handle-options A request handle, a transaction handle, or both. REQUEST_HANDLE var The REQUEST_HANDLE keyword followed by a host language variable. A request handle identifies a compiled Oracle Rdb request. If you do not supply a request handle explicitly, RDML associates a unique request handle for the compiled request. TRANSACTION_HANDLE The TRANSACTION_HANDLE keyword followed by var a host language variable. A transaction handle identifies a transaction. If you do not supply a transaction handle explicitly, RDML uses the default transaction handle. context-var A context variable. A temporary name that you associate with a relation. You define a context variable in a relation clause. For more information see the entry on Context Variables. db-handle Database handle. A host variable used to refer to a specific database you have invoked. For more information see the entry on the Database Handle clause. relation-name The name of a relation in the database. on-error The ON ERROR clause. The first occurrence specifies host language or RDML statement(s) to be performed if an error occurs during the STORE operation. The second occurrence specifies host language or RDML statement(s) to be performed if an error occurs during the GET operation. For more information see the entry on ON ERROR. statement Any valid RDML or host language statement, except the GET statement, to be executed during the STORE operation. Use a semicolon (;) at the end of each RDML, Pascal, or C statement. get-item The GET statement includes an assignment statement specifying a host variable and a database value. The database value is assigned to the host variable from the Oracle Rdb value expression or statistical expression. Note that the GET statement must be the last statement to appear before the END_STORE statement. host-var A valid variable name declared in the host program. value-expr A valid RDML value expression. The value expression can include the "<context- variable>.RDB$DB_KEY" expression. record-descr A valid host language record descriptor that contains an entry for each field in fields of the relation. Each field of the record descriptor must match exactly the field names and data types of the fields in the Oracle Rdb relation referenced by the context variable. statistical-expr A statistical expression; calculates values based on a value expression for every record in the record stream.
