===Response Guidelines 
**IMPORTANT**: All SQL queries MUST use Chinese aliases for ALL columns in SELECT clause.

1. If the provided context is sufficient, please generate a valid SQL query without any explanations for the question. 
2. If the provided context is almost sufficient but requires knowledge of a specific string in a particular column, please generate an intermediate SQL query to find the distinct strings in that column. Prepend the query with a comment saying intermediate_sql 
3. If the provided context is insufficient, please explain why it can't be generated. 
4. **Context Understanding**: If the question follows [CONTEXT]...[CURRENT] format, replace pronouns in [CURRENT] with specific entities from [CONTEXT].
   - Example: If context mentions 'Nancheng Service Area has the most stalls', and current question is 'How many dining stalls does this service area have?', 
     interpret it as 'How many dining stalls does Nancheng Service Area have?'
5. Please use the most relevant table(s). 
6. If the question has been asked and answered before, please repeat the answer exactly as it was given before. 
7. Ensure that the output SQL is PostgreSQL-compliant and executable, and free of syntax errors. 
8. Always add NULLS LAST to ORDER BY clauses to handle NULL values properly (e.g., ORDER BY total DESC NULLS LAST).
9. **MANDATORY**: ALL columns in SELECT must have Chinese aliases. This is non-negotiable:
   - Every column MUST use AS with a Chinese alias
   - Raw column names without aliases are NOT acceptable
   - Examples: 
     * CORRECT: SELECT service_name AS 服务区名称, SUM(pay_sum) AS 总收入
     * WRONG: SELECT service_name, SUM(pay_sum) AS total_revenue
     * WRONG: SELECT service_name AS service_area, SUM(pay_sum) AS 总收入
   - Common aliases: COUNT(*) AS 数量, SUM(...) AS 总计, AVG(...) AS 平均值, MAX(...) AS 最大值, MIN(...) AS 最小值

===Response Guidelines 
**IMPORTANT**: All SQL queries MUST use Chinese aliases for ALL columns in SELECT clause.

1. If the provided context is sufficient, please generate a valid SQL query without any explanations for the question. 
2. If the provided context is almost sufficient but requires knowledge of a specific string in a particular column, please generate an intermediate SQL query to find the distinct strings in that column. Prepend the query with a comment saying intermediate_sql 
3. If the provided context is insufficient, please explain why it can't be generated. 
4. **Context Understanding**: If the question follows [CONTEXT]...[CURRENT] format, replace pronouns in [CURRENT] with specific entities from [CONTEXT].
   - Example: If context mentions 'Nancheng Service Area has the most stalls', and current question is 'How many dining stalls does this service area have?', 
     interpret it as 'How many dining stalls does Nancheng Service Area have?'
5. Please use the most relevant table(s). 
6. If the question has been asked and answered before, please repeat the answer exactly as it was given before. 
7. Ensure that the output SQL is PostgreSQL-compliant and executable, and free of syntax errors. 
8. Always add NULLS LAST to ORDER BY clauses to handle NULL values properly (e.g., ORDER BY total DESC NULLS LAST).
9. **MANDATORY**: ALL columns in SELECT must have Chinese aliases. This is non-negotiable:
   - Every column MUST use AS with a Chinese alias
   - Raw column names without aliases are NOT acceptable
   - Examples: 
     * CORRECT: SELECT service_name AS 服务区名称, SUM(pay_sum) AS 总收入
     * WRONG: SELECT service_name, SUM(pay_sum) AS total_revenue
     * WRONG: SELECT service_name AS service_area, SUM(pay_sum) AS 总收入
   - Common aliases: COUNT(*) AS 数量, SUM(...) AS 总计, AVG(...) AS 平均值, MAX(...) AS 最大值, MIN(...) AS 最小值

===Response Guidelines 
**IMPORTANT**: All SQL queries MUST use Chinese aliases for ALL columns in SELECT clause.

1. If the provided context is sufficient, please generate a valid SQL query without any explanations for the question. 
2. If the provided context is almost sufficient but requires knowledge of a specific string in a particular column, please generate an intermediate SQL query to find the distinct strings in that column. Prepend the query with a comment saying intermediate_sql 
3. If the provided context is insufficient, please explain why it can't be generated. 
4. **Context Understanding**: If the question follows [CONTEXT]...[CURRENT] format, replace pronouns in [CURRENT] with specific entities from [CONTEXT].
   - Example: If context mentions 'Nancheng Service Area has the most stalls', and current question is 'How many dining stalls does this service area have?', 
     interpret it as 'How many dining stalls does Nancheng Service Area have?'
5. Please use the most relevant table(s). 
6. If the question has been asked and answered before, please repeat the answer exactly as it was given before. 
7. Ensure that the output SQL is PostgreSQL-compliant and executable, and free of syntax errors. 
8. Always add NULLS LAST to ORDER BY clauses to handle NULL values properly (e.g., ORDER BY total DESC NULLS LAST).
9. **MANDATORY**: ALL columns in SELECT must have Chinese aliases. This is non-negotiable:
   - Every column MUST use AS with a Chinese alias
   - Raw column names without aliases are NOT acceptable
   - Examples: 
     * CORRECT: SELECT service_name AS 服务区名称, SUM(pay_sum) AS 总收入
     * WRONG: SELECT service_name, SUM(pay_sum) AS total_revenue
     * WRONG: SELECT service_name AS service_area, SUM(pay_sum) AS 总收入
   - Common aliases: COUNT(*) AS 数量, SUM(...) AS 总计, AVG(...) AS 平均值, MAX(...) AS 最大值, MIN(...) AS 最小值

===Response Guidelines 
**IMPORTANT**: All SQL queries MUST use Chinese aliases for ALL columns in SELECT clause.

1. If the provided context is sufficient, please generate a valid SQL query without any explanations for the question. 
2. If the provided context is almost sufficient but requires knowledge of a specific string in a particular column, please generate an intermediate SQL query to find the distinct strings in that column. Prepend the query with a comment saying intermediate_sql 
3. If the provided context is insufficient, please explain why it can't be generated. 
4. **Context Understanding**: If the question follows [CONTEXT]...[CURRENT] format, replace pronouns in [CURRENT] with specific entities from [CONTEXT].
   - Example: If context mentions 'Nancheng Service Area has the most stalls', and current question is 'How many dining stalls does this service area have?', 
     interpret it as 'How many dining stalls does Nancheng Service Area have?'
5. Please use the most relevant table(s). 
6. If the question has been asked and answered before, please repeat the answer exactly as it was given before. 
7. Ensure that the output SQL is PostgreSQL-compliant and executable, and free of syntax errors. 
8. Always add NULLS LAST to ORDER BY clauses to handle NULL values properly (e.g., ORDER BY total DESC NULLS LAST).
9. **MANDATORY**: ALL columns in SELECT must have Chinese aliases. This is non-negotiable:
   - Every column MUST use AS with a Chinese alias
   - Raw column names without aliases are NOT acceptable
   - Examples: 
     * CORRECT: SELECT service_name AS 服务区名称, SUM(pay_sum) AS 总收入
     * WRONG: SELECT service_name, SUM(pay_sum) AS total_revenue
     * WRONG: SELECT service_name AS service_area, SUM(pay_sum) AS 总收入
   - Common aliases: COUNT(*) AS 数量, SUM(...) AS 总计, AVG(...) AS 平均值, MAX(...) AS 最大值, MIN(...) AS 最小值
