2499 error while executing a Oracle PL/SQL query

Question

Hi,
Im a newbie, using Oracle 10g enterprise edition, netbeans 6.5. Im unable to execute a SELECT query which contains multiple JOINS & UNIONS(lengthening upto 3800 chars) through code hence It flashes SP2-0027: Input is too long (> 2499 characters) - line ignored.
Earlier i had same problem while executing the query on the web interfaced query browser(isqlplus), sqlplus prompt.
Later on i found a Solution for such queries which are lengthening more than 2499 chars is either to break the query into multiple lines by pressing enter manually or to use M$ Word application (paste the query in a file and save it as a plain text filetype with insert line breaks option checked).
But what about the coding part now?
Please guide me through this.
Regards,
Peter

Answer 1

On sqlplus Oracle can't process lines over 2500 (cero is included on the counting) that's the reason why the error is displayed. To sort out this problem divide your query string into parts smaller than 2500 (2000 is recomended) and just add the next line between them:
CHR(10) || CHR(13)
Since this is gonna be read by the Oracle's engine and embedded into your query line, it will understand that every pair of CHR(10) || CHR(13) is a carriage return command and will drain the buffer processing every line with not errors.
Hope this helps
