If "min" or "max" is not specified, each defaults to 1. If "max"
is specified as "unlimited", then there is no specified maximum
number of elements, although the implementation will enforce some
- limit. After considering defaults, "min" must be at least 0,
- "max" must be at least 1, and "max" must be greater than or equal
- to "min".
+ limit. After considering defaults, "min" must be exactly 0 or
+ exactly 1, "max" must be at least 1, and "max" must be greater
+ than or equal to "min".
If "min" and "max" are both 1 and "value" is not specified, the
type is the scalar type specified by "key".
One of "<", "<=", "==", "!=", ">=", ">", "includes", "excludes".
+<mutation>
+
+ A 3-element JSON array of the form [<column>, <mutator>, <value>]
+ that represents a change to a column value.
+
+ Except as otherwise specified below, <value> must have the same
+ type as <column>.
+
+ The meaning depends on the type of <column>:
+
+ integer
+ real
+
+ <mutator> must be "+=", "-=", "*=", "/=" or (integer only)
+ "%=". The value of <column> is changed to the sum,
+ difference, product, quotient, or remainder, respectively,
+ of <column> and <value>.
+
+ boolean
+ string
+ uuid
+
+ No valid <mutator>s are currently defined for these types.
+
+ set
+
+ Any <mutator> valid for the set's element type may be
+ applied to the set, in which case the mutation is applied
+ to each member of the set individually. <value> must be a
+ scalar value of the same type as the set's element type.
+
+ If <mutator> is "insert", then each of the values in the
+ set in <value> is added to <column> if it is not already
+ present. The required type of <value> is slightly
+ relaxed, in that it may have fewer than the minimum number
+ of elements specified by the column's type.
+
+ If <mutator> is "delete", then each of the values in the
+ set in <value> is removed from <column> if it is present
+ there. The required type is slightly relaxed in that
+ <value> may have more or less than the maximum number of
+ elements specified by the column's type.
+
+ map
+
+ <mutator> must be "insert" or "delete".
+
+ If <mutator> is "insert", then each of the key-value pairs
+ in the map in <value> is added to <column> only if its key
+ is not already present. The required type of <value> is
+ slightly relaxed, in that it may have fewer than the
+ minimum number of elements specified by the column's type.
+
+ If <mutator> is "delete", then <value> may have the same
+ type as <column> (a map type) or it may be a set whose
+ element type is the same as <column>'s key type:
+
+ - If <value> is a map, the mutation deletes each
+ key-value pair in <column> whose key and value equal
+ one of the key-value pairs in <value>.
+
+ - If <value> is a set, the mutation deletes each
+ key-value pair in <column> whose key equals one of
+ the values in <value>.
+
+ For "delete", <value> may have any number of elements,
+ regardless of restrictions on the number of elements in
+ <column>.

Operations
----------
The "count" member of the result specifies the number of rows
that matched.
+mutate
+......
+
+Request object members:
+
+ "op": "mutate" required
+ "table": <table> required
+ "where": [<condition>*] required
+ "mutations": [<mutation>*] required
+
+Result object members:
+
+ "count": <integer>
+
+Semantics:
+
+ Mutates rows in a table.
+
+ Searches "table" for rows that match all the conditions specified
+ in "where". For each matching row, mutates its columns as
+ specified by each <mutation> in "mutations", in the order
+ specified.
+
+ The "_uuid" and "_version" columns of a table may not be directly
+ modified with this operation. Columns designated read-only in the
+ schema also may not be updated.
+
+ The "count" member of the result specifies the number of rows
+ that matched.
+
+Errors:
+
+ "error": "domain error"
+
+ The result of the mutation is not mathematically defined,
+ e.g. division by zero.
+
+ "error": "range error"
+
+ The result of the mutation is not representable within the
+ database's format, e.g. an integer result outside the range
+ INT64_MIN...INT64_MAX or a real result outside the range
+ -DBL_MAX...DBL_MAX.
+
+ "error": "constraint violation"
+
+ The mutation caused the column's value to violate a
+ constraint, e.g. it caused a column to have more or fewer
+ values than are allowed or an arithmetic operation caused a
+ set or map to have duplicate elements.
+
delete
......
Result object members:
- none
+ "uuid": <uuid>
Semantics:
The generated UUID is returned as the "uuid" member of the result.
-Result object members:
-
- "uuid": <uuid>
-
Errors:
"error": "duplicate uuid-name"
The same "uuid-name" appeared on an earlier "insert" or
"declare" operation within this transaction.
+
+comment
+.......
+
+
+Request object members:
+
+ "op": "comment" required
+ "comment": <string> required
+
+Result object members:
+
+ none
+
+Semantics:
+
+ Provides information to a database administrator on the purpose of
+ a transaction. The OVSDB server, for example, adds comments in
+ transactions that modify the database to the database journal.
