Final answer:
The PLS-00103 error in PL/SQL is a syntax error indicating unexpected symbols in the code. To resolve it, review the code for typos, check syntax thoroughly, ensure statement termination with semicolons, confirm the correctness of block openings and closings, and look for unmatched parentheses or quotation marks.
Step-by-step explanation:
The error PLS-00103: Encountered the symbol indicates that there is a syntax error in your PL/SQL code. This error typically occurs when there is an unexpected character, identifier, or end of file, and the compiler does not know how to proceed with parsing the code. To resolve this error, you should carefully check your code for typos, missing or extra characters, mismatched parentheses, or incorrect usage of PL/SQL syntax.
Here are some steps you can take to resolve PLS-00103 errors:
- Review the code line indicated by the error message and the lines above it, as sometimes the actual error might originate before the line indicated.
- Check that all statements are properly terminated with a semicolon (;).
- Ensure that all blocks are correctly opened with BEGIN and closed with END.
- Look for any unmatched parentheses or quotation marks.
- Comment out sections of code to isolate the error.
- Check for reserved words being used as variable or procedure names.
By systematically reviewing and correcting the code, you should be able to resolve the PLS-00103 error and compile your PL/SQL program successfully.
