How to check if the object is valid or not?

I have a scenario in my stored procedure, where the functions seeks a User_Object and if found (= 1), then it executes.
ex:
IF TEXISTS ('LAB_IN') = 1 THEN
FOR x IN (SELECT COLUMN_NAME, SRC_COL, SRC_TBL, COLUMN_PREFX, COLUMN_STRING_OPP, DEST_TABLE L_UTIL_SRC WHERE SRC_TBL = 'L')
LOOP
VCAT: = CASE WHEN ISCAT > 0 THEN ELSE REPLACE(x.DEST_TABLE, 'UTIL_', '') "END;
vblJOB: = ";
vblJOB: = vblJOB | "CREATE OR REPLACE PROCEDURE SP_ | x.DEST_TABLE |' AS ';
vblJOB: = vblJOB | "PRAGMA AUTONOMOUS_TRANSACTION; ';
vblJOB: = vblJOB | ' vblQueryName VARCHAR2 (150); ';
..........
..........
..........

My question is, what happens if the object (LAB_IN) is not valid. Or if changes have been made to it. How can I do this function NOT run, if the object is not valid... and displays the error message without going any further...

Any suggestions or comments, would apprecaite it...

Thank you!

Hi Frank,.

I made changes to the code. Can you please let me know if that would work. Look's like I am getting a syntax error;

The error messages contain information designed to help solve problems. Always display the full error messages, including the line numbers and the complete code that caused them.

CREATE OR REPLACE PROCEDURE 'PROCEDURE_NAME' (ACE)
VARIABLE1 VARCHAR;
VARIABLE2 VARCHAR;
VARIABLE3 VARCHAR;
VARIABLE4 INT;
BEGIN
IF TEXISTS ('LAB_IN') = 1 THEN

What is TEXISTS? Is - this function that queries user_objects? Perhaps you need to change to get the status.

SELECT MIN (STATUS)
IN OBJ_STATUS
WHERE OWNER = "
AND OBJECT_NAME = 'LAB_IN. '
AND OBJECT_TYPE = 'VIEW.

You need one; After the above statement

IF OBJ_STATUS = "VALID".
THEN
FOR x IN (SELECT COLUMN_NAME, SRC_COL, SRC_TBL, COLUMN_PREFX, COLUMN_STRING_OPP, DEST_TABLE TABLE_NAME WHERE SRC_TBL = 'L')
LOOP
VCAT: = CASE WHEN ISCAT > 0 THEN ELSE REPLACE(x.DEST_TABLE, 'UTIL_', '') "END;
vblJOB: = ";
vblJOB: = vblJOB | "CREATE OR REPLACE PROCEDURE SP_ | x.DEST_TABLE |' AS ';
vblJOB: = vblJOB | "PRAGMA AUTONOMOUS_TRANSACTION; ';
vblJOB: = vblJOB | ' vblQueryName VARCHAR2 (150); ';
..........
..........
..........
EXECUTE IMMEDIATE (vblJOB);
COMMIT;
END LOOP;
ON THE OTHER
DBMS_OUTPUT. Put_line (' table LAB_IN is missing.) Please check...');
END IF;
END IF;
     
IF TEXISTS ('RX_IN') = 1 THEN
SELECT MIN (STATUS)
IN OBJ_STATUS
WHERE OWNER = "
AND OBJECT_NAME = 'RX_IN. '
AND OBJECT_TYPE = 'VIEW.

You need one; After the above statement, too.

IF OBJ_STATUS = "VALID".


THEN
FOR x IN (SELECT COLUMN_NAME, SRC_COL, SRC_TBL, COLUMN_PREFX, COLUMN_STRING_OPP, DEST_TABLE L_UTIL_SRC WHERE SRC_TBL = 'L')
LOOP
VCAT: = CASE WHEN ISCAT > 0 THEN ELSE REPLACE(x.DEST_TABLE, 'UTIL_', '') "END;
vblJOB: = ";
vblJOB: = vblJOB | "CREATE OR REPLACE PROCEDURE SP_ | x.DEST_TABLE |' AS ';
vblJOB: = vblJOB | "PRAGMA AUTONOMOUS_TRANSACTION; ';
vblJOB: = vblJOB | ' vblQueryName VARCHAR2 (150); ';
..........
..........
..........
EXECUTE IMMEDIATE (vblJOB);
COMMIT;
END LOOP;
ON THE OTHER
DBMS_OUTPUT. Put_line (' table RX_IN is missing.) Please check...');
END IF;
END IF;
     
IF TEXISTS ('SUPPL_RX_IN') = 1 THEN
SELECT MIN (STATUS)
IN OBJ_STATUS
WHERE OWNER = "
AND OBJECT_NAME = 'SUPPL_RX_IN. '
AND OBJECT_TYPE = 'VIEW.

