The typed statement with its host variables resolved and each OPEN given its DECLARE’s inputs.

Variants

Query

Fields

inputs: Vec<HostPlace<P>>

into: Vec<HostPlace<P>>

Change

Fields

delete: bool

inputs: Vec<HostPlace<P>>

current_of: Option<S>

Open

Fields

cursor: S

inputs: Vec<HostPlace<P>>

Fetch

Fields

cursor: S

into: Vec<HostPlace<P>>

Close

Fields

cursor: S

Commit

Rollback

Prepare

PREPARE of the statement name from the statement string in source, which must be one varying-length character or graphic string.

Fields

name: S

source: Vec<HostPlace<P>>

ExecuteImmediate

Fields

source: Vec<HostPlace<P>>

Execute

EXECUTE of a prepared statement, inputs replacing its parameter markers.

Fields

name: S

inputs: Vec<HostPlace<P>>

OpenPrepared

OPEN of a cursor declared for the prepared statement statement.

Fields

cursor: S

statement: S

inputs: Vec<HostPlace<P>>

Declaration

WHENEVER, DECLARE CURSOR, INCLUDE and the other declarations: no op.

Unsupported(S)

Abends EXEC, naming it, when reached.

Connect

CONNECT or SET CONNECTION: the host variable naming the location, if any, goes to the input trace, then the statement abends EXEC as an unsupported one does.

Fields

what: S

location: Vec<HostPlace<P>>
