PowerShell：ODBC DSN连接中的多个查询

Question

我想在ODBC DSN MySql连接中执行多个查询。如果我只执行一个查询它工作正常。但是，如果我尝试执行多次，我总会得到错误：

"ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.0.84-community]You have an error in your SQL syntax; check the 
manual that corresponds to your MySQL server version for the right syntax to use near 'UPDATE TABLE SET ID = '5' WHERE TYPE = '500' AND ID' 
at line 2"

我的剧本：

$qrys = @"
UPDATE TABLE SET ID = '5' WHERE TYPE = '500' AND ID = '0';
UPDATE TABLE SET ID = '6' WHERE TYPE = '600' AND ID = '0';
UPDATE TABLE SET ID = '7' WHERE TYPE = '700' AND ID = '0';
UPDATE TABLE SET ID = '8' WHERE TYPE = '800' AND ID = '0';
"@


$conn = new-object System.Data.Odbc.OdbcConnection
$conn.connectionstring = "DSN=MYDB"
$conn.open()

foreach ($sqlCommand in $qrys) {

    $cmd = New-object System.Data.Odbc.OdbcCommand($sqlCommand,$conn)
    $dataset = New-Object System.Data.DataSet
    (New-Object System.Data.Odbc.OdbcDataAdapter($cmd)).Fill($dataSet) 

}
$conn.Close()

有什么想法吗？提前致谢

默认情况下，MySql不启用多个查询。将public class ShootableBox : MonoBehaviour { Animator anim; public int currentHealth = 3; public int enemyKilled; // Count how many enemies you have killed public float currentHealthLength; bool isSinking; // To trigger the dead enemy to sink public float sinkSpeed = 1f; // Sink speed void Start() { anim = GetComponent<Animator>(); currentHealthLength = Screen.width/2; enemyKilled = 0; } void Update () { // If the enemy should be sinking... if(isSinking) { transform.Translate (-Vector3.up * sinkSpeed * Time.deltaTime); } } public void Damage(int damageAmount) { //subtract damage amount when Damage function is called currentHealth -= damageAmount; //Check if health has fallen below zero if (currentHealth <= 0) { enemyKilled = enemyKilled + 1; //if health has fallen below zero, deactivate it anim.SetTrigger ("isDead"); //transform.GetComponent<NavMeshAgent> ().Stop (); // Find and disable the Nav Mesh Agent. GetComponent <NavMeshAgent> ().enabled = false; // Find the rigidbody component and make it kinematic (since we use Translate to sink the enemy). GetComponent <Rigidbody> ().isKinematic = true; Invoke ("StartSinking", 2.5f); } else { anim.SetTrigger("isHit"); anim.SetTrigger("isRun2"); } } public void StartSinking() { // The enemy should now sink. isSinking = true; // After 2 seconds destory the enemy. Destroy (gameObject, 8f); } // My problem is somewhere on this part public void OnGUI() { GUI.contentColor = Color.yellow; if (enemyKilled != 0) { GUI.Box(new Rect(5, 5, currentHealthLength, 20), "Enemies killed: " + enemyKilled ); } } } 添加到连接字符串，或在DSN配置对话框中启用复选框OPTIONS=67108864：
