- Query Instructions
-
-
- The Query program will allow you to produce a report based on
- your selection, sorting and formatting specifications. Upon
- entry, you will be presented with a data dictionary and string
- gadgets for entering your record selection criteria, sort
- sequence and output report format.
-
- The data dictionary presents you with a list of data names that
- can be used to display or print values contained in the database.
-
- The Select string gadget will allow you to specify some selection
- criteria to be used to determine which database entries will be
- included in you output display or report. For example,
-
- SELECT:
- (Payee = "Allstate" or "State Farm") and Amount > 100.00"
-
- specifies that the database is to be searched for Payees with the
- name of "Allstate" or "State Farm" with an Amount > $100.00.
- Remember that in order to enter data into a string gadget you
- must first position the pointer within the gadget and depress the
- left button on the mouse. Note that the Select parameters
- contain parentheses to prevent ambiguities. If there is a
- possibility that the key word or phrase you are looking for
- contains occurrences with both upper and lower case letters, you
- must check for both, e.g., "Allstate" or "allstate". Another
- method is to use the wild character, e.g., "?llstate".
-
- The Sort string gadget will allow you to specify the sequence in
- which the selected records are to be displayed or printed. For
- example,
-
- SORT:
- Date
-
- specifies that the selected database entries are to be sorted in
- Date sequence. Only one sort field may be specified. To sort
- the field as a date, enter cdate(Date). This option will make
- the years sort in the correct order.
-
- The Report string gadget will allow you to specify the format of
- the output display or report. For example,
-
- REPORT:
- Date, col 13, Type, col 18, Payee, col 44, Amount
-
- specifies that the Date, Type, Payee and Amount for the selected
- records are to be displayed. Further, it is specified that the
- Date is to be displayed beginning in column 1, the Type in column
- 13, the Payee in column 18 and Amount in column 44. The Report
- specification parameters may be very simple or very complex
- depending upon the skill of the user. Upon entering the Query
- program, you will find that the Report string gadget already
- contains some parameters. These parameters have been designed to
- simply list and total the selected transactions. You may use
- these parameters or enter your customized report specifications.
- To erase the content on the Report string gadget, first select
- the gadget and then depress Right AMIGA - X. To undo (cancel)
- the last editing change to the string, depress Right AMIGA - Q.
- The Report specification parameters can be classified as either
- describing "when to do it" or "what to do".
-
- When To Do It:
-
- page_top - specifies that subsequent functions are to be
- executed at the top each printed page or screen.
-
- page_bottom - specifies that subsequent functions are to
- the executed at the bottom of each printed page or
- screen.
-
- report_top - specifies that subsequent functions are to
- be executed only at the beginning of the output report.
-
- report_bottom - specifies that subsequent functions are
- to executed only at the end of the report.
-
- top(<data-name>) - specifies that subsequent functions
- are to be executed after there has been a change in the
- content of <data-name>. For example, top(Payee).
- Normally, the specified data-name will be the same as
- the sort sequence.
-
- bottom(<data-name>) - specifies that subsequent
- functions are to be executed before there is a change in
- the content of data-name. For example, bottom(EC).
-
- detail - specifies that the subsequent functions are to
- be executed for each selected database entry.
-
- What To Do:
-
- print - specifies that all output is to be routed to the
- printer. Default values for tm, bm and bod are set to
- 4, 8, and 54 respectively.
-
- display - specifies that all output is to be routed to
- the screen. "Display" is the output default. Default
- values for tm, bm and bod are set to 0, 0, and 22
- respectively.
-
- tm nn - sets the top margin for the output display or
- report to the value specified by nn.
-
- bm nn - sets the bottom margin for the output display or
- report to the value specified by nn.
-
- bod nn - sets the body of the output display or report
- to the value specified by nn. The sum of tm, bm and bod
- must equal the desired page length.
-
- <data-name> - causes the specified data name to be
- printed or displayed. For example, "Payee" is a
- data-name.
-
- "literal" - causes the specified literal to be printed
- or displayed. For example, "The result is:" is a
- literal.
