Sending an array of values to Oracle procedure to use in WHERE IN clause

Question

I have a stored procedure in Oracle as shown below:

CREATE PROCEDURE MY_TEST_PROC(
  CUR OUT SYS_REFCURSOR,
  PARAM_THAT_WILL_BE _USED_INSIDE_WHERE_IN
)
AS
B         


        

Answer 1

One way could be to use a VARRAY for the PARAM_THAT_WILL_BE _USED_INSIDE_WHERE_IN parameter and use it as described here
I'm not sure, though, how to call it from c#.

Another way is to use varchar2 with a csv as you stated in your question but without dynamic sql, like this:

CREATE PROCEDURE MY_TEST_PROC(
  CUR OUT SYS_REFCURSOR,
  PARAM_THAT_WILL_BE varchar2)
AS
BEGIN
  OPEN CUR FOR 
    SELECT * 
      FROM MY_TABLE 
     WHERE COL1 IN (
        select regexp_substr(PARAM_THAT_WILL_BE, '[^,]+',1,level) p
          from dual t
       connect by level <= regexp_count(PARAM_THAT_WILL_BE, ',') + 1
)
END;

Answer 2

You can add this comma separated input parameter as a varchar() and use following where statement:

where (','||PARAM_THAT_WILL_BE||',' like '%,'||COL1||',%')

for example if PARAM_THAT_WILL_BE='2,3,4,5' and col1=3 we get:

where (',2,3,4,5,' like '%,3,%') 

and it's TRUE if COL1 value is in this list. Here you don't use a dynamic query so you avoid concerns 1) and 2).

Answer 3

For this scenario i used like this

CREATE PROCEDURE MY_TEST_PROC(CUR OUT SYS_REFCURSOR,A in VARCHAR2 ) AS BEGIN OPEN CUR FOR SELECT * FROM MY_TABLE WHERE COL1 IN (SELECT REGEXP_SUBSTR(**A**,'[^,]+', 1, LEVEL) FROM DUAL CONNECT BY REGEXP_SUBSTR(**A**, '[^,]+', 1, LEVEL) IS NOT NULL) END;

The A value should contain open and closed qutoes('). EX: '512,456,4564' if it one value '512' like this
