ORA-00933: SQL Command Not Properly Ended - Troubleshooting Guide

The ORA-00933 error in Oracle indicates that your SQL command hasn't ended properly. This could be due to several reasons:

1. Syntax Errors: Your SQL statement might have a syntax error. Check for missing commas, mismatched parentheses, or other grammatical mistakes.

2. Incorrect Command Order: Some SQL commands require a specific order. For example, when using INSERT INTO, you must specify the target table, followed by the columns and values to be inserted. Ensure your command sequence is correct.

3. Statement Length: Certain database management systems have limitations on the length of individual SQL statements. If your INSERT INTO statement exceeds this limit, it can lead to this error. Try splitting the statement into smaller, separate commands.

4. Data Type Mismatch: Make sure the values you're inserting match the data types of the corresponding columns. Data type mismatches can cause this error.

5. Non-Existent Tables or Columns: If your INSERT INTO statement references a non-existent table or column, the error will occur. Double-check your table and column names.

If these suggestions don't resolve the issue, provide the complete SQL statement and the relevant table structure for more effective assistance.
