Update Statement Representation
The map below shows the structure of the update statement.
The sql-stmt, op, source and set-cols keys are required.
Source
...name... is anything convertible to a table name, usually a keyword.
Indexed-by
:indexed-by is anything convertible to an index name, usually a keyword.
Here’s how :indexed-by would be used…
{:source :tbl}
;; UPDATE tbl
{:source :tbl :indexed-by nil}
;; UPDATE tbl NOT INDEXED
{:source :tbl :indexed-by :ix}
;; UPDATE tbl INDEXED BY ixOp
The :op key can be anything convertible by to-sql-keywords.
Syntax will be provided for at least these update operations.
#{:update, :update-or-rollback, :update-or-abort, :update-or-replace
:update-or-fail, :update-or-ignore}Set-cols
The :set-cols value must be a map from column names to values.
The keys can be anything convertible to a column name (most commonly a keyword).
The values are expressions
Other Clauses
The remaining clauses have the same meaning as in select statements.
SQLite optionally allows ORDER BY, LIMIT and OFFSET clauses, but they may not be standard SQL.
