALTER FRAGMENT statement can define or modify the fragmentation strategy or the storage location of an existing table or an existing index.
FRAGMENT BY clause for indexesUse the FRAGMENT BY clause to redefine the storage distribution strategy of an index without redefining the index. The keywords FRAGMENT BY and PARTITION BY are synonyms in this context.
Detaching an Index from a Table-Fragmentation Strategy

Detaching an Index from a Table-Fragmentation Strategy

You can detach an index from a table-fragmentation strategy with the INIT clause of the ALTER FRAGMENT ON INDEX statement, so that an attached index becomes a detached index. This breaks any dependency of the index on the table fragmentation strategy. If the INIT clause specifies only IN dbspace or PARTITION fragment IN dbspace for a previously fragmented index, or if it specifies an index fragmentation strategy that differs from the storage option of the table, then the index becomes a detached index.
