Fields§
§names: Vec<Ident>
The name(s) being declared. Example: `DECLARE a, b, c DEFAULT 42;
data_type: Option<DataType>
Data-type assigned to the declared variable. Example: `DECLARE x INT64 DEFAULT 42;
assignment: Option<DeclareAssignment>
Expression being assigned to the declared variable.
declare_type: Option<DeclareType>
Represents the type of the declared variable.
binary: Option<bool>
Causes the cursor to return data in binary rather than in text format.
sensitive: Option<bool>
None = Not specified Some(true) = INSENSITIVE Some(false) = ASENSITIVE
scroll: Option<bool>
None = Not specified Some(true) = SCROLL Some(false) = NO SCROLL
hold: Option<bool>
None = Not specified Some(true) = WITH HOLD, specifies that the cursor can continue to be used after the transaction that created it successfully commits Some(false) = WITHOUT HOLD, specifies that the cursor cannot be used outside of the transaction that created it
for_query: Option<Box<Query>>
FOR <query>
clause in a CURSOR declaration.
