You want to use an OBJECT INDENTIFIER

select count(*) into c from identifier(:table_name);
return c;

Using TABLE():
create or replace procedure test(table_name varchar)
returns integer

How can I set a variable in stored procedure and use it in following query to be executed.
create or replace procedure sp1()
returns table (dealer_id varchar, dealershipgroup_name varchar)
language sql
as
$$
declare
create_query varchar;
res resultset;
MISSING_DEALER NUMBER(38,0) default 0;
begin
MISSING_DEALER := 100;
select_query := 'WITH CTE AS(
SELECT dealer_id,
CASE WHEN dealer_id=:MISSING_DEALER then \'Abc\'
WHEN dealershipgroup IS NULL then \'\'
ELSE dealershipgroup end as dealershipgroup FROM TBL )
select * from CTE';
res:= (execute immediate : select_query);
return table(res);
end;
$$;
call sp1();
Could someone please suggest how can I use MISSING_DEALER in the query. I am currently getting the following error
Uncaught exception of type 'STATEMENT_ERROR' on line 28 at position 9 : SQL compilation error: error line 8 at position 26 Bind variable :MISSING_DEALER not set
You need to concatenate the string parts of your SQL statement with the variable. This is covered in the documentation if you look at the end of the section here
create or replace procedure create_src_table()
returns table (name varchar, age number(10,0),dob date)
language sql as
$$
declare
create_query varchar;
res resultset;
begin
create_query := `CREATE TEMPORARY TABLE SRC_TEMP_TBL AS SELECT * FROM
(WITH CTE_1 AS (SELECT * FROM "DB"."DW"."USER_TBL" WHERE name='rahul'),
CTE_2 AS (SELECT * FROM CTE_1 WHERE CAST(DOB AS DATE)<2000-05-01)
SELECT name,age,dob FROM CTE_2 limit 10)`;
res := (execute immediate : create_query);
return table(res);
end;
$$;
call create_src_table();
Could someone please help in how to write multiline sql query. I found few answers that indicate using backtick in javascript but not sure how to achieve it in sql.
Multi-statement SQL should be wrapped inside BEGIN ... END block:
EXECUTE IMMEDIATE 'BEGIN
statement1;
statement2;
...
END;';
Sample:
I want to create stored procedure for select statment below is procedure i have created but it giving data ouput blank
CREATE OR REPLACE PROCEDURE public.deactivate_unpaid_accounts()
LANGUAGE 'sql'
AS $BODY$
select * from employees where salary=10000
$BODY$;
CALL deactivate_unpaid_accounts();
Procedures (which weren't available in 9.5 to begin with) are not intended to return result sets.
If you want to return a result, you should use a function in Postgres.
CREATE OR REPLACE FUNCTION public.deactivate_unpaid_accounts()
returns setof employees
LANGUAGE sql
AS $BODY$
select *
from employees
where salary=10000;
$BODY$;
Then use it like this:
select *
from deactivate_unpaid_accounts();
I need to create a record type to contain the result set of the above query of
V_SQL VARCHAR2(200) := 'SELECT T1.'||record_id||',T1.'||card_no||',T2.TEST_CARD_NO, T1.'||type_cc||' FROM '|| table_name||' T1
INNER JOIN TEST T2 ON
T2.ID = T1.'||record_id;
So that I can use t1 C_BRNGB_EXTRACT%ROWTYPE (plus another column for t2.col4%TYPE inside l_BRNGB_EXTRACT) inside loop execute statement
CREATE OR REPLACE PROCEDURE "GCCPMAINT"."FUNCTION_CURSOR"(table_name VARCHAR2,record_id VARCHAR2,card_no VARCHAR2,type_cc VARCHAR2)
AS
limit_in NUMBER:=100;
V_SQL VARCHAR2(200) := 'SELECT T1.'||record_id||',T1.'||card_no||',T2.TEST_CARD_NO, T1.'||type_cc||' FROM '|| table_name||' T1
INNER JOIN TEST T2 ON
T2.ID = T1.'||record_id;
TYPE BRNGB_EXTRACT IS REF CURSOR;
C_BRNGB_EXTRACT BRNGB_EXTRACT;
TYPE BRNGB_EXTRACT1 IS TABLE OF C_BRNGB_EXTRACT%ROWTYPE;
l_BRNGB_EXTRACT BRNGB_EXTRACT1;
BEGIN
OPEN C_BRNGB_EXTRACT FOR V_SQL;
LOOP
FETCH C_BRNGB_EXTRACT BULK COLLECT INTO l_BRNGB_EXTRACT LIMIT limit_in;
EXIT WHEN l_BRNGB_EXTRACT.COUNT = 0;
FORALL indx IN 1 .. l_BRNGB_EXTRACT.COUNT
EXECUTE IMMEDIATE 'UPDATE table_name SET CARD_NO=:1 WHERE CARD_NO=:2 AND RECORD_ID=:3' USING l_BRNGB_EXTRACT(indx).test_card_no,l_BRNGB_EXTRACT(indx).CARD_NO,l_BRNGB_EXTRACT(indx).RECORD_ID;
END LOOP;
CLOSE C_BRNGB_EXTRACT;
COMMIT;
END;
For a above stored procedure I'm getting the following error
PLS-00320: the declaration of the type of this expression is
incomplete or malformed PL/SQL: Item ignored PLS-00597: expression
'L_BRNGB_EXTRACT' in the INTO list is of wrong type PL/SQL: SQL
Statement ignored PLS-00487: Invalid reference to variable
'C_BRNGB_EXTRACT%ROWTYPE'
Please help me to solve this.
i got the solution
TYPE BRNGB_EXTRACT IS REF CURSOR;
C_BRNGB_EXTRACT BRNGB_EXTRACT;
-- TYPE BRNGB_EXTRACT1 IS TABLE OF C_BRNGB_EXTRACT%ROWTYPE;
TYPE BRNGB_EXTRACT1 IS RECORD (

);
type test_rec_arr is table of BRNGB_EXTRACT1 index by pls_integer;
l_BRNGB_EXTRACT test_rec_arr;
I am preparing stored procedure with oracle .I m using multiple inner joins with the same table where an input parameter value is checked within each inner join. I want to eliminate particular inner join if the input parameter is null
You would need to use dynamic SQL to construct the appropriate query for the parameters like this:
PROCEDURE myproc (p1 VARCHAR2) IS
l_sql LONG;
l_cursor SYS_REFCURSOR;
BEGIN
l_sql := 'SELECT a, b, c FROM table1';
IF p1 IS NOT NULL THEN
l_sql := l_sql || ' JOIN table2 ON table2.x = table1.x';
END IF;
l_sql := l_sql || ' WHERE table1.y = :bind1';
OPEN l_cursor FOR l_sql USING 123;
...
END;
