We have oracle 10 g and a table contains a clob field . The table size is getting increased day by day . We have decided to zip all the clob data inside the table except last 1 month records.
I have one table with clob field. The data in this field will contain string having transaction record data. Now I want to read data from this clob filed and insert different record in other oracle table.
example -> Data in clob field will be-> H|12|1233|fff|sss L|1234|gggg|tttt|yyyyyy|rrrrr L|1094|gggg|tttt|yyyyyy|rrrrr L|1344|gggg|tttt|yyyyyy|rrrrr L|1666|gggg|tttt|yyyyyy|rrrrr L|188|gggg|tttt|yyyyyy|rrrrr
I have one master table and one detail table. I want to insert record -> H|12|1233|fff|sss in master table and records-> L|1234|gggg|tttt|yyyyyy|rrrrr L|1094|gggg|tttt|yyyyyy|rrrrr L|1344|gggg|tttt|yyyyyy|rrrrr L|1666|gggg|tttt|yyyyyy|rrrrr L|188|gggg|tttt|yyyyyy|rrrrr in detail table.
End of excercise will redult-> 1 record in header and 5 records in detail table.
How can I insert xml to clob ? I'm taking from database clob making it in xml type and when I want to insert xml type into clob field it calls and error:
Error(316,43): PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got -
I am more of a C/C++ guy and relatively amateur in oracle. I have to update a table field from "Long" to "CLOB". I have planned to do a simple alter table, and as far as I know there won't be any issues.
Queries: 1. Although I have triple checked, is there any scenario under which there can be any data loss during the data type change? The data is very critical and no data loss can be entertained. 2. Is there any easy way to update all the related views without having to do so manually? 3. Any particular precautions I should take before introducing the change?
I am trying to insert complex HTML into a CLOB value in an Oracle table and keep running into various issues. The ORA errors I get include 0734, 0042 and 0552. The HTML I am inserting includes characters such as &, ', and *.
Here is an example of the SQL I am trying to run:
set DEFINE off' update table set message = '<HTML>TEST!@#$%</HTML>'; commit;
I need to pass a large data into one of the tables where the column is declared as CLOB before which I was checking with the sample code as below which is throwing an error.
I was trying to insert the CLOB data into the table as below.
create table t1 ( x number, y clob ); insert into t1(x) values (2) declare l_clob t1.y%type;
[code].....
The error I am getting is:
ORA-06502: PL/SQL: numeric or value error: invalid LOB locator specified: ORA-22275 ORA-06512: at "SYS.DBMS_LOB", line 833 ORA-06512: at line 161
i have a problem when i try to insert a large character string of nearly 1 lac characters (code of html) in a clob column of my test table, then i get an error "ORA-01704: string literal too long" , i didnot understand that why clob column is not storing this data.
I'm looking for a way to insert strings larger than 40.000 characters in a CLOB-field without geting the "ORA-01461: can bind a LONG value only for insert into a LONG column".
Something like this:
insert into MyClobTable(ID,Data) values ('101','A string containing more than 40000 characters...')
The problem is that a Java-application concatinates the string from a MSSQL-DB so I don't store the string in my oracle-DB. As far as I'm aware this means I can't chop my string in pieces and use declare to put the pieces in variables, right?
Below is an example I found but I don't think I can apply it on my case, correct?
SQL> CREATE TABLE myClob 2 (id NUMBER PRIMARY KEY, 3 clob_data CLOB);
I'm loading data from text file separated by TAB and i got the error below for some lines. Event the column is CLOB data type is there a limitation of the size of a CLOB data type. The error is:
Record 74: Rejected - Error on table _TEMP, column DEST. Field in data file exceeds maximum length
I'm using SQL Loader and the database is oracle 11g r2 on linux Red hat 5. Here are the line causing the error from my data file and my table description for test:
create table TEMP ( CODE VARCHAR2(100), DESC VARCHAR2(500), RATE FLOAT, INCREASE VARCHAR2(20), COUNTRY VARCHAR2(500), DEST CLOB, [code]........
