The basic building block of a macro; a self- contained instruction that can be combined with other actions to automate tasks. This is sometimes called a command in other macro languages. Additional information required by some macro actions. For example, the object affected by the action or special conditions under which the action is carried out. The list that appears when you click the arrow in the Action column of the Macro object tab.

A query that copies or changes data. Action queries include append, delete, make- table, and update queries. They are identified by an exclamation point (!) next to their names in the Navigation Pane. A row in the upper part of the Macro object tab in which you enter macro names, actions, arguments, and comments associated with a particular macro or macro group. ADE file An Access project (.

Advanced Filter/Sort window A window in which you can create a filter from scratch. You enter criteria expressions in the filter design grid to restrict the records in the open form or datasheet to a subset of records that meet the criteria. A function, such as Sum, Count, Avg, or Var, that you use to calculate totals. In an Access database (.

The anonymous replica is particularly useful in an Internet situation where you expect many users to download replicas. ANSI SQL query mode One of two types of SQL syntax: ANSI- 8. SQL (also called Microsoft Jet SQL and ANSI SQL), which is the traditional Jet SQL syntax; and ANSI- 9. SQL, which has new and different reserved words, syntax rules, and wildcard characters. An action query that adds the records in a query's result set to the end of an existing table.

The background area of an application window. ASCII American Standard Code for Information Interchange (ASCII) 7- bit character set used to represent letters and symbols found on a standard U. S. Three kinds of numbers can be generated: sequential, random, and Replication ID. A table in an Access database. You can manipulate the structure of a base table by using the DAO objects or data definition (DDL) SQL statements, and you can modify data in a base table by using Recordset objects or action queries.

In an Access project, a data type of 8 bytes (6. In an Access project, a fixed- length data type with a maximum of 8,0. In an Access project, a data type that stores either a 1 or 0 value. Integer values other than 1 or 0 are accepted, but they are always interpreted as 1. A value that is used with bitwise operators (And, Eqv, Imp, Not, Or, and Xor) to test, set, or reset the state of individual bits in a bitwise field value. A bit- by- bit comparison between identically positioned bits in two numeric expressions.

Bookmark A property of a Recordset object or a form that contains a binary string identifying the current record. The column in a list box, combo box, or drop- down list box that is bound to the field specified by the control's Control.

Working with the data in Microsoft Access tables is very important and is often difficult for new users to understand how to properly design tables to store data in. You can create a single PRIMARY KEY constraint as part of the table definition when a table is created. If a table already exists, you can add PRIMARY KEY constraint. VBA code using DDL statements (Data Definition Language - part of SQL) in Microsoft Access. Microsoft SQL Server is a SQL-based relational database management system designed for use in corporate applications, both on premises and in the cloud. 1 From the 13 primary data types listed in SQL Data Types. Examining Data Types. Both the DAO object model and the ADOX object model provide ways of examining. This definition details the origins of Microsoft; its notable products, such as the Windows operating system; and a history of the company's leadership.

Have you ever wondered what is Microsoft Access, if the answer is Yes, then this would be a good place to start. Returns information about all the waits encountered by threads that executed. You can use this aggregated view to diagnose performance issues with SQL Server and also. Also see RAM types. SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dyna.

Source property. bound control A control used on a form, report, or data access page to display or modify data from a table, query, or SQL statement. The control's Control.

Source property stores the field name to which the control is bound. A control that is used on a data access page to bind a link, an intranet address, or an Internet address to an underlying Text field. You can click the hyperlink to go to the target location. A control on a form or report that is used to display and manipulate OLE objects that are stored in tables. Installation Guide For Oracle 10G Support more.

A control that is used on a form, report, or data access page to bind an image to an OLE Object field in an Access database or an image column in an Access project. A control that is used on a data access page to bind HTML code to a Text or Memo field in an Access database or to a text, ntext, or varchar column in an Access project. You cannot edit the contents of a bound span control. An Access tool that simplifies a task. For example, you can quickly create a complex expression by using the Expression Builder.

In Access 2. 00. 3 and earlier, a toolbar that is part of the Access user interface when it is installed on your computer. In contrast, a custom toolbar is one that you create for your own database application.

In Access 2. 00. 7, toolbars are replaced by the Ribbon, which arranges commands in related groups on tabs. In addition, you can add commands that you frequently use to the Quick Access Toolbar. Byte data type An Access database data type that is used to hold small positive integers ranging from 0 to 2.

A control that is used on a form, report, or data access page to display the result of an expression. The result is recalculated each time there is a change in any of the values on which the expression is based. A field, defined in a query, that displays the result of an expression rather than displaying stored data.

The value is recalculated each time a value in the expression changes. All modules that might be called by any procedure in the module in which code is currently running. The section on a grouped data access page that displays captions for columns of data. It appears immediately before the group header. You cannot add a bound control to a caption section.

Cartesian product The result of executing an SQL SELECT statement that includes two or more tables in the FROM clause, but no WHERE or JOIN clause that indicates how the tables are to be joined. The process of one action triggering another action. For example, when a cascading update relationship is defined for two or more tables, an update to the primary key in the primary table automatically triggers changes to the foreign table. For relationships that enforce referential integrity between tables, the deletion of all related records in the related table or tables when a record in the primary table is deleted. A sequence of events caused by an event procedure directly or indirectly calling itself; also called an event cascade or a recursion.

Be careful using cascading events, because they often result in stack- overflow or other run- time errors. For relationships that enforce referential integrity between tables, the updating of all related records in the related table or tables when a record in the primary table is changed. A field that is displayed in the category area of Pivot. Chart view. Items in a category field appear as labels on the category axis.

An integer that corresponds to an open Dynamic Data Exchange (DDE) channel. Channel numbers are assigned by Microsoft Windows 9. DDEInitiate function, and used by other DDE functions and statements. In an Access project, a fixed- length data type with a maximum of 8,0. ANSI characters. character code A number that represents a particular character in a set, such as the ANSI character set.

A graphical representation of data in a form, report, or data access page. A control that indicates whether an option is selected. A check mark appears in the box when the option is selected.

CHECK constraint Allows for business rules that span multiple tables. For example, the Order table could have a CHECK constraint that would prevent orders for a customer from exceeding a credit limit defined for the customer in the Customer table. A module that can contain the definition for a new object. Each instance of a class creates a new object. Procedures defined in the module become properties and methods of the object. Class modules can exist alone or with forms and reports.

The name used to refer to a class module. If the class module is a form or report module, the class name is prefaced with the type of module — for example, Form.
