Summary

• Line 114: Fix typo MondoDB → MongoDB
• Line 140: Fix incorrect delimiter in CREATE KNOWLEDGE_BASE — semicolon should be a comma so metadata_columns is included in the statement
• Line 147: Fix broken WHERE clause — period after 'true' replaced with proper AND operator so revenue > 1000000 condition is applied

EntelligenceAI PR Summary

This PR corrects three errors in README.md to improve accuracy and validity of documented SQL syntax.

• Fixed typo: MondoDB → MongoDB
• Replaced semicolon with comma in CREATE KNOWLEDGE_BASE statement to fix invalid SQL syntax
• Corrected malformed WHERE clause by replacing a period with a newline and adding missing AND keyword to properly chain the revenue > 1000000 condition

Confidence Score: 5/5 - Safe to Merge

Safe to merge — this PR makes three straightforward documentation corrections in README.md with no code or logic changes. The fixes address a clear typo (MondoDB → MongoDB), a SQL syntax error (semicolon replaced with comma in the CREATE KNOWLEDGE_BASE statement), and a malformed WHERE clause (missing newline and AND keyword for the revenue > 1000000 condition). All changes improve the accuracy and validity of documented examples without introducing any risk.

Key Findings:

• The MondoDB → MongoDB typo fix is unambiguously correct and purely cosmetic in impact.
• The semicolon-to-comma correction in the CREATE KNOWLEDGE_BASE SQL example fixes genuinely invalid syntax that could mislead users trying to replicate the example.
• The WHERE clause correction — adding a newline and AND keyword before revenue > 1000000 — restores proper SQL chaining logic that was malformed in the original documentation.
• No automated review comments were generated, and there are no existing unresolved concerns; the PR scope is limited entirely to README.md documentation fixes.
