Syntax

dynamic_returning_clause ::=

into_clause ::=

Semantics

static_returning_clause

column

Expression whose value is the name of a column of a database table.

into_clause

Specifies the variables or record in which to store the column values that the statement returns.

Restriction on into_clause Use into_clause in dynamic_returning_clause if and only if dynamic_sql_stmt (which appears in "EXECUTE IMMEDIATE Statement") returns a single row.

record

The name of a record variable in which to store the row that the statement returns. For each select_item in the statement, the record must have a corresponding, type-compatible field.

variable

Either the name of a scalar variable in which to store a column that the statement returns or the name of a host cursor variable that is declared in a PL/SQL host environment and passed to PL/SQL as a bind variable. Each select_item in the statement must have a corresponding, type-compatible variable. The data type of a host cursor variable is compatible with the return type of any PL/SQL cursor variable.

Restriction on variable variable cannot have the data type BOOLEAN.

bulk_collect_into_clause

Specifies one or more existing collections or host arrays in which to store the rows that the statement returns. For each select_item in the statement, bulk_collect_into_clause must have a corresponding, type-compatible collection or host_array.

For the reason to use this clause, see "Bulk SQL and Bulk Binding".

Restrictions on bulk_collect_into_clause 

• Use the bulk_collect_into_clause clause in dynamic_returning_clause if and only if dynamic_sql_stmt (which appears in "EXECUTE IMMEDIATE Statement") can return multiple rows.

• You cannot use bulk_collect_into_clause in client programs.

• When the statement that includes bulk_collect_into_clause requires implicit data type conversions, bulk_collect_into_clause can have only one collection or host_array.

collection

Name of a collection variable in which to store the rows that the statement returns.

Restrictions on collection 

• collection cannot be the name of an associative array that is indexed by a string.

• When the statement requires implicit data type conversions, collection cannot be the name of a collection of a composite type.

:host_array

Name of an array declared in a PL/SQL host environment and passed to PL/SQL as a bind variable. Do not put space between the colon (:) and host_array.
