fails if a database is not selected prior. The problem manifested itself when a user tried to create a routine that had non-fully-qualified identifiers in its bodies and there was no current database selected. This is a regression introduced by the fix for Bug 19022: The patch for Bug 19022 changes the code to always produce a warning if we can't resolve the current database in the parser. In this case this was not necessary, since even though the produced parsed tree was incorrect, we never re-use sphead that was obtained at first parsing of CREATE PROCEDURE. The sphead that is anyhow used is always obtained through db_load_routine, and there we change the current database to sphead->m_db before calling yyparse. The idea of the fix is to resolve the current database directly using lex->sphead->m_db member when parsing a stored routine body, when such is present. This patch removes the need to reset the current database when loading a trigger or routine definition into SP cache. The redundant code will be removed in 5.1. mysql-test/r/sp.result: Update test results (Bug#29050) mysql-test/r/trigger.result: Update results. mysql-test/t/sp.test: Add a test case for Bug#29050 mysql-test/t/trigger.test: Fix wrong behavior covered with tests. sql/sql_lex.cc: Implement st_lex::copy_db_to(). sql/sql_lex.h: Declare st_lex::copy_db_to(). sql/sql_parse.cc: Use st_lex::copy_db_to() in add_table_to_list, rather than THD::copy_db_to(). The former will use the database of the sphead, if we're parsing a stored routine, not the default database in THD. The default database is needed to initialize tables->db when the database part was not explicitly specified in the identifier. sql/sql_yacc.yy: Use st_lex::copy_db_to() in the parser, rather than THD::copy_db_to(). The former will use the database of the sphead, if we're parsing a stored routine, not the default database in THD. |
