I need to create probably two subqueries in which to reflect when a date changes. For instance, an account has a code and I need to reflect the the date the code changes...see sample below:
I have the one query which will return all of the dates, but I believe I need another query that will return only the dates that changed....can't seem to get that one to work at all. I believe once I do this then I can join the two queries together.
which contains multiple contact details for users of different types; type 1 is home, type 2 work etc. The following query returns the user's number and the latest home number for that user.
select user, details as latest_home_number from nc_test t where type = 1 and updated = (select max(updated) from nc_test t2 where t2.user = t.user and t2.type = t.type) order by t.user
However I am not very experienced with sql and I am not sure how to create a view which would contain the fields:
I am trying to validate a monthly report so was trying to write queries to get different criteria into one table. So my first query returns all the product,second query returns all the enrolled customers, 3rd query returns all the cancelled customers and 4th query returns all the newly enrolled for a month. Is there a way I can pass the first query results into 1st column, 2 query results into 2nd column, 3 query results into 3rd column and so on.
I tired writing the SQL several different ways and have spent a day on it and still cannot figure it out. I am using SQL Developer.
If multiple queries are run in parallel(at the same time) against a table or a set of tables (query referencing multiple tables), does it reduce the performance.
In other words is Oracle capable of reading (selecting from) the same table multiple times in parllel.
I am executing below two SQL's at a time in a .sql file and I want the total execution time of these two queries:-
set timing on; select 1 from dual; select 2 from dual;
The output of the above sql file is returning the results like below which is expected:-
1 ---------- 1
Elapsed: 00:00:00.01
2 ---------- 2
Elapsed: 00:00:00.00
I want the total execution time of the two SQL queries at a time, I mean post execution of the two queries I want to know the total execution time, in this case is execution case will be 00:00:00.01.
When working in MS Access, I can build parametric queries, where I can input the date field for example at run-time. How can I do something similar in SQL Oracle
Example
SELECT Sector.Date, Sector.RNC, Sector.Site, Sector.Cell,Sector.PSC FROM Sector WHERE Sector.Date=[Enter Date];
I have a scenario like, am having two databases DB1 and DB2 in different locations where I need to replicate some of the tables(around 10 to 15 tables) from DB1 to DB2(i.e. Whenever I update any table in DB1 it has to reflect in DB2.). Both DB1 and DB2 has the same database objects.
(DB version - Oracle 10g Release 10.2.0.4.0).
the steps how this can be done. Can it be done using Materialised View.
regarding grants given on object doesn't reflect on Oracle forms 6i.When my developer compiled the form the error throws object was not declared which means oracle form not able to access the object which is synonym of other table.Also we recreated the synonym and given grants from table owner and compiled form still throws same error,But i can able to select object from backend command but not from oracle forms.
grants reflect in oracle forms after we restart the database.
I have a simple question, hope it has a simple answer. I changed the default date format for a SCHEMA using a TRIGGER and AFTER LOGON, so it set the NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS'. It does work fine, however, the problem is when I connect using a client with JDBC driver. When using SQL PLUS I get the date in the format specified above YYYY-MM-DD HH24:MI:SS, however, when using a client (Aqua Data 6.5.8 I know it is kinda old) and SQuirrel SQL 3.4.0 I always get the date in the YYYY-MM-DD format. I started to think that the issue is with the JDBC because it works fine when I connect with SQLPLUS.
I have a question regarding this date format change. Would there be any impact to database if i change the NLS DATE FORMAT as above example (date and time) at database level /system level ?
our system has always been running on mysql database and recently we have switched to oracle. As the current system is coded using mysql query syntax, when i run this program using oracle database, i got a error. The language that I'm using is JSP.
this is the error message:
The following query could not run on oracle. To convert these mysql queries to oracle compatible queries.
SELECT productID,productName FROM products order by productName;
select newsID,newsDate,newsHeadLine1 from news order by newsDate Desc limit 3
SELECT fuji_products.productID, productName_Display FROM products,products_availability where products_availability.productID=products.productID and (product_status='enabled' or product_status='all') AND category='12'
SELECT catID, catSub1 from category where catSub = '"+ prodCat +"' AND catSub1 is not null group by catSub1 order by catSub1
I have data such as 'hours', 'date' when and employee worked on the project. What I need is to select the total amount of hours per month of March, April, May, etc...
