WalkthroughThe Oracle plugin now removes semicolons only outside protected SQL constructs. Non-prepared queries also receive this processing. Null handling and unit tests were added for query parsing and PL/SQL detection. ChangesOracle semicolon handling
Priority: ⬆️ High Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Bug fix · Severity of issue fixed: High Suggested reviewers: Merge Risk: 🔵 Low · up to Some non-prepared Oracle queries containing PL/SQL keywords in protected text can retain a trailing semicolon and fail through JDBC. The case is narrow but should be corrected or explicitly accepted before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Make isPLSQL ignore literals and comments.
PLSQL_MATCH_REGEX is applied with find() to the full lowercased query. Therefore, SELECT 'begin ' FROM dual; matches \bbegin\b\s inside the string. The non-prepared branch then skips removeSemicolonFromQuery, so the unchanged query reaches Statement.execute. Oracle JDBC can reject the trailing semicolon for normal SQL. Detect PL/SQL from the first significant token, or make isPLSQL quote- and comment-aware. Add a regression test for the non-prepared path.

Fixes #42267
Description
The Oracle plugin strips semicolons from queries before executing non-PL/SQL statements via
removeSemicolonFromQuery(String query)(because Oracle JDBC rejects statements with trailing semicolons).Problem
Previously,
removeSemicolonFromQueryused a naivequery.replaceAll(";", ""):This removed every semicolon in the query, including semicolons inside:
'Error; check connection')q'[first; second]')"my;column")-- comment;and/* block; comment */)This caused silent data corruption (e.g.
'Error; check'stored as'Error check') and broke filter comparisons inWHEREclauses.Solution
removeSemicolonFromQueryto scan the query character by character, tracking the parser state (single-quoted strings, escaped quotes'', Oracle Q-quotesq'[...]'/q'(...)'/q'{...}'/q'<...>'/q'#...#', double-quoted identifiers"...", line comments-- ..., and block comments/* ... */).isPLSQL.OraclePlugin.javaas well.OracleExecuteUtilsTest.javacovering all edge cases (string literals with semicolons, escaped quotes, Q-quotes, comments, delimited identifiers, trailing semicolons, and PL/SQL detection).Automation
