I'm trying to save a CLOB into a variable to perform operations like extract and such. I have this code:
DECLARE
clob_rec CLOB;
n_rec NUMBER:=100;
BEGIN
SELECT LOB INTO clob_rec FROM table1 WHERE ID = 1234;
n_rec := clob_rec.EXTRACT('//XPTO/text()', 'xmlns:XPTO').getNumVal();
END;
I want to save multiple values from the XML to various variables like n_rec. How can get an "instance of the object (CLOB)" to perform functions or methods like extract()?
You need to convert it to an XMLtype first:
DECLARE
clob_rec CLOB;
n_rec NUMBER:=100;
x XMLType;
BEGIN
SELECT LOB INTO clob_rec FROM table1 WHERE ID = 1234;
x := XMLType(clob_rec);
n_rec := x.EXTRACT('//XPTO/text()', 'xmlns:XPTO').getNumVal();
END;

I just want to show USU_USERS table between a declare procedure but it's shows this error when I try to compile
DECLARE
ID_UNICO VARCHAR(200) := 'H3LP';
BEGIN
DECLARE
VID VARCHAR2(200);
VID_USER VARCHAR2(200);
BEGIN
VID := ID_UNICO;
VID_USER := 'SOPORTE';
USR_SP_USERS.CREATE(
VID => VID,
VID_USER => VID_USER,
);
END;
SELECT * from USU_USERS;
END;
NOTE : THIS TABLE HAS MORE THAN ONE ROWS.
PL/SQL is a server-side language only, and as such there's no way to "show" the results of a SELECT statement anywhere. Your SELECT statement needs to put the values it retrieves from the database into a variable or variables. Let's try to give you something which will work:
DECLARE
strID_UNICO VARCHAR(200) := 'H3LP';
strVID VARCHAR2(200);
strVID_USER VARCHAR2(200);
rowUSU_USERS USU_USERS%ROWTYPE;
BEGIN
strVID := strID_UNICO;
strVID_USER := 'SOPORTE';
USR_SP_USERS.CREATE(VID => strVID,
VID_USER => strVID_USER);
SELECT *
INTO rowUSU_USERS
FROM USU_USERS;
END;
Note that if the table USU_USERS has more than one row in it this code will fail. Assuming, though, that USU_USERS has only a single row in it, you could then use DBMS_OUTPUT.PUT_LINE to output the various fields in rowUSU_USERS.
I am using this code to see if it will work for a procedure. I want to be able to make a procedure in which i can decide what data to extract by typing the time ('jan-2020') in which it is recorded and also to decide in which table i want to place the data in (january_2020). i get the error that the table is not able to be used in this context. What do i have to change in the code to be in the right context?
Is it because i am using dynamic sql in a loop that requires the loop to be executed to put the data in the table? or is it because i am using %rowtype as the attribute for the table ALL_DATA to create its own columns? If it is any of these what should i do to change it?
DECLARE
time_v varchar2(9);
table_v varchar2(200);
sql_code varchar2(300);
TYPE Copied_Table IS TABLE OF Gastos%ROWTYPE;
All_Data Copied_Table;
BEGIN
time_v := 'jan-2020';
SELECT *
BULK COLLECT INTO All_Data FROM Gastos
Where TO_CHAR(DATE_, 'MON-YYYY') = UPPER(time_v);
FOR I in All_Data.First .. All_Data.Last LOOP
sql_code := 'INSERT INTO :table_v ( DATE_, DESCRIPTION, ORIGINAL_DESCRIPTION, AMOUNT,
TRANSACTION_TYPE, CATEGORY, ACCOUNT_NAME)
Values ( ALL_Data(i).date_, ALL_Data(i).description, ALL_Data(i).original_description,
ALL_Data(i).amount, ALL_Data(i).transaction_type, ALL_Data(i).category, ALL_Data(i).account_name)';
table_v := january_2020;
execute immediate sql_code
using table_v;
END LOOP;
END upload_monthly_expenses;
Pass table name as input parameter and replace bind variable with normal variable for the table name and concatenate it to the DML statement.Modify your code as below,
CREATE OR REPLACE PROCEDURE upload_monthly_expenses(table_v IN VARCHAR2,time_v IN VARCHAR2) AS
DECLARE
sql_code varchar2(300);
TYPE Copied_Table IS TABLE OF Gastos%ROWTYPE;
All_Data Copied_Table;
BEGIN
SELECT *
BULK COLLECT INTO All_Data FROM Gastos
Where TO_CHAR(DATE_, 'MON-YYYY') = UPPER(time_v);
FOR I in All_Data.First .. All_Data.Last LOOP
sql_code := 'INSERT INTO '||table_v||' ( DATE_, DESCRIPTION, ORIGINAL_DESCRIPTION, AMOUNT,
TRANSACTION_TYPE, CATEGORY, ACCOUNT_NAME)
Values ( ALL_Data(i).date_, ALL_Data(i).description, ALL_Data(i).original_description,
ALL_Data(i).amount, ALL_Data(i).transaction_type, ALL_Data(i).category, ALL_Data(i).account_name)';
execute immediate sql_code;
END LOOP;
END;
From a PL/SQL block procedure can be executed as below,
BEGIN
upload_monthly_expenses('jan-2020','january_2020');
END;
I am trying to reach columns by loop index of a cursor record. Currently i am using multiple variables for each columns thus I think that I should refactor my codes. In java, I'd use reflection to do that but I stuck in PLSQL. Code will explain better
input is passed into from loop.
i_member_awd_rowtype in member_awd%rowtype
.
