In Microsoft Access queries have a very significant role, as getting a certain piece of information from a large database is quite impossible without them. In MS Access most of the queries follow particular criteria that are defined at the time of creation. However, sometimes you may need to input different criteria or modify the defined criteria to meet your requirements.

Parameter queries are such flexible queries that prompt user for additional criteria, if required. You can design a parameter query to prompt you for specific piece of information.

Creating queries with different parameters

Creating Parameter queries is all about setting different parameters. You can create queries with one or more parameters. Mentioned below are the steps to create queries with one or more than one parameters:

Creating queries with one parameter

• Start Microsoft Access 2000 and then open the database.

• On the View menu, click Database Objects, and then click Queries.

• In the Database window, click the Purchase-Type query, and then click Design.

• Type the following line in the Criteria cell for the CustomerName field. Note, that the expression that you enter must be enclosed in square brackets.

[View Purchase Type for Customer Name]

• On the Query menu, click Run. When you are prompted, type Jacob, and then click OK to view the results of the query. Note that the query returns only those records whose Customer name is Jacob.

Creating queries with two or more parameters

• Start Microsoft Access 2000 and then open the database

• On the View menu, click Database Objects, and then click Queries.

• In the Database window, click the Purchase-Type query, and then click Design.

• Type the following line in the Criteria cell for the PurchaseDate field.

• Between [Type the beginning date] And [Type the ending date]

• On the Query menu, click Run. When you are prompted for the beginning date, type the beginning data e.g. 1/1/2009, and then click OK. When you are prompted for the ending date, type the ending date e.g. 1/31/2009 and then click OK to view the results of the query. Note that the query returns only records whose purchase date is in January 2009.

This way you can create queries with different parameters and can get the information with desired fields.

Use Kernel for Access Database Repair software if MDB file gets damaged. The software successfully repairs the damaged MDB file and helps you recover the lost data.

The Visual Basic for Applications project in this database is corrupt.

Or

The module name ‘module name’ is misspelled or refers to a module that is invalid.

If the invalid module name is in a macro, an Action Failed dialog box will display the macro name and the macro’s arguments after you click OK. Open the Macro window, and type the correct module name.

If you come across such messages, try to close the database as it might stop responding or start displaying some of the following error messages:

On Microsoft Windows 95 or Microsoft Windows 98:

This program has performed an illegal operation and will be shut down.

If the problem persists, contact the program vendor.

When you click Details on MS Windows Millennium Edition, press Alt+D and you receive the following message:

Furthermore, you also see the error message given below when you try to compact the database:

The Visual Basic for Applications project in this database is corrupt.

Root Cause of the Issue

As the error messages suggests there is probably some corruption issue. It is quite possible that the Visual Basic for Applications project has gone corrupt.

Resolving the Issue

In Access Repair files, data such as forms, reports, and modules utilize Visual Basic for Applications. This implies that corruption of Visual Basic for Applications project might affect forms, reports, and modules in form of corrupting them in-return. For retrieving your tables, queries and macros, follow the steps given below:

1. Create a new blank database.

2. Open the problem database and click Objects > Tables.

3. Right click first table, click Shortcut menu > Export.

4. In Export to dialog box, browse to the database that was initially created.

5. Click the database icon and click OK.

6. Repeat step 4 and 6 for each table, query, and macro.

Usually, the steps given above restore the database. However, in case you fail to restore Access Database

use the qualitative third party MDB repair software to retrieve your lost data. MDB database recovery software is the safest and best way to recover damaged, inaccessible, and corrupt data. The software supports Access 2003, Access 2000, Access 97, and Access 95.

There are two ways using which you can convert data values of Text data type to proper case format.
Use the Built-In String Conversion Function
Use a User-Defined Function
Before going for any one of the above method, first of all create a sample table named MyTestTextList in new blank database MyTestDatabase.
Use the Built-In String Conversion Function
1.Open the MyTestDatabase database in Access.
2.On the Insert menu, click Query. In MS Office Access 2007, click Query Design in the Other group on the Create tab.
3.In the New Query dialog box, click Design view. In Access 2007, skip this step.
4.In the Show Table dialog box, click Close.
5.On the View menu, click SQL View. In Access 2007, click SQL in the Results group on the Design tab.
6.Type the following code in the SQL view:
SELECT testText, STRCONV(testText,3) as TestText_in_Proper_Case FROM MyTestTextList
7.On the Query menu, click Run. In Access 2007, click Run in the Results group on the Design tab.
Use a user-defined function
1.Open the MyTestDatabase database in Access.
2.On the Insert menu, click Module. In Access 2007, click the drop-down arrow under Macro in the Other group on the Create tab.
3.Type the following code in the current module and save your changes.
Function Proper(X)
Capitalize first letter of every word in a field.
Dim Temp$, C$, OldC$, i As Integer
If IsNull(X) Then
Exit Function
Else
Temp$ = CStr(LCase(X))
‘ Initialize OldC$ to a single space because first>
‘ letter must be capitalized but has no preceding letter.
OldC$ = ” ”
For i = 1 To Len(Temp$)
C$ = Mid$(Temp$, i, 1)
If C$ >= “a” And C$ <= “z” And (OldC$ < “a” Or OldC$ > “z”) Then
Mid$(Temp$, i, 1) = UCase$(C$)
End If
OldC$ = C$
Next i
Proper = Temp$
End If
End Function
4.On the File menu, click Close and Return to Microsoft Access.
5.On the Insert menu, click Query. In Access 2007, click Query Design in the Other group on the Create tab.
6.In the New Query dialog box, click Design view. In Access 2007, skip this step.
7.In the Show Table dialog box, click Close.
8.On the View menu, click SQL View. In Access 2007, click SQL in the Results group on the Design tab.
9.Type the following code in the SQL view:
10.SELECT testText, proper(testText) as testText_in_Proper_Case FROM MyTestTextList
11.This query is similar to the query in Method 1. This is except for the function call.
12.On the Query menu, click Run. In Access 2007, click Run in the Results group on the Design tab
Second method gives you the flexibility to select any case format. This way you are able to convert data values of Text data type to proper case format in MS Access.
