I'm trying to do is create 4 simple tables. This is my first project using SQL so I'm totally new to it, not just SQL itself but database design/management, including foreign/primary key concepts. I think that's why the errors are being generated due to a duplication of foreign key names (perhaps?) but I really don't where I'm going wrong with the design structure in terms of the FK's and the relationships.
Added the error report in the attachment.
Create Table Hotel
(Hotel_No Char(4 Byte) Not Null,
H_Name VarChar2(20 Byte) Not Null,
H_Address VarChar2(30 Byte),
Constraint Hotel_PK Primary Key (Hotel_No));
I have a table called test_renames that has two columns(new_name and old_name) and one row with the following values
NEW_NAME OLD_NAME DRUG10 DRUG1
I have another table called SH0 that has 10,000 rows and the column of interest is called ITEM1. ITEM 1 contains the following distinct drug names:
DRUG1,DRUG2,DRUG3,DRUG4,DRUG5
Each DRUG has multiple rows associated with it.
I need to only update rows for DRUG1 and set the name from DRUG1 to DRUG10 for all rows where ITEM1 is DRUG1.
However I need to write this update statement by joining with the values in the test_renames table that contains the NEW_NAME and the OLD_NAME.
DRUG1 has 2,000 rows associated with it. The following SQL statement gives me 2,000 rows
(SELECT NVL(CHG.NEW_NAME, SH.ITEM1) FROM test_renames CHG,sh0 sh WHERE UPPER(SH.ITEM1) = UPPER(CHG.OLD_NAME) AND UPPER(SH.ITEM1) IN (SELECT UPPER(OLD_NAME) from test_renames))
However when I run the following update statement, it appears that the SQL query updates all the 10,000 rows in the table instead of just touching the 2,000 rows for DRUG1. It does change all the rows for DRUG1 to DRUG10, but all the other ITEM1 values become null. What I need from the update statement is only chnage the rows for DRUG1 to DRUG10 and leave the other rows that I associated with DRUG2, DRUG3 etc. Here is my update statement.
UPDATE SH0 SH SET ITEM1 = (SELECT NVL(CHG.NEW_NAME, SH.ITEM1) FROM test_renames CHG WHERE UPPER(SH.ITEM1) = UPPER(CHG.OLD_NAME) AND UPPER(SH.ITEM1) IN (SELECT UPPER(OLD_NAME) from test_renames))
This update statement touches all 10,000 rows. I am looking to update only the relevant 2,000 rows for DRUG1.
I am issuing an update statement in which I am using multiple tables it is giving me an error " set keyword missing"
update E_CONT_DETAIL_NUMB_VALUE ecdnv, y_obj_category yoc, t_contact tc set ecdnv.ContTPRecCount = 1000 where tc.default_category_id = (select primary_key from y_ojb_category where tree_position = 'CONT') and ecdnv.detail_field_id=tc.default_category_id;

We all know Primary key doesnt treat NULL as a value. But the above statement is fine to be executed without problem. Is this something to be highlighted? or am i not right in understanding 'var1 varchar2(20) null '?
I am attempting to read from the maillog of our server, but I wish to make as few changes as possible for fear of blocking other systems access to the file.
I was initially going to call create directory maillogs as '/var/log/maillog' and then drop directory maillogs; when I was done but I found my user does not have "create any directory" permissions.
Rather than compromise security of the existing database configuration, I thought I would permanently add the maillogs to the list of available data directories. Are there any implications to the filesystem if I do this, or should I be able to add this without consideration of affects.
Understand that I will only be opening the file for (R) READ TEXT access only.
Primarily I am concerned that Oracle (in the background) will keep a file pointer open or something of that nature that would block other programs from writing to the file even after I close the file pointer. I want to make as little impact as possible to the file system.
create table SELECTION_BOOKMARK( INSTALLATION_ID SMALLINT NOT NULL, BOOKMARK_ID SMALLINT NOT NULL, NAME VARCHAR2(50) NOT NULL, SORT_ORDER SMALLINT NULL );
When I execute this statement as part of a SQL script, it throws the error "ORA-01003: no statement parsed". If I execute it as a stand alone sql command, it returns no error.
Here's the strange thing, though. Even when it throws the error message the table is created. Later on in the script, I execute the following command:
alter table SELECTION_BOOKMARK add primary key(INSTALLATION_ID,BOOKMARK_ID);
This command also throws the above mentioned error, but once again the command executes - the primary key is created.Well, I don't like having a script that throws errors. Eventually I'll have to give this script to a dba in another organization and I don't want my script to be throwing errors - even if it's apparently working correctly despite the errors.
I've to create a table which has 650 fields and the total length of CREATE TABLE statement got to be more than 4000 characters.I've to create the table by inserting the CREATE TABLE statment in a variable (V1) then by using EXECUTE IMMEDIATE V1 Since VARCHAR2 only supports upto 4000 characters length string, how can I create such table??
