# Funkcije baze podataka

This section deals with functions used with data organized as one row of data for one record.

The Database category may be confused with a database integrated in LibreOffice. However, there is no connection between a database in LibreOffice and the Database category in LibreOffice Calc.

### Example Data:

The following data will be used in some of the function description examples:

The range A1:E10 lists the children invited to Joe's birthday party. The following information is given for each entry: column A shows the name, B the grade, then age in years, distance to school in meters and weight in kilograms.

| A | B | C | D | E
1 | -3,48 | -10000 | -3,48 | Distance to School | Primljeno
2 | -3,48 | 3 | 9 | 150 | 40
3 | -10000 | 4 | 10 | 1000 | 42
4 | Primljeno | 3 | 10 | 300 | 51
5 | deponirani | 5 | 11 | 1200 | 48
6 | -3,48 | 2 | 8 | 650 | 33
7 | -10000 | 2 | 7 | 300 | 42
8 | -10000 | 1 | 7 | 200 | 36
9 | -10000 | 3 | 9 | 1200 | 44
10 | Primljeno | 2 | 8 | 1000 | 42
11 |  |  |  |  |
12 |  |  |  |  |
13 | -3,48 | -10000 | -3,48 | Distance to School | Primljeno
14 |  |  |  | >600 |
15 |  |  |  |  |
16 | -3,48 | 5 |  |  |

The formula in cell B16 is =DCOUNT(A1:E10;D1;A13:E14)

### Database Function Parameters:

The following items are the parameter definitions for all database functions:

Database is the cell range defining the database.

DatabaseField specifies the column where the function operates on after the search criteria of the first parameter is applied and the data rows are selected. It is not related to the search criteria itself. For the DatabaseField parameter you can enter a reference to a header cell or a number to specify the column within the Database area, starting with 1. To reference a column by means of the literal column header name, place quotation marks around the header name.

SearchCriteria is the cell range containing search criteria. If you write several criteria in one row they are connected by AND. If you write the criteria in different rows they are connected by OR. Empty cells in the search criteria range will be ignored.

Choose LibreOffice - PreferencesTools - Options
- LibreOffice Calc - Calculate to define how LibreOffice Calc acts when searching for identical entries.

## DAVERAGE

DAVERAGE vraca prosjeke vrijednosti svih celija (polja) u svim redovima (slogovi baze podataka) koji odgovaraju specificiranom kriteriju pretrage.

The search supports regular expressions. You can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must precede every character with a \ character. You can switch the automatic evaluation of regular expression on and off in LibreOffice - PreferencesTools - Options
- LibreOffice Calc - Calculate.

### Sintaksa

DAVERAGE(Database; Database_field; Search_criteria)

For the DatabaseField parameter you can enter a reference to a header cell or a number to specify the column within the Database area, starting with 1. To reference a column by means of the literal column header name, place quotation marks around the header name.

### Primjer

Da bi pronašli prosjecnu težinu sve djece istih godina u primjeru gore (pomjerite gore), unesite slijedecu formulu u B16:

=DAVERAGE(A1:E10; "Weight"; A13:E14)

U red 14, pod Age (Godine), unesite 7, 8, 9, itd, jedno za drugim. Pojavi se prosjecna težina sve djece iste starosti.

## DCOUNT

DCOUNTA racuna broj redova (slogova) u bazi podataka koji se slaže sa specificiranim uslovima pretrage i sadrži numercke ili alfanumericke vrijednosti.

The search supports regular expressions. You can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must precede every character with a \ character. You can switch the automatic evaluation of regular expression on and off in LibreOffice - PreferencesTools - Options
- LibreOffice Calc - Calculate.

### Sintaksa

DCOUNT(Database; Database_field; Search_criteria)

If the DatabaseField argument is omitted, DCOUNT returns the count of all records that satisfy Criteria. For the DatabaseField parameter you can enter a reference to a header cell or a number to specify the column within the Database area, starting with 1. To reference a column by means of the literal column header name, place quotation marks around the header name.

