Some days after that post, I received some e-mail requests about doing the same, but for Access databases. Criteria and field selections can be from any of the query's tables.
Forthcoming tutorials in this series will show how this can be done. What you will see here is the way I like to write my code. Count - 1 Sheets "New Query". Join Properties dialog box. Sheets "Existing Access Query". A simple two table query calculates these results even when the size of the numeric ranges are not identical.
Most SQL errors are syntax errors. In our example, the Age data are integers so using integers in this table is okay. If Access automatically creates the correct joins when you add the data sources, you can skip ahead to Step 3: Examples are shown later.
There are several ways to join tables in a query. You use criteria to limit the records that your query returns, on the basis of whether field values meet the criteria that you specify. These errors are usually quite easy to trace: Add any criteria to the fields that you want.

If your destination table contains a primary key, make sure you append unique, non-Null values to the primary key field or fields; if you do not, the Microsoft Access database engine will not append the records.
In some places I have provided separate instructions for Access A thorough explanation of expressions is beyond the scope of this article. The solution some like is to use to always use either single quotes or double quotes for delimiters. Drag the fields from a data source in the upper pane of the query design window down to the Field row of the design grid, in the bottom pane of the query design window.
You can also make use of your custom functions in any VBA procedures you write. Of course, you need to be careful modifying the "core" queries. A thorough explanation of expressions is beyond the scope of this article. Pressing the Debug button will take you to the offending line of code but this may not be the SQL statement itself.
I usually use the abbreviation "DoB" when referring to date of birth. SQL Error Messages It pays to familiarise yourself with the different sorts of message so that you can quickly trace the source of code errors. You can choose whether or not to display this field.Running Access Queries From Excel Using VBA (Josh and Maria) asked me to write two different VBA codes for running Access queries directly from Excel.
I decided to “answer” to both requests by writing this post since both of them are related to the same subject: Access queries. For example, when you type text in an expression for a validation rule or for query criteria, Access surrounds your text strings with quotation marks automatically.
For example, if you type the text Paris, Access displays "Paris" in the expression. Constructing an SQL statement in VBA can be tricky, because there are often several areas of Access needed to construct the string. For example, proper SQL syntax, proper VBA syntax, and proper referencing of controls are three common points.
The Access query design window accepts dates in your local default format but it converts the date you type to the correct format when it builds the SQL statement. Remember the Semicolon! An SQL statement must finish with a semicolon (;). Constructing an SQL statement in VBA can be tricky, because there are often several areas of Access needed to construct the string.
For example, proper SQL syntax, proper VBA syntax, and proper referencing of controls are three common points. @Remou please more info on palmolive2day.comry, i don't want to use SQL, I have the Query already done in ms-access – Smith Dec 31 '10 at oops Openquery: palmolive2day.com(v=office).aspx.Download
