Parameter and keyword description - fetch statement, PL-SQL Programming

Assignment Help:

Parameter and Keyword Description:

cursor_name:

This identifies an explicit cursor formerly declared within the present scope.

cursor_variable_name:

These identify a PL/SQL cursor variable (or parameter) formerly declared within the present scope.

host_cursor_variable_name:

This identifies a cursor variable declared in the PL/SQL host atmosphere and passed to the PL/SQL as a bind variable. The host cursor variable datatype is well-suited with the return type of any PL/SQL cursor variable. The Host variables should be prefixed with a colon.

BULK COLLECT:

This clause instructs the SQL engine to bulk-bind the output collections before returning them to the PL/SQL engine. The SQL engine bulk-binds all the collections referenced in the INTO list. The corresponding columns should store scalar (not the composite) values.

variable_name:

This identifies a formerly declared scalar variable into which a column value is fetched. For each and every column value return by the query related with the cursor variable or cursor, there should be a analogous, type-compatible variable in the list.

record_name:

This identifies a user-defined or %ROWTYPE record into which the rows of values are fetched. For each and every column value return by the query is related with the cursor variable or cursor, there should be a analogous, type-compatible field in the record.

collection_name:

This identifies a declared collection into which the column values are bulk fetched. For each query select_item, there should be a analogous, type-compatible collection in the list.

host_array_name:

This identifies an array (stated in the PL/SQL host atmosphere and passed to the PL/SQL as a bind variable) into which the column values are bulk fetched. For each query select_item, there should be a corresponding, type-compatible array in the list. The Host arrays should be prefixed with a colon.