-
- trim(<data-name>) - caused the specified data name to be
- printed or displayed after all trailing spaces have been
- eliminated. For example, "trim(Payee)".
-
- total(<data-name>) - specifies that the summed value of
- <data-name> is to be printed or displayed. An numeric
- data item from the dictionary or a numeric literal must
- be substituted for <data-name>. For example,
- "total(Amount)". "total(1)" can be used to provide a
- count of the transactions.
-
- cum(<data-name>) - same as "total" except that the
- accumulator is not reset after displaying the total.
- This function is used to produce a running balance.
-
- spacer nn - causes nn spaces to be inserted between
- output data items. The default is 1.
-
- col nn - causes the next specified data item to be
- displayed or printed in the column specified by nn.
-
- skip n - causes n lines to be skipped before displaying
- or printing the next data item. If n is not provided, 1
- is assumed.
-
- pause - causes a pause in the output process until a key
- (any key) is depressed.
-
- eject - if "print" has been specified, this command
- causes the paper to be ejected to the top of the next
- page; otherwise, the screen will be cleared.
-
-
- EDITING MASKS
-
- Numeric Editing Masks may be used to cause predefined
- characters to be imbedded within displayed or printed
- numeric items. Numeric items are identified in the data
- dictionary with the character "n" following the data
- name. The masks must be constructed as an alphanumeric
- literal whose first character is "%". If the second
- character of the mask literal is other than a numeric
- character, that character will be placed in the next
- left most position before the resulting edited numeric
- value.
-
- Examples:
-
- Input Values Mask Output
-
- 01000 "%9,999" 1,000
-
- 25245 "%$99,999" $25,245
-
- -5643 "%$999,999" $-5,643
-
- Alphanumeric Editing Masks may be used to cause
- predefined characters to be imbedded within displayed or
- printed alphanumeric items. Alphanumeric items are
- identified in the data dictionary with the character "c"
- following the data name. The mask must be constructed
- as an alphanumeric literal whose first character is "%".
-
- Examples:
-
- Input Values Mask Output
-
- 123456789 "%@@@-@@-@@@@" 123-45-6789
-
- 102786 "%@@/@@/@@" 10/27/86
-
-
- Here is an example of a more complex query construction:
-
-
- SELECT:
- (EC = "UE" or "UW" or "UP") and Date = "????86" and Type = "C"
-
-
- SORT:
- EC
-
-
- REPORT:
- print Date Payee EC Amount "%9,999,999.99" bottom(EC)
- total(Amount) "%9,999,999.99"
-
-
- This query selects transactions with Expense Codes of "UE" or
- "UW" or "UP" that have a Date ending with "86" that also have a
- Type of "C". Note that the question mark (?) is used as a wild
- character, i.e., it is used to denote "any character". The
- output report is to be printed and will contain the Date, Payee,
- Expense Code and Amount. A total will be printed when there has
- been a change in the expense code.
-
- Rules:
-
- (1) The Select statement may contain these operators:
-
- = Equal to
- <> Unequal to
- < Less than
- > Greater than
- <= Less than or equal to
- >= Greater than or equal to
-
- (2) The field on the left side of the operator must be a
- data name from the dictionary.
-
- (3) The field on the right side of the operator may be
- either a data name or literal. Literals must be enclosed in
- double quotes.
-
- (4) In the case of equal and unequal, the data name on the
- left side of the operator is searched for any occurrences of the
- data specified on the right of the operator.
-
- (5) The length of the item to the right of the operator may
- not be greater than the length of the item to the left of the
- operator.
-
- (6) When used in a literal, the "?" is wild. For example,
- to select all records in the database enter:
-
- SELECT:
- Date = "?"
-
- (7) Commas may used to improve readability; otherwise, they
- serve no useful purpose.
-
- (8) All data names must be capitalized. All other commands
- must be in lower case.
-
- If your printer carriage is 80 columns in width, try setting your
- printer preferences for compressed mode in order to print reports
- that are greater than 80 characters in width. Also, if your
- printed output does not have the expected appearance, check your
- printer preferences.
