The LIKE condition allows you to use wildcards in the where clause of a SQL statement in Access 2007. This allows you to perform pattern matching. This allows you to perform pattern matching. The LIKE condition can be used in any valid SQL statement - select, insert, update, or delete. Access Functions (by category) This article contains links to articles that provide details about common functions used in expressions in Microsoft Access. They are arranged first by group and then are arranged alphabetically at the end of this article. Tip: Beginning with Access 2010, the Expression Builder has IntelliSense. GetTimeCardTotal sample function To create the GetTimeCardTotal function, follow these steps: NOTE: The sample code in this article uses Microsoft Data Access Objects.

Compares a string against a pattern.
Important
The
Like operator is currently not supported in .NET Core and .NET Standard projects.
SyntaxPartsresult Required. Any Boolean variable. The result is a Boolean value indicating whether or not the string satisfies the pattern .
string Required. Any String expression.
pattern Required. Any String expression conforming to the pattern-matching conventions described in 'Remarks.'
Remarks
If the value in
string satisfies the pattern contained in pattern , result is True . If the string does not satisfy the pattern, result is False . If both string and pattern are empty strings, the result is True .
Comparison Method
The behavior of the
Like operator depends on the Option Compare Statement. The default string comparison method for each source file is Option Compare Binary .
Pattern Options
Built-in pattern matching provides a versatile tool for string comparisons. The pattern-matching features allow you to match each character in
string against a specific character, a wildcard character, a character list, or a character range. The following table shows the characters allowed in pattern and what they match.
Character Lists
A group of one or more characters (
charlist ) enclosed in brackets ([ ] ) can be used to match any single character in string and can include almost any character code, including digits.
An exclamation point (
! ) at the beginning of charlist means that a match is made if any character except the characters in charlist is found in string . When used outside brackets, the exclamation point matches itself.
Special Characters
To match the special characters left bracket (
[ ), question mark (? ), number sign (# ), and asterisk (* ), enclose them in brackets. The right bracket (] ) cannot be used within a group to match itself, but it can be used outside a group as an individual character.
The character sequence
[] is considered a zero-length string (' ). However, it cannot be part of a character list enclosed in brackets. If you want to check whether a position in string contains one of a group of characters or no character at all, you can use Like twice. For an example, see How to: Match a String against a Pattern.
Character Ranges
By using a hyphen (
– ) to separate the lower and upper bounds of the range, charlist can specify a range of characters. For example, [A–Z] results in a match if the corresponding character position in string contains any character within the range A –Z , and [!H–L] results in a match if the corresponding character position contains any character outside the range H –L .
When you specify a range of characters, they must appear in ascending sort order, that is, from lowest to highest. Thus,
[A–Z] is a valid pattern, but [Z–A] is not.
Multiple Character Ranges
To specify multiple ranges for the same character position, put them within the same brackets without delimiters. For example,
[A–CX–Z] results in a match if the corresponding character position in string contains any character within either the range A –C or the range X –Z .
![]() Usage of the Hyphen
A hyphen (
– ) can appear either at the beginning (after an exclamation point, if any) or at the end of charlist to match itself. In any other location, the hyphen identifies a range of characters delimited by the characters on either side of the hyphen.
Collating Sequence
The meaning of a specified range depends on the character ordering at run time, as determined by
Option Compare and the locale setting of the system the code is running on. With Option Compare Binary , the range [A–E] matches A , B , C , D , and E . With Option Compare Text , [A–E] matches A , a , À , à , B , b , C , c , D , d , E , and e . The range does not match Ê or ê because accented characters collate after unaccented characters in the sort order.
Digraph Characters
In some languages, there are alphabetic characters that represent two separate characters. For example, several languages use the character
æ to represent the characters a and e when they appear together. The Like operator recognizes that the single digraph character and the two individual characters are equivalent.
When a language that uses a digraph character is specified in the system locale settings, an occurrence of the single digraph character in either
pattern or string matches the equivalent two-character sequence in the other string. Similarly, a digraph character in pattern enclosed in brackets (by itself, in a list, or in a range) matches the equivalent two-character sequence in string .
Overloading
The
Like operator can be overloaded, which means that a class or structure can redefine its behavior when an operand has the type of that class or structure. If your code uses this operator on such a class or structure, be sure you understand its redefined behavior. For more information, see Operator Procedures.
ExampleAccess Query With Like
This example uses the
Like operator to compare strings to various patterns. The results go into a Boolean variable indicating whether each string satisfies the pattern.

