Crystal Reports for Eclipse Designer Guide

SQL Query dialog box

This dialog box appears when you choose the "Show SQL Query" command from the Crystal Reports menu.
The SQL Query dialog box displays the SQL query that the program is sending to your SQL server.
The query can have one or more of the following parts:
  • SELECT
  • FROM
  • INNER JOIN
  • WHERE
  • ORDER BY
SELECT
SELECT lists all of the fields used in the report, including fields used in groups, formulas, totals, the sort order, the selection formula, and ranges.
For example, the following shows that the report is using the "CUSTOMER_NAME", "LAST_YEARS_SALES", "Order Date", and "Country" fields:
SELECT
"Customer"."CUSTOMER_NAME", "Customer"."Last Year's Sales",
"Orders"."Order Date", "Customer"."Country"
FROM
FROM lists all the tables used in the report, and each table name is followed by an alias name.
For example, the following shows that the report is using the Customer and Orders tables from the XTREME database, and in each case, the alias name is the same as the table name:
FROM
"XTREME"."dbo"."Customer" "Customer"
"XTREME"."dbo"."Orders" "Orders"
INNER JOIN
INNER JOIN specifies any links between tables.
For example, the following shows that the "Orders" and "Customer" tables are linked on the "Customer ID" field:
INNER JOIN
"XTREME"."dbo"."Orders" "Orders" ON
"Customer"."Customer ID"="Orders"."Customer ID"
WHERE
WHERE specifies the record filters for the report.
For example, the following shows that the report is filtered to display records from 'Canada', 'England', or 'USA':
WHERE
("Customer"."Country"='Canada' OR
"Customer"."Country"='England' OR
"Customer"."Country"='USA')
ORDER BY
ORDER BY sorts the data in alphabetic or numeric ascending or descending order.
For example, the following sorts the records in ascending order by the values that appear in the 'Customer.Country' and 'Customer.CUSTOMER_NAME' fields:
ORDER BY
"Customer"."Country", "Customer"."CUSTOMER_NAME"