.
.
--many more inputs
l_step1_company := i_member_awd_rowtype.flt_company;
l_step1_subclass := i_member_awd_rowtype.class_code;
l_step2_company := i_member_awd_rowtype.ret_flt_company;
l_step2_subclass := i_member_awd_rowtype.ret_class_code;
l_step3_company := i_member_awd_rowtype.step3_company;
l_step3_subclass := i_member_awd_rowtype.step3_class_code;
l_step4_company := i_member_awd_rowtype.step4_company;
l_step4_subclass := i_member_awd_rowtype.step4_class_code;
l_step5_company := i_member_awd_rowtype.step5_company;
l_step5_subclass := i_member_awd_rowtype.step5_class_code;
l_step6_company := i_member_awd_rowtype.step6_company;
l_step6_subclass := i_member_awd_rowtype.step6_class_code;
l_step7_company := i_member_awd_rowtype.step7_company;
l_step7_subclass := i_member_awd_rowtype.step7_class_code;
l_step8_company := i_member_awd_rowtype.step8_company;
l_step8_subclass := i_member_awd_rowtype.step8_class_code;
I need to assign single class, company and subclass variables in a loop such as
/*for i in 1 .. 8 loop
l_step_subclass :=
end loop;*/
Is there any way to write as I wanted in PLSQL? Thanks.
The following code block containing a Dynamic SQL statement might be used, assuming you wanna gather the records for each identity column(id) of the table :
SQL> set serveroutput on
SQL> declare
v_tbl varchar2(31) := 'member_awd';
v_sql varchar2(250);
v_id member_awd.id%type := :p_id;
type typ is table of varchar2(32767) index by binary_integer;
l_step_subclass typ;
begin
for c in ( select column_id, column_name
from user_tab_columns
where table_name = upper(v_tbl) order by column_id )
loop
v_sql := 'select '||c.column_name||' from '||v_tbl||' where id = :i_id ';
execute immediate v_sql into l_step_subclass(c.column_id) using v_id;
dbms_output.put_line(l_step_subclass(c.column_id));
end loop;
end;
/
where the variable l_step_subclass is converted to the array type. This way, all values for each individual column are assigned to this column local variable.
I have problem with my plsql code. It's just part of my whole job.
declare
id number(2):=1; (here is function which returns any value)
check VARCHAR2(100);
begin
select COUNT(*) into check from T_SDSN_LOG Where ANY_ID=id AND CHECK LIKE
'NAME';
dbms_output.put_line(check);
end;
In this case, my select returns 0 althought it should be 2.
If I change the part
Where ANY_ID=id to
Where ANY_ID=2 it works perfectly. Any advices? I need id to be variable as a return value from function.
This uses a locally defined function so it isn't available in the SQL but can be referenced in the PL/SQL.
DECLARE
lnum_id NUMBER := return_id;
lnum_check VARCHAR2(100);
FUNCTION return_id
RETURN NUMBER
IS
BEGIN
RETURN 123456;
END;
BEGIN
lnum_id := return_id;
SELECT COUNT(*)
INTO lnum_check
FROM my_table
WHERE table_id = lnum_id;
DBMS_OUTPUT.put_line(lnum_check);
END;
You will presumably want this functionality in a package in which case you can declare the function in the package header, write the code for the function in the body and then reference it in the SQL itself. So if I declare a function (FNC_RETURN_ID) in a package called PKG_DATA_CHECKS that returns a NUMBER I can do the following;
DECLARE
lnum_id NUMBER;
lnum_check VARCHAR2(100);
BEGIN
SELECT COUNT(*)
INTO lnum_check
FROM my_table
WHERE table_id = (SELECT pkg_data_checks.fnc_return_id FROM dual);
DBMS_OUTPUT.put_line(lnum_check);
END;
How do I insert variable values in to a table record in an oracle procedure?
if pCount1=0 then
insert into opions(qid,otext,oflag)
(rec.pQid, rec.pOptions, rec.pCorrect);
end if;
where rec.* are the variables of the procedure
Are you looking for one of these statements (which are functionally equivalent)?
insert into opions(qid,otext,oflag)
values (rec.pQid, rec.pOptions, rec.pCorrect);
insert into opions(qid,otext,oflag)
select rec.pQid, rec.pOptions, rec.pCorrect from dual;
This assumes that rec is defined somewhere else in the stored procedure. Otherwise, you need to use the second form with rec defined in the from clause.
Try:
CREATE OR REPLACE PROCEDURE SOME_PROC AS
nQid NUMBER;
strOptions VARCHAR2(100);
strCorrect VARCHAR2(1);
BEGIN
nQid := 1;
strOptions := 1234;
strCorrect := 'Y';
INSERT INTO OPIONS(qid, otext, oflag)
VALUES (nQid, strOptions, strCorrect);
END SOME_PROC;
Best of luck.
