Pl/sql Procedure: Data reading of Clob field types in Oracle 11g the database column of the LOB type stores only the locator, which points to the storage location of the large object. manipulate LOB data with the Dbms_lob package. When reading data with an Oracle field type of CLOB column, only part of the following figure can be read: a full read of the data Pl/sql procedure for an Oracle field type of

The so-called clob can be seen as text, and the so-called blob can be seen as an image file Assume that the MySQL database has the following tables:Create Table Test (ID int primary key, TXT text, image BLOB ); If you want to read a text file and a binary file and store it in a database, you can use jdbctemplate, for example: Final file binaryfile = new file ("wish.jpg"); When creating a abstractlobcreatingpreparedstatementcallback object, a lobhandl

Some say that you want to upgrade the client, but I can use ORACLE 11.2.0.3 to export data. This problem exists in both oracle9 and 10. Please consider upgrading the client? Another solution without upgrading the client: OracleProblems may occur during cross-version exp export.Today I encountered the problem of exporting a table report exp-00003 containing the clob field. An Oracle bug was found online. The solution is to modify a System View. 1.

Table Schema: Create Table "sa". "tb_nclob"("ID" number (8, 0) not null enable,"Name" varchar2 (20 byte ),"Text" clob) C # code 　　 public static void InsertWithLob() { if (mConnection != null mConnection.State == ConnectionState.Open) { try { string sqlText="insert into tb_nclob(id,name,text)values(1,'test',:text)"; using (OracleCommand cmd=new OracleCommand(sqlText,mConn

This problem occurs because the concatenation of SQL statements is too long to cause, In general, Oracle SQL execution statements, English can not exceed 4000 characters, Chinese can not exceed 2000 characters, so once the content of the Clob field is more, there will be splicing of SQL is too long to cause the problem to occur. The simple workaround is to use a parameterized query to execute the SQL statement, the sample code is as follows OracleCon

Create Table products (Productid number (10) Not null,Name varchar2 (255 ),Description clob ); Query statement: Select T. productid, T. name from products t Where dbms_lob.instr (T. Description, 'aaa', 1, 1)> 0; In Oracle, you can use the instr function to determine whether a string contains specified characters. Its syntax is:Instr (sourcestring, deststring, start, appearposition ).Among them, sourcestring indicates the source string; deststring

When inserting or updating the CLOB field on the Oracle database, the INSERT into and UPDATE statements are directly spliced, and a ora-01704: String file too long The exception. That's because Oracle's implicit conversion mechanism is that Oracle converts strings to VARCHAR2 types by default, and this string has a length greater than 4000, so a ora-01704 error is reported. To put it more generally, the characters between the two single quotes cannot