I know how to select data per single date but wonder how to do it per multiple dates. How does one select total amount of hours per multiple date ranges (March, April...)?
Scenario 1 Query should check for priority record(25), if the start_date and end_date of that priority record is the max in that group, records will not have any split.output will be the same.
DC Store St Date End date Priority 955 3 1/1/2010 12/31/9999 25 966 3 4/5/2011 10/10/2011 50 977 3 10/12/2011 12/12/2012 100
output
DC store St Date End date Priority Rank 955 3 1/1/2010 12/31/9999 25 1 966 3 4/5/2011 10/10/2011 50 2 977 3 10/12/2011 12/12/2012 100 3
Scenario 2 If priority record is not covering the max range, then split the records as shown below,
1. during the time period 1/1/2011 & 4/30/2011 there were no other DC for that store so rank would be 1
2. the next range would be 5/1/2011 to 6/29/2011 we have 2 records in service so the record with low priortiy would be ranked 1 and second priority would be ranked 2
3. similarly, for 6/30/2011 to 10/1/2011 we have 3 records in service and it will be ranked accordingly on the priority.
DC Store St Date End date Priority 966 3 6/30/2011 10/1/2011 25 955 3 5/1/2011 11/30/2011 50 977 3 1/1/2011 12/31/2011 100
output
DC store St Date End date Priority Rank 977 3 1/1/2011 4/30/2011 100 1 955 3 5/1/2011 6/29/2011 50 1 977 3 5/1/2011 6/29/2011 100 2
[code]....
Scenario 3 This works similar to scenario 2
DC Store St Date End date Priority 966 3 2/1/2011 12/31/2011 25 955 3 1/1/2011 12/31/2012 50 977 3 5/1/2011 06/31/2011 100
output
DC store St Date End date Priority Rank 955 3 1/1/2011 1/31/2011 50 1 966 3 2/1/2011 12/31/2011 25 1 955 3 2/1/2011 12/31/2011 50 2 977 3 5/1/2011 6/30/2011 100 3 955 3 1/1/2012 12/31/2012 50 1
Note: Number of records in the input can vary and ther can be duplicates in the date interval
I have a table which contains the multiple records for single ID No. Now i have to select single record which contains the latest date. here is the structure Name

now i have to select below 2 rows how can write select qurie for this?
How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5 23 asdc 1 Location USA NM ABQ Four Seasons 87106 23 asdc 1 Stats 2300 91.7 8.2 85432 23 asdc 1 Audit 1996 June 17 1200 65 affc 2 Location USA TX AUS Hilton 92305 65 affc 2 Stats 5510 42.7 46 9999 65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime 23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200 65 affc 2 USA TX AUS Hilton 92305 5510 42.7 46 9999 1996 July 172 1100
- returning from the procedure 2 ref cursors containing result set of 2 queries - returning from the procedure 1 ref cursor containing result set of that 2 queries as one (with UNION ALL)?
I have to change some queries from SQL to Oracle but I couldn't convert these queries because they use some system tables in SQL that I don't know the equivalent Oracle tables. Following are SQL Queries
1. SELECT name, xtype FROM sysobjects WHERE xtype IN('U', 'V') AND name <> 'dtProperties' AND objectproperty(id, 'IsMSShipped') = 0 ORDER BY name
2. SELECT tS.name FROM sysobjects AS tS WHERE (tS.name IN (SELECT name FROM sysobjects WHERE xtype = 'U') AND xtype ='U') OR (tS.name IN (SELECT name FROM sysobjects WHERE xtype = 'V') AND xtype ='V')
3. SELECT o.name as TableName, c.name as FieldName, c.colid as Field_Ordinal, t.name as FieldType, c.length as FieldLength, c.prec as FieldPrecision, c.scale as FieldScale, c.isnullable, c.iscomputed, CASE WHEN c.status & 0x80 > 0 THEN 1 ELSE 0 END AS isidentity, columnproperty(o.id, c.name, 'IsRowGuidCol') as isrowguidcol FROM (sysobjects o JOIN syscolumns c ON o.id = c.id) JOIN systypes t On c.xtype = t.xtype WHERE o.xtype IN ('U', 'V') AND (t.xtype = t.xusertype)
On a tab page should be displayed the result of four indifferent queries, each based on a stored procedure.At the moment, the queries are processed serially, by the statements:
