Struct UpdateByKey 

pub struct UpdateByKey {
    pub table: TableId,
    pub keys: Vec<Value>,
    pub assignments: Assignments,
    pub filter: Option<Expr>,
    pub condition: Option<Expr>,
    pub returning: bool,
}

Updates one or more records identified by primary key.

Used by key-value drivers. SQL drivers receive an equivalent UPDATE statement via QuerySql instead. Supports conditional updates and optionally returns the updated records.

Examples

use toasty_core::driver::operation::{UpdateByKey, Operation};

let op = UpdateByKey {
    table: table_id,
    keys: vec![key_value],
    assignments: assignments,
    filter: None,
    condition: None,
    returning: true,
};
let operation: Operation = op.into();

Fields

table: TableId

The table to update.

keys: Vec<Value>

Primary key values identifying the records to update.

assignments: Assignments

Column assignments describing how to modify the records.

filter: Option<Expr>

Optional filter expression. When set, only records whose key is in keys and that match this filter are updated.

condition: Option<Expr>

Optional precondition that must hold for the update to be applied. Unlike filter, a failed condition typically causes an error rather than silently skipping the row.

returning: bool

When true, the driver returns the full record for each updated row in the ExecResponse.
