    Question

    What are some of the more commonly used SQL Keywords found in Voyager Prepackage Access Reports?

    Answer

    SELECT List the fields you want
    DISTINCT Keep only unique values
    FROM List the tables from which to get data
    INNER JOIN Standard join -- fields in both tables are equal
    OUTER JOIN Special join -- if no matching value in 2nd table, keep record anyway
    INTO Make a table from the results of your query
    AS Rename a field or a table within the query
    ORDER BY Sort the results by these fields, left to right
    ASC Do the sort in ascending order (default)
    DESC Do the sort in descending order
    GROUP BY Aggregate the records where these fields are the same
    WHERE Keep only records that match these criteria
    AND Additional WHERE criteria
    HAVING When you use GROUP BY, the WHEREs turn to HAVINGs !?!
    UNION Combine two tables into one long table
    UNION ALL Do a UNION, but don’t delete duplicate records (this is a “gotcha”)

    Access SQL Example

    SELECT DISTINCT 
    PATRON.LAST_NAME AS TOO_MANY, 
    PATRON.FIRST_NAME, CIRC_TRANSACTIONS.CURRENT_DUE_DATE
    FROM PATRON INNER JOIN CIRC_TRANSACTIONS ON PATRON.PATRON_ID = CIRC_TRANSACTIONS.PATRON_ID
    WHERE (((CIRC_TRANSACTIONS.[CURRENT_DUE_DATE])<Date()) AND ((CIRC_TRANSACTIONS.[OVERDUE_NOTICE_COUNT])>"1"))
    ORDER BY CIRC_TRANSACTIONS.CURRENT_DUE_DATE DESC;

     

    Additional Information

    The Voyager server uses SQL*Plus, which is different from Access SQL.  They are not compatible.

     

    Constructing custom SQL queries by request and troubleshooting unexpected results from customer-created SQL queries falls outside the scope of Support. The above has been posted for informational purposes.  Voyager-L and Developer Network are useful resources for finding helpful custom SQL or obtaining assistance from peers in troubleshooting custom queries.