The same problem.
Don't make the same mistake 3 times. Don't do so many changes at once to your procedure. Decide when you need to make the same change to 3 different places, do it in only 1 place and make sure it works before making the same change elsewhere.

IF OBJ_STATUS = "VALID".
THEN
FOR x IN (SELECT COLUMN_NAME, SRC_COL, SRC_TBL, COLUMN_PREFX, COLUMN_STRING_OPP, DEST_TABLE L_UTIL_SRC WHERE SRC_TBL = 'L')
LOOP
VCAT: = CASE WHEN ISCAT > 0 THEN ELSE REPLACE(x.DEST_TABLE, 'UTIL_', '') "END;
vblJOB: = ";


vblJOB: = vblJOB | "CREATE OR REPLACE PROCEDURE SP_ | x.DEST_TABLE |' AS ';
vblJOB: = vblJOB | "PRAGMA AUTONOMOUS_TRANSACTION; ';
vblJOB: = vblJOB | ' vblQueryName VARCHAR2 (150); ';
..........
..........
..........
EXECUTE IMMEDIATE (vblJOB);
COMMIT;
END LOOP;
ON THE OTHER

  • What ever the data that we are loading in HFM, how to check if the data are correct or not?

    Hello!

    This is SANDEEP, I loaded data using FDM in HFM. How to check if the data is correct or not, what ever the data I was responsible in HFM.

    Please tell me how to recover the data and what format, clearly can you me the data verification process step by step.

    It would be useful for me...

    Thanks in advance...

    Kind regards

    SANDEEP

    Hi Sandeep,

    I think the best way is to extract data from HFM for the same POV that you have loaded FDM and check if it is the same.

    If you then use HFM 11.1.2.x version

    1. login to the application and go to the menu Administration / extract / data.

    2. set the POV that you have loaded the data, then unzip it. You can open the file unzipped in a notebook

    3. you can compare the file with the data file generated by FDMEE under Outbox folder.

    But what would you give all the data corresponding to the POV that you set. So please ensure that you have the correct POV, defined according to the export FDMEE.

    Thank you

  • HP50g: HP50g - hot to check if the object of the stack is a number?

    How to check if an object on the stack is a number or another type of data? There seems to be no any function to check on 50g.

    50 g advanced users to see, page 1-13:

    "The order TYPE ([left SHIFT] PRG-> TEST-> NXT-> TYPE) accepts any object as argument and returns the number that identifies the type of this object." For example, 'HELLO' TYPE returns 2, the value of a string object. See table of object types in Chapter 3, in the command TYPE, to find objects of calculator and corresponding type numbers.

    Generally want to DUP the object to the level of the stack 1 first of all, because likely you want to do something with it, after checking his type.  The following RPL program checks the type of the object in level 1 of the pile and adds a string to the stack indicating its type.  Only some of the possible types are checked and a generic "something else" translates to others:

    «
    
  TYPE OF DUP
    
  CASE
    
    DUP 0 == THEN DROP 'real number' END
    
    DUP 1 == THEN DROP "complex number" END
    
    DUP 2 == THEN DROP 'chain' END
    
    DUP 3 == THEN DROP "real array" END
    
    DUP 5 is THEN DROP 'list' END
    
    DROP "something else"
    
  END

    Hello

    How knowledge/check if the RMAN backup was performed using a current control file or database catalog? I mean RMAN prompt or sqlplus is it possible to know.

    Thank you

    You're welcome my friend

    You can see them using two methods.

    as I mentioned above, you can see them connect to the catalog database and you can query using the view that I sent

    http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV89601

    the other method is the list command, you must use the list command after connecting using rman "rman target / catalog cat_user/cat_pass@catdbtns" command

    http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV8136

    Check the value of the control_file_record_keep_time parameter. The default value is 7 days. in the output of the list command, if you can see the old backups to the value, you must be sure that the backup information comes from the catalogue database

    SELECT * FROM parameter $ v where name = 'control_file_record_keep_time '.

    an example of command list