Microsoft Access is the simple way to create a database to store and manage data. It is extremely flexible. Microsoft access is a convenient way to enter the data and does not take much time. There is a wide range of simple and enterprise applications available on access database. At first the user may find it a little complex to operate. As the access will be used, it becomes easier for the user to explore the powerful features of Microsoft Access. Microsoft access has gained more importance with the release of Access 2016.
Basic Things about Microsoft Access
The more you use Access the better you can explore the new features of Microsoft Access that can make the job simpler. Once you start using the Microsoft access, you will realize how it has become one of the necessities in today’s time. Access is available in Microsoft Office suite. Microsoft access is one excellent tool that has a huge database. With this tool, you can organize the data as per your convenience. Microsoft access is a cost friendly option that saves ample of time in creating a database. There are some amazing features features of Microsoft Access that can transform a regular database into a user-friendly application.
Excel functions, formula, charts, formatting creating excel dashboard & others
The New features of Microsoft Access
There are many new features of Microsoft Access that have been added in access which makes it more user-friendly. With a regular access database, you can integrate the apps like mom & pop inventory tracker. The new features of Microsoft Access has the ability to create the database for web and publish the same. Other than this, image gallery, browser control and certain developer enhancements have also been added. If you take a look at access, there is a new feature called Ribbon interface. It gives better accessibility to menu options and commands.
Advantages of Microsoft Access
As said earlier, access is the best tool for database. Microsoft access can help you make the quick changes in the first place. The changes and additions can easily be added without hampering other data. Access 2016 is a perfect solution for small scale business. Microsoft access can improve your system without letting you empty your pockets or long time delays. Access has a VBA language which is used by developers and programmers the most. This means you can make the changes in already ready database simply with the help of the source files.
Uses of Microsoft Access:
Microsoft Access is one efficient platform for the individual or the small business who want to report and manage the data in a professional manner. If you use it with relational Microsoft Jet Database Engine, you get an efficient software-development tool for better management. People can create an effective database that too in an advanced manner as Microsoft Access does not have any complicated programming being used. With this relational database application tool, user can efficiently use the data whenever required at minimal effort.
Features of Microsoft Access wizards and design options to create a table professionally. The data which are saved in MS-Access can also be exported easily in the spreadsheets. This makes the job of further analysis simpler. You can easily amalgamate Access with word and excel. Whatever data gets stored in Microsoft Access can be used in any MS-Office applications. Suppose you add a data of name and address of an individual in Microsoft Access which you an import and use in MS-word easily.
You don’t really have to depend on the person who created the data. Once it gets stored, you can easily edit and add the changes without any kind of hassle. Being an effective data base tool, it offers the user a friendly experience. Any work related to data such as data retrieval, data input, data edit can be effectively done with MS-Access. Options like Edit, File makes it convenient for the user to manage a good database.

Query is another great feature that gives user a customized view of the data. Access has the facility of the graphical query by example. It means any SQL statement can be written easily for creating the queries. You also have the right to insert, select, delete and update the data by defining the queries. There is also a facility to define the query for creating new tables from data in existing tables. Query is a request made by the user to understand the results of the data.
There are different uses of query. Generally it is used to derive the answer for simple issues, make calculation and combine the data with any other table. Some people also uses query to make the changes, add, or delete the data of the table. It assembles the data that you want to use before you move on too deigns the form or report.
Events are related to Visual Basic process or Macros. To define it in simpler terms it a change in the Access object state. To open a form, enter a new form, or close an existing form, the use of event is made while writing macros. The process of event is also known as triggers, flags, and indicators. Events generally flow one after another. Before you use it in your course of action ensure that you are clear with this concept very well.
There is a process of event which offers visual basic programming tutorials. The page states detailed information of the event process along with some programming examples. In events the use of syntax is commonly made during certain source code. When the object initiates an action, it comes in form of an event. The action is usually simple such as placing the mouse on the object without the need to click. This action may also consist of right click, left click and rolling the wheel.
There is no hard and fast rule to add up the datasheet total. You can add the total number of rows to the fields present in the database. The summery that is received will first filter the list and shows the data that a user is expecting. On the Records ribbon you have to click at the total Item. This will give you a total row for the datasheet where you can put the summery type for every column.
This is another mind blowing feature that has been added in the Microsoft Access. It has a set definition of one or more actions that are required in access for defining an event. For example, if you select an item on the main form, you can also design a macro that would open a second form. You get an option to create another macro for validating the field content and make the necessary changes. Macros are also used for opening and executing the queries and viewing the reports.

