我如何使用plsql像'a','b','c'那样转换'a,b,c',因为在我的过程中我需要进行一个使用“ in”的“ where”,但是调用程序时我无法通过'a','b','c'

我的程序在下面

using System.Collections.Generic;
using UnityEngine;

[AddComponentMenu("Camera-Control/Mouse Look")]
public class MouseLook : MonoBehaviour
{

    public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
    public RotationAxes axes = RotationAxes.MouseXAndY;
    public float sensitivityX = 15F;
    public float sensitivityY = 15F;

    public float minimumX = -360F;
    public float maximumX = 360F;

    public float minimumY = -60F;
    public float maximumY = 60F;

    float rotationY = 0F;

    void Update()
    {
        if (Input.touchCount > 0)
        {
            Touch touch = Input.GetTouch(0);
            float turnAngleChange = (touch.deltaPosition.x / Screen.width) * sensitivityX;
            float pitchAngleChange = (touch.deltaPosition.y / Screen.height) * sensitivityY;

            // Handle any pitch rotation
            if (axes == RotationAxes.MouseXAndY || axes == RotationAxes.MouseY)
            {
                rotationY = Mathf.Clamp(rotationY + pitchAngleChange, minimumY, maximumY);
                transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0f);
            }

            // Handle any turn rotation
            if (axes == RotationAxes.MouseXAndY || axes == RotationAxes.MouseX)
            {
                transform.Rotate(0f, turnAngleChange, 0f);
            }
        }

        void Start()
        {
            //if(!networkView.isMine)
            //enabled = false;

            // Make the rigid body not change rotation
            //if (rigidbody)
            //rigidbody.freezeRotation = true;
        }
    }
}

可能您可以使用类似

with data as
  (select 'a,b,c' col 
     from dual)
select regexp_substr(col, '[^,]+', 1, level) result
from data
connect by level <= length(regexp_replace(col, '[^,]+')) + 1; 

上面将产生输出-

RESULT
a
b
c

这就是您可以在IN查询中使用的内容

如果我了解这种情况的正确性,则需要构建一个函数,以在SQL语句的WHERE子句中使用。一种方法是使用流水线表函数,查看您的代码,我想您知道这是什么。

因此,您需要将'a,b,c'转换为包含值'a','b'和'c'的数组。这可以通过WHILE循环,SUBSTR和INSTR来完成。

CREATE FUNCTION convert_for_in(p_string IN VARCHAR2) 
  RETURN <TableType of VARCHAR(1)> PIPELINED IS
BEGIN
  FOR no_chr IN 1 .. (LENGTH (p_string) + 1) / 2 LOOP
    PIPE_ROW (SUBSTR(p_string, 2 * no_chr - 1, 1);
  END LOOP;
END;

并添加到WHERE子句

AND ... IN (SELECT * from table (convert_for_in('a,b,c')))

有帮助吗?

谢谢,我可以解决我的问题 留下来了: 选择regexp_substr(P_CLASE,'[^,] +',1,level)结果                                 从DUAL                                 按级别连接<= length(regexp_replace(P_CLASE,'[^,] +'))+ 1
