Microsoft Access 2010 - Lesson 21: Database Conditional Values
Here is the difference (it is important to understand this because it is used in many other environments, including Microsoft Visual Basic and Microsoft SQL Server): Imagine a field is used for a first name and the field displays Paul. the Field Templates, from the Basic Fields section, drag Checkbox and drop it on the right side of Stories On the table, double-click the newly added Checkbox column header and type Has Finished Basement? Right-click the Properties tab and click Design View In the top section of the table, right-click Year Built and click Insert Rows Type With Indoor Garage Press Tab and type y Save and close the table Options of Boolean Fields Microsoft Access provides different options to support various ways of expressing a Boolean field: If you are working in the Datasheet View, click a cell in the Boolean column you want to configure
VBA DCount() with variable field name Microsoft Access
The correct way to deal with nullable fields on DB2 was to use that second variable, do the null check BEFORE attempting to access the variable which is suppose to contain the value of said field
Microsoft Access VBA - Lesson 26: ADO and Record Sets
To specify the type of cursor you want to use, you can pass a member of the CursorTypeEnum enumeration as the third argument of the Recordset.Open method. If the database is small enough, which is the case for a restricted environment, the likelihood of two people editing or updating the same record (at the same time) may be low
Microsoft Access tips: VBA Function index
Where are macros used in forms or reports? UsePrinter() Assign the Printer object (Access 2002 and later.) Printer Selection Utility UserCount() Count the number of distinct users connected to the database. Problem properties FolderExists() Determine whether a folder exists Determine if a file or folder exists ForceClosed() Close a form or report, even if it means losing the edit in progress
If you have a database where comments are entered frequently by data entry personnel, one of the first features they will ask for will be spell checking
If there are records returned, the recordcount will always be 1 or more, and when none are returned, it will always be zero, no matter whether you .MoveLast or not. Certainly, (If rs.EOF) will not accurately indicate an empty recordset if you do something to move the cursor - but the point is, that at *opening* of a recordset, (If rs.EOF) will accurately indicate if there are no records
One tests for a value (empty strings are values) andthe other sees what of two values is logically greater.An empty string is less than a 'normal' string and a numeric variablewith no value defaults to 0.However when doing this and one of the values is Null (mainly whenusing variants) the comparison will always fail because a null has novalue to test.I find the easiest test when you need to know if something is null isto use the Nz function
VBA to check if recordset is empty? Microsoft Access
I can return the recordset if I do not close either the recordset or connection but know this to be bad practice as well as causing the MDB file to bloat. I need to write a code in vba (actually a module) to sequentially browse through different columns in the table and check whether the columns are empty or not
