![]() ![]() A report organizes the information from the fields of a query or table into a document according to your requirements. A query creates a new table from the existing tables based upon how you create the query. They can also be used for viewing fields from one or more tables associated with the form. Forms are for data entry into the fields of one or more tables which have been associated with the form. When creating a table, you also determine the characteristics of each field within it. Each table of the database is a group of fields. LibreOffice uses the terms “Data Source” and “Database” to refer to the same thing, which could be a database such as MySQL or dBase, a spreadsheet or text document holding data, or an address book.Ī database consists of a number of fields that contain the individual pieces of data. This chapter covers creating a database, showing what is contained in a database, and how the different parts are used by LibreOffice. It can create and store an embedded database or connect to external databases. A business stock list could be a data source managed through LibreOffice.īase is the database front-end component of LibreOffice. For example, a list of names and addresses is a data source that could be used for producing a mail merge letter. ⌥ (Option) or Alt, depending on keyboardĪ data source, or database, is a collection of pieces of information that can be accessed or managed by LibreOffice. For a detailed list, see the application Help.Ĭontrol+click or right-click depending on computer setup The table below gives some common substitutions for the instructions in this document. Some keystrokes and menu items are different on macOS from those used in Windows and Linux. Other versions of LibreOffice may differ in appearance and functionality.

It converts a string into a number however it always expects a period to be used as the decimal point symbol.This document is Copyright © 2022 by the LibreOffice Documentation Team. The Val function is different from the Csng, Cdbl and Cstr methods. Conversely, the CStr methods use the currently selected country-specific settings when formatting numbers, dates and time details. The symbol defined in the corresponding country-specific settings must be used as the decimal point symbol. The numerical CSng and CDbl conversion functions also accept decimal numbers. In the second instance, the integer variables are first converted into two strings and then linked with one another by means of the assignment. You can use these conversion functions to define how Apache OpenOffice Basic should perform these type conversion operations:ĭim A As String Dim B As Integer Dim C As IntegerĪ = CStr (B + C ) ' B and C are added together first, then ' converted to the string "2"Ī = CStr (B ) + CStr (C ) ' B and C are converted into a string,then ' combined to produce the string "11"ĭuring the first addition in the example, Apache OpenOffice Basic first adds the integer variables and then converts the result into a chain of characters. To avoid other errors resulting from implicit type conversions, Apache OpenOffice Basic offers a range of conversion functions, which you can use to define when the datatype of an operation should be converted:ĬStr(Var) converts any data type into a string.ĬInt(Var) converts any data types into an integer value.ĬLng(Var) converts any data types into a long value.ĬSng(Var) converts any data types into a single value.ĬDbl(Var) converts any data types into a double value.ĬBool(Var) converts any data types into a Boolean value.ĬDate(Var) converts any data types into a date value. The error sources noted for implicit type conversions can only be avoided by careful programming for example, by not using the variant datatype. ![]() Since variant variables may contain both numbers and strings, it is unclear whether variable A is assigned the number 2 or the string 11. ![]()
