Enum HandlerCondition 

pub enum HandlerCondition {
    SqlState {
        value_keyword: bool,
        sqlstate: Literal,
        meta: Meta,
    },
    ErrorCode {
        code: Literal,

        name: Ident,
        meta: Meta,
    },

    },
    NotFound {
        meta: Meta,
    },
    SqlException {
        meta: Meta,
    },
}

One condition in a DECLARE … HANDLER FOR <condition> [, …] list.

A superset of ConditionValue: a handler additionally catches a condition name declared earlier in the block and the three general condition classes.

Variants

SqlState

SQLSTATE [VALUE] '<sqlstate>' — a SQLSTATE string constant.

Fields

value_keyword: bool

Whether the optional VALUE noise keyword was written (fidelity tag).

sqlstate: Literal

The SQLSTATE string literal.

meta: Meta

Source location and node identity.

ErrorCode

A bare MySQL error-code integer (e.g. 1051).

Fields

code: Literal

The error-code integer literal.

meta: Meta

Source location and node identity.

ConditionName

A condition name declared earlier in the block (DECLARE … CONDITION).

Fields

name: Ident

The referenced condition name.

meta: Meta

Source location and node identity.

SqlWarning

SQLWARNING — the class of SQLSTATE values beginning 01.

Fields

meta: Meta

Source location and node identity.

NotFound

NOT FOUND — the class of SQLSTATE values beginning 02 (cursor exhaustion).

Fields

meta: Meta

Source location and node identity.

SqlException

SQLEXCEPTION — every remaining SQLSTATE class.

Fields

meta: Meta

Source location and node identity.

Trait Implementations
