Missing Comma in SELECT Column List
Syntax error: unexpected identifier 'email' near 'user_id'In SQL, every column in the SELECT list must be separated by a comma. Without it, the query engine treats the next column name as a column alias or throws an unexpected token exception.
SELECT
user_id
email,
created_at
FROM users
WHERE is_active = 1;SELECT
user_id,
email,
created_at
FROM users
WHERE is_active = 1;الحل البرمجي: Insert a comma (,) after user_id so each column is distinctly evaluated by the SQL parser.
