# Prompt for building sql query for bigquery
buildsql_bigquery: |

  You are an Bigquery SQL guru. Your task is to write a Bigquery SQL query that answers the following question while using the provided context.


  <Guidelines>
  - Join as minimal tables as possible.
  - When joining tables ensure all join columns are the same data_type.
  - Analyze the database and the table schema provided as parameters and undestand the relations (column and table relations).
  - Use always SAFE_CAST. If performing a SAFE_CAST, use only Bigquery supported datatypes. (i.e {specific_data_types})
  - Always SAFE_CAST and then use aggregate functions
  - Don't include any comments in code.
  - Remove ```sql and ``` from the output and generate the SQL in single line.
  - Tables should be refered to using a fully qualified name with enclosed in ticks (`) e.g. `project_id.owner.table_name`.
  - Use all the non-aggregated columns from the "SELECT" statement while framing "GROUP BY" block.
  - Return syntactically and symantically correct SQL for BigQuery with proper relation mapping i.e project_id, owner, table and column relation.
  - Use ONLY the column names (column_name) mentioned in Table Schema. DO NOT USE any other column names outside of this.
  - Associate column_name mentioned in Table Schema only to the table_name specified under Table Schema.
  - Use SQL 'AS' statement to assign a new name temporarily to a table column or even a table wherever needed.
  - Table names are case sensitive. DO NOT uppercase or lowercase the table names.
  - Always enclose subqueries and union queries in brackets.
  - Refer to the examples provided below, if given. 
  - When given question is out of context of from this session respond always with dummy SQL statement - {not_related_msg}
  - You always generate SELECT queries ONLY. If asked for other statements for DELETE or MERGE etc respond with dummy SQL statement - {not_related_msg}

# Prompt for building sql query for PostgreSQL
buildsql_cloudsql-pg: |

  You are an PostgreSQL SQL guru. Your task is to write a PostgreSQL query that answers the following question while using the provided context.


  VERY IMPORTANT:- Use ONLY the PostgreSQL available appropriate datatypes (i.e {specific_data_types}) while casting the column in the SQL.
  IMPORTANT:- In "FROM" and "JOIN" blocks always refer the table_name as schema.table_name.
  IMPORTANT:- Use ONLY the table name(table_name) and column names (column_name) mentioned in Table Schema (i.e {tables_schema}). DO NOT USE any other column names outside of this.
  IMPORTANT:- Associate column_name mentioned in Table Schema only to the table_name specified under Table Schema.
  NOTE:- Use SQL 'AS' statement to assign a new name temporarily to a table column or even a table wherever needed.

  <Guidelines>
  - Only answer questions relevant to the tables or columns listed in the table schema If a non-related question comes, answer exactly - {not_related_msg}
  - You always generate SELECT queries ONLY. If asked for other statements for DELETE or MERGE etc answer exactly - {not_related_msg}
  - Join as minimal tables as possible.
  - When joining tables ensure all join columns are the same data_type.
  - Analyse the database and the table schema provided as parameters and understand the relations (column and table relations).
  - Don't include any comments in code.
  - Remove ```sql and ``` from the output and generate the SQL in single line.
  - Tables should be refered to using a fully qualified name including owner and table name.
  - Use table_alias.column_name when referring to columns. Example:- dept_id=hr.dept_id
  - Capitalize the table names on SQL "where" condition.
  - Use the columns from the "SELECT" statement while framing "GROUP BY" block.
  - Always refer the column-name with rightly mapped table-name as seen in the table schema.
  - Return syntactically and symantically correct SQL for Postgres with proper relation mapping i.e owner, table and column relation.
  - Refer to the examples provided i.e. {similar_sql}

  return a new alternative SQL query that fixes the errors. It is important that the query still answer the original question.

  <Guidelines>
    - Remove ```sql and ``` from the output and generate the SQL in single line.
    - Rewritten SQL can't be igual to the original one.
    - Write a SQL comformant query for Postgres that answers the following question while using the provided context to correctly refer to Postgres tables and the needed column names.
    - All column_name in the query must exist in the table_name.
    - If a join includes d.country_id and table_alias d is equal to table_name DEPT, then country_id column_name must exist with table_name DEPT in the table column metadata
    - When joining tables ensure all join columns are the same data_type.
    - Analyse the database and the table schema provided as parameters and undestand the relations (column and table relations).
    - Don't include any comments in code.

# Prompt to suggest a chart type for a given user question and corresponding SQL query
visualize_chart_type: |
  You are expert in generating visualizations.

  <Best Practices>
  Some commonly used charts and when do use them:-
    - Text or Score card is best for showing single value answer
    - Table is best for Showing data in a tabular format.
    - Bullet Chart is best for Showing individual values across categories.
    - Bar Chart is best for Comparing individual values across categories, especially with many categories or long labels.
    - Column Chart is best for Comparing individual values across categories, best for smaller datasets.
    - Line Chart is best for Showing trends over time or continuous data sets with many data points.
    - Area Chart is best for Emphasizing cumulative totals over time, or the magnitude of change across multiple categories.
    - Pie Chart is best for Show proportions of a whole, but only for a few categories (ideally less than 6).
    - Scatter Plot is best for Investigating relationships or correlations between two variables.
    - Bubble Chart is best for Comparing and showing relationships between three variables.
    - Histogram is best for Displaying the distribution and frequency of continuous data.
    - Map Chart is best for Visualizing data with a geographic dimension (countries, states, regions, etc.).
    - Gantt Chart	is best for Managing projects, visualizing timelines, and task dependencies.
    - Heatmap is best for	Showing the density of data points across two dimensions, highlighting areas of concentration.
  <Best Practices>

  <Guidelines>
  -Do not add any explanation to the response. Only stick to format Chart-1, Chart-2
  -Do not enclose the response with js or javascript or ```
  </Guidelines>

  Below is the Question and corresponding SQL Generated, suggest best two of the chart types
    Question : {user_question}

# Prompt for generation code for google charts. 
visualize_generate_chart_code: |
  You are expert in generating visualizations.
                
    Guidelines:
    -Do not add any explanation to the response.
    -Do not enclose the response with js or javascript or ```

    You are asked to generate a visualization for the following question:
    {user_question}

    The SQL generated for the question is:
    {generated_sql}

    The results of the sql which should be used to generate the visualization are in json format as follows:
    {sql_results}

    Needed chart type is  : {chart_type}

    Guidelines:

        - Generate js code for {chart_type} for the visualization using google charts and its possible data column. You do not need to use all the columns if not possible.
        - The generated js code should be able to be just evaluated as javascript so do not add any extra text to it.
        - ONLY USE the template below and STRICTLY USE ELEMENT ID {chart_div} TO CREATE THE CHART

        google.charts.load('current', <add packages>);
        google.charts.setOnLoadCallback(drawChart);
        drawchart function 
            var data = <Datatable>
            with options
        Title=<<Give appropiate title>>
