SQL & PL/SQL :: Column Renaming From Query Output?
Jul 14, 2010
I want to be able to name a column created from my query.
Query is:
select A.OrigRef, A.DisplayName, A.ExtCode, count(CalcId)
from OrigRefView A, CalcView B where A.OrigRef = B.NewRef and A.OrigRef like 'AB%'
group by A.OrigRef, A.DisplayName, A.ExtCode
order by A.SusRef
and it returns the Count in "column4" Is there a way I can get the query to output a different column name without creating a whole new table (i.e. not by creating a new table for my query output and then running a new procedure at the end to rename the column...)?
i have a problem in renaming the column of a table and it throws a strange error-"ORA-14155: missing PARTITION or SUBPARTITION keyword " ,but i have used correct syntax which is that " alter table temp rename id to num; " where is the problem.
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production PL/SQL Release 11.1.0.6.0 - Production "CORE 11.1.0.6.0 Production"
Is there any way to rename a column in a table A, so that it is changed wherever it is used, like all the procedures that uses this column, or other tables that has reference to this table A?
I need to have columns dynamically defined in my SQL based on the column values in the table.
Selct emp_no,dept_no,grade from emp; emp_no dept_no grade ---------------------------------- 1 10 A 2 20 B 3 20 A 4 10 C 5 10 A 6 20 C 7 10 B 8 20 C
I need the output as dept_no Count_A Count_B Count_C --------------------------------------------- 10 2 1 1 20 1 1 2
I can write hard coded sql to get this output but I need the count columns to be generated dynamically as there could be new entries in the grade column later. For example if there is a entry as D for the grade column my SQL should have a column count_D.
i have created a table called table2,with only one column as text,
SQL> select regexp_replace(text,'[:]',chr(10)) text from table2;
TEXT -------------------------------------------------------------------------------- 1 amar 11-jan-2011 15000
2 manju 22-feb-2011 20000 and i have to get output like this, TEXT -------------------------------------------------------------------------------- ID 1 NAME amar DATEOFJOINING 11-jan-2011 SALARY 150000
I am trying to get query output into textfile.The following procedure is working fine by creating directory as follows in sys user.The output is getting onto text file and it seen on server machine even.My question is I want to see the text file on local machine also instead of everytime connecting to server machine drive.How can I perform that?
create or replace directory INFO_DIR as 'D:Swapna'; grant read, write on directory INFO_DIR to fairpoint; CREATE OR REPLACE PROCEDURE FAIRPOINT.utl_file_test_write_xls(filename in VARCHAR2 ) IS output_fileutl_file.file_type; v_pathVARCHAR2(500); v_stringVARCHAR2(4000); v_sqlstrVARCHAR2(2000); BEGIN BEGIN [code]....
<h4><font color="Blue"> CREATE OR REPLACE PROCEDURE SP_SSN_BY_PIN( V_REQUESTEDPIN IN VARCHAR2, V_SSN OUT CHAR) AS BEGIN SELECT
[code]....
As you can see the type of the SSN column is NUMBER(13,0). But I leftpad it with 0 and assign it to my output paramter V_SSN, whose type is CHAR. But I get 111196100099 instead of 0111196100099. I've tried TO_CHAR(LPAD(SSN,13,'0')) but still doesn't work. However, if I return the left padded SSN inside a SYS_REFCURSOR I get what I want.
below query is returning two rows.The thing now happening is the query is returning the output for both the case statements.But what is need only when the first case staement is NULL then it should go for second case.
SELECT DISTINCT CASE WHEN esc.x1 = Substr(inp.y, 0, 3) AND esc.x2 = Substr(inp.y, 4, 2)THEN esc.cc WHEN esc.mcc = Substr(inp.y, 0, 3) AND esc.mnc = Substr(inp.y, 4, 3)THEN esc.cc [code]....
I tried using rownum=1 but it filters out valid records.correcting the above query so that if the first case is null then only it should go for second case.
I'm trying to get size of CLOB column but not getting any output.