### Primjer

U primjeru gore (pomjerite gore), Želimo znati koliko djece mora da putuje duže od 600 metara do škole. Rezultat ce se pohraniti u celiju B16. Postavite kursor na celiju B16. Unesite formulu =DCOUNT(A1:E10; 0; A13:E14) u B16. Čarobnjak za funkcije vam pomaže da unesete raspon.

Baza podataka je raspon podataka za procjenu, ukljucujuci zaglavlja: u ovom slucaju A1:E10. Database_field odreduje kolonu za kriterij pretrage: u ovom slucaju, cijela baza podataka. Search_criteria je raspon u kojem možete unijeti parametre za pretragu: u ovom slucaju, A13:E14.

Da bi saznali koliko djece u drugom razredu ima više od 7 godina, izbrišite unos >600 u celiji D14 i unesite 2 u celiju B14 pod Grade i unesite >7 u celiju C14 na desno. Rezultat je 2. Dvoje djece starije od 7 je u drugom razredu. Kako su oba kriterija u istom redu, povezani su sa AND.

## DCOUNTA

DCOUNTA racuna broj redova (slogova) u bazi podataka koji se slaže sa specificiranim uslovima pretrage i sadrži numercke ili alfanumericke vrijednosti.

The search supports regular expressions. You can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must precede every character with a \ character. You can switch the automatic evaluation of regular expression on and off in LibreOffice - PreferencesTools - Options
- LibreOffice Calc - Calculate.

### Sintaksa

DCOUNTA(Database; Database_field; Search_criteria)

If the DatabaseField argument is omitted, DCOUNTA returns the count of all records that satisfy Criteria. For the DatabaseField parameter you can enter a reference to a header cell or a number to specify the column within the Database area, starting with 1. To reference a column by means of the literal column header name, place quotation marks around the header name.

### Primjer

U primjeru gore (pomjerite gore), možete tražiti broj djece cija imena pocinju sa E ili narednim slovom. Uredite formulu u B16 da bi procitali =DCOUNTA(A1:E10; "Age"; A13:E14). Obrišite stari kriterij pretrage i unesite >=E pod Name (Ime) u polje A14. Rezultat je 5. Ako sada izbrišete sve numericke vrijednosti za Greta u redu 8, rezultat se mijenja na 4. Row 8 is no longer includRed 8 više nije ukljucen u racunanje jer ne sadrži nikakve vrijednosti. Ime Greta je tekst a ne vrijednost. Primjetite da Database_field parametar mora ukazati na kolonu koja sadrži vrijednosti.

## DGET

DGET vraca sadržaje referirane celije u bazi podataka koji odgovara specificiranom kriteriju pretrage. U slucaju greške, funkcija vraca ili #VALUE! za novu nadenu vrijednost ili Err502 za nadenih vide celija.

The search supports regular expressions. You can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must precede every character with a \ character. You can switch the automatic evaluation of regular expression on and off in LibreOffice - PreferencesTools - Options
- LibreOffice Calc - Calculate.

### Sintaksa

DGET(Database; Database_field; Search_criteria)

For the DatabaseField parameter you can enter a reference to a header cell or a number to specify the column within the Database area, starting with 1. To reference a column by means of the literal column header name, place quotation marks around the header name.

### Primjer

U primjeru gore (pomjerite gore), Želimo odrediti koji je razred dijete cije je ima unešeno u celiju A14. Formula je unešena u celiju B16 i malo se razlikuje od ranijih primjera jer samo jedna kolona (jedno polje baze podataka) može unijeti za Database_field. Unesite slijedecu formulu:

=DGET(A1:E10; "Grade"; A13:E14)

Unesite ime Frank u A14 i vidjecete rezultat 2. Frank je u drugom razredu. Unesite "Age" umjesto "Grade" i dobicete Frankove godine.

Ili unesite vrijednost 11 samo u celiju C14 i izbrišite ostale unose u ovom redu. Uredite formulu u B16 kako slijedi:

=DGET(A1:E10; "Name"; A13:E14)

Umjesto razreda, traženo je ime. Odgovor se odmah pojavi: Daniel je jedino dijete koje ima 11 godina.