I'm updating a large piece of legacy code that does the following type of insert:
INSERT INTO foo_temp (id, varchar2_column) SELECT id, varchar2_column FROM foo;
We're changing varchar2_column to clob_column to accommodate text entries > 4000 characters. So I want to change the insert statement to something like:
INSERT INTO foo_temp (id, clob_column) SELECT id, clob_column FROM foo;
This doesn't work, since clob_column stores the location of each text entry, rather than the actual content. But is there some way that I can achieve the insert with one call to a select statement, or do I need to select each individual record in foo, open the clob_column value, read it into a local variable and then write the content to the matching record in foo_temp?
I am only able to extract only 4000 characters from the clob column "DESCRIPTION".how to get more characters or max for that column with the same query concept?
I have a "simple" query that needs to extract all of the XML messages stored in a CLOB column in a table for a data deidentification project. This query
select c.cc_data_area.getClobVal() as cc_xml from ci_cc c;
This query returns an ORA-22806: not an object or REF
cc_data_area is the clob column, and contains messages longer than 4000 characters.
I have a table that contains a CLOB column with pseudo-XML in it. I want to keep this data in an XMLType column so that I can leverage some of Oracle's built-in XML features to parse it more easily.
The source table is defined as: CREATE TABLE "TSS_SRM_CBEBRE_LOGS_V" ( "INCIDENT_ID" NUMBER, "EVENT_TYPE" VARCHAR2(100 BYTE) NOT NULL ENABLE, "EVENT_KEY" VARCHAR2(100 BYTE), "CREATION_DATE" TIMESTAMP (6) NOT NULL ENABLE, "CREATED_BY" VARCHAR2(100 BYTE) NOT NULL ENABLE, "LOG_MSG" CLOB);
The target (for testing this problem) table is defined as: CREATE TABLE "TESTME" ( "LOG_MSG" "XMLTYPE") My query is: insert /*+ APPEND */ into testme ("LOG_MSG")select XMLTYPE.createXML("LOG_MSG") as LOG_MSG from "TSS_SRM_CBEBRE_LOGS_V" b; In SQL*Developer, my error is: Error report:SQL Error: No more data to read from socket In SQL*PLUS and Toad, my error is: ORA-03113: end-of-file on communication channelProcess ID: 13903Session ID: 414 Serial number: 32739
Example: I want to search 'Hello world' for the first instance of the letter 'o' starting from the end, backwards.As you can see, result for DBMS_LOB.instr is null when entered -1 for offset.
select DBMS_LOB.instr('Hello world','o',-1,1) lob_i, instr('Hello world','o',-1,1) std_i from dual;
I need to copy records from a working table to a history table. I have the following sql statement
insert into test.history (equip_ID, state, manufacturer, install_year, capacity, group_ID, Test_status) select (equip_ID, state, manufacturer, install_year, capacity, group_ID, Test_status from test.info_AP
Table test.history has one more field in it called test_year. I need to fill this field when I do the insert. Can't use an after update trigger as the field is currently set to not allow nulls.
I have three tables. One for projects, one for volunteers, and a bridge entity for the many to many relationship between the Project and Volunteer.
In Project table, I have a field called, Volunteers_currently_signed_up, which means the number of volunteers currently signed up to participate in a project.
When I add an entry to my bridge entity which is composed of Volunteer_ID and Project_ID, I want the Volunteers_currently_signed_up to increment by 1, where the Project_ID in the bridge entity corresponds to that in Project.
I have very very little PL/SQL, and this is my amateur attempt so far:
CREATE OR REPLACE trigger "BI_Volunteers_currently_signed_up" BEFORE INSERT OR UPDATE ON Volunteers_in_project for each row WHERE Volunteers_in_project.Project_ID=Project.Project_ID; begin Project.Volunteers_currently_signed_up += 1; end; /
I need to select a count of records where a field (call it widget) is the same, so i need all records where widgets are distinct. So it would be like asking for a distinct in a where clause. Not having much SQL experience this is a difficulty for me.
lets see .. so a count of records where widget = widget or something along those lines.