create a procedure so that I could get minus query of 2 table as a result.
I have two table 1- src_table_list ,2- tgt_table_list both tables have 2 columns : serial_no,table_name and 100 records each. and details mentioned in column "table_name" are actually tables name which present in my testing database.
so I need one procedure which will pick one table_name from src_table_list and one table_name from tgt_table_name each time recursively and provide minus query as a result. as below.
select c1,c2,c3,c4 from table1 --(fetched from src_table_list) minus select b1,b2,b3,b4 from table2 --(fetched from tgt_table_list)
create the procedure..as I have to prepare minus query for more than 200 tables and then I need to test them for integration testing..
When i run the below mentioned query(similar query)on TOAD. It will run without any errors and i can see "PL/SQL Procedure successfully completed" in the task bar.....
However i am unable to see the output for the query.
print the the query output on TOAD ....
**** Sample Query Starts ***** DECLARE i PLS_INTEGER; BEGIN SELECT NVL(i, 93) INTO i FROM DUAL; --print i; --dbms_output.put_line('i1: ' || i); END; **** Sample Query Ends*****
**** Actual Query Starts ***** ----------------------------------------------------------------- DECLARE UnxDate number(6); MyResult number(6); Todaysdate date := TO_DATE('17-01-2012 00:00:00','dd-mm-yyyy hh24:mi:ss'); BEGIN SELECT ROUND (Todaysdate - TO_DATE('01-jan-1970','dd-mon-yyyy') ) INTO UnxDate FROM dual; [code]......
There are several stages for sql processing in 10g2 database concept document.The following stages are necessary for each type of statement processing:
■ Stage 1: Create a Cursor ■ Stage 2: Parse the Statement ■ Stage 5: Bind Any Variables ■ Stage 7: Run the Statement ■ Stage 9: Close the Cursor Optionally, you can include another stage: ■ Stage 6: Parallelize the Statement
Queries (SELECTs) require several additional stages, as shown in Figure 241:
■ Stage 3: Describe Results of a Query ■ Stage 4: Define Output of a Query ■ Stage 8: Fetch Rows of a Query
Stage 3: Describe Results of a Query The describe stage is necessary only if the characteristics of a query's result are not known; for example, when a query is entered interactively by a user. In this case, the describe stage determines the characteristics (datatypes, lengths, and names) of a query's result.
Stage 4: Define Output of a Query In the define stage for queries, you specify the location, size, and datatype of variables defined to receive each fetched value. These variables are called define variables. Oracle performs datatype conversion if necessary.
I still don't understand what's Stage 3: Describe Results of a Query and Stage 4: Define Output of a Query.
I would like to try to rename a newly created dB. Referring to the topic posted on your website[URL]... had some clarification before executing the dbrename.sql mentioned there:
After modifying the the init.ora and tnsnames.ora, do I have to rename all OLD, existing directory path (for controlfiles, datafiles, etc.) with the new-- meaning I don't have to create another directory for it's 'NEW' name?
I have cretaed an external table to read data to a table from a csv file placed in "c:oracleoradataspmap1utl". The csv file name is say "pildata.csv"
I have cretaed a package to read data from the exteranl table and to insert it into a table.
INSERT INTO M_PILEINT SELECT A.AREA AS "AREA", A.SUB_FAC_DESC AS "SUB_FAC_DESC", A.SCOPE_DETAIL AS "SCOPE_DETAIL", A.MTO_ISSUE_DATE AS "MTO_ISSUE_DATE", A.MTO_TAKE_BY AS "MTO_TAKE_BY", A.COMMODITY_CODE AS "SECTION" A.PILE_NAME AS "PILE_NAME" FROM M_EXE_PILE A
(where M_EXE_PILE A is the external table which is reading from pildata.csv)
The package runs good and data is populated to M_PILEINT .Is there a way , I can rename the csv file (say to pildata_logxxxx.csv.. something like that) from within the package.Whenever the package is run , it will copy the data from exteranl table and renames the csv file to something else..?
