The ROW specification (
row_spec) is a syntax element in a LOCK statement or an UNLOCK statement.Syntax
<row_spec> ::= ROW <table_name> KEY <key_spec>,...
| ROW <table_name> CURRENT OF <result_table_name>
Explanation
For tables defined without key columns, the implicit key column SYSKEY CHAR(8) BYTE can be used in a key specification.
If
CURRENT OF <result_table_name> is specified, the result table must have been specified with FOR UPDATE.
