为execute 语句增加 prepare sql和参数值。
**Case1 : execute ... using ...**
execute 参数来自用户变量。
**输出格式： execute.... // prepare stmt1 from .... ; set var1 = val1 ; set var2 = val2 ;**
样例
```
> CREATE TABLE numbers(pk INTEGER PRIMARY KEY, ui BIGINT UNSIGNED, si BIGINT);
> INSERT INTO numbers VALUES (0, 0, -9223372036854775808), (1, 18446744073709551615, 9223372036854775807);
> SET @si_min = -9223372036854775808;
> SET @si_max = 9223372036854775807;
> PREPARE s2 FROM 'SELECT * FROM numbers WHERE si=?';
Query OK, 0 rows affected (0.00 sec)
> EXECUTE s2 USING @si_min;
+------+------+----------------------+
| pk | ui | si |
+------+------+----------------------+
| 0 | 0 | -9223372036854775808 |
+------+------+----------------------+
1 row in set (0.01 sec)
> EXECUTE s2 USING @si_max;
+------+----------------------+---------------------+
| pk | ui | si |
+------+----------------------+---------------------+
| 1 | 18446744073709551615 | 9223372036854775807 |
+------+----------------------+---------------------+
1 row in set (0.01 sec)
statement_info中的结果:
mysql> select statement from system.statement_info where statement like '%EXECUTE%' \G
*************************** 1. row ***************************
statement: /* 1 queries */
EXECUTE s2 USING @si_min // SELECT * FROM numbers WHERE si=? ; SET @si_min = -9223372036854775808
*************************** 2. row ***************************
statement: /* 1 queries */
EXECUTE s2 USING @si_max // SELECT * FROM numbers WHERE si=? ; SET @si_max = 9223372036854775807
```
**Case2: COM_STMT_EXECUTE**
这类 execute的参数是通过二进制传输的。
**输出格式 execute.... // prepare stmt1 from .... ; param0 ; param1 ...**
样例
```
statement_info中的结果:
execute __mo_stmt_id_1 // prepare __mo_stmt_id_1 from insert into mo_task.sys_cron_task (
