# Funciones de bases de datos

Esta seición trata de funciones utilizaes con datos entamaos como una filera de datos pa un rexistru.

La categoría de la Base de Datos pue confundise cola base de datos integrada en LibreOffice. Sicasí, nun esiste conexón ente la base de datos en LibreOffice y la categoría de Base de Datos en LibreOffice Calc.

### Datos d'exemplu:

En dalgunos de los exemplos de descripción de les funciones utilizarán los datos siguientes:

La área A1:Y10 contién los neños convidaos a la fiesta de cumpleaños de Joe. Cada entrada contién la información siguiente: la columna A contién el nome; la columna B, el cursu; de siguío tán la edá n'años, la distancia al colexu en metros y el pesu en kilogramos.

| A | B | C | D | E
1 | Nome | Grau | Edá | Distancia a la escuela | Pesu
2 | Andrés | 3 | 9 | 150 | 40
3 | Bea | 4 | 10 | 1000 | 42
4 | Carlos | 3 | 10 | 300 | 51
5 | Daniel | 5 | 11 | 1200 | 48
6 | Eva | 2 | 8 | 650 | 33
7 | Grau | 2 | 7 | 300 | 42

14 |  |  |  | >600 |
15 |  |  |  |  |
16 | BDCONTAR | 5 |  |  |

La fórmula de la caxella B16 ye =BDCONTAR(A1:Y10;0;A13:Y14)

### Parámetros de les funciones de base de datos:

Los siguientes items son les definiciones de parámetros pa toles funciones de bases de datos.

Database is the cell range defining the database. The first row of the range contains the field names, and following rows are records with corresponding field values.

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 (from the first row of Database range), place quotation marks around the header name.

SearchCriteria is the cell range containing search criteria. Like Database, its first row is also field names, and following rows are conditions for related fields. 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.

See also the Wiki page about Conditional Counting and Summation.

## BDCONTAR

BDCONTAR cunta'l númberu de fileres (rexistros) d'una base de datos que coinciden coles condiciones de busca especificaes y contienen valores numbéricos.

The search supports wildcards or regular expressions. With regular expressions enabled, 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 either precede every character with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in LibreOffice - PreferencesTools - Options - LibreOffice Calc - Calculate.

When using functions where one or more arguments are search criteria strings that represents a regular expression, the first attempt is to convert the string criteria to numbers. For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match. However, when switching to a locale where the decimal separator is not the dot makes the regular expression conversion work. To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as ".[0]" or ".\0" or "(?i).0".

#### Sintaxis

BDCONTAR(Base de datos; Riolo Base de Datos; Busca Avanzada)

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 (from the first row of Database range), place quotation marks around the header name.

If you choose to omit the DatabaseField argument, your formula should be of the form =DCOUNT(Database; ; SearchCriteria).

#### Exemplu

Nel exemplu de riba (muévase escontra riba por favor ), nós queremos saber cuantos neños tienen de viaxar más de 600 metros a la escuela. La resultancia almacenar na caxella B16. Coloque'l cursor na caxella B16. Ingrese la fórmula =BDCONTA(A1:Y10;0;A13:Y14) en B16. El Asistente pa Funciones ayudarálu a ingresar los rangos .

Base de Datos ye'l rangu de datos a ser evaluáu, incluyendo les sos testeres: nesti casu A1:Y10. CampoBasedeDatos especifique la columna pal criteriu de busca. : nésti casu, tola base de datos . CriteriodeBúsqueda ye'l rangu onde pue ingresar los parámetros de busca : nesti casu, A13:Y14.

Pa saber cuántos neños del segundu añu tienen más de 7 años, borre la entrada >600 de la caxella D14 y escriba 2 na caxella B14 debaxo de Nivel; de siguío, escriba 7 na caxella C14 a la drecha. La resultancia ye 2. Dos neños tán en segundu añu y la so edá ye mayor que 7. Como dambos criterios tán na mesma filera, tan coneutaos por un Y.

## BDCONTARA

BDCONTARA cunta'l númberu de fileres (rexistros) d'una base de datos que coinciden coles condiciones de busca especificaes y que contienen valores numbéricos o alfanumbéricos.

The search supports wildcards or regular expressions. With regular expressions enabled, 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 either precede every character with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in LibreOffice - PreferencesTools - Options - LibreOffice Calc - Calculate.

For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match.

To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as ".[0]" or ".\0" or "(?i).0".

#### Sintaxis

DCOUNTA(Base de Datos; Riolo Base de Datos; Busca Avanzada)

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 (from the first row of Database range), place quotation marks around the header name.

If you choose to omit the DatabaseField argument, your formula should be of the form =DCOUNTA(Database; ; SearchCriteria).

#### Exemplu

Nel exemplu enriba (Mueva escontra riba, por favor), usté quier guetar el númberu de neños que'l so nome empieza con Y o una lletra subsecuente. Edite formular en B16 pa lleer =DCOUNTA(A1:Y10;"Name";A13:Y14). Desanicie l'antigua criteriu de busca ya introduza >=Y sol Nome nel campu A14. La resultancia ye 5. Agora, si usté desanicia tolos valores numbéricos pa Greta na filera 8, la resultancia camudara a 4. La filera 8 non sera incluyida na cuenta porque nun contién nengún valor numbéricu. El nome Greta ye testu, non un valor. Nótese que'l Campu Base de Datos tien d'apuntar a dalguna columna que contenga valores numbéricos.

## BDDESVEST
