By using data already in the cache it reduces load on the database, the network, and the BI Server. Should you be using it? If the foundations are not not in place?

Different developers have their own ways of doing things and this is reflected in their coding style.

Access Tips: Access and SQL Part 2: Putting VBA and SQL Together

What you will see here is the way I like to write my code. SQL statements can also be quite long, and for that reason they are usually assigned to text variables so that they are easier to handle.

Access doesn't care if you do this or not but you will find your code much easier to read and understand if you do. Compare these two statements: Lastname from tblStaff where tblStaff. Access only demands that you do this when your field names contain spaces.

The brackets tell Access that all the words in the field name belong together. They also tell Access that "this is a field name" and so allows you to use otherwise reserved words for the names of fields such as [Date] which is also the name of a function without causing conflicts.

But I do this for another reason too. I know that if I see some text in square brackets I know it's a field name, whether it has spaces in it or not This makes long statements much easier to read and edit Don't forget that each line must have both opening and closing quotes.

The statement itself needs to be enclosed in quotes because it is a VBA text string. If you use the same type of quote mark for each Access will get confused. Look at this example Compare the two examples below.

In the first example the VBA sees two text strings enclosed by double quote marks, and between them a word it doesn't know Paris so it generates an error. But when the quote marks are alternated as shown in the second example, the problem doesn't arise.

The VBA sees a text string enclosed by double quotes, inside which is some more text enclosed in single quotes.

I working with multiple sets of quotes gets confusing, you can always use the ASCII character code for the double quote mark - Chr 34 - instead. There is an example of this in the next section.

Putting It All Together Some of these rules are essential, others are just my way of doing things and that of many other database developers. The illustration below shows a completed SQL statement written the way I suggest [click the thumbnail to see a full-sized image]: But this won't often be the case.

You might be changing the criteria, fields or even data sources specified in your SQL statements each time the code is run. The information that the SQL statement needs is often obtained from the user through their choices in a dialog box or from the values in fields on a form.

Forthcoming tutorials in this series will show how this can be done. You want to allow the user to choose a value for the Office criteria each time the query is run, so you build a dialog box in which there is a combo box containing a list of Offices.

The combo box is named cboOffice. You can insert a reference to the value of the combo box directly into the SQL statement: Alternatively, you can place the value of the combo box into a variable and then insert the variable into the SQL statement: Using a variable can make the SQL statement code easier to read and understand, especially when there are several variable criteria to consider.

Need to write a SQL query to search special character in a column. Text needed to search is 'R&D' but issue is that SQL server is taking it as a logical operator. This is correct and it will work, but the query is modified to work around an obstacle raised by the front-end program (like SQL*Plus). The better solution, as Bob Jarvis has shown in his answer, is to tell the front-end to behave nicely - by turning off that feature in the front-end itself.

It is sometimes essential to use this method when the value has to be examined or manipulated in some way before it is passed to the SQL.

Whatever method you choose, you must remember to include any necessary data type qualifiers in the SQL string. In the illustration below, a single quote mark is included in the SQL string either side of the text variable marked with red arrows: This method requires more typing but avoids conflicts and confusion arising from nesting quotes.

Remember that as with "hard-coded" criteria, variables require the correct qualifiers for their data type: It might be because you made a logic error, or got the SQL syntax wrong, or perhaps you just made a typo.

If this results in workable code it might not produce the result you were expecting.NOTE: This article is the fourth in a series about working with XML data in SQL Server. The first three articles cover the XML data type (“Working with the XML Data Type in SQL Server“), its methods (“The XML Methods in SQL Server“), and incorporating XML into database objects (“Incorporating XML into Your Database Objects“).

Are you storing XML in a string datatype (varchar is the most common for that), and then trying to use an XML function on it or put it in an XML typed column/variable?

The function part of this expression is: (state, current)=>state+current state is the value accumulated in the calculation.

A record is a structure with a single row, but multiple columns.

However, the way that record is showed in Query editor is vertical! The main reason is that scrolling to right is always harder than scrolling to down. nqcmd is the ODBC command line tool that always has, and hopefully always will, shipped with OBIEE.