There are times when a user might want to resize a form which has been designed by another user during a run time. For better resizing and reposition, you can use the Anchoring feature. You simply have to position the anchor properly so that the size positioning can be controlled. Once the control is maintained, the distance between the anchor position and control also gets automatically set. The control can be positioned vertically as well so that its location remains the same from the edge of the form.
Anchoring is one cool feature which gives your form a professional look. It is easy to expand and fit it to the size of from horizontally and vertically with one click. The only fact is it does not support the font sizes that are adjusting. If you don’t prefer coding then this option is the best.

This is another popular features of Microsoft Access that has visual basic. It offers a better action flow and eradicates the errors which you may not easily remove with macros. This object has a custom process that is similar to the codes used for visual basic. Module has a standalone object which can be called from anywhere for your application. It is extremely easy to use. They are associated with a report as a response given on certain event
A module is the combination of data that includes stamen, declaration and process which are together stored as a unit. Macros and module perform almost same action but there are certain changes in the results. Both these features of Microsoft Access add a great functionality to the database. To write module VBA (Visual Basic for Applications) programming language is used.
There are two types of module: Standard modules and class module. Class module is the process in which the focus is made only on certain form. Standard module is a general process which is not restricted to a certain form. It is listed under Navigation Pane unlike class module.
Like Function In Access
User might have faced certain drawbacks with the database container elimination. The good news is Search Bar feature makes up for it. This feature is located on the navigation pane. The users were trained to search for an item in a grid or through the location from navigation pane directly. This was quite frustrating. The good news is, a new update in the access with regards to search bar has altogether a different approach. Simply enter the letter of the file name and you get the result. This feature was not present in older versions of access.
This features of Microsoft Access is available on a form that has a data. In control, you can design Visual Basic procedure or Macros. When the individual keys are pressed by the user, control responds to it while entering the data. Controls are used for entering, editing or displaying the data in the form. A text box is a perfect example of the control that displays the data on report. Other examples are check boxes, command button and combo boxes to name a few.
There are three categories of control namely calculated, bound, and unbound. With control you can see and work on the data that is present in the application of database. In bound control, a data is considered as a table field. Unbound control does not have any kind of data source. Calculated control has a data source with expression. This is considered as an important feature of Microsoft access which is commonly used.
These are the complex field types that are commonly used in Access 2007. With multivalued fields it becomes easy to support the instances or values that you want to store without the need of advanced database design. Such type of field is used for integrating with SharePoint service. Suppose there are many employees who are working for the same project. With such feature, you can store all their names in a single field. It makes the job of database developer to create and design the tables.
Attachment field is another great features of Microsoft Access in which you can add more than one pieces of data together and record it in the database. It becomes easy for you to store different files in a single field. Suppose you have a contacts database job. This feature gives you a privilege to attach more than one resume for the record purpose. It has a better efficiency to store data. With attachment field, you can pen the document and other files that don’t have images. This makes it easy for the user to search and edit the files.
With so many amazing features of Microsoft Access, there is no doubt on why Microsoft Access is one of the leading database systems. There are millions of users and developers who choose it as a convenient platform to create an effective data. For medium and small scale business this type of tool is a life saver. To make the right use of it, explore more features of Microsoft Access and know where to apply them for the better results. So far the users who have chosen it for making an effective database have given positive feedback about it.
