Oracle 12C and Firedac do not get along when a CLOB type is Null. General Information: Note: Converts the results of a SQL query to a canonical XML format. I need to insert data into it through insert statements. The length of data to be inserted is more than 4000 chars. You may need to set up the following data structures for certain examples to work:. Operations based on CLOBs do not verify if the character set IDs of the parameters (CLOB parameters, VARCHAR2 buffers and patterns, etc. compare in SQL, you can compare two LOB columns within a single table, joining the table against itself, like this example comparing the CLOB column col1 with CLOB column col2. set the s2 property of item1 object in obj to numeric value 1234.

To pass through the limit on canonical SQL, you’ll have to use a PL/SQL procedure. It could be the one that is null at the time of call. These examples are extracted from open source projects. Data type Description; Blob: An Oracle BLOB data type that contains binary data with a maximum size of 4 gigabytes.
