As you review the statements and clauses below, note that brackets identify optional information.Include a bracketed item if you want to select more specific data.

Note: If you don't know the SQL programming language, you can use QueryLink by clicking the Queries button in FinancialLink, EmployeeLink, Student/ Class Info tools, and DataLink.

  • select [all | distinct]
    A select statement queries the database and retrieves selected data that match the specified criteria.

  • field1 [,field2, 3, 4, etc.]
    The field name specifies the particular fields that contain the data.

    Note: You can find field and data table names in the Data Models section of DataLink.

  • Required:
    • from table1[, table2]
      The from clause specifies the table(s) that contain the data.
    Optional:
  • where conditions
    The where clause specifies the selection condition(s) by which data is retrieved.
  • order by [column-list]
    The order by clause specifies the ordering or sorting of rows.
  • group by [column-list]
    The group by clause groups the resulting rows in sets.
  • having conditions
    The having clause allows a search condition and is used with the group by clause.

  • Here's a sample statement:

    select [all | distinct] field1[,field2]
    from table1[,table2]
    [where conditions]
    [group by field-list]
    [having conditions]
    [order by field-list]

  • The example below shows SQL being used in the SQL Executer to produce a phone list of all ACT staff by last name.
  • The list will show last names, first names, phone extensions, and e-mail addresses.
