clob

问题 From Java I am doing the following query on DB2: SELECT * FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ? The field TRANSACTION_ID is a VARCHAR of length 32. I set the parameter in the preparedStatement using the setString method. I get the error: com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-270, SQLSTATE=42997, SQLERRMC=63, DRIVER=3.59.81 at com.ibm.db2.jcc.am.dd.a(dd.java:676) at com.ibm.db2.jcc.am.dd.a(dd.java:60) at com.ibm.db2.jcc.am.dd.a(dd.java:127) at com.ibm

问题 I'm investigating an interesting performance issue, where there are no calls to java.sql.Clob.free() on a frequently used resource. This method on Clob was introduced in Java 6 / JDBC 4, so it might well be that this is actually a regression introduced when upgrading from JDBC 3 to JDBC 4. Is this a known issue in the Oracle JDBC driver? Can it be said that before, Clobs somehow magically freed themselves, whereas with JDBC 4, they MUST be freed manually? Or is there a driver setting that can

问题 I have the following query: select id from table1 where some_func(?) = 1; where some_func is a function which allows its arguments to be either VARCHAR2 or CLOB, and ? is some string, which could be really long. I am trying to use the following code to bind variables: stmt.setObject(i+1, obj); but in case of string.length() > 4000 I get the following error: java.sql.SQLException: ORA-01460: unimplemented or unreasonable conversion requested for an obvious reason: the VARCHAR2 size limit is

问题 My question is: How do you get around the ORA-01704: string literal too long error when inserting (or doing anything in queries) with CLOB s? I want to have a query like this: INSERT ALL INTO mytable VALUES ('clob1') INTO mytable VALUES ('clob2') --some of these clobs are more than 4000 characters... INTO mytable VALUES ('clob3') SELECT * FROM dual; When I try it with actual values though I get ORA-01704: string literal too long back. This is pretty obvious, but how do I insert clobs (or

问题 I need to write an XML file content into oracle database where the column is of CLOB datatype. How will I do that? 回答1: OUTDATED See Lukas Eder's answer below. With about 100 lines of code ;-) Here is an example. The main point: Unlike with other JDBC drivers, the one from Oracle doesn't support using Reader and InputStream as parameters of an INSERT . Instead, you must SELECT the CLOB column FOR UPDATE and then write into the ResultSet I suggest that you move this code into a helper method

问题 I want to insert large size of data that character length is more than 10,000. I used CLOB data type to each column. I can't insert/update that large data it shows following error: ORA-01704: string literal too long My code insert into table1 value(1,'values>10000'); 回答1: You'll have to assign the value to a variable & use the variable to insert the data DECLARE v_long_text CLOB; BEGIN v_long_text := 'your long string of text'; INSERT INTO table VALUES (1, v_long_text); END; To make it clear:

问题 The problem is, how to transfer CLOB data from one source database to another Oracle database, having DBLinks. Oracle cannot transfer CLOB data using DBLinks so what kind of solution we can have apart from: extending fields in Oracle to Varchar2 32.767 characters (new feature of Oracle 12). 回答1: At first you need temporary table: create global temporary table TBL_TMP_CLOB ( c_clob CLOB ) At second use 'Insert from Select': INSERT INTO schema.remote_table@dblink(rem_clob) SELECT * FROM TBL_TMP

问题 I have an .xml file that I am trying to load into a clob field in an Oracle table. The .xml file is 49 lines in length. When I run my sqlloader cntl, the entire .xml file gets loaded into my table as a new row, 49 times. I am using Oracle 11.2.0.3 What am I doing wrong? CREATE TABLE "LEAD_REPORTING_CLOB" ("SHARED_XML" CLOB); my cntl: LOAD DATA INFILE * REPLACE INTO TABLE LEAD_REPORTING_CLOB TRAILING NULLCOLS ( SHARED_XML LOBFILE(CONSTANT '/export/RFD/Lead_Reports/LEADRPT.xml') TERMINATED BY

问题 I recently upgraded from Hibernate 3.x to 4.x, I used this article as a reference. I am facing a problem when inserting Clob data as a String to the database, my application runs on (Oracle - MySql - MSSQL) databases. This is my hibernate domain: @Lob @Column(name = "LargeText" ) public String getLargeText() { return largeText; } public void setLargeText(String largeText) { this.largeText = largeText; } When I try to insert the object to the database, this exception is being thrown: SEVERE:

问题 i m using Oracle 9i. I m fetching data from a cursor into an array : FETCH contract_cur BULK COLLECT INTO l_contract ; But now i want to "convert" this l_contract into a CLOB variable l_clob Is there an easy way to do that? Or otherwise, how do i convertthe rows from a SELECT statement into one single CLOB Variable ? thanks EDIT : i forgot to mention its an array of %ROWTYPE, not just one column. 回答1: What an ugly thing to do. Is it all character data, or do you have numeric and/or date/time
