DBIF_RSQL_SQL_ERROR — DBIF_RSQL_SQL_ERROR runtime error

DBIF_RSQL_SQL_ERROR belongs to the DBIF_RSQL exception family raised by the ABAP database interface whenever it passes a statement to the database layer and gets back a return code it cannot classify more precisely. Unlike DBIF_RSQL_TABLE_UNKNOWN or DBIF_RSQL_INVALID_REQUEST, which point at something wrong on the ABAP or dictionary side, SQL_ERROR is the catch-all for faults the database itself reports: a rejected statement, a failed commit, an aborted transaction, a resource limit hit inside the DBMS. The ABAP stack trace in the dump tells which program and which Open SQL statement triggered the call, but the decisive information is the native database error text embedded in the dump, which carries the vendor-specific code and message. Reading the ABAP side alone without that native text is reading half the dump.

If the native error text points at space exhaustion, this is a Basis action: extend the tablespace, datafile, or storage volume, and no ABAP change or transport is needed, though a permanent fix may require adjusting auto-extend settings or archiving. If the cause is a deadlock, functional and ABAP teams need to review the locking sequence in the offending program and any concurrent process it collides with; a genuine fix usually means reordering database access or introducing an SAP enqueue lock ahead of the database write, which requires a code change and a transport. If the cause is connection loss, Basis investigates the database and network layer; no code fix applies unless the program needs better commit-and-retry logic around long-running statements, which again is a change request. Privilege gaps are corrected by granting the missing authorization at database schema level, a Basis task with no transport involved. Data-value rejections point back to the ABAP data model or an inbound interface feeding oversized or malformed values, and the fix belongs to the ABAP or interface team as a proper transport. Corruption cases go to Basis/DBA for index rebuild or table repair, sometimes with a system downtime window.

The reflex is to wrap the failing Open SQL statement in a TRY CATCH block for the database interface exception class and swallow it, or to restart the work process or the whole instance and consider the incident closed once the dump stops recurring for a while. Both hide the symptom. Catching the exception without inspecting the native error text turns a database-level failure, often data loss or a partial commit, into a silently ignored error, which is worse than the dump. Restarting work processes clears the immediate condition (locked session, exhausted connection) but the space, deadlock, or privilege problem that caused it is untouched and will resurface, usually at a worse moment.

Set proactive alerting on tablespace and file system usage thresholds well below the point where the database has to reject an extend request, and review auto-growth settings on all production databases. Run regular deadlock graph review during peak batch windows and correct known lock-order conflicts in custom code before they escalate. Enforce a code standard that any program performing bulk inserts or updates validates value length and range against the dictionary before sending them to the database, and that long-running statements commit in controlled packages rather than one oversized transaction.

Split ownership: Basis owns database space, connectivity, privileges, and corruption; ABAP owns query design, locking sequence in custom code, and data value handling. The handover note should carry the native database error code and text from the dump, the table and statement identified in the call stack, the timestamp, whether the failure is isolated or repeating, and which side (space, lock, connection, privilege, data) the native text points to.

Sibling exceptions in the same database interface family include DBIF_RSQL_INVALID_CURSOR, DBIF_RSQL_TABLE_UNKNOWN, and DBIF_RSQL_INVALID_REQUEST, all raised by the same layer for more specific fault categories. SAPSQL_ARRAY_INSERT_DUPREC covers the narrower case of a duplicate-key violation on a mass insert, which can otherwise surface as a generic SQL error on some database platforms. TIME_OUT is worth checking when the failing statement was long-running before the database killed it.
