How to return temporary CLOB instance from stored function in Pl/SQL?

旧巷老猫 提交于 2019-12-07 07:19:18
问题 My stored function creates temporary LOB instance using: Dbms_Lob.CreateTemporary(BUFFER, TRUE, Dbms_Lob.SESSION); where BUFFER is a local CLOB variable. After that the function fills BUFFER with some data and returns it. Duration parameter of Dbms_Lob.CreateTemporary in my case is Dbms_Lob.SESSION , but according to oracle documentation: The duration parameter passed to dbms_lob.createtemporary() is a hint . The duration of the new temp LOB is the same as the duration of the locator variable

Enter large content to oracle database

I have a .Net application connecting oracle database and want to enter more than 4000 character to a column in DB. I tried with CLOB still getting input string too long. I am using SQL query to enter data any help. Simplest way is using bind variable. Here is basic example: CREATE TABLE clob_table (val CLOB); void Main() { using (var connection = new OracleConnection("DATA SOURCE=hq_pdb_tcp;PASSWORD=oracle;USER ID=HUSQVIK")) { using (var transaction = new TransactionScope()) { connection.Open(); using (var command = connection.CreateCommand()) { command.CommandText = "INSERT INTO clob_table

Cannot save clob data type in database (Struts, Spring, Hibernate)

@Column(name="transpired") @Lob private String transpired; public String getTranspired() { return transpired; } public void setTranspired(String transpired) { this.transpired = transpired; } I tried using the following code in our model class. Transpired is a field with long text messages (reports). When viewing the "report", it retrieves the data from the database and displays it correctly in our UI. However, when I'm saving (upon editing or creating) the report, the field save on the database is (null). Any idea on how I could save long texts? We were using varchar2(4000) before but most

Update Clob column in Oracle

I have an table with name ABC which has CLOB data. I want to update the column to insert string in specific position in this Clob column. String to be inserted : <nv_pair> <name identifier="XYZ"></name> <value identifier="XYZ"></value> </nv_pair> Clob Data : <form> <nv_pair></nv_pair> <nv_pair></nv_pair><nv_pair></nv_pair><nv_pair></nv_pair></form> Position to be inserted : Just Before </form> Take a look at DBMS_LOB package. BTW, it might be worth exploring the possibility of abandoning CLOB and using Oracle's built-in XML capabilities (I'm not familiar with that, though). Depending on which

Do java.sql.Array/Blob/Clob types need to be “free()”ed?

允我心安 提交于 2019-12-05 21:52:06
问题 Do I need an explicit to call free() on Arrays, clobs etc... or will closing the ResultSet and/or Statement automatically take care of this? The javadoc doesn't say anything, so I assume that it's not necessary, but I would hate to make an incorrect assumption. Also, if its not necessary, is it a good idea if you're going to close the result set right away? I could see how it might help if you're not going to do so. 回答1: It depends on the Vendor and JDBC version you are using. As all databse

UTL_MATCH-like function to work with CLOB

泄露秘密 提交于 2019-12-05 20:37:49
My question is: Is there a UTL_MATCH -like function which works with a CLOB rather than a VARCHAR2 ? My specific problem is: I'm on an Oracle database. I have a bunch of pre-written queries which interface with Domo CenterView . The queries have variables in them defined by ${variableName} . I need to rewrite these queries. I didn't write the original so instead of figuring out what a good value for the variables should be I want to run the queries with the application and get what the query was from V$SQL . So my solution is: Do a UTL_MATCH on the queries with the variable stuff in it and V