DECLARE V1 VARCHAR2(4000); BEGIN V1 := -- CREATE TALBE STATEMENT WITH LENGTH MORE THAN 4000 EXECUTE IMMEDIATE V1; END;

I have created 2 different databases and each have their own schema user for eg we have database ALIVE with user allive and the other database RLIVE with user rllive , actually we have implemented new module in ALIVE database and in the process we created many tables , synonyms , index and other objects now we want to list out all the tables ,sequences as scripts which are not present in RLIVE and create them in RLIVE as new objects.
I need to run 5 scripts to create 5 tables, seems each table needs to take 2 hrs, so I plan to put all 5 commands together
so i would have tables.sql to contain the following
do you know how to add time in beginning and end , so I can figure it out how long does this take to create 5 tables, use spool too?
create table a as select * from ........ ; create table b as select * from ........ ; create table c as select * from ........ ; create table d as select * from ........ ; create table e as select * from ........ ;
We have an application is must be connected to our database for specific requirements in our company but this application has a very bug thing as we must write the super DB password "Like HR password as example" clear in some files and these files must be shared so developers can use the HR password to do any action !!! I know that this application is a problem but we have to install
I can do this by creating trigger on each table will restrict DML. As example: if the operating system user is XXX, the trigger restrict the action. But not logic at all to create more than 1000 triggers on schema (This will impact badly on DB performance).
So, i need to create one trigger to fire before doing any DML on all schema tables. As example: If "MMM" the administrator operating system user trying to do insert action, he can do the action. BUT If "DEV" the developer operating system user trying to do insert action, the trigger must fire here to restrict this action.
Be noted also, i need this trigger not depend on any specific tool like Toad as any user can simply rename the exe file for toad then he can pass the trigger. At least, trigger must depend on (Operating system user & Action_type)
Region Code,Name,Surname,ID_Number 1,John,Doe,67 1,Sarah,Jason,45 2,Bob,Marley,69 3,Steven,Johnson,900 2,Harry,Potter,890 3,Sandy,Bay,567 3,Else,Taylor,789 .....
I have about over 100 region codes and each region would like to get their own data. I can manually do the extraction and create a new table for every region, but it's going to take too long.
Suppose two users (CONNECT and RESOURCE roles) A and B who work on the same project. How can B create synonyms of all tables of A without asking admin to do that? Of course, we assume that these users have the CREATE SYNONYM privilege. My problem is that B does not have access to user_tables of A, so he cannot obtain the list of A's tables to create synonyms.
is it possible to create tables using variables in pl/sql such as the following example which is actually in php. i would like to create a table dynamically.
$create_samp_table = CREATE TABLE $MCSCHEMA.".$samp_id." AS SELECT * FROM $MCSCHEMA.".$samp_src_table." WHERE ROWNUM = 0
I have 2 tables that doesn't have primary keys. These 2 tables have same number of rows. I want to create a new table from getting some columns from table1 and some columns from table 2. I want to combine first row from table1 and first row from table2.
Below is example
TABLE1
ACOL1 ACOL2 ACOL3 A1 A2 A3 B1 B2 B3 C1 C2 C3
TABLE2
BCOL1 BCOL2 BCOL3 11 12 13 21 22 23 31 32 33
COMBINED_TABLE
ACOL1 BCOL2 BCOL3 A1 12 13 B1 22 23 C1 32 33
I tried below query but no luck. It gives below error:
Query : create table COMBINED_TABLE AS select a.ACOL1, b.BCOL2, b.BCOL3 from (select ACOL1,rownum from TABLE1) a, (select BCOL2, BCOL3, rownum from TABLE2) b WHERE a.rownum = b.rownum
Error : ORA-01747:"invalid user.table.column, table.column, or column specification"
Here the SUB1 and SUB2 are "tables" and are similar in their structure. The "Main_Table" will be update dynamically and the no of rows in this table will vary.
Now my question , i need to create a view which will have all the rows from these tables ,in the current case it is something like
create or replace view sample as select * from SUB1 union all select * from SUB2
How can this be achived. I tried as shown below:
spool file_to_exe.sql select 'select * from ' || AA ||' union all ' from Main_table; spool off
i will end up in a union all "extra" , if i do like this.
I am getting an error when trying to run this DECLARE statement and I'm not sure why. I'm fairly new to PL/SQL and have looked up how to format a DECLARE statement and this seems right to me.
The error is stating "encountered the symbol "end-of-file" when expecting one of the following... " and is refering to the beginning of this statement.
select iloan_code,inst_due_date,paid_flag,late_fee,case late_fee when sysdate-inst_due_date between 1 and 10 then 10 when sysdate-inst_due_date > 10 and late_fee <>10 then 5 when sysdate-inst_due_date > 10 and late_fee = 10 then 15 else 0 end as new_late_fee from st_il_schedule where paid_flag='N'; i am getting error
Is there any difference between include program header before CREATE OR REPLACE PACKAGE statement and program header after CREATE OR REPLACE PACKAGE statement
I have a question. If i insert some values to a table and then write a create statement. But if the create statement gives me error (eg: table name already exist). And without commiting if i come out the session will the insert commit?
