public class QRYBLKCTL

extends STRING

implements CodePoints

Query Block Protocol Control (QRYBLKCTL) String controls the type of query block protocol used when a query is opened. When the parameter is specified in the OPNQRY command, it controls the query protocol used for the specific query being opened. When the parameter is specified in the BGNBND command, it controls the query protocols all queries in the package use unless the OPNQRY command overrides it. A database cursor is ambiguous if it is not declared for FETCH ONLY or UPDATE, not the target of a WHERE_CURRENT_OF clause on an SQL UPDATE or DELETE statement, and if the package has dynamic SQL capability. All other database cursors are certain. When the database cursor is certain and the qryblkctl parameter takes the value FIXROWPRC or LMTBLKPRC, then the protocols used are defined in the terms FIXROWPRC and LMTBLKPRC. The value FRCFIXROW means that the target SQLAM must use the fixed row query protocol for all database cursors (see FRCFIXROW)). The value FIXROWPRC means that the target SQLAM must use the fixed row query protocol for all queries that have ambiguous database cursors. The value LMTBLKPRC means that the target SQLAM must use the limited block query protocol for all queries that have ambiguous database cursors, except if the cursor is scrollable and has a sensitivity that requires FIXROWPRC.
