An application uses one user as a container of objects(this user is stripped of ALL privileges), and other users that can access objects in this unique schema depending on their privileges.
There can be multiple installations of the application in one database, therefore many such schemes. An environment variable APP_UNIQUE_SCHEMA points to a current unique schema.
So instead of typing
select * from my_unique_schema.my_table I want to set a current schema for sqlplus session in glogin.sql.
It would have been nice if I could have entered in glogon.sql the following line
alter session set current_schema=$APP_UNIQUE_SCHEMA;
BUT it does not work. sqlplus does not resolve the reference to an environment variable. I cannot figure out how to get the value of an environment variable in sqlplus.
1) A reverse engineering tool that I can point to an Oracle schema and get a "baseline" script to re-create that schema from scratch, with decently formatted DDL files (1 per object) neatly organized in a directory tree (by object type) and called in the correct order. Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to populate (insert) those tables as part of the script.
2) a diff tool that I can point to a pair of Oracle instances (source and target) containing a given schema and get a "delta" script to alter the target schema so that it becomes identical to the source schema. If data loss occurs on the target instance (i.e. drop a column) I would like to find a warning comment inserted in the script (e.g. "-- Attention: data migration DML needed here?"). Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to update (delete, update and insert) the data in the target tables to become identical to the contents in the source tables *without* deleting and re-inserting all rows (or dropping, recreating and repopulating the table).
3) I would like the above two tools (that, as you will have recognized, are basic to putting your database design under version control) to be open-source, with a command-line interface and a vibrant community backing them.
The problem is that this connection errors when I try to connect using my SQuirreL client. My developers want to connecting using the SID or the SERVICE_NAME and by using the "New Method" syntax, not the "Old Method" syntax. According to the documentation the "New Method" syntax works with the SERVICE_NAME or the SID. The "Old Method" only works with the SID.
# Host name is vmwwin7634.na.SAS.com # SID is sting2 # SERVICE_NAME is sting2.na.sas.com
PROBLEM using SID errors ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2 THIS WORKS using SERVICE_NAME ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2.na.sas.com
I am using SQuirreL Client version 3.4.0
# Here is the tnsnames.ora entry on the server. STING2 = (DESCRIPTION =
[code]...
# In this documentation it says, "On new syntax SERVICE may be a oracle service name or a SID."You can find this on the orafax wiki under JDBC#Thin_driver.
# I was able to connect with the "old method" using the SID only, SERVICE_NAME errors jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521:sting2.na.sas.com (SQuirreL client error, "Unexpected Error occurred attempting to open an SQL connection.") jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521:sting2 (this works)
# "New Method" jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2.na.sas.com (this works) jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2 (this errors) (SQuirreL client error, "Unexpected Error occurred attempting to open an SQL connection.")
I have new virtual UNIX machine and I installed oracle client on /usr/lib/oracle. Also I have a oracle database and I am able to connect to this database from my desktop sql developer.
So now I am trying to connect from new UNIX machine. Where I created tnsnames.ora file under /usr/lib/oracle/network/admin and before connecting did export the following
ORA-12545: Connect failed because target host or object does not exist. Not sure what I missed here. using same tns file I am able to connect from sql developer on windows.
I need to install Oracle client to get latest sql plus working on client pc as the problem is, i am not able to find out where i can download this , i just need the sql plus as i am not able use many commands because when i installed oracle forms 6i client tool , sql plus 8.0 got installed.
I want to use BR*Tools to administer an Oracle database. I have installed BrGUI local, set the JAVA Home variable and edited the brgui.properties file accordingly.I am able to login, but the menues are mising. The login screen is incomplete.
I usually work in oracle using the different editors like toad, plsql developer etc. I felt command line is good utility because of various supporting points. I am not sure what kind of command line tools is available/used. I am using pretty straight command line (run->cmd, then enter username and password).
The best command line tools available. What is generally used command line tools.
The version is Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi. for Unix AIX 5
I install the ODBC Driver Manager, Basic Instant Client, ODBC Instant Client packages (libsqora.so, odbc_update_ini.sh).
The error:

I have an Oracle server on CentOS 5.4, I can visit isqlplus on server, but I can't visit isqlplus on a windows client. ping works between server and client. I remember client doesn't need to install software via isqlplus, but I am not pretty sure.
Which of the below is considered a bind variable. In example one proc. Test the parameter p1 is directly used in the query, so this can be considered as a bind variable.
Is that true about the second proc. where p1 is assigned to a local variable v1 , or this needs hard parsing because v1 is not a bind variable ?
Create or replace procedure test(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS BEGIN OPEN p_refcursor FOR select * from Test_tab WHERE item=p1; END; ------------ Create or replace procedure test1(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS v1 varchar2(100):=p1; BEGIN OPEN p_refcursor FOR select * from Test_tab WHERE item=v1; END;
Here is a simple sqlplus line command with & substitution run time variable.
set verify off; SQL> SELECT * FROM emp where sal >&SAL; Enter value for sal:
Now as you see, oracle asks to Enter Value for substitution variable in line just below the SQL>. I wonder if there is one or more line could be left there so to improve the readability. So it should look like:
set verify off; SQL> SELECT * FROM emp where sal >&SAL;
Declare a variable called sal to store the salary of an employee. In the executable part of the program, do the following:
a.Store an employee name in a substitution variable. b.Store his or her salary in a variable. c.If the salary is less than 5,000, give the employee a 10% raise and display the message "<Employee Name> salary updated" in the window. d.If the salary is more Last Name Message than or equal to 3,000, print the employee's salary in the format, "<Employee Name> earns ............. No raise is given."
So the result should ask for the last name
- Himuro and message should show [Himuro's salary updated] - Greenberg [Greenberg earns 12000. No raise is given.] - Patel [Patel's salary updated]
Here is my PL/SQL
set serveroutput on
DECLARE v_emp_sal employees.salary%type; v_emp_last_name employees.last_name%type; BEGIN v_emp_last_name :=initcap('&emplastname'); SELECT salary INTO v_emp_sal [code]......
question: How can I get the apostrophe in the dbms_output.put_line. Attached is the create employees table code.
I'm not able to run SQL *Plus on my machine. It is giving me below error.
Error 6 initializing SQL*Plus Message file sp1<lang>.msb not found SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
Setting of PATH environment variable is as below. If I remove below highlighted part I'm able to run SQL * Plus. I cannot remove this because it is required to run my application.
