Description
While MDEV-28998 was previously fixed, the following testcase:
--let $SOCKET= `SELECT @@global.socket`
|
INSTALL PLUGIN Spider SONAME 'ha_spider.so'; |
SET spider_same_server_link=ON; |
CREATE USER spider@localhost IDENTIFIED BY 'pwd'; |
GRANT ALL ON test.* TO spider@localhost; |
eval CREATE SERVER srv FOREIGN DATA WRAPPER MYSQL OPTIONS (SOCKET "$SOCKET",DATABASE 'test',USER 'spider',PASSWORD 'pwd'); |
CREATE TABLE t1 (c INT KEY,c1 BLOB,c2 TEXT) ENGINE=MyISAM; |
CREATE TABLE t2 (c INT KEY,c1 BLOB,c2 TEXT) ENGINE=Spider COMMENT='WRAPPER "mysql",SRV "srv",TABLE "t1"'; |
CREATE TABLE t3 (c INT KEY,c1 BLOB,c2 TEXT) ENGINE=Spider COMMENT='WRAPPER "mysql",SRV "srv",TABLE "t1"'; |
CREATE TABLE t4 SELECT * FROM t2 UNION ALL SELECT * FROM t3; |
Leads to:

|
# Note: It is strongly recommended to uninstall all old Clang & LLVM packages (ref dpkg --list | grep -iE 'clang|llvm' and use apt purge and dpkg --purge to remove the packages), before installing Clang/LLVM 18
|
sudo apt install clang llvm-18 llvm-18-linker-tools llvm-18-runtime llvm-18-tools llvm-18-dev libstdc++-14-dev llvm-dev lld-18
