===== SETUP =====
## Connection Default
## Disable events from the default connection

## Create user1, user2, user3
CREATE USER user1@localhost;
CREATE USER user2@localhost;
CREATE USER user3@localhost;
GRANT ALL ON *.* to 'user1'@localhost;
GRANT ALL ON *.* to 'user2'@localhost;
GRANT ALL ON *.* to 'user3'@localhost;

## Setup test connection 1
## Setup test connection 2
## Setup test connection 3

## Default connection

## Create data tables
CREATE TABLE test.t1(a INT, b INT, c INT, d INT DEFAULT 0, PRIMARY KEY(a), INDEX index_b(b), INDEX index_cb(c, b));
CREATE TABLE test.t2 LIKE test.t1;
CREATE TABLE test.t3 LIKE test.t1;

## Generate event data from 3 connections
## Connection 1
## Connection 2
## Connection 3
## Connection 2
## Create prepared statements on connection 2
PREPARE st1 FROM 'SELECT SQRT(POW(?,2) + POW(?,2)) AS hypotenuse';
PREPARE st3 FROM 'INSERT INTO test.t1 SELECT * FROM test.t1 WHERE a<=?';
PREPARE st4 FROM '(SELECT a FROM test.t1) UNION (SELECT a+10 FROM test.t1) ORDER BY RAND()*0+a';
## Create stored procedure connection 2
CREATE PROCEDURE SampleProc1()
BEGIN
SET @table = 'test.t1';
SET @s = CONCAT('SELECT * FROM ', @table);
PREPARE st2 FROM @s;
END|

Call SampleProc1() to prepare a statement
CALL SampleProc1();
## Connection default

## Use Connection 2 for default target thread id

## Create index_test() procedure
